This page explains how Agenta defines a +tool, the tool types we support, and exactly how each type runs at request time. The question +this page keeps coming back to is *where execution happens*: inside the harness, in a runner +subprocess, back at the Agenta service, or in the browser. The answer is different for each +tool type, and getting it right is what keeps secrets server-side while still letting the +agent act. + +Read the [architecture](architecture.md) and [ports and adapters](ports-and-adapters.md) +pages first. This page assumes the service/runner split and the `/run` wire contract. For the +two harnesses' delivery mechanics in full, see the [Pi adapter](adapters/pi.md) and the +[Claude Code adapter](adapters/claude-code.md). + +## A tool has two lives: declared config and resolved spec + +A tool exists in two forms, and almost every confusion about tools comes from mixing them up. + +1. **The declared config** is what an author commits in `AgentConfig.tools`. It says what the + tool *is*: a reference to a gateway action, an inline snippet, a built-in name. It is + stable, portable, and contains no secrets and no endpoints. +2. **The resolved spec** is what the runner receives on the `/run` wire. It says how to *run* + the tool: the secrets already injected, the callback endpoint already filled in, the + gateway reference already turned into a server-side slug. It is per-run and never committed. + +The service turns the first into the second every run. The runner only ever sees the second. + +The declared models live in `sdks/python/agenta/sdk/agents/tools/models.py`. Every tool config +shares two fields through `ToolConfigBase`, and then a `type` discriminator picks the variant: + +| Config (`type`) | Carries | Example use | +| --- | --- | --- | +| `builtin` | `name` | A harness-native tool such as Pi's `read` or `web_search`. | +| `gateway` | `provider`, `integration`, `action`, `connection`, optional `name` | A Composio action, like `github__create_issue` on a connected account. | +| `code` | `name`, `runtime` (`python`/`node`), `script`, `input_schema`, `secrets` | An inline snippet the author writes, with named vault secrets injected. | +| `client` | `name`, `input_schema` | A tool the browser fulfils, like "ask the user to pick a date." | + +MCP servers are a sibling field, `AgentConfig.mcp_servers`, not a tool type. They are declared +in `sdks/python/agenta/sdk/agents/mcp/models.py` and resolved alongside tools. They are +covered in their own section below. + +## Three orthogonal axes + +The `type` field is one of three independent axes a tool config carries. They do not interact, +and the runner reads each one separately. This is the single idea that makes the tool model +extensible without new branches everywhere. + +- **Executor (`type` at config time, `kind` at runtime):** who fulfils a call. This is the + axis that decides *where execution happens*, and the rest of this page is mostly about it. +- **`needs_approval`:** whether a call waits for a human yes/no before it runs. Default false. +- **`render`:** an optional generative-UI hint so the frontend can draw the call and its + result as something richer than text. + +A code tool can need approval. A gateway tool can carry a render hint. The axes compose. + +The executor axis is named `type` in the committed config and `kind` on the resolved spec. The +rename is deliberate: config talks about where a tool *comes from* (`gateway`), while runtime +talks about *how the runner fulfils it* (`callback`). The mapping is small but worth pinning, +because it is the seam between the two lives of a tool: + +| Declared `type` | Resolved form | Resolved `kind` | +| --- | --- | --- | +| `builtin` | a bare name in `builtin_names` | (none; not a spec) | +| `gateway` | `CallbackToolSpec` with a `call_ref` slug | `callback` | +| `code` | `CodeToolSpec` with secrets in `env` | `code` | +| `client` | `ClientToolSpec` | `client` | + +The resolved specs are also defined in `tools/models.py` (`CallbackToolSpec`, `CodeToolSpec`, +`ClientToolSpec`), and the matching TypeScript shape is `ResolvedToolSpec` in +`services/agent/src/protocol.ts`. A run bundles them as a `ResolvedToolSet`: the built-in +names, the list of specs, and one `ToolCallback` (the endpoint callback tools post back to). + +## How tools get resolved (the service side) + +Resolution is the service's job. The composition point is `resolve_agent_resources` in +`services/oss/src/agent/tools/resolver.py`. It hands the declared configs to the SDK's +`ToolResolver` (`sdks/python/agenta/sdk/agents/tools/resolver.py`), wired with two Agenta +adapters: a `VaultToolSecretProvider` for secrets and an `AgentaGatewayToolResolver` for +gateway tools. The SDK owns the generic algorithm; the service plugs in the Agenta-specific +HTTP calls. The SDK never imports the service. + +Resolution runs per type: + +- **Builtin** passes straight through. The name lands in `builtin_names`. No network call. +- **Code** has its declared `secrets` looked up by name. The service resolves them through + `POST /secrets/resolve` (the named-secret vault path in `services/oss/src/agent/tools/secrets.py`) + and injects the values into the spec's `env`. The script itself is not run here. +- **Client** passes through to a `ClientToolSpec`. There is nothing to resolve server-side. +- **Gateway** is the involved one. `AgentaGatewayToolResolver` + (`services/oss/src/agent/tools/gateway.py`) posts the references to the API's + `POST /tools/resolve`. The API (`api/oss/src/core/tools/service.py`, `resolve_agent_tools`) + validates that the named connection exists, is active, and is authenticated, then enriches + the tool from the Composio catalog with its real description and input schema. It returns a + `call_ref` slug of the form `tools.{provider}.{integration}.{action}.{connection}`. The + resolver wraps each one in a `CallbackToolSpec` and attaches a single `ToolCallback` whose + endpoint is the API's `POST /tools/call`. + +This is what "gateway tools are built at the service level" means in practice. The service +does the connection check and the catalog lookup up front, so a bad connection fails the +invoke immediately instead of failing the model mid-loop, and the agent only ever receives a +name, a schema, and an opaque slug. The Composio key and the connection's auth never leave the +service. + +MCP servers resolve on the same path but only when `AGENTA_AGENT_ENABLE_MCP` is truthy. The +`MCPResolver` injects each server's named secrets into its `env`, the same way code tools get +theirs. By default this is off, so MCP is currently opt-in. + +The whole resolved bundle then rides the `/run` wire: built-in names in `tools`, resolved +specs in `customTools`, the callback in `toolCallback`, and resolved MCP servers in +`mcpServers`. + +## How tools get delivered (the harness fork) + +The runner has to hand resolved tools to a harness, and harnesses do not accept tools the same +way. The runner branches on a capability, `mcpTools`, not on the harness name. A harness that +reports it can take tools over MCP gets them that way; a harness that cannot gets them +natively. Today that splits cleanly into two paths. + +- **Pi takes native tools.** Pi has an extension API, so the runner registers each resolved + spec as a Pi tool directly. In-process this is `buildCustomTools` in + `services/agent/src/engines/pi.ts`; over ACP it is the bundled Pi extension + (`services/agent/src/extensions/agenta.ts`), which does the same registration from inside + Pi. Either way Pi runs the tool body the runner gives it. +- **Claude and other ACP harnesses take MCP.** They cannot accept a native tool, so the runner + exposes the same resolved specs as a small synthetic MCP server named `agenta-tools` + (`services/agent/src/tools/mcp-bridge.ts` launches `services/agent/src/tools/mcp-server.ts`). + This bridge is given only public metadata (names, descriptions, schemas) and a relay + directory. It never receives the `call_ref`, the code, the scoped secrets, or the callback + auth. When the model calls a tool, the bridge relays the request back to the runner, and the + runner runs the private spec from memory. + +Both paths funnel execution through one function, `runResolvedTool` in +`services/agent/src/tools/dispatch.ts`. It is the single place that branches on `kind`, so how +a tool type executes is defined once, not three times. + +## Execution, type by type + +This is the heart of the page. For each tool type, the question is the same: when the model +picks the tool and supplies the arguments, who actually runs it, and where? + +### Gateway tools: the harness calls back to the service + +Execution is a callback. The harness selects the tool and supplies arguments, but the runner +does not run the integration. The tool body POSTs the call to Agenta's `POST /tools/call` +(`services/agent/src/tools/callback.ts`, `callAgentaTool`), sending the `call_ref` slug and +the model's arguments in an OpenAI-style envelope. The API re-resolves the connection, runs the +Composio action through the provider adapter (`execute_tool` in `core/tools/service.py`), and +returns the result, which the runner hands back to the model verbatim. + +So the split is clean: **the harness decides which tool and with what arguments; the service +runs it.** This is the central safety property of the whole tool system. The Composio key and +the connection's auth stay on the service. The agent, the sandbox, and the harness never hold +a credential. They only ever ask Agenta to run a named, pre-validated action. + +There is one transport wrinkle. On Daytona the in-sandbox process cannot reach Agenta over the +network. So the call is relayed through files instead: the in-sandbox tool writes a request +file to a relay directory, the runner (which can reach Agenta) reads it, performs the same +`/tools/call` POST, and writes the answer back (`relayToolCall` in `dispatch.ts`, +`startToolRelay` in `tools/relay.ts`). Same callback, same envelope, different delivery. The +non-Pi MCP bridge uses this same relay even on local runs, because the bridge runs in a +separate process that the runner keeps blind to the private spec. + +### Code tools: the runner runs them locally + +Execution is a local subprocess inside the runner. `runCodeTool` +(`services/agent/src/tools/code.ts`) writes the snippet to a temp file, spawns `python3` or +`node`, passes the model's arguments as JSON on stdin, and reads the JSON result from stdout. +There is no callback. The code runs where the harness runs. + +This is the mirror image of a gateway tool. A gateway tool keeps every secret out of the +sandbox and runs remotely. A code tool needs its secrets *in* the sandbox, so the runner +injects them, but tightly. The child process gets a minimal environment allowlist (`PATH`, +`HOME`, locale, temp dirs) plus only the tool's own declared, resolved secrets. It does not +inherit provider keys, `AGENTA_*` config, or Composio and Daytona variables (`buildChildEnv` +in `code.ts`). The snippet defines a `main` function; Python is called as `main(**inputs)` and +Node as `main(inputs)`. A non-zero exit or a timeout becomes a tool error so the model loop +continues rather than crashing the run. + +### Client tools: the browser fulfils them across a turn boundary + +Execution happens in the browser, not in the runner at all. A client tool is never run +in-sandbox; `runResolvedTool` throws if one is ever dispatched there, and the MCP bridge filters +client tools out of its advertised list. Instead, when the harness calls a client tool, the +runner emits an `interaction_request` event of kind `client_tool`. The `/messages` egress +projects it to a browser component, the browser runs it, and the result returns in the next +`/messages` turn, matched back by id. This is the cross-turn human-in-the-loop path, the same +mechanism approvals use. A client tool is the right type whenever only the user's environment +can answer: their location, a file on their machine, a confirmation only they can give. + +### Built-in tools: the harness runs them natively + +Execution is the harness's own. A built-in tool is just a name. The runner adds it to the +session's allowlist and Pi runs its own implementation of `read`, `write`, `web_search`, and so +on. Nothing is resolved and nothing is delivered. Note that built-ins are a Pi concept here; +they are not delivered to non-Pi harnesses over ACP, which bring their own native tool set. + +### MCP servers: a server process the daemon launches + +Execution happens in a separate server process. A declared MCP server is resolved server-side +(secrets injected into its `env`) and, for MCP-capable harnesses, passed to the ACP daemon as a +stdio server (`toAcpMcpServers` in `services/agent/src/engines/sandbox_agent.ts`). The daemon +launches the server's `command` with the resolved `env`, and the harness talks to it over the +MCP protocol. Two limits apply today: MCP is gated behind `AGENTA_AGENT_ENABLE_MCP`, and Pi's +ACP adapter does not forward user MCP servers, so MCP currently reaches Claude-style harnesses +only. + +## Approval and rendering + +These are the other two axes, and they ride alongside execution rather than changing where it +happens. + +**`needs_approval`** gates a call on a human answer. Only permission-gating harnesses honor it. +Claude over ACP raises a permission request, which the runner surfaces as an +`interaction_request` of kind `permission` and answers through a `PolicyResponder` +(`services/agent/src/responder.ts`). With no human at the keyboard, the policy auto-approves by +default because the tools are backend-resolved and trusted, and a per-run policy or env +override can flip it to deny. Pi has no permission concept, so the flag is a no-op there. + +**`render`** is a generative-UI hint. The runner does not act on it; it copies the hint from the +spec onto the `tool_call` and `tool_result` events so the egress can project it to the frontend +without a spec lookup. The hint can name a prebuilt component, ship rendered source, or carry a +declarative UI spec (`RenderHint` in `protocol.ts`). + +## The whole picture + +| Tool type | Resolves to | Who executes | Where | Secret handling | +| --- | --- | --- | --- | --- | +| Built-in | a name | the harness | in the harness | none | +| Gateway | `callback` spec + `call_ref` | the Agenta service | back at the service (`/tools/call`), relayed via files on Daytona | key and connection auth stay server-side | +| Code | `code` spec + `env` | the runner | a local subprocess | only the tool's own secrets, scoped to the child | +| Client | `client` spec | the browser | the user's browser, next turn | none | +| MCP | resolved server + `env` | a server process | a stdio child the daemon launches | secrets injected into the server env | + +## Where this lives + +| Concern | File | +| --- | --- | +| Declared tool configs | `sdks/python/agenta/sdk/agents/tools/models.py` | +| Resolved tool specs | `sdks/python/agenta/sdk/agents/tools/models.py` (`ResolvedToolSet`) | +| MCP config | `sdks/python/agenta/sdk/agents/mcp/models.py` | +| SDK resolution algorithm | `sdks/python/agenta/sdk/agents/tools/resolver.py` | +| Service resolution composition | `services/oss/src/agent/tools/resolver.py` | +| Gateway resolver (calls `/tools/resolve`) | `services/oss/src/agent/tools/gateway.py` | +| Named-secret resolution (`/secrets/resolve`) | `services/oss/src/agent/tools/secrets.py` | +| API resolve + execute | `api/oss/src/core/tools/service.py`, `api/oss/src/apis/fastapi/tools/router.py` | +| Wire contract | `services/agent/src/protocol.ts`, `sdks/python/agenta/sdk/agents/utils/wire.py` | +| Runtime dispatch (branch on `kind`) | `services/agent/src/tools/dispatch.ts` | +| Callback transport | `services/agent/src/tools/callback.ts` | +| Code execution | `services/agent/src/tools/code.ts` | +| Pi native delivery | `services/agent/src/engines/pi.ts`, `services/agent/src/extensions/agenta.ts` | +| MCP bridge for non-Pi harnesses | `services/agent/src/tools/mcp-bridge.ts`, `services/agent/src/tools/mcp-server.ts` | +| Permission policy | `services/agent/src/responder.ts` | + +## Status and known gaps + +- MCP server resolution is off unless `AGENTA_AGENT_ENABLE_MCP` is truthy, so MCP is opt-in. +- Pi's ACP adapter does not forward user-declared MCP servers; MCP reaches Claude-style + harnesses only. +- `needs_approval` is honored only by permission-gating harnesses (Claude over ACP).

It studies OpenCode's architecture and compares it to the agent +workflow we are building. The goal is to learn from a mature, independent design that solves +the same problem we are solving: run a coding agent behind an API, let many clients drive it, +and stream the run back. + +OpenCode is an open-source AI coding agent built by SST. It has a client-server shape. One +server exposes an HTTP API. Many clients connect over that API: a terminal UI, a desktop app, +a VS Code extension, and a web app. The server runs the agent loop, talks to model providers, +runs tools, and owns conversation state. The clients render. This is close to what we are +designing, so it is worth studying carefully. + +The source moved during this research. The repo is now +[`anomalyco/opencode`](https://github.com/anomalyco/opencode) on the `dev` branch, not +`sst/opencode`. The codebase is also mid-migration from a v1 model to a v2 model. The v1 model +matches the public docs and the DeepWiki summaries. The v2 model lives in a new `packages/core` +and a new `packages/server`, and it is a different and more interesting design. This note +covers the v2 model as the current direction, and flags where v1 still applies. Where the docs +were thin, the note reads the source directly and says so. + +## What the docs cover and what the code shows + +The published docs at [opencode.ai/docs](https://opencode.ai/docs) describe the v1 system: an +HTTP server with an SSE event stream, sessions, messages, a "parts" union, providers, tools, +agents, and modes. Most third-party summaries describe the same v1 shape. + +The `dev` branch tells a newer story. The team has rewritten the core onto +[Effect](https://effect.website) and an event-sourced session model. Sessions are now durable +event aggregates. Messages are projections built from those events. The new server lives in its +own package and is defined with a typed HTTP API DSL. This note treats that v2 code as the real +current design and notes the confidence level on each claim. + +## Services and packages + +OpenCode is a monorepo. The server is TypeScript on the Bun runtime. The terminal UI is Go. +Most other surfaces are TypeScript and SolidJS. The packages that matter for this comparison +are below. File counts come from the `dev` tree and just signal weight. + +| Package | Role | +| --- | --- | +| `packages/core` | The domain. Sessions, messages, events, tools, providers, agents, the agent loop, and the SQLite store. Built on Effect and Drizzle ORM. | +| `packages/server` | The HTTP API. Route groups, handlers, auth, CORS, middleware. Defined with Effect's `HttpApi` DSL, which also emits the OpenAPI spec. | +| `packages/sdk` | The generated TypeScript client. `js/src/gen` is generated from the OpenAPI JSON. There is a v1 client and a v2 client. | +| `packages/tui` | The terminal client, written in Go. It is a normal API client, not privileged. | +| `packages/app` | Shared SolidJS UI logic for the desktop and web surfaces, including the event reducer and session cache. | +| `packages/desktop` | The Electron desktop app. | +| `packages/llm` | Provider-facing types: tool content, provider metadata, message normalization for model APIs. | +| `packages/plugin` | The plugin interface and hook surface. | +| `packages/console`, `packages/enterprise` | Cloud control plane, sharing, billing, and hosted services (OpenCode Zen and Go). Out of scope here. | + +The shape to take away: one server process owns the agent and the state, and every client, +including OpenCode's own TUI, is just an API consumer. The server is the only thing that talks +to model providers and runs tools. This is stated in the architecture overview on +[DeepWiki](https://deepwiki.com/sst/opencode) and confirmed by the package layout in the repo. + +### What each part cares about + +- The **server** cares about the API contract and request handling.

This is where the real model lives. Source: + [`packages/core/src/session`](https://github.com/anomalyco/opencode/tree/dev/packages/core/src/session). +- The **clients** care about rendering the event stream and sending prompts. They hold no + authoritative state. They keep a local cache that the event stream keeps in sync. Source: + [`packages/app/src/context/global-sync`](https://github.com/anomalyco/opencode/tree/dev/packages/app/src/context/global-sync). +- The **SDK** cares about turning the OpenAPI spec into typed methods and an SSE subscription. + It is generated, not hand-written. + +### External dependencies + +- **Model providers.** The server integrates 75+ providers through the Vercel AI SDK and + `@ai-sdk/*` adapters, plus an OpenAI-compatible adapter for local models. Each provider has a + small plugin under [`packages/core/src/plugin/provider`](https://github.com/anomalyco/opencode/tree/dev/packages/core/src/plugin/provider). + Source: [providers doc](https://opencode.ai/docs/providers/). +- **Storage.** SQLite through Drizzle ORM, with write-ahead logging and a busy timeout.

The server can also gate itself with `OPENCODE_SERVER_PASSWORD`. + Source: [server doc](https://opencode.ai/docs/server/). +- **LSP.** An optional `lsp` tool and LSP client integration for code intelligence. Source: + [tools doc](https://opencode.ai/docs/tools/). +- **MCP servers.** External tool servers wired in through config. Source: + [tools doc](https://opencode.ai/docs/tools/). + +## Layers + +The system layers cleanly from the model up to the screen. + +1. **Provider layer.** Adapters that speak each model API and normalize messages before they go + out. Source: [`packages/llm`](https://github.com/anomalyco/opencode/tree/dev/packages/llm) + and the `ProviderTransform.normalizeMessages` step described on + [DeepWiki](https://deepwiki.com/sst/opencode). +2. **Core domain layer.** The session aggregate, the event log, the agent loop, the tool + registry, and the projections. This layer is provider-agnostic and transport-agnostic. +3. **Server layer.** The HTTP API and the SSE event stream. It exposes the domain over the + wire and emits the OpenAPI spec. +4. **SDK layer.** Generated typed clients over the API. +5. **Client layer.** The TUI, desktop, web, and editor extensions. They render the stream and + send prompts. +6. **Plugin layer.** A cross-cutting extension surface with hooks at well-defined points + (tool execution, permissions, file edits, session lifecycle). Source: + [plugins doc](https://opencode.ai/docs/plugins/). + +The key boundary is between core and everything else. Core does not know about HTTP. The server +does not know how the agent loop works. The clients do not know how the model is called. + +## The protocol + +The transport is HTTP plus Server-Sent Events. There is no websocket and no custom binary +protocol. The full API is published as an OpenAPI 3.1 spec at `/doc`, and the TypeScript SDK is +generated from it. Source: [server doc](https://opencode.ai/docs/server/) +and [OpenAPI spec on DeepWiki](https://deepwiki.com/sst/opencode/7.2-openapi-specification). + +The generator itself is in motion. The v1 SDK used `@hey-api/openapi-ts` over the published +OpenAPI JSON. The team is now replacing that with a private `@opencode-ai/httpapi-codegen` +compiler that "reflects Effect `HttpApi` contracts directly, without OpenAPI or Hey API" and can +"compile once into shared contract IR, then emit either a rich Effect client or a zero-Effect +Promise/fetch client." Source: +[PR #33445, `feat(sdk): add HttpApi client codegen`](https://github.com/anomalyco/opencode/pull/33445). +The destination is the same in both designs. The API contract is written once in code, and the +client is derived from it, so client types cannot drift from the server. The detail to note is +that they decided OpenAPI itself was an intermediate artifact they could drop, and went straight +from the typed API definition to the client. + +The v2 routes live under `/api`. The ones that matter for a session turn: + +| Method and path | Purpose | +| --- | --- | +| `POST /api/session` | Create a session. Returns `SessionV2.Info`. | +| `GET /api/session` | List sessions with cursor pagination. | +| `GET /api/session/:id` | Get one session. | +| `POST /api/session/:id/prompt` | Admit one prompt and schedule the agent loop.

The prompt call does not return the assistant's answer. + +1. The client creates a session, or reuses an id, then opens one long-lived SSE connection to + `GET /api/event`. The stream opens with a `server.connected` event and then carries every + server event. +2. The client posts a prompt to `POST /api/session/:id/prompt`. The server **admits** the + prompt as a durable event and **schedules** the agent loop. It then returns a small + `SessionInput.Admitted` acknowledgment with a sequence number. The OpenAPI summary for this + route says it plainly: "Durably admit one session input and schedule agent-loop execution + unless resume is false." Source: + [`groups/session.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/server/src/groups/session.ts). +3. The agent loop runs on the server. As it runs, it publishes session events: step started, + text started, text deltas, text ended, tool input started, tool called, tool success, step + ended, and so on. These events flow out over the one SSE stream the client already holds. +4. The client renders by folding those events into its local message cache. When it needs the + settled transcript, it pages `GET /api/session/:id/message`, which returns projected + messages rebuilt from the same events. + +So the request that starts the turn and the stream that carries the turn are decoupled. The +prompt is a command. The output is an event stream. The transcript is a projection. The +[handler](https://github.com/anomalyco/opencode/blob/dev/packages/server/src/handlers/session.ts) +just calls `session.prompt(...)`, and the core +[`Session.prompt`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session.ts) +admits the input and calls `execution.wake(sessionID)`. + +Why split admission from execution. OpenCode made this explicit in +[PR #30785, `refactor(core): make v2 session inputs event sourced`](https://github.com/anomalyco/opencode/pull/30785). +Before it, "an accepted prompt lived only in `session_input`" until it became model-visible, so +pending work "could not be reconstructed from synchronized Session history." The fix splits a +prompt into two durable facts: `PromptAdmitted` records "accepted intent" with its delivery mode, +and `PromptPromoted` (now folded into the existing `prompted` event, per +[PR #33443](https://github.com/anomalyco/opencode/pull/33443)) records when the prompt becomes +"model-visible history" at a safe runner boundary. That is the stated reason the POST returns an +acknowledgment rather than the answer. The accepted work is already a durable event the moment +the call returns, and the loop is scheduled separately. A client that drops can re-read the log +and see that its prompt was accepted, even before the agent has produced a token. + +### Steering and queueing + +The prompt payload carries a `delivery` field with two values, `steer` and `queue`, defaulting +to `steer`. Source: +[`session/input.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/input.ts). +A run coordinator serializes execution per session and lets a new prompt either interrupt the +in-flight turn (`steer`) or wait for it to finish (`queue`). The coordinator exposes `run`, +`wake`, and `interrupt`. Its own doc comment states the contract: it "serializes execution for +each key while allowing different keys to run concurrently." `run` "starts execution while idle or +joins the active execution," `wake` "registers one coalesced follow-up after newly recorded +work," and `interrupt` "stops active execution and waits for its cleanup." Source: +[`session/run-coordinator.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/run-coordinator.ts). +This is how a user types a follow-up mid-turn and the agent reacts to it without a second +connection. + +This feature has a long, telling history. The original problem was blunt: a prompt sent while the +session was busy "would be rejected with a `BusyError`," so "users couldn't send messages while +the agent was mid-task." +[PR #19156, `feat: queue pending prompts when session is busy`](https://github.com/anomalyco/opencode/pull/19156) +replaced the rejection with a queue and "injects [queued prompts] as user messages at the start +of each loop iteration, before loading message history." Steering then arrived as the second lane. +[PR #26199, `feat: Add server-owned Steer/Queue pending messages`](https://github.com/anomalyco/opencode/pull/26199) +made the pending state server-owned, "inspired by Codex," so that "the server owns pending state, +ordering, pause/resume, deletes, lane changes, and delivery." The stated reason for server +ownership is to prevent "inconsistent snapshots between clients and runtime status." Later work +([PR #33247](https://github.com/anomalyco/opencode/pull/33247), +[PR #33104](https://github.com/anomalyco/opencode/pull/33104)) added "mid-stream interrupts for +steer, allowing the AI to smoothly pause without wiping the turn," plus a "wrap" mode that lets +the agent "gracefully finish its current step/tool execution before halting for the queued +message." The lesson in this arc: steering is not a feature you bolt onto the transport at the +end. It started as an error and became a first-class, server-owned, event-sourced lane only after +the team had a durable session log to anchor it to. + +## Session, message, and parts model + +This is the section we care about most. OpenCode's v2 model is event-sourced. Read it as three +layers stacked on each other: events at the bottom, projected messages in the middle, the +session aggregate on top. + +### The session aggregate + +A session is identified by a branded id with a `ses_` prefix and a descending ULID, so newer +sessions sort first. A session belongs to one project and has an optional `parentID` for +sub-agent and forked conversations. The `Info` record carries title, optional active `agent`, +optional `model` reference, rolled-up `cost` and `tokens`, a `location` (directory and optional +workspace), and lifecycle timestamps. Source: +[`session/schema.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/schema.ts). + +The session is not a row that the loop mutates directly. It is the head of an event log keyed by +`sessionID`. Every meaningful thing that happens publishes a durable event against that +aggregate. + +### The event log + +Events are the source of truth. Each event has an `evt_` id with an ascending ULID, a `type`, a +`data` payload, an optional `location`, and, when durable, a `{ aggregateID, seq, version }` +block. Durable events get a monotonic `seq` per aggregate, which is what gives the log ordering +and replay. Source: +[`event.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/event.ts). + +Session events are namespaced `session.next.*`. The set includes prompt admission, agent and +model switches, step lifecycle, text lifecycle, reasoning lifecycle, tool lifecycle, shell, +synthetic and system context, retries, and compaction. Source: +[`session/event.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/event.ts). + +The streaming pattern inside the events is the clever part. Each content kind has a +`started` / `delta` / `ended` triad. The `delta` events are deliberately **not** durable. A +comment in the source says it directly: "Stream fragments are live-only; Text.Ended is the +replayable full-value boundary." So the deltas carry the live typing experience and never hit +the log, while the `ended` event carries the full settled value that replay and projection use. +The same split applies to reasoning and to tool input. Tool execution adds a `progress` event +for bounded mid-run checkpoints, with a comment warning tools not to persist every stdout chunk. +Source: +[`session/event.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/event.ts). + +### The projected messages + +Messages are not stored as the model writes them. They are projections rebuilt from the event +log by a projector, then written to a `MessageTable` and `PartTable` in SQLite. Source: +[`session/projector.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/projector.ts). + +The v2 message is a tagged union, discriminated by `type`. The variants are `user`, +`assistant`, `synthetic`, `system`, `shell`, `compaction`, `agent-switched`, and +`model-switched`. Source: +[`session/message.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/message.ts). + +The notable shift from v1: in v2 the assistant message does **not** hold a flat array of +sibling "parts." It holds a `content` array of `AssistantContent`, itself a tagged union of +`text`, `reasoning`, and `tool`. The assistant message also carries `agent`, `model`, optional +`snapshot` start and end markers, `finish`, `cost`, and a `tokens` breakdown that includes +cache read and write. Source: +[`session/message.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/message.ts). + +The tool content is a state machine, not a flat record. `ToolState` is a tagged union over +`status`: + +- `pending`: the call exists, only the raw input string is known. +- `running`: input is parsed, `structured` output and `content` are accumulating. +- `completed`: final `content`, `structured` output, `result`, and `outputPaths`. +- `error`: an error plus whatever `content` and `result` were produced. + +Source: +[`session/message.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/message.ts). + +So the lifecycle is consistent end to end. The event log emits `tool.input.started`, +`tool.input.delta`, `tool.input.ended`, `tool.called`, `tool.progress`, then `tool.success` or +`tool.failed`. The projector folds those into a single tool entry whose `state` walks +`pending → running → completed | error`. The client renders the same transition live from the +event stream and can reconcile against the projection. + +The user message carries a structured `Prompt`: `text`, optional `files`, and optional `agents`. +A `FileAttachment` has a uri, mime, optional name and description, and an optional source range. +An `AgentAttachment` is an `@`-mentioned subagent. Source: +[`session/prompt.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/prompt.ts). + +For completeness: the v1 model, which the public docs still describe, used a separate `Part` +union (`TextPart`, `ToolPart`, `FilePart`, `ReasoningPart`, `StepStartPart`, `StepFinishPart`, +`SnapshotPart`, `PatchPart`, `AgentPart`, `SubtaskPart`, `CompactionPart`, and more) hung off a +message `info` record. Source: +[message and part types on DeepWiki](https://deepwiki.com/sst/opencode). The v2 design absorbs +those concerns into events plus a smaller projected message. Confidence: the v1 part list is +from DeepWiki and the docs, not re-read from current source; the v2 model is read directly from +`packages/core`. + +### Agents and modes + +An agent in OpenCode is a named configuration: a model, a system prompt, a permission ruleset, a +mode, optional step cap, and provider request overrides. Source: +[`agent.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/agent.ts) and the +[agents doc](https://opencode.ai/docs/agents/). The default agent id is `build`. + +The `mode` field is `primary`, `subagent`, or `all`. Primary agents are the ones a user drives +directly, like `build` and `plan`. Subagents are spawned by a primary agent or `@`-mentioned by +the user, like `general`, `explore`, and `scout`. The session records its active agent, and the +client can switch it mid-conversation with `POST /api/session/:id/agent`, which the server +records as a `session.next.agent.switched` event. So "mode" is not a separate concept layered on +top of agents. It is a property of the agent, and the active agent is session state. Source: +[agents doc](https://opencode.ai/docs/agents/). + +Permissions live on the agent as a ruleset over tool categories (`read`, `edit`, `bash`, +`glob`, `grep`, `task`, and others) with values `allow`, `ask`, or `deny`, and glob patterns for +finer control. The `plan` agent ships with edits and bash set to `ask`. When a tool needs +approval, the server emits a permission event and waits. Source: +[agents doc](https://opencode.ai/docs/agents/) and +[tools doc](https://opencode.ai/docs/tools/). + +## Why v2: the rationale and the lessons + +This section is the point of the note. For each major v2 choice, it pins down the problem the +choice removed, separates OpenCode's stated reason from inference, and names the lesson for our +own design. A note on provenance first. The event-sourced core was built by jlongster (James +Long), the author of Actual Budget, who is known for putting event sourcing and CRDTs into a +shipping product and wrote the widely-read piece +[Using CRDTs in the Wild](https://archive.jlongster.com/using-crdts-in-the-wild). That pedigree +shows in the design. The first sync PR frames the model in exactly the terms an event-sourcing +practitioner would. This is context for the why, not a substitute for it. + +### The event-sourced session log + +**Stated reason.** The founding PR, +[#17814, `feat(core): initial implementation of syncing`](https://github.com/anomalyco/opencode/pull/17814), +says it directly: "This is a system inspired by event sourcing that tracks mutations of +session-related data through events." The design constraints are spelled out and are the key to +why it stays simple: "We don't need distributed clocks. We only support a single writer and many +readers. Events can be total ordered via a sequential integer, guaranteed to update atomically via +sqlite." The payoff is also stated: "After this PR I will add more routes for replaying these +events which will let you recreate sessions." A second PR, +[#30785](https://github.com/anomalyco/opencode/pull/30785), gives the sharper reason for pushing +even pending input into the log. Before it, accepted-but-not-yet-run prompts "could not be +reconstructed from synchronized Session history." + +**The v1 problem it removed.** In v1 the session was rows the loop mutated in place. State lived +in whatever happened to be written, so there was no single ordered record to replay, and a client +could not rebuild a session it had not watched live. Reconnection and multi-client sync had no +foundation to stand on. + +**Lesson for us.** The single-writer, many-reader shape is the whole reason event sourcing here is +cheap, not academic. One server process owns each session, so a per-session monotonic integer is +enough ordering. No vector clocks, no consensus. This matches our setup. Our service is the single +writer for a session. If we adopt server-owned history, an append-only event log with a per-session +`seq`, stored in our normal database, gives us replay and reconnection without distributed-systems +machinery. The constraint that makes it work is one we already satisfy. + +### Projecting messages from events, not storing a wire format + +**Stated reason.** The replay route promised in #17814 became the projector. The projector reads +the durable events and upserts message and part rows with `onConflictDoUpdate`, which the analysis +of the source confirms is "idempotent message/part insertion, enabling safe event replay." Token +and cost usage is applied with reversible signed arithmetic so a removed or edited part can be +backed out. The one load-bearing comment in the projector states a real invariant: "A newer turn +supersedes stale incomplete rows; never resume an older assistant projection." Source: +[`session/projector.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/projector.ts). + +**The v1 problem it removed.** v1 stored messages and a large `Part` union close to a client wire +format. That couples the stored shape to one renderer and to one moment in the schema's life. The +v2 split makes the events the truth and the message table a cache you can rebuild. When the message +shape changes, you re-project. You do not migrate stored transcripts. + +**Lesson for us.** This is the cleanest argument against our current convert-on-the-edge approach. +We take Vercel `UIMessage` in, run, and convert `AgentEvent` back to Vercel parts out. That bakes +one client's wire format into the round trip. If history becomes server-owned, store neutral events +as truth and project to Vercel, ACP, or AG-UI on read. The projection is a pure function of the +log, so it is safe to replay, safe to change, and the same log serves every egress format. The +idempotent-upsert and reversible-usage details are worth copying verbatim. They are what make +re-projection and edits safe. + +### The live-delta versus durable-`ended` boundary + +**Stated reason.** The split is documented in a source comment, not just inferred: "Stream +fragments are live-only; Text.Ended is the replayable full-value boundary." The tool-progress +comment is just as explicit about the cost it avoids: "Replayable bounded running-tool state. +Tools should checkpoint semantic transitions or at a bounded cadence, not persist every +stdout/stderr chunk." Source: +[`session/event.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/event.ts). + +**The problem it removes.** If every token delta were durable, the log would bloat in proportion to +output length, replay would get slow, and the disk would carry data no reader ever needs after the +turn settles. Persisting only the settled `ended` value keeps the log proportional to the number of +content segments, not the number of tokens. + +**Lesson for us.** We already emit start, delta, and end events. The missing discipline is on the +write path. Persist only the boundary, and treat deltas as live-only transport. We get smooth +streaming and a small replayable log at once. This is the lesson to take first, because it is a +rule about what to write, not a new subsystem. + +### The tool state machine + +**Stated reason.** None found. The `ToolState` tagged union over `status` +(`pending → running → completed | error`) carries no explaining comment, and no PR was found that +argues for it. Source: +[`session/message.ts`](https://github.com/anomalyco/opencode/blob/dev/packages/core/src/session/message.ts). + +**Inference (marked as inference, not their stated reason).** The shape itself is the argument. Each +status carries exactly the fields valid in that state: `pending` has only the raw `input` string; +`running` adds parsed input, `structured` output, and accumulating `content`; `completed` adds +`result` and `outputPaths`; `error` swaps in an `error`. A flat record with all fields optional +would let illegal combinations typecheck, such as a `completed` call with no result, or a `pending` +call that somehow has output. Encoding the state in a discriminant makes those states +unrepresentable. The same union appears in the events, in the projected message, and on the client, +so all three agree on "what state is this call in" by construction. This is the standard reason to +prefer a tagged union over optional fields, and it is consistent with the rest of this codebase, +which leans on tagged unions everywhere. We are confident in the benefit; we just did not find +OpenCode stating it. + +**Lesson for us.** Model tool lifecycle as a tagged union in the data, mirrored in the event, the +stored row, and the client. It removes a class of "which fields are set" bugs and gives every +surface one definition of the call's state. + +### Steering and the per-session run coordinator + +**Stated reason.** Covered in the steering section above. The short version: prompts during a busy +turn used to fail with `BusyError` ([#19156](https://github.com/anomalyco/opencode/pull/19156)), so +queueing replaced rejection, then server-owned steer/queue lanes +([#26199](https://github.com/anomalyco/opencode/pull/26199), "inspired by Codex") replaced ad-hoc +client handling to stop "inconsistent snapshots between clients and runtime status." The coordinator +"serializes execution for each key while allowing different keys to run concurrently." + +**The v1 problem it removed.** No way to talk to a working agent. The choice was reject or race. The +coordinator gives a single serialized execution per session with two well-defined entry points for +a follow-up. + +**Lesson for us.** Design the coordinator and the `steer | queue` flag in from the start, not after. +The OpenCode history shows the cost of retrofitting. They shipped rejection, then queueing, then +steering, then mid-stream interrupt, then graceful wrap, across a dozen PRs. We can read the +endpoint and design straight to it: one per-session serialized runner, a delivery flag on the +prompt, and the injection happening at a safe loop boundary, "before loading message history." + +### Defining the API in code so the client is generated + +**Stated reason.** Partly stated, partly inferred. The docs state the mechanism ("All types are +generated from the server's OpenAPI specification") but not the why. The newer +[PR #33445](https://github.com/anomalyco/opencode/pull/33445) states the direction more plainly: +reflect the Effect `HttpApi` contract directly and emit the client from it, "without OpenAPI or Hey +API," compiling "once into shared contract IR" that can emit a rich or a zero-dependency client. + +**Inference on the benefit.** The reason this matters is drift. When the API is written once in code +and the client is derived from it, the client types cannot diverge from the server. Hand-written +clients drift the moment a route changes and nobody updates the client. OpenCode did not have to +state this; it is why anyone generates a client from a contract. Their extra move is the lesson: +they treated even OpenAPI as a replaceable middle artifact and went straight from the typed API +definition to the client. + +**Lesson for us.** Keep one source of truth for the wire contract and generate the typed client from +it. We do not need Effect to get this. A typed API definition that emits both the spec and the +client is enough. The point is that the contract is authored once and the client is derived, never +written twice. + +### The migration strategy, as its own lesson + +This is not a single design choice, but it is the most reusable thing in the history. OpenCode did +not big-bang the rewrite. The first sync PR put event writing "behind a feature flag so that we can +easily change the schema if we need to," ran a temporary dual-write of v1 and v2 paths, kept "the db +mutations exactly the same for each of the write paths," and shipped it "through beta first." +Source: [PR #17814](https://github.com/anomalyco/opencode/pull/17814). The transitional +`session.next.*` event namespace and the parallel v1/v2 SDK clients are the visible residue of that +approach. The lesson for us, if we move to server-owned history, is to dual-write and flag-gate the +new event log beside the current path, project from it, and cut over only once the projection +matches the live behavior. We do not have to choose between cold replay and event sourcing on day +one. + +## Learnings and interesting things + +**The prompt is a command, not a request-response.** The HTTP call that starts a turn returns an +acknowledgment with a sequence number, and all output arrives on a separate, already-open event +stream. This is the cleanest answer I have seen to a problem we keep hitting: how do you start a +long agent turn over HTTP without holding a request open, and how do you reconnect mid-turn. You +do not stream the answer back on the POST. You admit the work and let the client read the event +stream. A reconnecting client just re-reads from a sequence number. + +**Event sourcing with a live/durable split.** The deltas are live-only and the `ended` events +are the durable, replayable boundary. This gets you smooth token streaming and a clean, +compact, replayable log at the same time, without writing every token to disk. The durable +events project into messages, so the transcript is always reconstructable and the streaming UI +is always cheap. This is a strong pattern and the one I would borrow first. + +**Tool state as a state machine in the data model.** `pending → running → completed | error` is +encoded in the schema as a tagged union, not implied by which fields happen to be set. The same +state shows up in events, in the projection, and on the client. There is one source of truth for +"what state is this tool call in," and the type system enforces the transitions. + +**The server is the single owner of state, and even the first-party TUI is just a client.** +There is no privileged in-process path for OpenCode's own UI. This forces the API to be complete +and keeps every surface honest. It is the discipline that makes a desktop app, a web app, and an +editor extension all viable against the same server. + +**Generate the SDK from the API, and define the API in code.** The server is written with +Effect's typed `HttpApi` DSL. That same definition emits the OpenAPI spec, and the spec +generates the SDK. The contract is written once and the client types cannot drift from it. + +**Steering is first-class.** `delivery: steer | queue` plus a per-session run coordinator means +a follow-up prompt can interrupt or queue behind the current turn. Mid-turn interruption is a +data-model decision, not a hack bolted onto the transport. + +**What I would be cautious about.** The whole core is built on Effect, which is a large bet on a +functional effect system and a steep on-ramp for contributors. The codebase is also visibly +mid-migration, with v1 and v2 session models, two SDK clients, and `session.next.*` event names +that read like a transitional namespace. The SDK generator is moving too, from `@hey-api/openapi-ts` +over OpenAPI toward a custom Effect-contract codegen +([PR #33445](https://github.com/anomalyco/opencode/pull/33445)), so the exact toolchain is not +settled. The public docs lag the code by a full architecture generation, which made this research +slower and means anyone reading their docs is reading the old model. Cloning the event-sourced core +without the Effect machinery would take real work. The good news from the migration history is that +they did this incrementally behind a feature flag with a dual-write, not as a big-bang rewrite, so +the path is reproducible without betting the whole product on it at once. + +## Comparison to ours + +Our design is documented under +[`docs/design/agent-workflows`](../README.md). The relevant pages are +[architecture](../architecture.md), [protocol](../protocol.md), +[ports-and-adapters](../ports-and-adapters.md), and [sessions](../sessions.md). + +### Where we already agree + +- **Client-server with a thin transport and a real core.** Our SDK owns neutral ports and DTOs + in `sdks/python/agenta/sdk/agents/`, and the service is a thin consumer. OpenCode splits + `core` from `server` the same way. Both keep the agent loop out of the HTTP layer. +- **A neutral intermediate event model.** We emit `AgentEvent` objects and project them into + one or more egress formats (Vercel UI Message Stream today, ACP and AG-UI planned). OpenCode + emits `session.next.*` events and projects them into messages and into the SSE stream. Both of + us treat the live run as a stream of typed events, not as one blob. +- **Lifecycle events with start, delta, and end.** Our protocol maps `message`, `thought`, and + reasoning to start/delta/end parts. OpenCode does the same with its `started`/`delta`/`ended` + triads. We arrived at the same shape independently. +- **Tool calls and results as discrete events with an approval path.** Our `tool_call`, + `tool_result`, and `interaction_request` events line up with OpenCode's tool lifecycle plus + permission events. Both of us model human approval in the event stream. +- **Tool delivery is harness-specific, but the event is neutral.** We resolve tools server-side + and let the runner execute them. OpenCode has a tool registry and a permission ruleset. The + external event shape stays uniform in both. + +### Where they differ, and what it suggests + +**Sessions: durable and server-owned versus cold replay.** This is the biggest gap. Our runtime +is cold. Each turn creates a fresh session, runs one `/run`, and tears it down. The model only +sees prior context because the client re-sends the full history every turn. Our `SessionStore` +is a port with only a `NoopSessionStore` behind it, and `/load-session` returns an empty list. +Source: [sessions](../sessions.md). OpenCode is the opposite. The server owns the conversation +as a durable event log, the client sends only the new prompt, and history is a query. Their +model is what our [sessions](../sessions.md) page calls future work. Their event log is also a +concrete answer to our open "session snapshot" question: you do not snapshot opaque harness +state, you keep an event log you can replay and project. + +**Prompt response: acknowledge-and-stream versus stream-on-the-POST.** Today our `/messages` +streams the Vercel UI Message Stream as the SSE body of the POST that carried the prompt. That +ties the turn to one open request. OpenCode admits the prompt, returns a sequence-numbered +acknowledgment, and streams everything on a separate long-lived `GET /api/event` connection. If +we want reconnect-mid-turn, multiple watchers on one session, or a turn that outlives a flaky +client connection, their split is the design to copy. It would mean adding a durable per-session +event stream endpoint alongside `/messages`, and treating the prompt POST as a command that +returns an id. + +**Message model: projection-from-events versus convert-on-the-edge.** We convert Vercel +`UIMessage` input into neutral `Message` objects on the way in, run, and convert `AgentEvent` +back into Vercel parts on the way out. OpenCode never converts a transcript on the edge. The +transcript is always a projection of the durable event log, so any client can page it and any +client can rebuild it. If we move to server-owned history, we should store events or neutral +messages as the source of truth and project to Vercel, ACP, or AG-UI on read, rather than +storing one client's wire format. + +**Steering: built-in versus absent.** We have no mid-turn steering or queueing concept. Our turn +is one cold `/run`. OpenCode's `delivery: steer | queue` plus the run coordinator gives +interrupt and queue semantics for free. When we add warm or server-owned sessions, we will want +the same two verbs, and it is cheaper to design the event and the coordinator in from the start +than to retrofit them. + +**Agent and model as session state versus per-run config.** OpenCode records the active agent +and model on the session and switches them with their own events. Our harness, model, and +sandbox selection ride on each `/run` as `RunSelection` and `AgentConfig`. Source: +[ports-and-adapters](../ports-and-adapters.md). For a chat that spans many turns, treating agent +and model as switchable session state, with an event when they change, is the better fit. Our +[agent-template](../agent-template.md) split already points this way; OpenCode shows it working. + +**One harness versus many.** Here we differ on purpose, and it is our advantage. OpenCode owns +its agent loop. There is one harness, written in TypeScript on the AI SDK. We run external +harnesses (Pi, Claude) over a backend and harness port, with local and Daytona sandboxes. +Source: [architecture](../architecture.md). That makes our event model harder, because we have +to normalize several harness wire formats into one `AgentEvent`, but it also lets us run agents +we did not write. OpenCode does not have that constraint, so it can make the event log and the +loop one tightly-coupled thing. We should not copy that coupling. Our neutral `AgentEvent` +boundary is the right call for a multi-harness platform. + +### Concrete takeaways for our session, message, and protocol design + +1. **Make the server own session history as an event log, and make the transcript a + projection.** Store neutral events or neutral messages as the source of truth. Project to + Vercel, ACP, or AG-UI on read. This directly fills the gap our + [sessions](../sessions.md) page documents and avoids storing one client's wire format. The why: + we are a single writer per session, so a per-session monotonic `seq` in our normal database + buys replay and reconnection with no distributed-systems machinery, exactly as OpenCode's + [#17814](https://github.com/anomalyco/opencode/pull/17814) lays out. +2. **Split the prompt from the stream.** Add a durable per-session event stream the client + subscribes to, and turn the prompt POST into an admit-and-schedule command that returns an + id and a sequence number. Keep `/messages` as a convenience streaming path, but make the + event stream the reconnectable source of truth. The why: OpenCode made accepted input a durable + `PromptAdmitted` event so pending work survives a dropped client and is reconstructable from + history ([#30785](https://github.com/anomalyco/opencode/pull/30785)). +3. **Adopt the live-delta, durable-boundary split.** Keep token deltas live-only and persist a + settled `ended` value per text, reasoning, and tool-input segment. We already emit the start, + delta, and end events; the missing half is persisting only the boundary, not every delta, so + the log stays small and replayable. The why is stated in their source: deltas are "live-only," + the `ended` event is "the replayable full-value boundary," and tools must not "persist every + stdout/stderr chunk." +4. **Model tool state as an explicit state machine in the data, not as optional fields.** A + `pending → running → completed | error` tagged union, mirrored in the event, the stored + message, and the client, removes a class of "which fields are set" bugs. The why is inference, + not their stated reason: only the fields valid in a state exist in that state, so illegal + combinations cannot typecheck. +5. **Plan for steering and queueing now.** When we move off cold replay, design a per-session + coordinator and a `steer | queue` delivery flag into the prompt contract from the start. The + why: OpenCode shipped this across a dozen PRs starting from a plain `BusyError` rejection + ([#19156](https://github.com/anomalyco/opencode/pull/19156)). We can design straight to the + endpoint they reached, and make pending state server-owned to avoid client/runtime drift + ([#26199](https://github.com/anomalyco/opencode/pull/26199)). +6. **Keep agent and model as session state once chat spans turns.** Record the active agent and + model on the session and emit an event on change, instead of re-sending them on every run. +7. **Migrate incrementally, behind a flag, with a dual-write.** If we move to server-owned + history, do not rewrite in one cut. Flag-gate the event log beside the current path, project + from it, verify the projection matches live behavior, then cut over. This is how OpenCode + shipped the rewrite without freezing the product ([#17814](https://github.com/anomalyco/opencode/pull/17814)). + +The honest summary: OpenCode has already built the durable, server-owned, event-sourced session +model that our docs describe as future work, and it pairs that with an acknowledge-and-stream +protocol that solves reconnection cleanly. Their constraint is simpler than ours, since they own +their one agent loop, so we should borrow their session and protocol mechanics while keeping our +neutral multi-harness `AgentEvent` boundary, which is the thing their design does not need and +we do. + +## Sources + +- OpenCode docs: [overview](https://opencode.ai/docs/), [server](https://opencode.ai/docs/server/), + [sdk](https://opencode.ai/docs/sdk/), [agents](https://opencode.ai/docs/agents/), + [tools](https://opencode.ai/docs/tools/), [plugins](https://opencode.ai/docs/plugins/), + [providers](https://opencode.ai/docs/providers/). +- Repository: [`anomalyco/opencode`](https://github.com/anomalyco/opencode) (`dev` branch).

Describes the active-stack code as built. | +| **Scope** | The wire boundary between the Python agent service and the TypeScript runner sidecar. | +| **Audience** | Anyone changing the `/run` payload, the transports, the event model, or either runner engine. | +| **Related** | [protocol.md](../protocol.md) (all public surfaces), [architecture.md](../architecture.md) (runtime shape), [ports-and-adapters.md](../ports-and-adapters.md) (SDK ports). This page is the deep dive on the internal `/run` slice that those pages summarize. | + +## 1. Summary + +The agent workflow runs in two processes. A Python process (the **agent service**) decides +*what* to run: it parses config, resolves provider secrets and tools, and threads trace +context. A Node process (the **runner sidecar**) decides *how* to run it: it drives a coding +harness (Pi or Claude) and streams back what happened. + +Those two processes talk over one contract: a `POST /run` request carrying a single agent +turn, and a structured result describing the turn. The same contract is delivered two ways +(HTTP to a running sidecar, or a subprocess CLI in a source checkout) and in two modes +(one-shot JSON, or live NDJSON). This RFC specifies that contract precisely: the transports, +the request and result schemas, the event model, the streaming framing, the error model, and +the versioning rules. + +The boundary is hand-mirrored on both sides and pinned by golden fixtures. The single most +important operational rule is in [Section 11](#11-versioning-and-the-change-both-sides-rule): +any field change touches Python, TypeScript, the golden fixtures, and both contract tests in +the same PR. + +## 2. Why a two-process boundary exists + +The split is not incidental. It is load-bearing for three reasons. + +1. **The harnesses are Node libraries.** Pi, Claude Code, and the `sandbox-agent` package + have no Python SDK. The agent loop has to run in Node. The rest of Agenta is Python. The + boundary is where those two worlds meet. +2. **Secret isolation.** The sidecar deliberately does not inherit the full service + environment. Provider keys and tool credentials are resolved by the service and passed + only inside the scoped `/run` payload that needs them. The sidecar sees a key because the + service chose to send it for that one run, not because it shares the service's env. +3. **Separation of concerns.** "What to run" (Agenta config, vault secrets, gateway tools, + trace context) stays in the service. "How to run it" (harness lifecycle, ACP, sandbox + creation, event shaping) stays in the runner. The `/run` contract is the only thing both + sides must agree on. + +## 3. Roles and terminology + +| Term | Meaning | +| --- | --- | +| **Agent service** | The Python FastAPI process. Owns config parsing, secret/tool resolution, tracing, and the public `/invoke` and `/messages` surfaces. Code: `services/oss/src/agent/`. | +| **Runner sidecar** | The Node process that runs the agent loop. Serves `GET /health` and `POST /run`. Code: `services/agent/`. Compose service name: `sandbox-agent`. | +| **Backend (SDK)** / **engine (runner)** | The same axis seen from two sides. The SDK `Backend` adapter (`InProcessPiBackend`, `SandboxAgentBackend`) hard-codes its engine id and serializes `/run`. The runner dispatches on that id (`pi` or `sandbox-agent`) to a TS engine (`engines/pi.ts`, `engines/sandbox_agent.ts`). | +| **Harness** | Which agent runs inside the engine: `pi`, `claude`, or `agenta`. | +| **Sandbox** | Where the run happens: `local` or `daytona`. | +| **Transport** | How the `/run` JSON is delivered: HTTP or subprocess CLI. | +| **Mode** | One-shot (one JSON result) or streaming (NDJSON records). | + +A clarification that the naming invites confusion on: **"in-process" means in-process to the +Node runner, not to Python.** `InProcessPiBackend` still crosses the `/run` wire. It just +tells the runner to drive the Pi SDK directly (`engines/pi.ts`) instead of starting the +`sandbox-agent` daemon and an ACP adapter (`engines/sandbox_agent.ts`). Both backends use the +identical transports and wire; they differ only in the `backend` field value and therefore in +which TS engine the runner picks. + +## 4. Topology and transport selection + +``` +browser / workflow client + | + | POST /invoke or POST /messages + v ++-------------------------------+ +| agent service (Python) | +| services/oss/src/agent/app.py | +| parse config | +| resolve secrets + tools | +| pick backend, build /run | ++-------------------------------+ + | + | ONE of two transports, chosen by whether a URL is set: + | + | (a) HTTP POST {AGENTA_AGENT_RUNNER_URL}/run + | (b) spawn pnpm exec tsx src/cli.ts (stdin -> stdout) + v ++-------------------------------+ +| runner sidecar (Node) | +| services/agent/src/server.ts | <- (a) +| services/agent/src/cli.ts | <- (b) +| dispatch on `backend` | +| "pi" -> runPi | +| "sandbox-agent"-> runSandboxAgent ++-------------------------------+ +``` + +The service always constructs a `SandboxAgentBackend` (`select_backend` in `app.py`). The +transport is a deployment choice, made by `_runner_config.resolve_runner_command` and the +adapter's `_deliver`: + +- **HTTP**, when `url` is set. The service reads it from `AGENTA_AGENT_RUNNER_URL` + (`config.runner_url()`). This is the deployed-container path: the sidecar is its own + service and the Python process calls it in-network. +- **Subprocess CLI**, when `url` is unset. The service passes `cwd` from `config.runner_dir()` + (overridable with `AGENTA_AGENT_RUNNER_DIR`), and the adapter spawns the default command + `pnpm exec tsx src/cli.ts` in that directory. This is the source-checkout / local-dev path. + +`resolve_runner_command` fails fast with `AgentRunnerConfigurationError` if it gets neither a +`url`, an explicit `command`, nor a `cwd` that actually contains `src/cli.ts`. There is no +silent "do nothing" runner. + +### Engine identity + +The engine id is not in the user-facing config. Each backend hard-codes it +(`InProcessPiBackend._ENGINE = "pi"`, `SandboxAgentBackend._ENGINE = "sandbox-agent"`) and +stamps it on the payload as `backend`. The subprocess transport also exports it as the +`AGENT_BACKEND` env var, as a backstop. At dispatch time the **payload's `backend` field +wins**; `AGENT_BACKEND` is only the fallback when the field is absent, and the runner's own +default is `sandbox-agent`. + +### Relevant environment variables + +| Variable | Side | Effect | +| --- | --- | --- | +| `AGENTA_AGENT_RUNNER_URL` | service | Set -> HTTP transport to this base URL. Unset -> subprocess CLI. | +| `AGENTA_AGENT_RUNNER_DIR` | service | Overrides the runner checkout dir used for the subprocess transport. | +| `AGENTA_AGENT_RUNNER_TIMEOUT_SECONDS` | service | Per-call transport timeout. Default `180`. | +| `AGENT_BACKEND` | runner | Fallback engine when the request omits `backend`. Default `sandbox-agent`. | +| `PORT` | runner | HTTP listen port. Default `8765`. | + +## 5. The runner HTTP surface + +The sidecar serves two routes from Node's built-in `http` server (no framework). Source: +`services/agent/src/server.ts`. + +### `GET /health` + +Returns runner identity so a client can detect an incompatible runner before the first run. + +```json +{ + "status": "ok", + "runner": "0.1.0", + "protocol": 1, + "engines": ["pi", "sandbox-agent"], + "harnesses": ["pi", "claude", "agenta"] +} +``` + +`protocol` is the MAJOR of the `/run` wire contract (`PROTOCOL_VERSION` in `version.ts`). +`runner` is the package build version, which is independent of the protocol. See +[Section 11](#11-versioning-and-the-change-both-sides-rule). + +### `POST /run` + +Body is an `AgentRunRequest` ([Section 7](#7-the-run-request)). Response depends on the +`Accept` header: + +| `Accept` | Mode | Response | +| --- | --- | --- | +| absent or anything but NDJSON | one-shot | One `AgentRunResult` JSON. HTTP `200` when `ok`, `500` when not. | +| `application/x-ndjson` | streaming | An NDJSON stream of `StreamRecord` lines, always under HTTP `200`. | + +Other status codes from the route: + +| Status | Cause | +| --- | --- | +| `400` | Request body is present but not valid JSON. | +| `404` | Any path other than `GET /health` or `POST /run`. | +| `500` | One-shot run returned `ok:false`, or an unexpected error in the request listener. | + +An empty body parses to `{}` rather than erroring. The runner then runs with all-default +fields, which is what the contract tests rely on. + +## 6. Transports in detail + +There are four delivery functions, two per transport, in +`sdks/python/agenta/sdk/agents/utils/ts_runner.py`. The backend's `_deliver` (one-shot) and +`_deliver_stream` (streaming) pick HTTP vs subprocess by the same `if self._url:` rule. + +### One-shot + +- **HTTP** (`deliver_http`): `POST {url}/run` with the JSON body, parse the JSON response. + Any status `>= 400` raises `RuntimeError("Agent runner HTTP {status}: {body}")` so a + transport failure is a clear error, not an opaque parse failure. +- **Subprocess** (`deliver_subprocess`): spawn the command, write the JSON to stdin, read + stdout. stdout carries the result and nothing else; logs go to stderr. Empty stdout raises + with the exit code and stderr tail. Non-JSON stdout raises with both stream tails. + +### Streaming (NDJSON) + +- **HTTP** (`deliver_http_stream`): `POST {url}/run` with `Accept: application/x-ndjson`, + yield each parsed line as it arrives. The `async with` client closes the connection when + the generator is closed or cancelled, which the runner observes as a client disconnect and + turns into run cancellation ([Section 9](#9-cancellation-and-timeouts)). +- **Subprocess** (`deliver_subprocess_stream`): spawn the command with `--stream`, write the + request to stdin, read stdout line by line against a deadline. A `finally` kills the child + if the consumer stops early, so a dropped stream never leaks a runner process. + +Both streaming transports enforce the terminal-result invariant +([Section 8](#8-streaming-framing)): if the stream drains without a `result` record, they +raise `RuntimeError("Agent runner stream ended without a terminal result record")`. + +### Symmetry guarantee + +The one-shot and streaming paths return the *same* `AgentRunResult` shape. The streaming +terminal record carries the identical result object the one-shot path would return, so the +Python side parses both with the same `result_from_wire`. The only difference: on the +streaming path the terminal result's `events` is emptied, because the events were already +delivered live (see [Section 8](#8-streaming-framing)). + +## 7. The `/run` request + +Type: `AgentRunRequest` in `services/agent/src/protocol.ts`, hand-mirrored in +`sdks/python/agenta/sdk/agents/utils/wire.py` (`request_to_wire`). camelCase on the wire. + +| Field | Type | Meaning | +| --- | --- | --- | +| `backend` | string | Engine id: `pi` or `sandbox-agent`. Set by the adapter, not the user. The runner dispatches on it. | +| `harness` | string | `pi`, `claude`, or `agenta`, subject to backend support. | +| `sandbox` | string | `local` or `daytona`. The in-process Pi path is local only. | +| `sessionId` | string \| null | External conversation id. The runtime is still cold; history arrives in `messages`, not by resuming a warm session. | +| `agentsMd` | string | Instructions injected as the agent's `AGENTS.md`. | +| `model` | string | Requested model id (`gpt-5.5`) or `provider/id` (`openai-codex/gpt-5.5`). | +| `messages` | ChatMessage[] | Conversation so far. The runner picks the latest user turn and replays the rest. | +| `secrets` | object | Provider keys as env vars (`{"OPENAI_API_KEY": "..."}`), resolved from the vault by the service. | +| `trace` | TraceContext \| null | Trace context so the run nests under the caller's `/invoke` span. | +| `tools` | string[] | Built-in tool names to enable (harness-shaped). | +| `customTools` | ResolvedToolSpec[] | Resolved runnable tools (gateway callback, code, or client). | +| `toolCallback` | ToolCallbackContext | Where callback tools POST back. Required when `customTools` is set. | +| `mcpServers` | McpServerConfig[] | User-declared MCP servers, secret env already injected. Omitted entirely when there are none. | +| `permissionPolicy` | string | `auto` (default) or `deny`, for permission-gating harnesses. | +| `systemPrompt` | string | Pi only: replace Pi's base system prompt. `AGENTS.md` is still appended after it. | +| `appendSystemPrompt` | string | Pi only: append to Pi's base prompt without replacing it. | +| `prompt` | string | Optional explicit latest turn. Falls back to the last user message in `messages`. | +| `skills` | string[] | Bundled skill directory names to force-load (the Agenta harness). | + +### How the request is assembled + +`request_to_wire` does not list tool, prompt, or MCP fields literally. It spreads three +harness-shaped helpers off the config object: + +- `config.wire_tools()` shapes `tools` / `customTools` / `toolCallback` / `permissionPolicy` + per harness. Pi sends built-ins plus native specs and no gating; Claude sends MCP-delivered + specs plus the permission policy. This is why the Pi and Claude golden requests differ. +- `config.wire_prompt()` adds `systemPrompt` / `appendSystemPrompt` only for harnesses that + expose them (Pi). It is empty otherwise. +- `config.wire_mcp()` adds `mcpServers` only when the user declared some, so a tool-free run's + payload is byte-for-byte unchanged. + +The engine id is passed in explicitly by the caller (the adapter), because each adapter +hard-codes its own. + +### ResolvedToolSpec + +A tool the service already resolved. Three orthogonal axes: + +- `kind` (the executor): `callback` POSTs back through Agenta's `/tools/call` (gateway tools; + the Composio key stays server-side); `code` runs `code` in a sandbox subprocess with `env` + (scoped resolved secrets); `client` is fulfilled by the browser across a turn boundary. + Absent means `callback` for back-compat. +- `needsApproval`: gate the call on a human yes/no. +- `render`: a generative-UI hint (`component`, `source`, or `spec`). + +`callRef` is set for `callback` tools only (the slug the bridge sends back). `runtime` / `code` +/ `env` are set for `code` tools. Provider keys and connection auth never ride on the spec; +they stay server-side. + +### Worked example (Pi) + +From `golden/run_request.pi.json`: + +```json +{ + "backend": "pi", + "harness": "pi", + "sandbox": "local", + "sessionId": "sess-1", + "agentsMd": "You are a helpful assistant.", + "model": "openai-codex/gpt-5.5", + "messages": [{"role": "user", "content": "hi"}], + "secrets": {"OPENAI_API_KEY": "sk-test"}, + "trace": { + "traceparent": "00-0af7651916cd43dd8448eb211c80319c-b7ad6b7169203331-01", + "endpoint": "https://otlp.example/v1/traces", + "authorization": "Access tok-123", + "captureContent": true + }, + "tools": ["read", "write"], + "customTools": [ + { + "name": "get_user", + "description": "Get a user", + "inputSchema": {"type": "object", "properties": {}}, + "callRef": "tools__composio__github__GET_THE_AUTHENTICATED_USER__github-tvn", + "kind": "callback" + } + ], + "toolCallback": { + "endpoint": "https://api.example/tools/call", + "authorization": "Access tok-123" + }, + "permissionPolicy": "auto", + "systemPrompt": "You are Pi.", + "appendSystemPrompt": "Be terse." +} +``` + +The Claude golden (`run_request.claude.json`) differs as the harness shaping predicts: no +`tools` built-ins beyond an empty list, no Pi prompt overrides, `permissionPolicy: "deny"`, +and `backend: "sandbox-agent"`. + +## 8. The `/run` result and the event model + +Type: `AgentRunResult` in `protocol.ts`, parsed by `result_from_wire` in `wire.py`. + +| Field | Type | Meaning | +| --- | --- | --- | +| `ok` | bool | Success flag. `false` makes the Python side raise (see below). | +| `output` | string | Final assistant text. What the playground renders. | +| `messages` | ChatMessage[] | Structured assistant messages for the turn. | +| `events` | AgentEvent[] | Structured event log. Empty on the streaming path. | +| `usage` | AgentUsage | Token/cost totals, rolled onto the caller's workflow span. | +| `stopReason` | string | Why the turn ended, when the harness reports it. | +| `capabilities` | HarnessCapabilities | What the harness was probed to support this run. | +| `sessionId` | string | Session id, carried forward by the adapter for the next turn. | +| `model` | string | Model actually used. | +| `traceId` | string | Trace id of the run (the caller's trace when a traceparent was passed). | +| `error` | string | Failure message, set when `ok` is `false`. | + +### `ok` is a hard boundary + +`result_from_wire` raises `RuntimeError(f"Agent run failed: {error}")` whenever `ok` is +falsey. A failed run never reaches the model loop as an empty reply; it surfaces as a clear +Python exception. This holds on both the one-shot and streaming paths, because both parse the +terminal result with the same function. + +### The event model + +`AgentEvent` mirrors the ACP `session/update` variants the runner surfaces. Two text families +coexist and a consumer sees one or the other for a given block, never both: + +- **Coalesced**: `message` and `thought` carry a whole block. These appear in the one-shot + result's `events` log, because the non-streaming path has no per-token granularity to + recover. +- **Lifecycle / delta**: `message_start` / `message_delta` / `message_end` and the matching + `reasoning_*` trio are emitted live on the streaming path. A consumer that sees the delta + family for a block never also sees a coalesced `message` for it. + +The full variant set: + +| Event | Carries | +| --- | --- | +| `message` / `thought` | `text` (coalesced block) | +| `message_start/delta/end` | `id`, `delta` (live assistant text) | +| `reasoning_start/delta/end` | `id`, `delta` (live reasoning) | +| `tool_call` | `id?`, `name?`, `input?`, `render?` | +| `tool_result` | `id?`, `output?`, `data?` (structured), `isError?`, `render?` | +| `interaction_request` | `id`, `kind` (`permission` / `input` / `client_tool`), `payload?`.

The `run_result.ok.json` golden includes a typeless event specifically to pin +that drop behavior. + +### Capabilities + +`HarnessCapabilities` is probed from the runtime (`sandbox-agent` `AgentCapabilities`) and +returned in the result. The runner branches on these flags rather than on the harness name: +`textMessages`, `images`, `fileAttachments`, `mcpTools`, `toolCalls`, `reasoning`, `planMode`, +`permissions`, `usage`, `streamingDeltas`, `sessionLifecycle`. + +### Worked example (success) + +From `golden/run_result.ok.json`, abridged: + +```json +{ + "ok": true, + "output": "Hello!", + "messages": [{"role": "assistant", "content": "Hello!"}], + "events": [ + {"type": "message", "text": "Hello!"}, + {"type": "usage", "input": 10, "output": 5, "total": 15, "cost": 0.001}, + {"type": "done", "stopReason": "end_turn"} + ], + "usage": {"input": 10, "output": 5, "total": 15, "cost": 0.001}, + "stopReason": "end_turn", + "capabilities": {"textMessages": true, "toolCalls": true, "usage": true}, + "sessionId": "sess-42", + "model": "gpt-5.5", + "traceId": "trace-abc" +} +``` + +A failure is just `{"ok": false, "error": "model exploded"}`. + +## 8b. Streaming framing + +When a caller asks for live delivery (HTTP `Accept: application/x-ndjson`, or the CLI +`--stream` flag), the runner writes newline-delimited JSON. Each line is a `StreamRecord`: + +```ts +type StreamRecord = + | { kind: "event"; event: AgentEvent } + | { kind: "result"; result: AgentRunResult }; +``` + +The framing rules are exact and load-bearing: + +1. One `{kind:"event"}` record flushes the moment its `AgentEvent` is built. +2. The run ends with **exactly one** `{kind:"result"}` record. This holds for success and for + failure: a thrown engine error becomes `{kind:"result", result:{ok:false, error}}`, not a + dropped connection. +3. The terminal result's `events` is emptied (`{...result, events: []}`) because the events + were already delivered live. A streaming consumer must rebuild the log from the `event` + records, not expect it on the result. +4. A stream that ends without a terminal `result` is an error. Both Python streaming + transports raise rather than hand the caller a resultless run. + +The browser never sees this NDJSON. The `/messages` egress converts it to a Vercel UI Message +Stream over SSE. NDJSON is strictly the Python-to-runner internal framing. + +## 9. Cancellation and timeouts + +**Cancellation** is wired end to end on the streaming path: + +- HTTP: the server listens on the *response* `close` (not the request, whose body is already + fully read) and aborts an `AbortController` when the client drops. The signal is passed into + `runSandboxAgent`. On the Python side, closing or cancelling the async generator closes the + httpx connection, which the runner sees as that disconnect. +- Subprocess: the streaming transport's `finally` kills the child if the consumer breaks or is + cancelled. + +One asymmetry worth knowing: the HTTP server passes the abort `signal` to `runSandboxAgent` +but not to `runPi`, and the CLI dispatch passes no signal at all. In-process Pi and all CLI +runs are cancelled by transport teardown (connection close or process kill), not by a +cooperative in-engine signal. + +**Timeouts** are transport-level on the Python side, from +`AGENTA_AGENT_RUNNER_TIMEOUT_SECONDS` (default 180s). The one-shot HTTP path uses the httpx +client timeout; the one-shot subprocess path uses `asyncio.wait_for` and kills the child on +expiry; the streaming subprocess path enforces a per-read deadline. There is no separate +server-side run timeout in the runner today; a run that never ends is bounded by the caller's +transport timeout. + +## 10. Error model + +Failures fall into two clean classes. + +1. **Transport failures**: the runner could not be reached or did not produce a parseable + result. HTTP `>= 400`, empty stdout, non-JSON stdout, a timeout, or a stream with no + terminal result. Each raises a `RuntimeError` with a specific message and (for subprocess) + the exit code and stderr tail. +2. **Run failures**: the runner ran but the turn failed. The result is `{"ok": false, + "error": "..."}`, which `result_from_wire` turns into a `RuntimeError("Agent run failed: + ...")`. On the one-shot HTTP path this also carries HTTP `500`; on the streaming path it + arrives as a normal terminal `result` record under HTTP `200`. + +The runner hardens its own process against background crashes: when running as the server +entrypoint it installs `unhandledRejection` and `uncaughtException` handlers that log and keep +serving, instead of letting one run's stray rejection (for example a `sandbox-agent` adapter +install or a Daytona preview SSE failing off the awaited path) kill the process and take every +in-flight request with it. + +## 11. Versioning and the "change both sides" rule + +The contract is intentionally duplicated, not shared through an imported module. Keeping the +request/result/event/capability types in `protocol.ts` (rather than one runner importing them +from the other) is what lets `engines/pi.ts` and `engines/sandbox_agent.ts` stay peers, and it +keeps Python free of a TS dependency. + +Duplication is made safe by golden fixtures and two contract tests: + +- Fixtures: `sdks/python/oss/tests/pytest/unit/agents/golden/` (`run_request.pi.json`, + `run_request.claude.json`, `run_result.ok.json`, `run_result.error.json`). +- Python asserts them in `test_wire_contract.py`. +- TypeScript asserts them in `tests/unit/wire-contract.test.ts`, which also has a compile-time + key guard, so a drifted `protocol.ts` fails `tsc`. + +**The rule:** any change to a request field, result field, event kind, or capability touches, +in the same PR: the golden fixture, `protocol.ts`, `wire.py`, and both contract tests. + +`PROTOCOL_VERSION` (`version.ts`) is the wire MAJOR, surfaced on `GET /health`. It is meant to +let a client refuse a runner whose major it does not understand. Today this is an available +affordance, not an enforced guard: no Python caller probes `/health` or checks the major +before the first `/run`. Wiring that probe is open work +([Section 12](#12-known-gaps-and-open-questions)). + +## 12. Known gaps and open questions + +These are properties of the boundary as built, not bugs to fix inside this RFC. They are the +candidate agenda for follow-up design. + +- **The runtime is cold.** Every turn is one `/run`: create a session, run, tear down. + `sessionId` rides the wire and is carried forward, but multi-turn context comes from + replaying `messages`, not from a warm daemon or a persisted model session. ACP + `session/load`, fork, and warm reuse are not wired. +- **No schema validation on the runner.** `POST /run` JSON-parses the body and runs with + whatever fields are present (an empty body becomes `{}`). There is no structural validation + or rejection of unknown fields at the boundary; correctness rests on the golden tests, not + on a runtime guard. +- **The version skew guard is not consumed.** `/health` exposes `protocol`, but nothing checks + it. A client and runner can silently disagree across a major bump. +- **Pi prompt overrides are dropped on the ACP path.** `systemPrompt` / `appendSystemPrompt` + serialize into the request, but the `sandbox-agent` Pi engine does not deliver them yet. + They only take effect on the in-process Pi engine. +- **Cancellation is uneven.** Only `runSandboxAgent` over HTTP receives the abort signal. + In-process Pi and all CLI runs rely on transport teardown. +- **Remote MCP is not executed.** `mcpServers` carries `http` transport on the wire, but the + active-stack runner path executes local `stdio` MCP only. Remote servers are skipped. +- **No run-level timeout in the runner.** Only the caller's transport timeout bounds a run. +- **Result/event size is unbounded.** The one-shot result inlines the whole `events` log and + `messages`. There is no paging or cap on the boundary. + +## 13.

"Loading +JSON and round-tripping it through an interface" validates nothing at runtime. The contract +test needs real runtime checks, in two layers: + +1. Add `tests/utils/golden.ts` that loads the shared fixtures from + `sdks/python/oss/tests/pytest/unit/agents/golden/` (relative path from the runner, read + at test time). No copying; one source of truth. +2. **Runtime validation, not type assertion.** Either (a) introduce a zod (or equivalent) + schema that mirrors `protocol.ts` and `parse()` each golden fixture in + `tests/unit/wire-contract.test.ts`, or (b) write explicit structural assertions (required + keys present, types correct, the `ok` discriminant). Option (a) doubles as a real runtime + guard the server can use on inbound requests; option (b) is lighter but only a test. +3. **Type-level check, separately.** Use vitest's `expectTypeOf` (or a `tsd`-style check) so + a fixture that drifts from `AgentRunRequest` fails `typecheck`, independent of the runtime + assertions. +4. Exercise the pure helpers in `protocol.ts` (`messageText`, `resolvePromptText`, + `resolveRunSessionId`) against fixture-derived inputs. +5. Note in `protocol.ts` and Python `test_wire_contract.py` that the contract is now pinned + from both sides, so future editors look both ways. + +Done when: editing a field name in `protocol.ts` without updating the fixtures (or vice +versa) fails this test, at runtime and at typecheck. + +## Phase 4 — Structure and maintainability (progressive, no big bang) + +Adopt as the runner is touched, not in one sweep. + +1. **Add `services/agent/AGENTS.md`** (with a `CLAUDE.md` symlink, matching `web/`, `api/`). + Keep it short: the package is a standalone pnpm project; how to run/serve/test/typecheck; + where runner code goes (`src/{engines,tools,tracing}`) and where tests go + (`tests/unit`, fixtures in `tests/utils`); the wire contract is mirrored in Python + `wire.py` and pinned by golden fixtures, so change both sides; vitest is the runner. + Add a thin `.claude/rules` / `.cursor/rules` pointer if the repo expects one. +2. **Local typecheck gate (optional).** The root `.husky/pre-commit` already runs prettier + and gitleaks repo-wide. Optionally add `pnpm --dir services/agent typecheck` for changed + TS, or leave the gate to CI to keep commits fast. Recommendation: CI is the gate; skip + the local hook unless commits regularly land type errors. +3. **Linting (optional, phase-2 nice-to-have).** There is no eslint outside `web/`. + `prettier` (global hook) covers formatting. A small `typescript-eslint` flat config for + `services/agent` would add real value for async runner code (`no-floating-promises`, + `no-misused-promises`). Treat as optional; `tsc --strict` + prettier is an acceptable + floor. +4. **Extract a testability seam (Codex).** `server.ts` and `cli.ts` wire transport to the + engines inline, so HTTP/CLI behavior can only be tested with a live harness. Export + `createServer(runAgent)` and `runCli(runAgent)` that take the engine as an argument. Then + unit tests inject a fake engine returning a deterministic `AgentRunResult` and cover + `/health`, invalid-JSON handling, `POST /run`, NDJSON record ordering, and CLI exit codes, + with no Pi/Claude/sandbox-agent. This is the highest-value structural change for testability. +5. **Decompose the two large files opportunistically.** When next editing `engines/sandbox_agent.ts` + or `tracing/otel.ts`, pull a cohesive seam into its own module and unit-test it, the way + `responder.ts` was extracted from `sandbox_agent.ts`. Not a scheduled refactor. + +## Phase 5 — Make it a versioned, supportable service (Codex's main gap) + +The review's core point: the plan above makes the runner testable but does not make it a +first-class deployable. These items make the SDK and the sidecar safe to release on their +own cadences. Scope and sequence with the platform/release owner; some are bigger than a +half-day. + +1. **Protocol/version negotiation.** Add a `protocolVersion` (major) to the wire and have + `GET /health` (or a new `/capabilities`) return `runnerVersion`, `protocolVersion`, + supported engines, and harnesses. The Python adapter probes once and refuses an + incompatible major before the first run. Today `/health` returns only `{status:"ok"}` and + `package.json` is `0.0.0`. +2. **Release ownership.** Decide whether the sidecar version tracks the Agenta release or is + versioned independently, and stop shipping `0.0.0`. The SDK should pin a compatible runner + *protocol* range, not a package-version equality. +3. **Sidecar image publishing.** No CI publishes the runner image today (only api/web/services + images are built, e.g. in `42-railway-build.yml`). Add a build/publish job so the HTTP + sidecar (the production boundary) is actually distributable. +4. **Local code-tool execution policy.** `runCodeTool` scopes secret env, but a `code` tool + still runs an arbitrary `python3`/`node` process in the sidecar. State the sandbox, + resource, and network policy (it is already sandboxed in Daytona; the local/in-sidecar + path needs an explicit stance), so this is a deliberate posture, not an oversight. +5. **Config hygiene.** `services/oss/src/agent/app.py` reads `AGENTA_AGENT_*` via raw + `os.getenv`. The repo convention (root `AGENTS.md`) is to add config to + `api/oss/src/utils/env.py` and consume the shared `env` object. Align it. +6. **Fix the stale `local.py` docstring.** `sdks/python/.../adapters/local.py` says the Pi + runner is "shipped inside the wheel," which is not true today and is the likely source of + the wheel confusion. Either implement that path deliberately (see the packaging options in + the answer to question 1) or correct the docstring to match reality. + +## Sequencing and ownership + +- Phases 1 to 3 are independent of any runtime change and can land as one small PR or three + tiny ones.

However `sdks/python/.../adapters/local.py` (the + unimplemented `LocalBackend`) says the Pi runner is "the bundled JS runner ... shipped + inside the wheel." That is aspirational and NOT YET IMPLEMENTED, but it is almost certainly + the source of the "is the TS part of the SDK / wheel" worry. The future-local-backend + question (bundle a built JS runner into the wheel vs require Docker/npm) is real and + undecided; see plan Phase 5 item 6 and the distribution options in status.md. + +Scripts present in `package.json` today: `run:cli`, `serve`, `serve:watch`, +`build:extension`, `login`. There is **no `test`, no `typecheck`, no `lint`, no `format`.** + +## 3. How it is tested today (the gap) + +There are 8 test files under `services/agent/test/`: + +``` +code-tool.test.ts continuation.test.ts mcp-servers.test.ts responder.test.ts +skills.test.ts stream-events.test.ts tool-bridge.test.ts tool-dispatch.test.ts +``` + +They are genuinely good tests in content. The problem is entirely in how they run: + +- Each file is a **standalone script** using `node:assert/strict`, with bare `{ ... }` + blocks for grouping and a `console.log("...: ok")` at the end. The header of each says + `Run: pnpm exec tsx test/.test.ts`. +- There is **no runner and no aggregation.** Running "the test suite" means running eight + commands by hand. A failure is a thrown assertion and a non-zero exit on one file; there + is no summary, no count, no `--watch`, no filtering, no coverage, no junit. +- They run in **no CI workflow.** `12-check-unit-tests.yml` has a `run-services-unit-tests` + job, but it only looks at `services/oss/tests/pytest/unit` (Python) and runs + `uv run python run-tests.py`. It never installs Node or touches `services/agent`. Every + vitest mention in CI refers to `web/packages`. So the runner's tests have never gated a + PR. +- There is **no TS-side contract test.** `protocol.ts` says the contract is pinned by + golden fixtures under `sdks/python/oss/tests/pytest/unit/agents/golden/` and checked by + the Python `test_wire_contract.py`. That guards the Python mirror (`wire.py`). Nothing on + the TS side asserts that `protocol.ts` still accepts those fixtures, so the runner can + drift from the contract and only Python would notice. + +## 4. What the repo already standardizes for TypeScript tests + +We do not need to invent a convention. The frontend already has one, and there is a written +spec: + +- **vitest is the repo's TS unit runner.** `web/packages/*` (agenta-shared, entities, + entity-ui, playground, annotation) each ship a `vitest.config.ts` and these scripts: + + ```jsonc + "test": "pnpm run test:unit", + "test:unit": "vitest run", + "test:watch": "vitest", + "test:coverage": "vitest run --coverage", + "typecheck": "tsc --noEmit" + ``` + + Config (from `agenta-shared/vitest.config.ts`): `include: ["tests/unit/**/*.test.ts"]`, + `environment: "node"`, `reporters: ["default", "junit"]` writing `test-results/junit.xml`, + and v8 coverage. This is exactly the shape a Node service wants. + +- **CI runs them generically.** The web job runs `pnpm -r --if-present test:unit` across + workspace packages and publishes `web/packages/*/test-results/junit.xml` via the + `publish-unit-test-result-action`. Any package that defines `test:unit` is picked up; the + rest are skipped. A new package following the same script names slots in for free. + +- **There is a folder-layout spec.** `docs/designs/testing/testing.structure.specs.md` + defines runner-first layout: `/tests//{unit,integration,acceptance,utils}` + plus `manual/` and `legacy/`. In practice the vitest packages collapse this to + `tests/unit/**/*.test.ts` (one runner, so no `vitest/` level). The agent runner's current + flat `test/` directory matches neither; aligning it to `tests/unit/` matches the closest + precedent (web packages) and the spec. + +## 5. Python-to-TypeScript mental model + +For mapping the tooling onto what the SDK/API side already does: + +| Concern | Python (api/, sdks/) | TypeScript (services/agent) | +|----------------------|---------------------------|------------------------------------| +| Package manager | `uv` | `pnpm` (own lockfile) | +| Run a script | `uv run python x.py` | `pnpm exec tsx x.ts` | +| Test runner | `pytest` | **vitest** (proposed) | +| One command to test | `uv run python run-tests.py` | `pnpm test` (proposed) | +| Type checker | `mypy` / pyright | `tsc --noEmit` (configured, unrun) | +| Formatter | `ruff format` | `prettier` (runs repo-wide in hooks) | +| Linter | `ruff check` | none today (eslint is web-only) | +| Fixtures | `conftest.py` fixtures | `tests/utils/` helper modules | +| CI unit gate | `12-check-unit-tests.yml` Python jobs | new Node job (proposed) | + +The headline: the TS runner has a formatter (via the global pre-commit) but no test runner, +no test gate, and no type gate. The Python side has all three. Closing that is the work. + +## 6. The cross-language contract is the seam that matters most + +`protocol.ts` is the single source of the `/run` types. `sdks/python/.../utils/wire.py` +hand-mirrors them. The contract is pinned by shared golden JSON +(`run_request.pi.json`, `run_request.claude.json`, `run_result.ok.json`, +`run_result.error.json`) and asserted by `test_wire_contract.py` on the Python side only. + +This is the highest-value place to add a TS test. A vitest test that loads those same +golden files and round-trips them through `protocol.ts` (parse the request shape, build a +result that matches the result fixture) means a contract change has to update both sides or +fail on both sides. It reuses fixtures that already exist, needs no harness and no network, +and directly protects the Python-to-Node boundary the whole feature rests on. + +## 7. Maintainability observations (not blockers) + +- **Architecture is sound.** Engines are peers behind one contract; tools are split by + concern; the responder seam was already extracted from `sandbox_agent.ts` (and is unit-tested). + `protocol.ts` carries thorough doc comments. A Python dev can navigate it. +- **Two large files.** `engines/sandbox_agent.ts` (1,085) and `tracing/otel.ts` (1,026) are the + obvious decomposition candidates. The responder extraction is the precedent: pull + cohesive seams out into separately testable units when you next touch them. Not a + big-bang refactor, and not a prerequisite for the test/CI work. +- **No `AGENTS.md` for the package.** The repo pushes area conventions into nested + `AGENTS.md` files (`web/AGENTS.md`, `api/AGENTS.md`) with a `CLAUDE.md` symlink. + `services/agent` has a strong `README.md` but no `AGENTS.md`, so the "where does runner + code/tests go, how do I run them" rules have nowhere to live. Adding one is cheap and + fits the repo's instruction-layering model. +- **Env-at-import-time.** Some modules read env on import (e.g. `skills.ts` reads + `AGENTA_AGENT_SKILLS_DIR`; the test sets it before a dynamic `import()`). vitest isolates + modules per test file, so this keeps working, but new tests touching such modules should + use dynamic import or `vi.resetModules()` rather than top-level import. + +## 8. One real decision to make + +**vitest vs `node:test`.** `node:test` is built in and adds zero dependencies, but it has +no first-class junit reporter or coverage UX and would diverge from the frontend. vitest +adds one dev dependency but matches `web/packages` exactly, gives junit + v8 coverage + +watch + filtering out of the box, and lets the CI wiring mirror the web job. Recommendation: +**vitest.** Everything in the plan assumes it; swapping to `node:test` would only change the +runner dependency and config, not the structure. diff --git a/docs/design/agent-workflows/projects/typescript-structure/status.md b/docs/design/agent-workflows/projects/typescript-structure/status.md new file mode 100644 index 0000000000..e9e0f85991 --- /dev/null +++ b/docs/design/agent-workflows/projects/typescript-structure/status.md @@ -0,0 +1,229 @@ +# Status + +Source of truth for this planning folder.

Locally the runner-tools commits sit at the bottom of the applied `nn` lane for `feat/agent-runner-engines`, which is why there is no separate applied GitButler lane for `feat/agent-runner-tools`. That is acceptable for the current stack as long as GitHub continues to show `#4778` based on `feat/agent-runner-tools`. + +### `#4782` / `feat/agenta-on-rivet` + +Keep only if it remains useful as an integration branch; otherwise rebuild or close later. + +This PR is based on `integration/agenta-rivet-base`, which is a merge-based bundle of the in-flight agent-workflows stacks. GitButler series need linear history, so this branch is deliberately off-workspace. The practical risk is drift: as the underlying SDK/service/runner/hosting/docs branches change, this integration branch must be manually refreshed. + +The branch also still uses the old `rivet` naming while the rest of the work is moving toward `sandbox-agent`. If it remains alive, it should eventually be rebuilt or renamed after the sandbox-agent rename lands. + +### `#4775` / `feat/agent-playground-ui` + +Reconcile before merging. + +Current GitHub metadata reports: + +| Field | Value | +|---|---| +| PR head | `592282099d8394d1e194e33550e6ec940d66d63f` | +| Commits | `7120276dd9` then `592282099d` | +| Base | `main` | + +Current `but status` reports the applied `pl` lane as: + +| Field | Value | +|---|---| +| Local displayed head | `7120276dd9` | +| Commit shown | `feat(frontend): agent config playground controls` | + +That means the remote PR has a review-fix commit that is not shown in the applied GitButler lane display.

Same logical + commits, different SHAs, but #4778 additionally has + `fix(agent): install python3 and rebuild the Pi extension` and the + `extension-tools.test.ts` + `Dockerfile.dev` work. The plural-named #4778 is the + one applied locally and the one we keep. Singular #4774 should be closed. + +2. **`docs/agent-workflows-design` (#4777) — DEPRECATED, close it.** + Superseded by `docs/agent-workflows` (#4779). #4779 contains everything in #4777 + plus the QA matrix, findings, and driver (28 extra files / +2921 lines). #4779 is + the applied lane. + +3. **`feat/agent-runner-tools` (#4773) — NOT deprecated, keep.** + It is the genuine base of the runner stack. Its two commits (`wire protocol`, + `tool bridge secrets`) sit at the bottom of the `nn` lane, which is why it is not + a separate lane. On GitHub the #4778 diff is computed from the merge-base, so the + #4773 → #4778 split is coherent. Minor wart: the "keep tool bridge secrets + runner-side" commit was re-created with a different SHA inside #4778, so it + appears in both branches' history (GitHub's 3-dot diff hides this). Harmless; + leave as is. + +4. **`feat/agenta-on-rivet` (#4782) + `integration/agenta-rivet-base` — NOT a + mistake, but fragile.** + `integration/agenta-rivet-base` is a **merge commit** that bundles the SDK, + service, runner, hosting, and docs stacks into one branch; `#4782` adds a single + harness commit (`run the Agenta harness on the rivet/ACP backend with forced + skills`) on top. It is not applied as a lane because GitButler cannot stack a + merge-based branch — this is the documented "series need linear history" gotcha. + So it is deliberately off-workspace, used as an integration/demo target. Two + concerns: (a) it still uses the old **rivet** naming while the rest of the work is + moving to **sandbox-agent**, and (b) it will drift as the underlying stacks change. + +No branch here is an accidental orphan. The only true deletions are the two +superseded duplicates (#4774, #4777). + +## Question 2 — Local work without an open PR + +- **Every applied lane already has a PR**, and every lane is pushed and in sync with + its origin branch. There is no committed-but-unpushed or committed-but-PR-less lane + inside the agent-workflows scope. +- The only "work without a PR" is the **uncommitted working-tree changes** (see Q3) — + they are not committed to any lane, so they have no PR by definition. +- There are also many unrelated local branches in the repo (e.g. `feat/agent-tools-wp7`, + `feat/agent-harness-port`, POC branches). Those are out of scope for this cleanup + and not part of the #4771–#4789 set. + +## Question 3 — Local changes not saved anywhere else (the real risk) + +There is substantial uncommitted work on `gitbutler/workspace` that is **not in any +branch, local or remote**: + +- **`rivet → sandbox_agent` code rename (working-tree only):** + - new: `sdks/python/agenta/sdk/agents/adapters/sandbox_agent.py` + - new: `services/agent/src/engines/sandbox_agent.ts` + - deleted: `rivet.py`, `rivet.ts` + No remote branch contains `sandbox_agent.py`. This is the missing other half of the + sandbox-agent rename: the `chore/sandbox-agent-*` branches (#4786–#4789) renamed the + deployment/runner surface but **left the engine + SDK adapter named `rivet`**. The + working tree finishes that rename and is uncommitted. + +- **New design-doc folders (working-tree only):** + `provider-model-auth/`, `skills-config/`, `model-config/`, `code-tool-sandbox/`, + `harness-capabilities/`, plus `feature-matrix-test.md`, `qa/cleanup-plan.md`, + `qa/implementation-plan.md`. None exist in any remote branch. + (`typescript-structure/` is the one exception — it also lives in + `chore/agent-runner-test-setup`, draft #4784.) + +- **Test relocation tail:** the 8 `services/agent/test/*.test.ts` deletions are the + cleanup half of the relocation to `services/agent/tests/unit/*` that #4786 (`cor`) + introduced. #4786 added the new layout but did not delete the old files; the working + tree deletes them. So this deletion belongs with the #4786 stack. + +- **Local-only husky hooks:** `.husky/post-checkout-user`, `.husky/pre-commit-user` + (plus edits to the tracked husky scripts and `.gitignore`). Likely local + developer-machine config, not feature work. + +- Plus broad edits across `sdks/python/agenta/sdk/agents/*`, `services/agent/src/*`, + `services/oss/src/agent/*`, and `web/oss/.../AgentChatSlice` — net **+1623/-2504** + across 77 tracked files. Because these overlap files already committed in the lanes, + they represent a **newer, diverged version** sitting on top of what the PRs contain. + +**Risk:** all of the above lives only in the working tree of one machine. A bad +`but` operation, a reset, or a worktree mishap loses it. It needs to be triaged into +lanes/branches and committed, or deliberately parked. + +## Recommended plan + +Do these in order. Steps 1–2 are safe and reversible; step 3 needs your decisions. + +### 1. Close the two duplicate PRs +- Close **#4774** (feat/agent-runner-engine) with a note pointing to #4778. +- Close **#4777** (docs/agent-workflows-design) with a note pointing to #4779. +- After closing, delete their remote branches (`feat/agent-runner-engine`, + `docs/agent-workflows-design`) and the local refs, so the rename stops being + ambiguous. + +### 2.

Corrections (verified against code): - The deployed service always runs over the sandbox-agent runner; the in-process Pi backend is test/reference only. - The sandbox-agent path supports the agenta harness too (pi, claude, agenta), and Pi system/append-system prompts are delivered on that path now. - Fix tool delivery facts: gateway and code tools are live on all paths, user mcp_servers is gated off and dead for Pi, the internal agenta-tools server is a tool-delivery vehicle for Claude, not user MCP. - Rewrite sessions to lead with current behavior (cold replay, no durable store) and separate the future session-store design. New living docs: - agent-configuration.md: the full config contract (FE form -> catalog type -> SDK interface -> runtime), what is enforced vs loose, wired vs decorative. - running-the-agent.md: how the agent service and sandbox-agent runner are run. Findings parked in scratch/ for review: dead-code report, model-auth correctness review, tools/MCP/capability investigation with a sandbox-removal plan and a capability-advertisement proposal, plus per-topic open-question notes.

The sidecar still has a `pi` +engine: a `/run` request with `backend: "pi"` runs Pi in-process inside the sidecar without +the daemon.

For the Claude-via-`claude-agent-sdk` path + this is *especially* clean: `allowedTools`/`disallowedTools`/`permissionMode` are native + options of that SDK, so the local Claude path enforces the tool plane in-process with no + runner at all. +- **Sandbox plane degrades the same way as local sidecar.** `LocalBackend` has no sandbox, so + it declares it cannot enforce `network`/fs isolation, and the same fail-loud rule fires. A + `LocalBackend` user who wants a true network boundary is told to use a sandboxed backend. + +So the SAME `capabilities` block is portable across all backends. What varies is only the set +of guarantees a backend can honor, and that variance is declared in one capability/enforcement +table, not discovered at runtime. + +## Port-shape change this forces (the one real structural cost) + +`Backend.create_sandbox()` currently takes **no arguments** (`interfaces.py:155`) and +`Environment._sandbox()` calls it parameterless. But network/fs isolation is a *per-config* +decision (set at Daytona create time), not a per-environment one. So either: + +- `create_sandbox(policy: SandboxPolicy)` gains a typed sandbox-policy argument threaded from + the config through `Environment.create_session` -> `_sandbox()` -> `create_sandbox`, or +- a `SandboxPolicy` is attached to the `Environment` at construction (cleaner if sandbox policy + is environment-scoped, worse if two configs in one environment want different network). + +I lean toward threading a `SandboxPolicy` through `create_sandbox`, because the capability is +authored per-agent-config, and one environment may serve several configs.

The capability descriptors the daemon reports +(`commandExecution`, `fileChanges`, `mcpTools`, `permissions`, ... in `AgentCapabilities`, +`sandbox-agent/dist/index.d.ts:30-49`) are **descriptive** (what the harness can do), not +**controls** (they do not turn anything off). The runner reads them only to branch tool +delivery, not to restrict the harness. + +## The backend dimension: Daytona vs local sidecar + +The harness toolset is identical across backends (same Pi, same Claude). What changes is the +**environment layer**: isolation, network reach, and what is installed to execute code. + +### Local sidecar (E2): the "sandbox" is the host + +The local provider spawns `sandbox-agent server` as a **child process on the sidecar host**, +inheriting `process.env` and binding `127.0.0.1` +(`sandbox-agent/dist/providers/local.js`, `provider.ts:42`). There is **no isolation**: + +- **Read/write** happen on the host filesystem, in a throwaway temp cwd + (`run-plan.ts:54-56`, cleaned up in the `finally`, `sandbox_agent.ts:296`). But `bash` is not + jailed to that cwd; the agent runs with the sidecar process's privileges and can read/write + what that user can. +- **Web/network** = whatever the host has. No allowlist, no block. If the sidecar can reach the + internet, so can the agent's `curl`. +- **Code execution** = whatever interpreters are installed in the sidecar image. (This is + exactly where F-006 bit: `python3` was missing from the image, so python code tools failed + with ENOENT until it was added.) +- There is **no per-run network or filesystem control knob** for local. The only lever is the + deny-all permission policy (Claude only). + +So local is fast and simple, but it trades away the sandbox. Treat E2 as "the agent runs +inside our sidecar," not "the agent runs in a sandbox." + +### Daytona (E3): a real isolated VM, with controls we do not yet use + +Daytona provisions a separate ephemeral sandbox per run +(`provider.ts:21-37`, `ephemeral: true`). Read/write/exec happen **inside that VM**, not on our +host. Code execution depends on what the snapshot bakes: our `agenta-sandbox-pi` snapshot is +`rivetdev/sandbox-agent:...-full` (daemon + Claude + CA certs) plus the `pi` CLI +(`sandbox-images/daytona/build_snapshot.py:42-73`), sized cpu=2/mem=4/disk=8. + +Crucially, **Daytona exposes network and resource controls that our runner does not surface.** +The provider passes a `create` overrides object straight to the Daytona SDK +(`provider.ts:26-37`, sandbox-agent `daytona({ create })`), and the SDK's create params include +(`@daytonaio/sdk/cjs/Daytona.d.ts:115-160`): + +- `networkBlockAll?: boolean` - block **all** network access for the sandbox. +- `networkAllowList?: string` - comma-separated **CIDR allowlist** (egress only to named + ranges). +- `resources` / `memory` / `disk` / `gpuType` - compute envelope. +- `volumes`, `autoStopInterval`, `user`, `language`, etc. + +Today `buildSandboxProvider` sets only `snapshot`/`image`/`target`/`envVars`/`ephemeral`. It +passes **no** network params, so a Daytona run has **full egress by default**. We *could* make +web access a real per-config control on Daytona by threading `networkBlockAll` / +`networkAllowList` into that `create` object. That lever exists at the backend and is unused. + +This is the sharp asymmetry: **Daytona can enforce "no web" or "web only to these hosts" at +the sandbox boundary; local cannot enforce anything** (it is the host). If "configurable web +access" is a product goal, Daytona is the backend that can deliver it cleanly, and the change +is in the runner's provider wiring, not in the harness. + +### The daemon's own primitives (a separate plane, not wired to the harness) + +Independently of the harness's tools, the sandbox-agent daemon exposes its own HTTP API over +the sandbox: `/v1/fs/*` (read, write, list, delete, move, upload), `/v1/process/*` (run a +command, stream logs), and `/v1/desktop/*` (full computer-use: mouse, keyboard, screenshot, +recording) (`sandbox-agent/dist/index.d.ts`). We use this control plane only for provisioning +(upload the extension, install pi, write AGENTS.md, run the usage readback). It is **not** +exposed to the model as tools. So "computer use" is available at the substrate but unused by +our agents today. Worth noting as a latent capability, not a current one. + +## Summary table + +| Question | `pi` (on sandbox-agent) | `claude` (on sandbox-agent) | +| --- | --- | --- | +| Read files (default) | yes (`read`) | yes (`Read`/`Glob`/`Grep`) | +| Write files (default) | yes (`write`/`edit`) | yes (`Write`/`Edit`) | +| Execute code (default) | yes (`bash`) | yes (`Bash`) | +| Web access (default) | only via `bash`+curl (no web tool) | yes (`WebFetch`+`WebSearch`) | +| Permission gating | none (Pi never gates) | yes; runner auto-approves | +| Selectively disable a tool | no interface today | no interface today | +| Block all tool exec | no (Pi ignores deny) | yes (`permissionPolicy: deny`) | +| Add tools (code/gateway/MCP) | yes (native) | yes (over MCP bridge) | + +| Backend | Isolation | Web by default | Web configurable? | Exec depends on | +| --- | --- | --- | --- | --- | +| Local sidecar (E2) | none (runs on host) | yes (host network) | no knob | sidecar image | +| Daytona (E3) | per-run ephemeral VM | yes (full egress) | **yes, but unused** (`networkBlockAll`/`networkAllowList` exist) | snapshot image | + +## Gaps and opportunities (if we want capabilities to be real controls) + +1. **No per-capability control exists on the sandbox-agent path.** "Disable web," "disable + exec," "read-only" are not configurable for either harness today. Adding them means wiring + the harness's own knobs: Pi's `--tools` / `--no-builtin-tools` (and actually honoring + `request.tools`, which the runner drops), and Claude's `allowedTools` / `disallowedTools` / + `permissionMode` on session creation. +2. **Web access is the cleanest thing to make configurable, via Daytona network params.** + `networkBlockAll` / `networkAllowList` are already accepted by the provider's `create` + object; the runner just needs to pass them from config. This gates web at the sandbox + boundary regardless of which tools the harness ships, so it works for both Pi (curl) and + Claude (WebFetch). +3. **Local cannot be made safe by config.** Because the local provider is the host, no + per-run network or filesystem confinement is possible there. If untrusted configs ever run, + they should run on Daytona, not local. +4. **Pi's missing web tool vs Claude's web tools** is a real product difference to surface: a + "give the agent web access" toggle means different things per harness (curl-in-bash for Pi, + first-class WebFetch/WebSearch for Claude). +5.

I cite the new files in the docs I own. + +## Open question: is `agenta` harness genuinely first-class on sandbox-agent, or pi-with-extras? + +The runner maps `harness: "agenta"` to `acpAgent = "pi"` and layers forced skills + prompt +extras (`run-plan.ts:78`). So on sandbox-agent, `agenta` is "pi ACP agent + Agenta forced +config", not a distinct ACP agent. I described it that way. Confirm this is the intended +long-term model (vs. a real `agenta` ACP agent) before the agent-template doc hardens it. + +## Open question: model override on sandbox-agent Pi + +QA F-007 says pi-acp accepts only `default` for the model category, so a real model id is +silently dropped on the Pi-over-sandbox-agent path. I documented this as a current gap in +architecture.md and ground-truth.md. I did NOT independently re-verify against pi-acp source +(it lives in the `sandbox-agent` npm package, not this repo). If you can confirm whether pi-acp +exposes any non-default model channel, that resolves whether F-007 is "wire it" or "fail loud". + +## Open question: sidecar.md vs folding into architecture.md + +I folded the sidecar story into `architecture.md` (sections "The Sidecar", "Licensing and +images", "Daytona sandbox") rather than creating `documentation/sidecar.md`. Reason: `README.md` +(not mine to edit) lists the doc reading order and has no `sidecar.md` entry; a new unreferenced +file would be a dangling doc. If you prefer a dedicated `sidecar.md`, move those three sections +out and add a README link. The content is self-contained enough to lift cleanly. + +## Open question: `LocalBackend` plan path + +`sdks/python/agenta/sdk/agents/adapters/local.py:16` points readers to +`docs/design/agent-workflows/scratch/sdk-local-backend/plan.md`. After the restructure that +content is at `docs/design/agent-workflows/archive/sdk-local-backend/` (and the active +workstream is `projects/sdk-local-tools/`).

If nothing matches, it logs and returns `undefined`, and **the harness + keeps its own default model** (`model.ts:67-69`). + +**Is there any provider concept? No.** The only place "provider" enters model routing is an +implicit harness->key-var guess in the runner: `harnessKeyVar = acpAgent === "claude" ? +"ANTHROPIC_API_KEY" : "OPENAI_API_KEY"` (`engines/sandbox_agent/run-plan.ts:91`). That guess +is used only to compute `hasApiKey` (whether to upload Pi's OAuth fallback), not to select +which key to inject. So a Pi run targeting a Gemini or Anthropic model still gets every key +dumped and relies on the harness to pick. + +Verdict: **correct enough for single-provider use, structurally wrong for routing.** The +model is "provider-blind." A model like `claude-opus-4-8` selected under the Pi harness has +no path that says "this needs the Anthropic key"; it works only because the Anthropic key is +in the dumped env anyway. + +--- + +## How credentials are resolved and injected (Q2) + +**Current reality: whole-vault dump.

The chosen + `model` is **never passed in and never consulted**. There is no model or provider filter. +- Dedup is "first wins": `env.setdefault(env_var, key)` (`secrets.py:140`).

No model/provider filter parameter exists. +- The values are **decrypted**: `VaultService.list_secrets` runs under + `set_data_encryption_key(...)` (`api/oss/src/core/secrets/services.py:52-59`) and the DTO + carries the plaintext `provider.key` (`api/oss/src/core/secrets/dtos.py:17-23`, + `StandardProviderSettingsDTO.key: str`).

For Daytona, the same map + is spread into the sandbox env vars (`engines/sandbox_agent/daytona.ts:33-39`, + `buildSandboxProvider` passes `plan.secrets` at `provider.ts:34`).

A compromised or prompt-injected harness, a +custom code-tool subprocess, or a misbehaving MCP server can read all of them. This is the +single most important current-correctness/security issue. Evidence: +`platform/secrets.py:132-141`, `sandbox_agent.ts:119`, `daytona.ts:33-39`, +`vault/router.py:130`. + +**One thing that IS correctly scoped:** code-tool and MCP env get only their **named** +secrets via `resolve_named_secrets` (`POST /secrets/resolve`, +`platform/secrets.py:29-78`), restricted to the requested set (`secrets.py:72-78`).

The fallback to the process + `AGENTA_API_KEY` (`connection.py:95-97`) is the standalone-SDK case (the env key is the + user's own). +- The backend enforces project scope from `request.state.project_id`, not from the body + (`vault/router.py:130-132`). EE adds an explicit `VIEW_SECRET` permission check + (`vault/router.py:103-115`). So a caller only ever reads their own project's vault. + +The `list_secrets` cache is keyed by `project_id` (`vault/router.py:117-139`), which is a +project-scoped cache, not a cross-user leak. + +**Caveat (runner-side, not backend-side):** the in-process Pi engine mutates +**process-global** `process.env` to inject keys, but it serializes runs and restores prior +env in a `finally` (`services/agent/src/engines/pi.ts:69-99`), so request A's vault keys do +not leak into request B. That is correct as written. The risk there is the inherited +baked-in dev key (see Q5, finding 3), not cross-request vault leakage. + +Verdict: **per-user/per-request auth is implemented correctly.** This is a current behavior +to PRESERVE. + +--- + +## Claude vs Pi auth differences (Q4) + +**Current reality: API-key first, OAuth/login fallback.

Vault keys are then overlaid + on top (`sandbox_agent.ts:119`). So Claude can authenticate via `ANTHROPIC_API_KEY` (vault + or baked) or a subscription token (`CLAUDE_CODE_OAUTH_TOKEN`/`ANTHROPIC_AUTH_TOKEN`) baked + into the sidecar. +- Pi auth: if no provider key is available for the harness's key var + (`hasApiKey = !!secrets[harnessKeyVar]`, `run-plan.ts:113`), the Daytona path uploads the + dev's local Pi OAuth login (`auth.json` + `settings.json`) into the sandbox + (`engines/sandbox_agent/daytona.ts:88-105`, `:127`). Local runs use the host's + `PI_CODING_AGENT_DIR` login (`daemon.ts:71-74`). +- **File-based auth that rotates:** the redesign's research is right that Pi/Claude rotate + their OAuth credential files. Today the code uploads a **snapshot** of `auth.json` + (`daytona.ts:90-101`). For a short-lived Daytona run this is fine, but it is a frozen + copy; it is never written back, and if the token has expired it is stale. This is a known + limitation, not a crash. Severity: LOW-MEDIUM (only the self-managed-OAuth-in-sandbox + case). + +Verdict: **functionally correct for API-key auth.** The OAuth-file-snapshot upload is the +weak spot the redesign's `source: runtime` / "never store the rotating file" addresses. + +--- + +## Concrete current-correctness risks (Q5), prioritized + +### R1 - Whole-vault provider-key dump (over-broad exposure).

Severity: MEDIUM-HIGH. +The model is a bare string with no provider. Nothing maps "model X needs provider Y's key." +It works only because R1 dumps every key. Selecting a non-default-provider model under a +harness has no first-class routing; it depends on the harness's own resolution plus the +dumped env. +Evidence: `AgentConfig.model: Optional[str]` (`dtos.py:323`); the only provider inference is +the harness-name guess `run-plan.ts:91`; `applyModel` is a post-hoc `setModel` with a string +suffix match (`model.ts:7-16`, `:46-70`). +Fix in redesign: `ModelSpec { provider, model, params }` committed in the config; provider is +first-class and the resolver matches account provider to model provider. + +### R3 - Inherited provider env is not cleared before applying the plan. Severity: MEDIUM. +On the sandbox-agent path the daemon env starts with the sidecar's baked provider keys +(`daemon.ts:78-88`), and vault keys are overlaid (`sandbox_agent.ts:119`). A baked dev key +for a provider the vault does NOT have stays visible to the run. There is no clear-then-apply +step on this path. (The in-process Pi engine DOES restore/delete per run at `pi.ts:80-92`, +but only for the keys present in `secrets`; a baked key absent from `secrets` is untouched.) +Evidence: `daemon.ts:78-88`, `sandbox_agent.ts:119`, contrast `pi.ts:69-99`. +Fix in redesign: security non-negotiable #5, "clear inherited provider env before applying." + +### R4 - Duplicate keys for one provider: first silently wins (no forced choice). Severity: LOW-MEDIUM. +`env.setdefault(env_var, key)` means a project with two OpenAI keys silently uses the first +encountered. The completion path does the opposite (last wins, +`sdks/python/agenta/sdk/managers/secrets.py` provider loop), so the two paths disagree. +Evidence: `platform/secrets.py:140`. +Fix in redesign: multi-account by slug; error (do not guess) when multiple accounts and no +default/binding. + +### R5 - Silent model fallback can mislead (degraded, not data-incorrect). Severity: LOW. +When `setModel` cannot honor the requested model, the run proceeds on the harness's default +model. This is intentional and is handled honestly for tracing: `applyModel` returns +`undefined` and the chat span is labelled generically rather than claiming the requested +model (`sandbox_agent.ts:202-205`, `:209`; `model.ts:67-69`). So it is NOT a silent +mislabel. But the user still gets a different model than asked, with only a stderr log +(`model.ts:67`). Not surfaced to the caller. This is a UX/observability gap, not a +correctness bug. Note: this is the opposite of "silently-dropped model override claimed as +applied"; the code is careful here. + +### R6 - `AGENTA_CRYPT_KEY` defaults to `"replace-me"`. Severity: HIGH if shipped, but PRE-EXISTING / OUT OF SCOPE. +`api/oss/src/utils/env.py:410`. The vault data-encryption key has a weak default. Not +introduced by the agent feature; flagged by the redesign too (security non-negotiable #8). +Call out for a separate security follow-up. + +--- + +## What is already CORRECT and should be preserved + +- **Per-request, per-user authorization** (Q3). Lazy, never cached, request-scoped context, + project scope from `request.state`, EE permission check. `connection.py:108-133`, + `propagation.py:74/94`, `vault/router.py:103-132`. +- **Named tool/MCP secret resolution is already least-privilege** (only requested names, + restricted to the requested set). `platform/secrets.py:29-78`.

Preserve this. +- **In-process Pi env restore discipline**: serialized runs + `finally` restore prevent + cross-request vault-key leakage. `pi.ts:69-99`. The redesign should keep this and extend + it to clear-then-apply. +- **Best-effort optionality**: an empty vault is valid (the harness falls back to its own + login); a vault outage returns empty rather than failing the run. + `platform/secrets.py:109-130`. Keep this for the self-managed (`source: runtime`) case. +- **The three-way split already exists in the ports** (agent identity / harness config / + runtime). `RunSelection` is deliberately not part of the neutral `AgentConfig` + (`dtos.py:364-387`).

Marks: VERIFIED (read the code), STALE (memory hint +that no longer holds), DEAD (code exists but nothing reaches it). + +## TL;DR verdict + +- **Builtin tools**: live. Pi-only. A bare name added to the session allowlist. +- **Gateway (callback) tools**: live on every path (in-process Pi, Pi-over-ACP, Claude-over-MCP, + local + Daytona). This is the real, exercised tool path. +- **Code tools**: live and reachable. `python3` IS in the prod image now (the old ENOENT is + fixed). Caveat: the child env is a tight allowlist, so a code tool that imports a third-party + package will fail (no pip/venv, no inherited env). +- **Client tools**: plumbed end to end on the runner side (throws in-sandbox, emitted as + `interaction_request`), but full browser fulfillment is a frontend-egress concern, not + verified here as working UI. +- **User MCP servers** (`mcp_servers` config): effectively dead on the deployed path. + Gated OFF by `AGENTA_AGENT_ENABLE_MCP` (default false) at the service, AND gated off for Pi + in the runner. So today it reaches nobody by default, and even with the flag on it reaches + Claude only. Pi/agenta is the default harness, so in practice user MCP is dead. +- **Sandbox-side MCP machinery** (`mcp-server.ts` + the `agenta-tools` synthetic server in + `mcp-bridge.ts`): only used to deliver GATEWAY/CODE tools to a non-Pi (Claude) harness that + reports `mcpTools`. It is NOT used for user `mcp_servers`. It is reachable only on the Claude + path. On the default Pi path it is never launched. +- **Capability advertisement**: `HarnessCapabilities` exists in the wire, is probed in the + runner, gates tool delivery internally, and is returned on the `/run` result. But it is a + DEAD read on the consume side: parsed into `AgentResult.capabilities` (`dtos.py:297`, + `wire.py:87`) and then never read by the service, `/inspect`, or the frontend. `/health` + advertises `engines`/`harnesses` but NOT capabilities. + +## End-to-end trace (deployed = sandbox-agent path) + +Config -> service resolution -> wire -> runner -> harness. + +### 1. Config (SDK) + +`AgentConfig.tools` is a list of 4 discriminated configs: `builtin` / `gateway` / `code` / +`client` (`sdks/python/agenta/sdk/agents/tools/models.py:22-77`). `AgentConfig.mcp_servers` +is a SIBLING field, not a tool type (`sdks/python/agenta/sdk/agents/mcp/models.py`). + +Three orthogonal axes per tool: `type`/`kind` (executor), `needs_approval`, `render` +(`models.py:22-29` ToolConfigBase; `protocol.ts:52-76`). + +"4 executors" = `builtin` (a name, not a spec) + 3 spec kinds: `callback` / `code` / `client` +(`models.py:131-153`). NOTE: the resolved `kind` for a gateway tool is **`callback`**, not +`gateway`. There is no `gateway` kind on the wire. The config `type` `gateway` -> resolved +`kind` `callback` (`resolver.py:162-167`, `models.py:131-137`). + +### 2. Service resolution + +`services/oss/src/agent/app.py:78-80`: +``` +resolved_tools = await resolve_tools(agent_config.tools) +resolved_mcp = await resolve_mcp_servers(agent_config.mcp_servers) +``` +Both are thin re-exports of SDK platform entrypoints. The service files are now shims: +- `services/oss/src/agent/tools/resolver.py` re-exports `resolve_tools` and adds the MCP gate. +- `gateway.py`, `secrets.py`, `__init__.py` are re-export shims to + `agenta.sdk.agents.platform.*`. + +Real resolution: `sdks/python/agenta/sdk/agents/platform/resolve.py:40-65` -> +`ToolResolver.resolve` (`sdks/python/agenta/sdk/agents/tools/resolver.py:102-177`). + +Per type: +- `builtin` -> name lands in `builtin_names`, no network (`resolver.py:103-107`). +- `code` -> declared `secrets` resolved by name via the named-secret provider, injected into + spec `env` (`resolver.py:124-154`). Script not run here. +- `client` -> pass-through to `ClientToolSpec` (`resolver.py:156-159`). +- `gateway` -> `AgentaGatewayToolResolver` posts to API `/tools/resolve`, gets a `call_ref` + slug, wraps in `CallbackToolSpec` + one `ToolCallback` -> `/tools/call` + (`resolver.py:161-167`; gateway impl now in `platform/gateway.py`). + +MCP gate (THE key gate): `services/oss/src/agent/tools/resolver.py:22-37`. If +`AGENTA_AGENT_ENABLE_MCP` not truthy -> returns `[]`. Default off. So `resolved_mcp` is empty +by default and `mcpServers` is omitted from the wire. + +### 3. Wire + +`request_to_wire` -> `mcpServers` only when non-empty (`utils/wire.py:54-56`, gated by +`config.wire_mcp()`). `customTools` = resolved specs, `toolCallback` = the callback, +`tools` = builtin names. Wire contract: `protocol.ts` (TS) mirrored by `utils/wire.py`. + +### 4. Runner delivery (the fork) + +Engine selected by `server.ts:38-49`: default `sandbox-agent`, request `backend:"pi"` picks +the in-process engine. Deployed = `sandbox-agent` (`runSandboxAgent`). + +Delivery decision in `engines/sandbox_agent/mcp.ts:50-75` (`buildSessionMcpServers`): +- If `isPi` OR `!capabilities.mcpTools` -> return `[]` (no MCP servers attached). For Pi this + means NO MCP at all (neither agenta-tools nor user servers). Tools for Pi are delivered the + Pi-native way via the extension, NOT through this function. +- Else (Claude, `mcpTools` true) -> attach `buildToolMcpServers(...)` (the synthetic + `agenta-tools` server carrying gateway/code specs) + `toAcpMcpServers(userMcpServers)`. + +So: +- **Pi-native delivery**: the bundled extension (`extensions/agenta.ts:38-75`) reads + `AGENTA_TOOL_PUBLIC_SPECS` + `AGENTA_TOOL_RELAY_DIR` and calls `pi.registerTool` per spec. + Execution goes through `runResolvedTool` (`tools/dispatch.ts:104`) -> relay file -> + runner-side `startToolRelay` (`tools/relay.ts:121`) -> `/tools/call` (gateway) or local + `python3`/`node` (code). The extension env carries PUBLIC metadata only; private specs/auth + stay in runner memory (`pi-assets.ts:31-50`). +- **Claude MCP delivery**: `mcp-bridge.ts:63` builds the `agenta-tools` ACP stdio server; + `mcp-server.ts` is the bridge process; it relays calls back via `runResolvedTool` with a + `relayDir`. User `mcp_servers` (if the flag were on) would be ADDITIONAL ACP stdio servers + via `toAcpMcpServers` (`mcp.ts:15-36`), but pi-acp does not forward those and they are + gated off for Pi. + +### 5. In-process engine (reference only) + +`engines/pi.ts:150-198` (`buildCustomTools`) branches on kind directly: code -> local +subprocess, callback -> `/tools/call`, client -> skipped. Ignores `request.mcpServers` +ENTIRELY (`PI_CAPABILITIES.mcpTools = false`, `pi.ts:60`). Not the deployed path. + +## What is live / gated / dead, with evidence + +| Thing | State | Evidence | +| --- | --- | --- | +| Builtin tools (Pi) | LIVE | `resolver.py:103-107`; allowlist `pi.ts:280-283` | +| Gateway/callback tools | LIVE all paths | `callback.ts:32`; relay `relay.ts:103-112`; Pi ext `agenta.ts:60-71` | +| Code tools | LIVE; `python3` in image | `code.ts:115`; `Dockerfile:27` installs `python3` | +| Client tools | PLUMBED (runner); FE unverified | throws `dispatch.ts:112-115`; filtered `mcp-server.ts:63`, `public-spec.ts:17` | +| User `mcp_servers` | GATED OFF (default) + Pi-dead | service gate `resolver.py:22-37`; runner gate `mcp.ts:61` | +| `agenta-tools` synthetic MCP server | LIVE only on Claude path | `mcp-bridge.ts:63`, `mcp-server.ts`; never built for Pi `mcp.ts:61` | +| `HarnessCapabilities` probe | LIVE in runner, gates delivery | `capabilities.ts:42-52`, used `sandbox_agent.ts:183-193` | +| `result.capabilities` consume | DEAD | parsed `wire.py:87`/`dtos.py:297`, read by nobody downstream | +| `needs_approval` | Claude-only honored | responder `responder.ts`; Pi no-op | +| `render` | runner copies hint; FE projection partial | `protocol.ts:133-136`, copied onto events | + +## STALE memory hints, corrected + +- "missing python3 in the agent image (python code tools ENOENT)" -> STALE/FIXED. The prod + Dockerfile installs `python3` (`services/agent/docker/Dockerfile:26-28`) with a comment that + names exactly this failure mode. Code tools with `runtime: python` work in the prod image. + (Caveat below: only the interpreter, no third-party packages.) +- "stale Pi extension bundle (custom tools silently undelivered on rivet)" -> partially + current as a CLASS of risk. The extension is a baked esbuild bundle + (`pi-assets.ts:24-25`, `Dockerfile:48`). If the image is built without `build:extension`, + or `SANDBOX_AGENT_EXTENSION_BUNDLE` points at a stale file, tools silently do not register + (`installPiExtensionLocal` logs and returns, `pi-assets.ts:53-65`). The prod Dockerfile does + run `build:extension`, so the prod image is fine; the risk is dev/compose images that + override CMD or skip the build step. This is a build-hygiene risk, not a code bug. +- "MCP gated behind AGENTA_AGENT_ENABLE_MCP, claude-only" -> VERIFIED, still true. + +## Real, current gaps and oddities (the "does not make sense" list) + +1. **User MCP is dead by default and Pi-impossible.** `AGENTA_AGENT_ENABLE_MCP` defaults off. + Even on, `buildSessionMcpServers` drops user MCP for Pi (`mcp.ts:61`), and Pi is the default + harness. So the entire `mcp_servers` config field is a silent no-op for the common case. The + field is accepted, serialized only when the flag is on, then dropped at the runner. This is + the silent-drop F-009 the harness-capabilities project is about. + +2. **Two MCP machineries that do different things share the word "MCP".** (a) The synthetic + `agenta-tools` server (`mcp-bridge.ts` + `mcp-server.ts`) is an internal TOOL DELIVERY + vehicle for Claude - it has nothing to do with user-declared MCP. (b) `toAcpMcpServers` + delivers user `mcp_servers`. Both live under "MCP" and both are off on the default path. + This conflation is most of the confusion. + +3. **`HarnessCapabilities` is half a feature.** The runner probes it and gates on it, which is + good, but the probe almost always falls back to the STATIC per-harness guess + (`capabilities.ts:24-39`) because `sandbox.getAgent(...).capabilities` is usually absent. And + the result it returns is read by nobody. So we pay for a probe whose only real effect is the + internal `mcpTools` branch, which a static `harness === "pi"` check would do identically. + +4. **Code tools cannot import packages.** `buildChildEnv` (`code.ts:99-108`) gives the child + only PATH/HOME/locale/temp + the tool's own secrets. The image has `python3` and `node` but + no `pip install`/`npm install` of arbitrary deps at tool time, and no `NODE_PATH` to the + runner's `node_modules`. So a code tool is limited to the stdlib. Fine for glue, surprising + for anything real. Worth documenting as a constraint, not necessarily removing. + +## Removal proposal: take user-MCP out of the sandbox + +User said: "the way we implement it does not make sense; remove it at least from the sandbox." +Reading: remove the user-declared MCP plumbing from the sandbox-agent runner (NOT the +gateway/code tool delivery, which happens to also use an MCP server for Claude). Below is a +precise, code-free plan (other sessions own the code; this is a plan). + +### What is safe to remove (sandbox/runner side) + +The user-MCP path is small and isolated: + +- `services/agent/src/engines/sandbox_agent/mcp.ts`: `toAcpMcpServers` (the user-MCP -> ACP + stdio converter) and its call inside `buildSessionMcpServers` (the `...toAcpMcpServers(...)` + spread, `mcp.ts:73`). Keep `buildToolMcpServers` (that is the Claude tool-delivery vehicle). +- The `userMcpServers` parameter threaded into `buildSessionMcpServers` + (`sandbox_agent.ts:189`, `mcp.ts:43,60,62`). +- `McpServerConfig` on the wire (`protocol.ts:89-97`) and `mcpServers` on `AgentRunRequest` + (`protocol.ts:227`) - ONLY if we also drop the field service-side; otherwise leave the wire + field but stop consuming it. + +### What depends on it / what breaks + +- Nothing in the deployed path breaks, because it is already gated off + (`AGENTA_AGENT_ENABLE_MCP` default false). Removing it changes behavior only for someone who + set the flag AND used Claude AND declared `mcp_servers`. That is a near-empty set. +- The golden wire-contract fixtures pin `mcpServers` (`services/agent/CLAUDE.md` wire rules). + Removing the field means updating `protocol.ts` + `utils/wire.py` + both golden fixtures + + both contract tests, deliberately, together. This is the only real cost. +- `toAcpMcpServers` is re-exported (`sandbox_agent.ts:75`) and has unit tests; those go too. + +### Recommended shape (simplest honest end state) + +Two clean options. Prefer **A** if we want to keep the door open, **B** if we want it gone. + +**Option A - keep the field, stop pretending it works on the default path; make the drop loud.** +Leave `mcp_servers` in config and on the wire, but: +- Delete `toAcpMcpServers` user-MCP delivery from the runner (it only ever reached Claude, off + by default). +- Make the SERVICE reject a non-empty `mcp_servers` for a harness that cannot honor it (fail + loud, per the harness-capabilities proposal slice 1), instead of silently dropping at the + runner. This is the smallest change that removes the silent no-op. +- Result: the sandbox no longer carries user-MCP code; the boundary tells the user "this + harness does not support MCP" up front. + +**Option B - remove user MCP entirely (config + wire + runner).** +- Drop `AgentConfig.mcp_servers`, the `MCPResolver`, `resolve_mcp_servers`, + `AGENTA_AGENT_ENABLE_MCP`, the `mcpServers` wire field, `toAcpMcpServers`, and the + `agenta.sdk.agents.mcp` package's user-server half. +- Keep `buildToolMcpServers`/`mcp-server.ts` (Claude tool delivery) untouched - it is not user + MCP. +- Update the golden wire fixtures + contract tests in the same change. +- Result: the only "MCP" left in the tree is the internal Claude tool-delivery server, which + could even be renamed away from "MCP" (e.g. `tool-bridge`) to kill the conflation. + +### What NOT to remove + +- `mcp-server.ts` / `mcp-bridge.ts` `buildToolMcpServers` / the relay: these deliver GATEWAY + and CODE tools to Claude. Removing them breaks tools on the Claude harness. They are + mislabeled (they are a tool bridge that happens to speak MCP), not dead. +- The Pi extension tool path: that is the main tool delivery for the default harness. + +### My recommendation + +Option A now (cheap, removes the silent failure, shrinks the sandbox), Option B later if the +product decides user-MCP is not a near-term feature. If Part 1 of the harness-capabilities +proposal (MCP on Pi via the extension) is actually wanted, that is the OPPOSITE of removal and +the two should not both be in flight - decide first. + +## Capability advertisement proposal + +### Current state (verified) + +- `/health` returns `{ status, runner, protocol, engines, harnesses }` + (`version.ts:27-35`). No capabilities. `HARNESSES = ["pi","claude","agenta"]` is a flat list. +- `HarnessCapabilities` is probed per RUN inside the runner (`capabilities.ts`), used only to + gate tool delivery (`sandbox_agent.ts:183`), and returned on the result. The probe is mostly + the static fallback because the daemon rarely fills `info.capabilities`. +- The consume side is dead: `AgentResult.capabilities` is parsed and dropped. No `/inspect` + surface, no FE gate, no service gate. +- There is a substantial design already: `projects/harness-capabilities/proposal.md` argues for + a static per-harness capability table in `sdks/python/agenta/sdk/agents/capabilities.py`, with + the runtime probe as a narrowing Layer 2, surfaced via `/inspect` as a `harness_capabilities` + map, and a fail-loud backend reject. `capability-map.md` documents the actual web/exec/read/ + write matrix per harness x sandbox. + +### What the runner SHOULD advertise (and how) + +Two grains, both worth having: + +1. **Static, run-independent, on `/health`** (the version-skew sibling). Extend `runnerInfo()` + so `harnesses` is not a flat list but a map: per harness, the static capability set the + runner believes it can drive (`mcpTools`, `permissions`, `images`, `planMode`, plus a + `toolDelivery` tag: `pi_native` | `acp_mcp`). This is the "what MAY run" contract a schema + and a form can read before any run. It is the runner half of the harness-capabilities + static table; pin it against the SDK table with a golden contract test (same discipline as + the wire contract). + +2. **Dynamic, per-run, on the `/run` result** (already exists as `capabilities`). Keep it, but + make it CONSUMED: the service should (a) compare probed vs static and log drift, (b) + optionally fold a small subset into the `/invoke` response or a span attribute so the + product can see what actually ran. Today this field is wasted. + +### How the service consumes it + +- At schema/`inspect` time: read the static map (from the SDK table, mirrored from `/health`) + and emit a `harness_capabilities` document so the FE can show/hide `mcp_servers`, + `permission_policy`, and gate `model`. This is proposal Part 2 slice 2. +- At invoke time (fail loud): before starting the runner, reject a non-empty config field the + selected harness cannot honor (`mcp_servers` on pi/agenta; an unsettable `model`). This is + proposal Part 2 slice 1 and the single highest-value change - it converts the silent drop + into an honest error. It does not need the runner change to land; the SDK static table is + enough. +- At result time: intersection check. If the probe reports LESS than the static table for a + capability the user asked for, fail or warn loudly; if MORE, log drift. + +### Minimal first step + +Land the SDK static capability table + the backend fail-loud reject (proposal slice 1). It +needs no runner change, kills the worst silent failures (user MCP on Pi, model on sandbox-agent), +and gives the FE something to read. The `/health` capability map and the consume-the-probe work +are good follow-ups but not the bottleneck. + +## Open questions (for the user) + +1. Is user-declared `mcp_servers` a real near-term product feature, or scratch? If scratch, + Option B (remove entirely) is cleanest. If real, the right move is the harness-capabilities + Part 1 (MCP on Pi via extension), which is the opposite of removal. These conflict - pick one. +2. Should the internal Claude tool-delivery server keep the name "MCP"? Renaming it (e.g. + `tool-bridge`) would end the conflation that makes all of this confusing. It speaks MCP on + the wire to the harness, but it is an Agenta tool relay, not a user MCP server. +3. Do we want `result.capabilities` consumed at all, or should it be removed too? It is dead + today. Either wire it into `/inspect`/the FE (per the proposal) or drop it from the result. +4. Code tools are stdlib-only (no package install). Is that the intended contract, or do we + want a provisioning story (a base image with common libs, or a per-tool deps manifest)? +5. The capability probe is mostly the static fallback. Is it worth keeping the probe at all + before the daemon actually fills `info.capabilities`, or should we ship the static table now + and add the probe when there is real data to probe? + + From

From dce299c3191effa2ac0618f364e697c60ef91857 Mon Sep 17 00:00:00 2001 From: Mahmoud Mabrouk Date: Tue, 23 Jun 2026 17:10:46 +0200 Subject: [PATCH 4/9] chore(agent): remove dead code from agent-workflows Act on the dead-code report review. Remove zero-caller and broken code, and demote the confusing in-process POC backend out of the shipped SDK. Deleted (zero callers / unimportable): - services/oss/src/agent/client.py (logic moved to the SDK platform package) - sdks: agents/ui_messages.py (Vercel-adapter shim, not the internal IR), agents/tools/wire.py (superseded by ToolSpec.to_wire()), parse_tool_configs, engines/running/registry.py (broken import since the 2026-05 SDK reorg), engines/running/sandbox.py::is_import_safe - services/agent/src/tracing/otel.ts::shutdownTracing (no process-exit path) InProcessPiBackend was a public 'reference backend' that the service never selects. Removed it from the SDK public API and moved the class to a test-only helper so the transport round-trip integration test still runs. Updated the design docs to match. Kept on review: the sandbox_agent.ts test re-exports, LocalBackend, the Claude and Agenta harnesses, and the service secret/gateway re-export shims (deletable later once their tests repoint to agenta.sdk.agents.platform). Tests green: SDK agents 158 unit + 3 transport integration, service agent 20 unit, runner 104 vitest. ruff and tsc clean.

The root cause is in +`research.md`: Pi only exposes a provider's models once it can see a credential for that +provider, and the ACP per-run agent dir does not give Pi that credential in a form its model +registry counts. So Pi reports no matching models, pi-acp offers only `default`, and +`applyModel` swallows the rejection. + +The proposal has three parts: + +1. Configure Pi correctly on the ACP path so a requested model is actually settable. +2. Fail loud, never silent, when a model still cannot be set. +3. Expose the valid model choices in the inspectable schema, per harness. + +Parts 1 and 2 are the fix. Part 3 makes the choices discoverable so callers and the +frontend stop guessing. + +## Part 1: configure Pi correctly on the ACP path + +### Goal + +Give Pi a credential it recognizes for the requested model's provider, inside the per-run +agent dir the runner already controls, so `get_available_models` returns that provider's +models and pi-acp surfaces them as real `provider/id` options. Then `applyModel` finds a +match and `setModel` succeeds. + +### What to write, and where + +The runner already creates a throwaway per-run agent dir and points the daemon at it via +`PI_CODING_AGENT_DIR` (`prepareLocalAgentDir`, `sandbox_agent.ts:287-302`; the sibling +SYSTEM.md/APPEND_SYSTEM.md fix writes into the same dir). That dir is exactly where Pi reads +`auth.json` and `models.json` (`config.js:404-422`). Write the provider credentials there in +the form Pi's registry counts as configured auth. + +Two complementary writes, both into the per-run agent dir: + +1. **`auth.json` from the resolved vault keys.** For each resolved provider key, write the + `auth.json` entry Pi expects: + + ```json + { + "openai": { "type": "api_key", "key": "$OPENAI_API_KEY" }, + "anthropic": { "type": "api_key", "key": "$ANTHROPIC_API_KEY" } + } + ``` + + Pi resolves `"$OPENAI_API_KEY"` from the daemon env at request time + (`docs/providers.md:107-127`), so the secret value itself never lands on disk: the runner + already passes the key as launch env (`buildDaemonEnv`, `sandbox_agent.ts:380-391`), and the + `auth.json` entry just tells Pi which providers are configured. This makes + `authStorage.hasAuth(provider)` true for each keyed provider, so `getAvailable()` includes + that provider's built-in models. Merge with the login's existing `auth.json` (OAuth) that + `prepareLocalAgentDir` already copies, so subscription auth still works. + + Writing `auth.json` (not relying on env alone) is the robust choice: `auth.json` takes + priority over env (`docs/providers.md:105`), it is the channel Pi's headless RPC path + reads most reliably, and it keeps the credential channel identical to the in-process path + in intent. + +2. **`models.json` only when the requested model is not a built-in.** For a standard + provider (OpenAI, Anthropic, ...) a built-in model id is enough once `auth.json` marks the + provider configured: Pi already knows the model. Write `models.json` only to (a) point a + built-in provider at a proxy `baseUrl`, or (b) register a genuinely custom model + (Ollama/vLLM/gateway). Format per `docs/models.md:132-192`: + + ```json + { + "providers": { + "openrouter": { + "baseUrl": "https://openrouter.ai/api/v1", + "api": "openai-completions", + "apiKey": "$OPENROUTER_API_KEY", + "models": [{ "id": "anthropic/claude-3.5-sonnet" }] + } + } + } + ``` + + This keeps the common case (a built-in OpenAI/Anthropic id) to a single `auth.json` write + and reserves `models.json` for the custom case. + +### Daytona parity + +The Daytona path uploads the agent dir through the sandbox FS API +(`uploadPiAuthToSandbox`, `uploadSystemPromptToSandbox`, `sandbox_agent.ts:223-253`, +`679-696`). Add an `auth.json`/`models.json` uploader the same way, into `DAYTONA_PI_DIR`, +so the remote Pi sees the same configured providers. The provider keys already flow to the +sandbox env via `daytonaEnvVars` (`sandbox_agent.ts:582-597`), so `"$OPENAI_API_KEY"` interpolation +resolves there too. + +### Create the per-run agent dir for a model override, not only for skills + +Today the local Pi path only creates a per-run agent dir (and points +`PI_CODING_AGENT_DIR` at it) when forced skills or a system prompt exist +(`sandbox_agent.ts:916-929`: `if (skillDirs.length > 0 || hasSystemPrompt)`). A plain `model` +override takes the `else` branch and leaves the shared login dir in place. So the Part 1 +write has to make "a model/provider config is needed" a third reason to create and point at +the per-run dir, or the fix never runs for the exact failing case (a model override with no +skills and no system prompt). Extend that condition to include "the run carries resolved +provider secrets" (or always, for Pi local), and write `auth.json` into the per-run dir +there. Without this the auth.json write lands nowhere the daemon reads. + +### Fix the secret env-var name mismatch (one-line, separate from the agent dir) + +Independent of the agent-dir writes, the Python secret resolver maps one provider to the +wrong env var: `secrets.py:33` emits `TOGETHERAI_API_KEY` for `together_ai`, but Pi reads +`TOGETHER_API_KEY` (`pi-ai env-api-keys.js:117`). So a Together vault key never unlocks +Together models on either path. Fix the mapping to `TOGETHER_API_KEY`. This belongs in the +Python resolver (it owns the vault-kind to env-var map), and it is the one Part 1 change that +is correctly placed in Python rather than the runner. Audit the rest of `_PROVIDER_ENV_VARS` +against Pi's `getApiKeyEnvVars` while here. + +### Provider-id caveat: openai vs openai-codex + +Pi's Codex models live under the `openai-codex` provider (OAuth, the ChatGPT/Codex login), +while a vault `OPENAI_API_KEY` maps to the `openai` provider (`getApiKeyEnvVars`: +`openai -> OPENAI_API_KEY`). So writing an `openai` `auth.json` entry unlocks the `openai` +provider's `gpt-*` ids (for example `openai/gpt-5.5`), not `openai-codex/gpt-5.5`. The +default Pi login on the runner is often the Codex OAuth, whose ids are `openai-codex/...`. +The fix must therefore (a) write the `openai` entry from the vault key so `openai/gpt-5.5` +becomes settable, and (b) keep the requested model id provider-agnostic in matching: the +existing `pickModel` suffix match (`sandbox_agent.ts:513-522`) already resolves a bare `gpt-5.5` +against either `openai/gpt-5.5` or `openai-codex/gpt-5.5`, so a caller passing `gpt-5.5` +lands on whichever provider is authed. Document that a fully provider-qualified id +(`openai-codex/...`) only works when that provider's auth is present. + +### Why this is the core fix + +It removes the cause, not the symptom. Once Pi can see the credential for the requested +model's provider, `getAvailable()` returns that provider's models, pi-acp surfaces them as +`provider/id` options, the sandbox-agent daemon's `model` category carries them, and +`applyModel(session, "gpt-5.5")` matches `openai/gpt-5.5` (the existing `pickModel` suffix +match at `sandbox_agent.ts:513-522` already handles the `provider/` prefix). No silent fallback, +because the value is genuinely settable. + +### Tests + +- Unit: given resolved secrets `{OPENAI_API_KEY: ...}`, `prepareLocalAgentDir` writes an + `auth.json` with an `openai` entry whose key is `"$OPENAI_API_KEY"`, merged with any copied + login `auth.json`. Never writes a raw secret value. +- Integration (httpx-mocked resolvers, fake runner): a run with `model: "gpt-5.5"` and an + OpenAI key resolves `model` to `openai/gpt-5.5`, not `undefined`. +- Live acceptance (llm_required): the F-007 repro on sandbox-agent local with a real OpenAI key now + applies the requested model (assert via the "not settable" log absence and the returned + `model` field). + +## Part 2: fail loud, never silent + +After Part 1, a requested model can still be genuinely unsettable: the provider has no key, +the model id is wrong, or the harness (for example Claude Code over ACP) only accepts its own +aliases. Today `applyModel` logs and returns `undefined`, and the run proceeds on the harness +default. That is the cost trap. Make it an error the caller sees. + +### sandbox-agent path + +Change `applyModel` (`sandbox_agent.ts:555-575`) to distinguish two outcomes: + +- A model was requested and resolved to a settable value -> return it. +- A model was requested and cannot be set after the retry -> raise a typed error + (`ModelNotSettableError`) carrying the requested model and the allowed values parsed from + the daemon error (`allowedFromError`, `sandbox_agent.ts:538-546`). + +Fix the allowed-set enumeration while here. `allowedModels(session)` +(`sandbox_agent.ts:524-536`) maps each option to `c.id`, but pi-acp builds the model option's +entries as `{ value: model.modelId, name, description }` and sandbox-agent reads +`entry.value` (`extractConfigValues`). So `allowedModels()` returns `[]` today, and the +fallback enumeration in `applyModel` is blind: only `allowedFromError()` (parsing the daemon +error string) currently surfaces the allowed set. Change `allowedModels` to read +`c.value ?? c.id` so the error message and any pre-validation have the real list. + +`runSandboxAgent`'s catch already turns thrown errors into one clear caller line via `conciseError` +(`sandbox_agent.ts:763-775`, `1136-1139`). Add a branch so the message reads, for example: + +``` +pi: model 'gpt-4o-mini' is not available on this run. The OpenAI provider has no key in the +project vault, or the model id is unknown. Available: openai/gpt-5.5, openai/gpt-5.5-codex. +``` + +Gate the strictness so an empty/absent request still uses the harness default (no model +requested is not an error). Only a requested-but-unsettable model fails. + +Roll strict out as opt-in first, then flip the default. The reason is a real trap: the +advertised agent config default model is `gpt-5.5` (`schemas.py:15`, +`AgentConfigSchema.model` default). The playground sends that default back on every run, so +strict mode would treat `gpt-5.5` as an intentional choice on runs that never made one. On a +backend where `gpt-5.5` is not settable (for example a project whose only login is a Codex +OAuth exposing `openai-codex/gpt-5.5`, where a bare `gpt-5.5` may or may not resolve +depending on the suffix match), strict would start failing runs that pass today. So: +`AGENTA_AGENT_MODEL_STRICT` defaults to `false` (warn-and-fallback, the current behavior) in +the first release; ship Part 1 and the louder warning, confirm via the QA matrix that the +common models are settable, then flip the default to strict. Reconciling the advertised +default with the per-harness settable set (Part 3) removes the trap entirely. + +### In-process path, consistently + +`engines/pi.ts` is lenient in the other direction: `pickModel` falls back to `gpt-5.5`, then +to any non-mini model, then to `available[0]` (`pi.ts:101-110`). So a wrong requested model +silently runs a different one. Make it consistent: when `request.model` is set but does not +match any available model, raise the same `ModelNotSettableError` with the available ids, +rather than falling through to a default. Keep the no-model-requested fallback (the service +default) unchanged. + +This gives both backends one rule: a requested model that cannot run is an error with the +available set; no requested model uses the documented default. + +### Tests + +- sandbox-agent: a requested model with no provider key raises, and `conciseError` renders the + available-set message. No model requested still runs on the default. +- In-process: `request.model` not in `available` raises with the available ids; absent + `request.model` still falls back to the service default. + +## Part 3: expose the choices in the schema and `inspect` + +A caller cannot know which model values are valid without trying one and reading the error. +Surface the valid `model` values in the inspectable config schema, the way the platform +already surfaces the `model` catalog type, so the playground and any caller discover them up +front. + +### Boundary note: derive in the runner, do not widen the wire + +The model/provider auth config is derived inside the TS runner from `request.secrets` and +`request.model` (both already on the stable `/run` wire contract, `protocol.ts:210-211`). +Do not add a Pi-specific auth-config field to the wire or push the write into the Python +service. The runner already owns the per-run agent dir and the secret-to-env mapping; the +Python service stays thin (it decides what to run, the runner runs it, per +`services/agent/CLAUDE.md`). Part 3's schema work is the one piece that does belong in Python +(the SDK `AgentConfigSchema` and the service `/inspect`), because that is where the +inspectable catalog type lives. + +### The existing pattern + +The agent advertises its config schema through `AGENT_SCHEMAS` on `/inspect` +(`services/oss/src/agent/schemas.py`, wired at `app.py:156`). The `agent` element is the +`agent_config` catalog type (`AgentConfigSchema`, `sdk/utils/types.py:1065-1129`), resolved +by the playground against `/workflows/catalog/types/agent_config` +(`api/oss/src/resources/workflows/catalog.py`). Its `model` field is a plain string with +`x-parameter: grouped_choice` but **no choices** +(`sdk/utils/types.py:1087-1092`). The standalone `model` catalog type, by contrast, carries +`choices: supported_llm_models` and `x-ag-type: grouped_choice` +(`sdk/utils/types.py:1045-1054`). The agent's model field should carry choices the same way, +but the valid set is per-harness, so the choices must be harness-aware. + +### Proposal + +Populate the agent `model` field's choices with the available models, grouped by provider, +and keyed by harness. Two layers: + +1. **Static, schema-time (harness-neutral baseline).** Give `AgentConfigSchema.model` a + `choices`/`x-ag-metadata` like the `model` catalog type, sourced from the same + `supported_llm_models` list, so the playground renders a real grouped picker instead of a + free-text box. This is the cheap win and needs no runtime probe. Note per harness that the + effective set is constrained at run time (Pi: any provider with a vault key; Claude: its + own aliases). + +2. **Dynamic, run-time (the accurate set).** Add the available models to the `inspect` + response so a caller sees the true per-harness set for the current project. The runner + already knows them: pi-acp returns the `model` config option's `options` + (`allowedModels(session)`, `sandbox_agent.ts:524-536`), and the in-process path has + `modelRegistry.getAvailable()`. Expose a small read path so the service can answer "for + harness H in this project, the valid model values are ..." and fold it into the inspect + schema's choices. This is the harness-neutral surface with per-harness data: + + - **Pi / agenta**: the built-in models of every provider that has a vault key + (`provider/id` ids), plus any `models.json` custom models. + - **Claude**: Claude Code's aliases (`default`, `sonnet[1m]`, `opus[1m]`, `haiku`) as the + adapter reports them. + +Keep the schema shape harness-neutral (one `model` string field with grouped choices and +metadata); the *contents* differ by harness. Document the difference in the field +description so a reader of the schema alone understands why Pi and Claude show different sets. + +### Scope note + +Part 3 layer 1 (static choices) is small and independent; do it with Parts 1-2. Layer 2 +(runtime available-models in inspect) is a larger surface (a new read path plus a frontend +that requests it per harness/project) and can follow once Parts 1-2 land and are verified. + +## Recommendation and order + +Implement in this order: + +0. **Pre-fix (one line, do first):** correct the Together env-var mapping in `secrets.py` + (`TOGETHERAI_API_KEY` -> `TOGETHER_API_KEY`) and audit the rest of `_PROVIDER_ENV_VARS` + against Pi's `getApiKeyEnvVars`. This is an independent silent-drop bug and a trivial fix. +1. **Part 1** (write `auth.json` from resolved keys into the per-run agent dir, local and + Daytona; `models.json` only for custom/proxy models). This removes the root cause and + makes the common requested-model case work on sandbox-agent. Highest value, contained to + `sandbox_agent.ts` plus its tests. Must include the two prerequisites: create the per-run agent + dir for a model override (not only for skills/system-prompt), and fix `allowedModels` to + read `c.value`. Mind the `openai` vs `openai-codex` provider-id distinction. +2. **Part 2a** (louder warning + `allowedModels` fix + `AGENTA_AGENT_MODEL_STRICT` flag + defaulting to `false`). Ship the typed error path and the better message, but keep the + current warn-and-fallback default so nothing that passes today starts failing. This is the + safe half of the cost-trap fix. +3. **Part 3 layer 1** (static grouped choices on the agent `model` field) plus reconciling + the advertised default with the per-harness settable set. Cheap, and it removes the + `gpt-5.5`-default trap that blocks flipping strict on. +4. **Part 2b** (flip `AGENTA_AGENT_MODEL_STRICT` to default strict) once the QA matrix + confirms the common models are settable on every backend and the default is reconciled. + This is the final close of the cost trap. +5. **Part 3 layer 2** (runtime available-models in `inspect`). Defer to a follow-up; larger + surface, not blocking the fix. + +Part 1 plus Part 2a resolve the silent-drop symptom of F-007 safely; Part 2b closes the cost +trap fully once it is safe to fail loud by default. Part 3 prevents the next caller from +hitting it blind. diff --git a/docs/design/agent-workflows/projects/model-config/research.md b/docs/design/agent-workflows/projects/model-config/research.md new file mode 100644 index 0000000000..64ea8ab718 --- /dev/null +++ b/docs/design/agent-workflows/projects/model-config/research.md @@ -0,0 +1,256 @@ +# Pi model configuration: research and root cause of the default-only ACP path + +This doc explains how Pi configures providers and models, and why the sandbox-agent (ACP) path +exposes only the model value `default` while the in-process Pi path honors a requested +model.

First, Pi's Codex models are a **separate +provider** `openai-codex` (backed by `chatgpt.com/backend-api`, OAuth), distinct from the +API-key `openai` provider. Pi has **no** `openai-codex -> OPENAI_API_KEY` mapping, so a vault +`OPENAI_API_KEY` unlocks `openai/gpt-5.5`, not `openai-codex/gpt-5.5` +(`pi-ai/dist/models.generated.js:7667` is the `openai-codex` block; +`env-api-keys.js:95` maps `openai`). Second, Agenta's secret resolver has an env-var name +mismatch for Together: `secrets.py:33` maps `together_ai -> TOGETHERAI_API_KEY`, but Pi reads +`TOGETHER_API_KEY` (`env-api-keys.js:117`). So a Together vault key never registers as +configured auth in Pi. This is the same silent-drop class as F-007, for a different provider. + +### Config file locations + +Pi reads its config from the agent dir, which defaults to `~/.pi/agent` and is overridable +with `PI_CODING_AGENT_DIR` (`docs/providers.md`; `dist/config.js:404-410`).

It returns only models whose provider has +configured auth: + +```js +// node_modules/@earendil-works/pi-coding-agent/dist/core/model-registry.js:477-492 +getAvailable() { + return this.models.filter((m) => this.hasConfiguredAuth(m)); +} +hasConfiguredAuth(model) { + const providerApiKey = this.providerRequestConfigs.get(model.provider)?.apiKey; + return (this.authStorage.hasAuth(model.provider) || + (providerApiKey !== undefined && isConfigValueConfigured(providerApiKey))); +} +``` + +`authStorage.hasAuth(provider)` is true when the provider has a runtime override, an +`auth.json` entry, an env var key, or a `models.json` fallback resolver: + +```js +// node_modules/@earendil-works/pi-coding-agent/dist/core/auth-storage.js:274-284 +hasAuth(provider) { + if (this.runtimeOverrides.has(provider)) return true; + if (this.data[provider]) return true; // auth.json + if (getEnvApiKey(provider)) return true; // env var (OPENAI_API_KEY, ...) + if (this.fallbackResolver?.(provider)) return true; // models.json custom provider + return false; +} +``` + +So a model becomes available the moment Pi can see a credential for its provider, through +any of the four channels. No per-model config is needed for a built-in provider. This is the +single fact the whole root cause turns on. + +## How the two Agenta paths drive Pi + +### In-process path (works) + +`engines/pi.ts` runs Pi in the runner process. Before it reads the registry it applies the +request's vault secrets to `process.env`: + +- `runPi` wraps the whole run in `withRequestProviderEnv(request.secrets, ...)`, which sets + `OPENAI_API_KEY`/`ANTHROPIC_API_KEY`/etc. into `process.env` for the duration and restores + them after (`engines/pi.ts:72-99`, `200-205`). +- It then builds `ModelRegistry.create(authStorage)` and calls + `modelRegistry.getAvailable()` (`engines/pi.ts:219-228`). Because the env is set, + `hasConfiguredAuth` is true for the keyed provider, so that provider's models are in the + available list. +- `pickModel(available, request.model)` matches the requested model by `id` or + `provider/id` and falls back to `gpt-5.5` (`engines/pi.ts:101-110`, `230`). + +Result: the requested model resolves, because the env credential makes the registry expose +that provider's models. If the requested model's provider has no key, Pi falls back to a +default it can actually run, not to nothing. + +### ACP path (default-only) + +`engines/sandbox_agent.ts` drives Pi over ACP through the sandbox-agent `sandbox-agent` daemon and the +`pi-acp` adapter. The model is applied after the session is created: + +- The daemon is launched with provider keys in its env (`buildDaemonEnv` forwards + `OPENAI_API_KEY`/`ANTHROPIC_API_KEY`/... at `sandbox_agent.ts:380-391`; `runSandboxAgent` also does + `Object.assign(env, secrets)` at `sandbox_agent.ts:879-880`). +- pi-acp spawns the `pi --mode rpc` child with `env: process.env` + (`node_modules/pi-acp/dist/index.js:133-140`), so the daemon's env does reach the `pi` + process. +- On `newSession`, pi-acp probes `get_available_models` and builds the `model` config + category only when there is a non-empty available-model list: + +```js +// node_modules/pi-acp/dist/index.js:2442-2457 (buildConfigOptions) +if (state.models?.availableModels.length) { + configOptions.unshift({ + id: "model", category: "model", type: "select", + options: state.models.availableModels.map((model) => ({ value: model.modelId, ... })) + }); +} +``` + +- pi-acp's `getModelState` maps each available model to `value: "${provider}/${id}"` + (`pi-acp/dist/index.js:2459-2480`). So when real models exist, the allowed values are + `provider/id` strings, never the literal `default`. +- sandbox-agent stores that `newSession` response on the session record + (`createSession` -> `configOptions: cloneConfigOptions(response.configOptions)` at + `node_modules/sandbox-agent/dist/chunk-TVCDKGSM.js:1289-1299`). +- `applyModel` -> `setModel` -> `setSessionCategoryValue("model", wanted)` reads the + option's allowed values and throws `UnsupportedSessionValueError` when the requested value + is not among them (`chunk-TVCDKGSM.js:1465-1477`). The error string is exactly the one in + the QA log: "does not support value '...' for category 'model' (configId='model'). Allowed + values: ..." (`chunk-TVCDKGSM.js:601-611`). + +When the requested model's provider has a credential Pi can see, `availableModels` is +non-empty, the allowed values are real `provider/id` ids, and the matching `setModel` +succeeds. + +The precise failure mode (not "empty `getAvailable()`"). pi-acp throws auth-required when +the **raw** model list is empty (`rawModelsCount === 0`, `pi-acp/dist/index.js:1742`). So a +totally empty registry would fail the session, not silently fall back. The `default`-only +case is narrower: Pi returns some models, but **none whose provider/id matches the requested +model**, so there is no selectable option for what the caller asked. pi-acp's `getModelState` +then carries `currentModelId: availableModels[0]?.modelId ?? "default"` +(`pi-acp/dist/index.js:2495,2498`), and the daemon's `model` category ends up with a value +set the requested id is not in. `applyModel` catches the `UnsupportedSessionValueError` and +returns `undefined` (`sandbox_agent.ts:555-575`), so the harness keeps its own default. The net +result is the same (a requested model is silently dropped), but the cause is "no settable +option matching the requested id," which can be: the provider has no key, the env var is +misnamed (see the Together mismatch below), or the requested bare id is ambiguous across +`openai` and `openai-codex`. + +## Why the allowed set was only `default` (root cause) + +The available-model list Pi reports over ACP was empty (or did not include the requested +model's provider) because Pi could not see a credential for that provider in the ACP run's +agent dir or env. Concretely, on the Pi (Codex) ACP path: + +- The requested ids in F-007 were OpenAI ids (`gpt-5.5`, `gpt-4o-mini`). For those to be + available Pi needs the `openai` (or `openai-codex`) provider credential visible through + `auth.json`, an env var, or `models.json`. +- The per-run agent dir is seeded only from the login's `auth.json`/`settings.json` + (`prepareLocalAgentDir` at `sandbox_agent.ts:287-302`). If that login is a Codex OAuth token for a + different provider id, or if the project vault only carried a non-OpenAI key, Pi has no + credential for the requested OpenAI provider, so those models are filtered out of + `getAvailable()`. +- With no available models that match, pi-acp does not surface them, and the daemon's only + selectable model value collapses to `default`. `applyModel` logs "not settable ... using + harness default" and returns `undefined` (`sandbox_agent.ts:555-575`). + +For the Claude harness the allowed set `default, sonnet[1m], opus[1m], haiku` comes from the +separate `@zed-industries/claude-agent-acp` adapter, which exposes Claude Code's own model +aliases (the `[1m]` suffix is Claude Code's 1M-context alias naming). That path accepts the +aliases but rejects a full model id like `claude-haiku-4-5-20251001`, falling back to the +default (Sonnet). That is the cost trap in F-007. + +So the behavior is not "Pi only supports default." It is "our ACP run did not give Pi a +credential it recognizes for the requested model's provider in the agent dir, so Pi reported +no matching models, and `applyModel` silently fell back." The product owner's prior is +correct: our setup is wrong, not Pi. + +## What is missing, in one line + +The ACP per-run agent dir carries `auth.json` and `settings.json` but no `models.json`, and +the provider credential for the requested model is not reliably present in a form Pi's +registry counts as configured auth for that provider. Pi reads `models.json` and `auth.json` +from `PI_CODING_AGENT_DIR` (`config.js:404-422`); the runner already controls that dir +(`prepareLocalAgentDir`), so it is the natural place to write the provider/model config. + +## Sources + +Installed packages (authoritative for the running behavior): + +- `services/agent/node_modules/@earendil-works/pi-coding-agent` v0.79.4: `dist/config.js`, + `dist/core/model-registry.js`, `dist/core/auth-storage.js`, `docs/providers.md`, + `docs/models.md`, `docs/custom-provider.md`. +- `services/agent/node_modules/.pnpm/@earendil-works+pi-ai@0.79.4_*/.../pi-ai/dist/env-api-keys.js`. +- `services/agent/node_modules/pi-acp` v0.0.29: `dist/index.js`. +- `services/agent/node_modules/sandbox-agent` v0.4.2: `dist/chunk-TVCDKGSM.js`. + +Agenta code: + +- `services/agent/src/engines/pi.ts`, `services/agent/src/engines/sandbox_agent.ts`. +- `services/oss/src/agent/secrets.py`, `services/oss/src/agent/schemas.py`. + +Upstream docs (the repo is `earendil-works/pi`; `pi.dev/docs/*` paths 404, cite the repo): + +- `https://pi.dev/` +- `https://github.com/earendil-works/pi/blob/main/packages/coding-agent/docs/providers.md` +- `https://github.com/earendil-works/pi/blob/main/packages/coding-agent/docs/models.md` +- `https://github.com/earendil-works/pi/blob/main/packages/coding-agent/docs/custom-provider.md` +- `https://github.com/earendil-works/pi/blob/main/packages/ai/src/env-api-keys.ts` +- `https://github.com/svkozak/pi-acp` diff --git a/docs/design/agent-workflows/projects/provider-model-auth/README.md b/docs/design/agent-workflows/projects/provider-model-auth/README.md new file mode 100644 index 0000000000..fe4eae792f --- /dev/null +++ b/docs/design/agent-workflows/projects/provider-model-auth/README.md @@ -0,0 +1,49 @@ +# Provider, Model, and Auth for Agent Harnesses + +How an agent harness (Pi, Claude Code, Codex) picks its **provider + model** and gets the +**right credential injected**, across the SDK standalone path and the Agenta-connected path. + +This is a research-and-design workspace.

Creating and editing accounts stays on the existing secrets UI and API. We add +only a read list and a resolve. Full `ProviderAccount` CRUD and a storage migration are +later work, not v1. + +Multi-account falls out: a project holds `openai/default` and `openai/acme` side by side as +two `provider_key` secrets with different `Header.name`, and both resolve by slug. The only +behavior change is that we stop deduping by provider kind, so the second key stops being +silently dropped. + +### Self-managed credentials (the OAuth case) + +Research [research.md](research.md), Part 2.3 is unambiguous: Claude, Codex, and Pi all +**rewrite their OAuth credential file at run time** when the access token expires. Storing a +frozen `auth.json` as a secret is wrong, because it goes stale the moment the harness rotates +it, and a vault snapshot cannot be written back to the user's real login store. + +So we never store the rotating file. The self-managed mode (`source: runtime`) covers it: +the credential lives outside Agenta (the user's own sidecar login, an env var, or a cloud +identity), and Agenta injects nothing. A managed-OAuth path that stores a long-lived refresh +token and mints access tokens through each harness's credential-helper hook stays deferred. + +--- + +## Concern 3: ResolvedModelAccess and the resolver port + +The resolver's output is one neutral, least-privilege contract: + +```python +class ResolvedModelAccess(BaseModel): + provider: str + model: str # possibly rewritten for the deployment (e.g. a bedrock id) + deployment: str = "direct" + credential_mode: Literal["env", "runtime_provided", "none"] + env: Dict[str, str] = {} # the ONLY secret-bearing channel; one provider's vars, not the vault + endpoint: Optional[Endpoint] = None # base_url, api_version, region, headers, extras (non-secret) +``` + +`SessionConfig` gains `resolved_model_access`.

A request must not pass a project id + and reach another project's accounts. +2. **Provider match.** The resolved account's provider must equal `ModelSpec.provider`. + Reject a binding that points an OpenAI model at an Anthropic account. +3. **Resolve is service plumbing, not a secret reader.** `POST /vault/model-access/resolve` + returns a plaintext credential in its `env`. It must not be callable from the browser as a + general secret-read API. Only the agent service calls it, server-side. +4. **No secret values in logs, traces, errors, or the raw-JSON playground echo.** Traces carry + provider, model, deployment, and the account slug that ran. They never carry `env`. +5. **Clear inherited provider env before applying the plan.** On Agenta-managed runs the + runner must clear known provider env vars it would otherwise inherit, then apply only the + resolved plan. Today sandbox-agent copies process-env provider keys + (`services/agent/src/engines/sandbox_agent.ts:309`) and Daytona spreads `secrets` into the sandbox + (`:530`); both need the clear-then-apply discipline. +6. **`runtime` gates off the OAuth fallback.** `credential_mode = runtime_provided` must + inject nothing and must not upload Pi's fallback `auth.json`. The existing upload becomes + an explicit-mode behavior, not a default. +7. **Audit every resolve**: provider, model, account slug/id, credential mode, user, project. + Never the key material. +8. **Flagged, not fixed here.** `AGENTA_CRYPT_KEY` defaults to `"replace-me"` + (`api/oss/src/utils/env.py:410`). Out of scope; tracked in [status.md](status.md). + +--- + +## The duplicate-key landmine (must handle in v1) + +The two existing paths disagree on duplicate keys today. The agent path uses `setdefault`, so +the first key for a provider wins (`services/oss/src/agent/secrets.py:71`). The completion +path overwrites as it iterates, so the last key wins +(`sdks/python/agenta/sdk/managers/secrets.py:219`). A project may already hold two keys for +one provider. + +So the v1 resolve must not silently "pick the default." Rules: + +- Exactly one account for the provider: use it. +- A binding names an account: use that one. +- Multiple accounts, no binding, one flagged `is_default`: use the default and record which. +- Multiple accounts, no binding, none flagged: return a clear error asking the user to pick. + Do not guess. + +This preserves correctness and forces the choice into the open instead of inheriting an +accidental ordering. + +--- + +## Backward compatibility with prompts and completions + +Prompts and completions keep working, untouched. They resolve through the older +LiteLLM-shaped path that reads the same vault. We do not change that path, the vault storage, +or the `/secrets` API. We add an additive read view (provider accounts) and a service-side +resolve. The completion path never calls either. Existing keys read as accounts named from +their `Header.name`, or `"default"` when unnamed; no existing field changes meaning. + +Later, both paths can share this resolver so a user configures accounts once. That migration +has its own plan and is not in this stack. + +--- + +## Multi-account, end to end + +1. A project holds two OpenAI accounts in the vault: `default` and `acme` (two `provider_key` + secrets with different `Header.name`). +2. The agent config sets `model: { provider: openai, model: gpt-5.5 }`. The run binds an + account: the playground sends `binding: { source: project_account, account_ref: acme }`, + or a deployed environment holds that default. +3. `VaultModelAccessResolver.resolve` looks up `(project, provider=openai, acme)` and returns + `{ credential_mode: env, env: { OPENAI_API_KEY: }, model: gpt-5.5 }`. +4. The Pi/Codex/Claude adapter injects that one key. The other account, and every other + provider's key, never enters the run. + +With no binding and a single OpenAI account, the run uses it. With `source: runtime`, the +resolver returns `credential_mode: runtime_provided` and injects nothing. + +--- + +## Relationship to LiteLLM + +LiteLLM is the prompt-workflow completion path, not the agent path. Its current design is the +weak part: it keeps one key per provider via a dedup that shadows the second +(`sdks/python/agenta/sdk/managers/secrets.py:219`), uses a static model catalog +(`assets.py`), and forces custom providers to look OpenAI-compatible +(`secrets.py:147-150`). The resolver is the right place to unify both paths eventually. v1 +builds it for agents and leaves completions on their path behind a compatibility read of the +same secrets.

This page explains the idea, what it means for the playground, and +whether it touches prompts and completions. The formal data structures stay in +[design.md](design.md). + +## The problem today + +When an agent runs, it needs two things: a model, and permission to call that model. Agenta +handles the first and fumbles the second. + +Today you pick a model as one piece of text, like `gpt-5.5`. Agenta does not know which +provider that text belongs to.

The agent keeps the one it needs and +ignores the rest. + +That works, but it carries four problems: + +- You can store only one key per provider. A second OpenAI key gets dropped. +- You cannot point an agent at a custom endpoint (Azure, Bedrock, a proxy). +- The agent receives keys it never uses. That is wider exposure than the run needs. +- Subscription logins (a ChatGPT or Claude plan) do not fit, because they are not keys. + +## The idea + +Split the one fuzzy choice into two clear ones. + +1. **Which model.** A provider and a model, for example OpenAI and `gpt-5.5`. This stays in + the agent config. It is portable and describes intent, not secrets. +2. **Whose credentials.** Which account authorizes and pays for the call. This is not part of + the agent's portable identity, so it does not live in the committed config. It rides the + run instead: a tester pins an account on the request, and a deployed environment holds a + default account. (An earlier draft put this on the workflow revision. We moved it off, + because a revision gets exported and shared across projects, and a project-local account id + would break the moment the revision is reused elsewhere.) + +A **provider account** is a named credential: "OpenAI prod", "OpenAI sandbox", "Azure +eastus". You can keep several per provider. That is how multi-account works. When a run +starts, Agenta turns the chosen model plus the chosen account into one thing: the single +credential that run needs, and nothing more. + +## "Our stuff" versus "not our stuff" + +This is the part that was unclear. An agent can get its credentials in two ways. + +- **Agenta-stored, our stuff.** You saved an API key in Agenta. Agenta injects it. This is + exactly how prompts work today. +- **Self-managed, not our stuff.** Agenta holds no key. The agent gets its login from + somewhere else: a harness already logged in inside your own sandbox, an environment + variable on your machine, or a cloud identity. + +Why does the second way exist? Coding agents like Claude Code and Codex support subscription +logins, your ChatGPT or Claude plan. That login lives in a file the tool rewrites itself +every time the token refreshes. You cannot paste a moving file into a vault and expect it to +keep working. So for those logins the only honest answer is this: Agenta injects nothing, and +the agent uses its own login. We call that self-managed. + +Self-managed only matters for agents. Prompts and completions always use a stored key, so +they never meet this choice. + +## What the playground shows + +Today the model picker lets you see your configured providers, add a custom provider, and see +each provider's models. That stays. + +For agents we add one small choice next to the model: where its credentials come from. + +- **Use an Agenta account** (the default). Pick which account, or let the run use the + project's default for that provider. This is today's behavior, plus the ability to name and + choose among several accounts. +- **Self-managed.** Agenta injects nothing. A short hint says the sandbox or harness must + already be logged in. + +Adding a custom endpoint does not change. You still add a provider account that carries a +base URL. + +For the first version we keep it minimal: provider, model, an optional account, a +self-managed toggle, and a raw-JSON box. The JSON box lets you send exactly what you want +while we build the real control. + +## Does this break prompts and completions? + +No. They keep working, untouched. Three reasons. + +- Prompts and completions resolve their key through a different, older path that reads the + same vault. We do not change that path, the vault storage, or the existing `/secrets` API. +- We add a new read-only view on top for agents (provider accounts) and a new resolve step + that returns one credential instead of all of them. The completion path never calls it. +- Existing keys get a default account name through an additive backfill. No existing field + changes meaning. The only behavior we replace is the agent's "grab every key" step, and + that touches agent runs only. + +Later we can move prompts and completions onto the same accounts, so you configure your +accounts once and both paths use them.

The resolve path ships the full plaintext vault to the agent service every run. + +--- + +## Part 2: The three harnesses + +The single most important cross-cutting fact: **provider is first-class in all three**, and +**the env-var API-key plane is the one mechanism they all share and that is immutable**. +OAuth credential files, by contrast, are rewritten at run time by all three. + +### 2.1 Model selection + +| Harness | How model is chosen | Provider first-class? | Id format | +| --- | --- | --- | --- | +| Claude Code | `--model` / `ANTHROPIC_MODEL` / `model` in settings; SDK `ClaudeAgentOptions(model=...)` | Provider via backend flags, not in the id | `claude-opus-4-8`, aliases `opus`/`sonnet`; `us.anthropic.claude-...` on Bedrock | +| Codex | `model` and `model_provider` are **two separate keys**; SDK `ThreadOptions.model` | **Yes**, `model_provider` points at a `[model_providers.]` block | bare name, e.g. `gpt-5.3-codex` (never `provider/model`) | +| Pi | a resolved `Model` **object** via `getModel(provider, id)`; `createAgentSession({ model })` | **Yes**, `Model.provider` field; large `KnownProvider` union | display id is `provider/id`, e.g. `openai-codex/gpt-5.5` | + +Takeaway: normalize the neutral selection to a `{provider, model}` **pair**. Codex needs +them split; Pi needs a resolved object built from the pair; Claude needs the bare model plus +a backend flag. A combined `provider/model` string is fine on the wire if you split it on the +boundary. Watch the collision: in Pi, `openai` and `openai-codex` are different providers. + +### 2.2 Provider / base URL / custom endpoints + +- **Claude Code**: backend selection is by env flags: `CLAUDE_CODE_USE_BEDROCK=1`, + `CLAUDE_CODE_USE_VERTEX=1`, `CLAUDE_CODE_USE_FOUNDRY=1`, plus `ANTHROPIC_BASE_URL` for a + gateway, and per-backend base URLs (`ANTHROPIC_BEDROCK_BASE_URL`, etc.). Global env only; + the Agent SDK passes them through `options.env`. + (https://code.claude.com/docs/en/amazon-bedrock.md, .../google-vertex-ai.md, .../llm-gateway.md) +- **Codex**: `[model_providers.]` blocks with `base_url`, `env_key`, `wire_api` + (`responses` only now; `chat` deprecated), `query_params`, `http_headers`, + `env_http_headers`. Provider blocks live in **global** `~/.codex/config.toml`; project + files may not define providers or auth. Per-run you switch with `-c model_provider=...` or + `--profile`. (https://developers.openai.com/codex/config-advanced, + https://www.morphllm.com/codex-provider-configuration) +- **Pi**: every `Model` carries its own `baseUrl` and wire `api`. Custom endpoints come from + `~/.pi/agent/models.json` (merged with built-ins) or, programmatically, + `ModelRegistry.registerProvider(name, { baseUrl, apiKey, api, headers, oauth, models })`. + First-class built-ins exist for `azure-openai-responses`, `google-vertex`, + `amazon-bedrock`, OpenAI-compatible. All per-run when used as an SDK. + (vendored `pi-ai/dist/model-registry.d.ts`, `providers/register-builtins.js`) + +Takeaway: a neutral "custom connection" record (base_url, api/wire, api_version, headers, +region, extras) projects onto all three. Codex needs it written to global config or passed +via `-c`; Pi and the Agent SDK take it per-run. + +### 2.3 Authentication, and the OAuth rotation problem + +Every harness supports an **API key via env var** (immutable, stateless) **and** an **OAuth +subscription login stored in a file that the harness rewrites at run time**. + +| Harness | API key env | OAuth file | Does the tool rewrite the OAuth file at run time? | +| --- | --- | --- | --- | +| Claude Code | `ANTHROPIC_API_KEY` (or `ANTHROPIC_AUTH_TOKEN` bearer, or `CLAUDE_CODE_OAUTH_TOKEN`) | `~/.claude/.credentials.json` (Linux, mode 0600) or macOS Keychain | **Yes.** Refreshes the access token on 401 / TTL and writes it back; documented race/corruption issues under concurrency | +| Codex | `OPENAI_API_KEY` / `CODEX_API_KEY` / provider `env_key` | `~/.codex/auth.json` (path moves with `CODEX_HOME`) | **Yes.** Docs: "Codex refreshes tokens automatically during use before they expire."

(per-provider map) | `~/.pi/agent/auth.json` (path moves with `PI_CODING_AGENT_DIR`) | **Yes.** `auth-storage.js` checks `Date.now() >= cred.expires`, refreshes under a file lock, and `writeFileSync`s the new `{access, refresh, expires}`. API-key entries are static; only OAuth entries rotate | + +Sources: https://code.claude.com/docs/en/authentication.md; +https://developers.openai.com/codex/auth; vendored +`pi-ai/dist/auth-storage.{d.ts,js}`, `dist/env-api-keys.js`, `dist/utils/oauth/index.js`. + +Other relevant auth facts: + +- **Cloud creds** (Bedrock/Vertex) ride the normal AWS/GCP credential chains + (`AWS_*`, `GOOGLE_APPLICATION_CREDENTIALS`, ADC). All three harnesses support them. +- **Credential helper scripts**: Claude's `apiKeyHelper` (called on TTL/401), Codex's + `[model_providers..auth] command=...`, Pi's `AuthStorage.setFallbackResolver`. All + three have an "ask an external program for a fresh token" hook. This is the clean place to + plug a rotating-credential source if we ever need one. +- Pi's repo path already follows the right instinct: it injects provider keys as env vars and + only copies `auth.json` as a last resort when no key is present + (`services/agent/src/engines/pi.ts` `withRequestProviderEnv`, + `services/agent/src/engines/sandbox_agent.ts` `uploadPiAuthToSandbox`). + +### 2.4 Per-run vs global, and multiple accounts + +- **Pi** is fully per-run instantiable: model, `AuthStorage`, `ModelRegistry`, everything is + a constructor arg to `createAgentSession`. Multi-account is clean: pass a per-run in-memory + `AuthStorage`, or point each run at a different `PI_CODING_AGENT_DIR`. No built-in profile + concept; `auth.json` holds one credential per provider id. +- **Codex** is CLI-driven. Per-run knobs come via SDK `ThreadOptions` / `-c` / `--profile`. + Providers and auth files are global. It **does** have `[profiles.]` (each selecting a + model + provider + settings), which is the closest built-in multi-account mechanism, but + two keys for the *same* `openai` provider still means two provider blocks with different + `env_key`, or swapping `CODEX_HOME`/`auth.json`. +- **Claude Code** has no named-profile concept. One active credential per process/env, chosen + by precedence. Multi-account means separate env contexts. + +Takeaway: do not lean on each tool's built-in profile system (only Codex has one). Lean on +**per-run env injection** and, where needed, a **per-run home/agent dir**. That is the lowest +common denominator and the most isolatable. Pi's in-memory `AuthStorage` is the best-case +target; env injection is the universal fallback. + +### 2.5 ACP note + +When a harness runs over ACP behind the sandbox-agent runner, auth is still env vars inherited by the +spawned process. There is no separate ACP credential channel. The runner sets +`ANTHROPIC_API_KEY` / `OPENAI_API_KEY` / `CLAUDE_CODE_OAUTH_TOKEN` / base-URL env on the +daemon or sandbox, exactly as it does today. So an env-shaped injection plan is the right +neutral output regardless of in-process vs ACP vs Daytona. + +--- + +## Part 3: Synthesis for the design + +1. **Provider is first-class everywhere but absent in Agenta.** Add it. +2. **The env-var API-key plane is the universal, immutable substrate.** Make the neutral + output a contract dominated by env, with optional base-URL/extras. +3. **OAuth files are mutable and self-rotating.** Never store a frozen `auth.json` as a + secret and expect it to keep working. Run OAuth subscriptions self-managed (Agenta injects + nothing), never as a stored snapshot. +4. **Multi-account is a naming problem.** The vault already has `Header.name`; make it + load-bearing for standard providers too, and resolve to one account instead of + deduping by provider kind. +5. **Least privilege is free once the model carries a provider.** Resolve the account for + the selected provider only, and inject just that one credential. +6. **The harness adapter should stay credential-agnostic.** It already only sees `model` and + an env `secrets` map. Keep it that way; upgrade those two fields, do not teach it about + the vault. + + +## Part 4: 2026-06-24 route-free rework finding + +Facts from the existing vault shape: + +- `provider_key` secrets already carry a connection name (`header.name`), a typed provider + (`data.kind`), and a key (`data.provider.key`). +- `custom_provider` secrets already carry a connection name (`header.name` / `data.provider_slug`), + a deployment/provider kind (`data.kind`, e.g. `bedrock`, `vertex_ai`, `custom`), endpoint fields + (`data.provider.url`, `data.provider.version`), auth/config extras, and model slugs with computed + `model_keys` in the form `provider_slug/kind/model_slug`. +- The frontend stores custom-provider extras with the existing snake-case keys + `api_key`, `aws_region_name`, `aws_access_key_id`, `aws_secret_access_key`, `aws_session_token`, + `vertex_ai_project`, `vertex_ai_location`, and `vertex_ai_credentials`. A resolver must normalize + these into the harness env names; it must not require uppercase env-var keys in vault JSON. + +Claude Code findings: + +- `ANTHROPIC_CUSTOM_MODEL_OPTION` skips Claude Code's model-id validation only for adding a custom + picker entry. It does not make arbitrary models work. The configured backend still has to accept + the string. +- For Bedrock and Vertex, Claude Code is configured through backend flags and credentials, then model + ids are passed through via model settings/env. If a user selects `my-bedrock/bedrock/gpt-5.5`, + Agenta should pass the selected id through and let the backend fail if unsupported. Agenta does not + need to classify it as Sonnet/Opus/Haiku for v1. + +Recommendation: keep `ModelRef`/`ResolvedConnection` internally, but replace the new vault resolve +route with a service/SDK catalog built from existing `/secrets/`. This gives least-privilege at the +harness boundary while preserving the old vault API and schema. diff --git a/docs/design/agent-workflows/projects/provider-model-auth/status.md b/docs/design/agent-workflows/projects/provider-model-auth/status.md new file mode 100644 index 0000000000..aa172d0027 --- /dev/null +++ b/docs/design/agent-workflows/projects/provider-model-auth/status.md @@ -0,0 +1,86 @@ +# Status + +Source of truth for where this work stands.

That works in any + project. +- **Self-managed**: the config says "the agent brings its own login." That works anywhere too. +- **A specific connection**: the config stores its name. In another project, that name resolves to + that project's connection of the same name. If there is none, the run stops with a clear message + asking you to pick one. It never quietly uses a key for the wrong provider. -- **Use an Agenta account** (the default). Pick which account, or let the run use the - project's default for that provider. This is today's behavior, plus the ability to name and - choose among several accounts. -- **Self-managed.** Agenta injects nothing. A short hint says the sandbox or harness must - already be logged in. +One honest limit: a name is a role, not a frozen account. If two projects each have an "OpenAI prod" +connection holding different OpenAI keys, the name resolves to each project's own key. That is what +you want for "use my prod connection," and every run records which connection it actually used. -Adding a custom endpoint does not change. You still add a provider account that carries a -base URL. +To try a different connection for a single test run, you change it in the config you send when you +test, the same way you test any config before committing it. There is no separate override. -For the first version we keep it minimal: provider, model, an optional account, a -self-managed toggle, and a raw-JSON box. The JSON box lets you send exactly what you want -while we build the real control. +## "Our stuff" versus "not our stuff" -## Does this break prompts and completions? +An agent can get its credentials two ways: -No. They keep working, untouched. Three reasons. +- **Agenta-managed.** You saved a key in Agenta. Agenta injects it. This is how prompts work today. +- **Self-managed.** Agenta holds no key. The agent uses a login from somewhere else: a harness + already logged in inside your own sandbox, an environment variable on your machine, or a cloud + identity. You pick this when self-hosting or running a local backend. -- Prompts and completions resolve their key through a different, older path that reads the - same vault. We do not change that path, the vault storage, or the existing `/secrets` API. -- We add a new read-only view on top for agents (provider accounts) and a new resolve step - that returns one credential instead of all of them. The completion path never calls it. -- Existing keys get a default account name through an additive backfill. No existing field - changes meaning. The only behavior we replace is the agent's "grab every key" step, and - that touches agent runs only. +Self-managed exists mainly for subscription logins. Claude Code and Codex can use your ChatGPT or +Claude plan, whose login lives in a file the tool rewrites every time the token refreshes. You +cannot paste a moving file into a vault and expect it to keep working. So Agenta injects nothing and +the agent uses its own login. Self-managed only matters for agents; prompts always use a stored key. -Later we can move prompts and completions onto the same accounts, so you configure your -accounts once and both paths use them. That is a separate, optional step with its own -migration. It is not in this first stack. +## What the playground shows -## The names, old and new +For agents we add a small set of controls next to the model: a provider, a model, its params, and +where the credentials come from (a specific connection, the project default, or self-managed), plus +a raw-JSON box for the exact value. The form also knows what each harness can do: Claude Code only +reaches Anthropic models, Pi reaches many providers, so the options change with the selected +harness and hide what it cannot use. Adding a custom endpoint stays on the existing secrets screen. -The Codex review renamed most of the proposal. The vocabulary we are adopting: +## Does this break prompts and completions? -| Old (first draft) | New | -| --- | --- | -| `ModelRef` (with a connection inside) | `ModelSpec` (provider, model, params only) | -| `Connection` | `ProviderAccount` (user term: "provider account") | -| the connection reference, inside the agent config | `ModelAccessBinding`, on the run (request override or environment default), not on the committed revision | -| `InjectionPlan` | `ResolvedModelAccess` (the resolved access contract) | -| `ConnectionResolver` | `ModelAccessResolver` | -| `SidecarAuth` | `RuntimeProvidedAuth` (user term: "self-managed credentials") | +No. They keep working, untouched.

The chain below is the spine. The +two anchor skills are `plan-feature`, which produces the plan, and `implement-feature`, which +turns that plan into a landed change. + +``` +plan-feature -> implement-feature -> write-pr-description + | + implement-feature orchestrates, per slice: + debug-local-deployment · agent-workflows-qa · agent-replay-test + write-docs · style-editing · defer-todo · but +``` + +### Plan: plan-feature + +`plan-feature` (personal) opens a planning workspace under `docs/design//`. It +researches the repo first, then writes `context.md`, `plan.md`, `status.md`, and +`research.md`. That workspace is shared context for every later stage and for any human who +joins. `status.md` is the source of truth for progress and stays current to the end. + +### Implement: implement-feature + +`implement-feature` (personal) is the step after the plan. It does not write the whole feature +in one pass. Instead it orchestrates. The agent stays in the loop and spins a narrow subagent +for each phase: refresh the plan, implement a slice, review the diff, debug the slice against +the live stack until it works end to end, then improve the tests until they pass across the +matrix. Two rules hold throughout: every implementer is followed by a reviewer, and every fix +is followed by a retest. The skill leans on the four skills below for its debug, test, docs, +and branch phases. + +### Debug: debug-local-deployment + +`debug-local-deployment` (personal) drives the live Agenta stack on the dev box. It finds the +running port and compose project, logs into the playground in Chrome, reads container logs, +and hits the backend API with a project key. The debug phase of `implement-feature` runs this +skill in a loop: run, observe, fix, re-run, until the slice does what its acceptance check +says. + +### Test: agent-workflows-qa and agent-replay-test + +`agent-workflows-qa` (shared) defines the test matrix for the agent runtime. Its three axes +are the environment (in-process Pi, Rivet local, Rivet Daytona, and the local SDK), the +harness (`pi`, `agenta`, `claude`), and the capability under test. "Test with daytona, local +pi, and claude, on both the SDK and the UI" is exactly a walk across these cells. Each test +forces a capability with a token the model cannot guess, so a pass proves the capability ran. + +`agent-replay-test` (shared) pins a green cell so it stays green. It captures one real `/run`, +redacts the volatile fields, and writes a test that replays the recorded runner response +through the real SDK and service code with no live LLM. These tests run cost-free in the +default CI lane. + +### Document: write-docs and style-editing + +`write-docs` (shared) carries Agenta's documentation voice and structure, grounded in the +Diátaxis framework. `style-editing` (personal) applies Joseph Williams' clarity principles: +real characters as subjects, active voice, old information before new, the strongest word +last. The document phase of `implement-feature` drafts with the first and revises with the +second. + +### Park and ship: defer-todo, but, write-pr-description + +`defer-todo` (shared) records work the agent cannot finish now, with a clean repro, so nothing +is lost. `but` (personal, global) runs every version-control operation through GitButler +instead of raw git, which the repo requires. `write-pr-description` (shared) writes the PR +title and body the way a staff engineer would, once the branch is ready to push. + +## Adding a skill + +Write the skill at the lowest scope that fits. A team contract is shared; a personal workflow +is local. Give it a frontmatter `description` that names the trigger, because that line is how +the agent decides to load it. Keep the body a procedure, not a reference dump.

Resolved `code` and gateway/`callback` tools never reach that gate — they run through +the runner-side relay loop (`services/agent/src/tools/relay.ts`), which is a synchronous +fire-and-forget poll: `executeRelayedTool` (relay.ts:114-147) resolves a tool's `disposition` +via `resolveDisposition` (relay.ts:49-66) and, for `ask` or an unset disposition, collapses +onto the headless `permissionPolicy` and returns a refusal string +(`"...requires approval; denied in headless mode."`, relay.ts:128-129). There is no way for the +relay to emit an `interaction_request`, end the turn, and resume the same call on a later turn, +so an `ask` Composio/code tool can never actually prompt a human. The `TODO(S5)` markers at +`relay.ts:65` and `relay.ts:128` flag exactly this. The S3b `ask`->policy behavior was left +as-is per the slice scope. + +**Why it is deferred.** The relay loop has no turn-boundary model. The harness path can park +because the ACP permission request is itself the suspension point (the harness blocks awaiting +`respondPermission`); the relay just executes and returns a string inline. Giving the relay a +park/resume needs a different mechanism, not a tweak to `resolveDisposition`. + +**What it would take.** When the relay hits an `ask`/unset tool with no recorded decision: emit +an `interaction_request` (permission) keyed by the tool-call id (reuse the +`extractApprovalDecisions` lookup the responder already builds from the inbound messages), then +END the turn instead of returning a refusal — i.e. do NOT write the relay response file, let the +harness see an incomplete tool call, and surface the prompt. On the next turn, the runner reads +the stored decision from the replayed messages (same `{ approved: boolean }` envelope the +responder consumes) and either executes the relayed call or returns the denial. This couples the +relay to the run's turn lifecycle (today it is a standalone poll started/stopped around +`session.prompt`), so it likely needs the relay to share the responder's decision map and a way +to signal "park this turn" back up to the engine.

Neither is proven. Each `/invoke` is a cold sandbox that replays prior +turns as transcript text (`services/agent/src/engines/sandbox_agent/transcript.ts`), so whether +the model re-issues the identical tool call and the harness re-raises the gate on turn 2 is an +empirical property of the harness + the replayed transcript, not something the responder can +guarantee. The responder keys decisions by tool-call id AND tool name precisely because a cold +replay mints fresh ids each turn (so the name is the stable anchor) — but that only helps if the +gate is re-raised at all. + +**Why it is deferred.** It needs a live multi-turn run against the real harness over the +sidecar; it cannot be faked in a unit test (a fake harness re-raises on demand and proves +nothing about the real one). + +**The exact live test to run.** Against a running agent sidecar (e.g. the EE-dev compose stack; +see the `agent-workflows-qa` / `debug-local-deployment` skills), with a Claude agent configured +so a mutating builtin (or an `ask`-disposition tool) triggers a permission gate: + +1.

POST `/messages` again with the SAME `session_id=S`, replaying the full history plus a + `tool-approval-response` part (`approved: true`) for that tool call. Assert that this turn + the harness re-raises the gate, the stored decision resolves it to `always`, and the tool + ACTUALLY runs (a `tool-output-available` / real tool result appears, and the file is edited). +3. Repeat step 2 with `approved: false` in a fresh session and assert the tool stays un-run and + the model continues without it. + +If turn 2 does NOT re-raise the gate (the model does not re-issue the call after a cold replay), +the design needs a different resume mechanism (e.g. the runner replaying the approved tool's +result directly into the transcript rather than relying on the harness to re-ask).
