Vyomel — Personal AI Execution Platform

A personal AI execution layer that turns natural-language intent into verified, permission-aware actions across a user's digital environment.

Vyomel is not a chatbot. A chatbot returns text. Vyomel changes state in the world — files, calendars, browsers, desktop applications, third-party APIs — and then proves the change actually happened before reporting success.

Status: M17 complete — roadmap M0–M17 finished. See docs/12-ROADMAP.md and docs/17-BUILD-LOG.md.


The thesis

Building an agent that clicks a button is easy and already commoditized. The unsolved problems are:

Problem Vyomel's answer
Agents lose work when a process dies Postgres as source of truth, Redis Streams as transport, leases + reapers + idempotency keys. Chaos-tested.
Agents claim success they can't prove Mandatory post-action re-observation. UNVERIFIED is a first-class state, so the system never has to lie.
Agents are given all-or-nothing trust A capability lattice (L0–L4) enforced in the runtime, with an invariant that L4 can never be auto-approved.
Agents forget everything A persistent personal context graph plus hybrid retrieval with precise citations.
Agents leak private data to the cloud Sensitivity classification with hard local-only routing that fails closed rather than escalating.
Agents can't be improved because nothing is measured A reproducible evaluation harness with ablations and CI regression gates.

Agents are a distributed systems problem wearing an AI costume. Vyomel is built on that premise.

Quick start

Prerequisites: Windows 11, Python 3.13, WSL2 with Docker. Full runbook in docs/13-ENVIRONMENT.md §4.

# 1. infrastructure (Postgres + pgvector, Redis) inside WSL
wsl -e bash -lc "cd /mnt/d/Vyomel/infra && docker compose up -d"

# 2. environment
py -3.13 -m venv .venv
.\.venv\Scripts\python.exe -m pip install -e ".[dev]"
Copy-Item .env.example .env      # then fill in API keys

# 3. verify + migrate
.\.venv\Scripts\python.exe -m vyomel.cli doctor
.\.venv\Scripts\python.exe -m vyomel.cli db upgrade

# 4. run
.\.venv\Scripts\python.exe -m vyomel.cli serve      # API + scheduler
.\.venv\Scripts\python.exe -m vyomel.cli worker     # in another shell

What works today (M3). Natural-language planning (vyomel do without --plan) is M5; until then tasks carry handwritten plans:

# see the 5-action DAG execute, then survive a worker being killed mid-flight
.\.venv\Scripts\python.exe demos\m1\run_demo.py

# create a task; --plan installs a handwritten DAG; --dry-run classifies without dispatch
vyomel do "list the docs" --plan .\plan.json
vyomel show <task_id>
vyomel tasks --status running
vyomel cancel <task_id>

# inspect and (policy-gated) invoke a single tool
vyomel tools list
vyomel tools show fs.write_file
vyomel tools invoke task.report --json '{\"summary\": \"ok\"}'

# the human-in-the-loop surface
vyomel approvals                                     # what is waiting on you
vyomel approve <approval_id>
vyomel modify <approval_id> --set value=85           # re-validated and re-classified
vyomel reject <approval_id> --reason "wrong student"

# ask the policy what it would do, without running anything
vyomel policy test fs.read_file '{\"path\": \"D:/Vyomel/.env\"}'
vyomel policy show

# the audit trail, and proof it has not been altered
vyomel audit tail --task <task_id>
vyomel audit verify

# semantic memory (ingest, query, entities, episodes)
vyomel memory ingest .\notes.md
vyomel memory query "ZX9QUNIQUE failover"
vyomel memory remember "prefers dark mode" --type preference
vyomel memory episodes --limit 10

Measured results

No number appears here unless a script in evals/ reproduces it. Results land as milestones complete. CI job eval-gate blocks PRs that regress gated metrics (evals/harness/compare.py vs evals/results/baselines/gated.json).
