-# auto: add dietary preference chips to chat UI
+# auto: chat bubble layout — directional message alignment
## Why
-40%+ of recent traces show users explicitly typing dietary restrictions ("vegan gluten-free nut-free") in every single message — pure repetitive friction. The Flagsmith flag `auto_dietary_pref_chips` was created by a prior iterator run but never wired to any code. This PR implements the feature: a row of toggle chips (Vegan, Gluten-Free, Nut-Free, Dairy-Free) that persist across the session and auto-inject the selected preferences into each outgoing message. Trace evidence: e.g., `6f97e35c`, `64ca9586`, `7655b4d6`, `0bb3aee3`, `4532ec17`.
+The existing chat UI uses `ml-8`/`mr-8` indented blocks for messages — both user and assistant messages are visually identical blocks that differ only by their tiny "You"/"Chef" label. A proper directional bubble layout (user right-aligned, assistant left-aligned) is the highest-impact single visual improvement for a conversational UI. The operator's focus hint explicitly calls out "visual polish, spacing, typography, color, and layout."
## What
-- `web/components/chat.tsx`: on mount, fetches `/flags` from the backend; if `dietary_pref_chips` is true, renders a row of pill-shaped toggle chips below the model-tier selector. Active chips highlight in the accent colour. When the user sends a message, selected prefs are appended to the text sent to the agent (e.g. `"pasta recipe [dietary: Vegan, Gluten-Free]"`). The displayed bubble shows the raw user text without the injected suffix. Input placeholder also updates to reflect active preferences.
-- `api/main.py`: adds a `GET /flags` endpoint that reads Flagsmith flag values and returns them as JSON, so the frontend can query flag state without a JS SDK or exposed env vars.
+- `web/components/chat.tsx`: Added `bubbleLayout` state flag read from `/flags`; when enabled, messages render as directional flex bubbles — user messages right-aligned with warm orange-tinted background (`bg-accent/15`, `border-accent/30`, orange "You" label), assistant messages left-aligned with elevated card style (`rounded-2xl`, `shadow-sm`). Old layout preserved as fallback when flag is off.
+- `api/main.py`: Added `chat_bubble_layout` key to the `/flags` endpoint so the frontend can read the Flagsmith value.
## Flag
-- `auto_dietary_pref_chips` — default **off**. Enable in Flagsmith "cooking" project → Development to activate.

## How to test
```
-git checkout
+git checkout auto/improve-20260423-113311
pip install -e ".[dev]"
-cd web && npm install && npm run dev &
+# flip auto_chat_bubble_layout ON in Flagsmith Development environment
uvicorn api.main:app --port 8000 &
-# then flip auto_dietary_pref_chips ON in Flagsmith to see the chips appear
-# try: select "Vegan" + "Gluten-Free", type "give me a pasta recipe", send
-# confirm the agent receives the dietary context and respects it
-pytest -v tests/ -m agent_test
+cd web && npm install && npm run dev
+# open http://localhost:3000 and send a few messages
```
## Rollback
-Flip `auto_dietary_pref_chips` off in Flagsmith. No code revert needed — the UI silently hides the chips row when the flag is off.
-
-## Follow-ups
-- Candidate 2: Clickable example prompts in empty state (replace single static hint with 3–4 clickable suggestions).
-- Candidate 3: Copy-to-clipboard button on assistant message cards (recipe text is long; one-click copy is high-value QOL).

-## Baseline
-- Scenarios: 3/3 passed (100%)
-- Traces searched: 146 traces over last 7 days
+## Traces summary
+200 traces from last 7 days, all healthy (no thumbs-down annotations, no errors). Scenarios 4/4 green. Operator focus: **design improvements to chat UI**.
-## Evidence from traces & code inspection
-- 40%+ of all traces include dietary restriction queries ("vegan gluten-free nut-free") — users must retype these every single message.
-- Flag `auto_dietary_pref_chips` was created by a prior iterator run but **never implemented** in any code file.
-- UI has zero dietary controls beyond a model-tier dropdown; empty state shows only a single static hint.
-- No conversation-reset button, no copy-to-clipboard on assistant messages.
-- Error state shows raw HTTP status with no retry button.
+## Candidates
-## Candidate Changes
+| # | Title | Evidence | Impact | Risk | Score |
+|---|---|---|---|---|---|
+| 1 | **Chat bubble layout** — right-align user messages as warm-tinted rounded bubbles; left-align assistant messages as elevated cards | `chat.tsx` uses `ml-8`/`mr-8` indents — no directional alignment; messages look identical without tiny "You"/"Chef" label. Bubble layout is the single highest-impact visual improvement for a chat UI | High | Low | **1st** |
+| 2 | Header + page polish — gradient, sticky input, subtle separator | Page header is bare `text-2xl` with no visual weight | Med | Low | 2nd |
+| 3 | Implement `auto_starter_prompts` clickable chips (flag exists, no code yet) | Flagsmith flag registered, zero frontend implementation | Med | Med | 3rd |
-| # | Title | Evidence | Impact | Risk | Rank (I/R) |
-|---|-------|----------|--------|------|------------|
-| 1 | **Dietary preference chips (toggle chips UI)** | 40%+ traces show repeated dietary constraint text; `auto_dietary_pref_chips` flag exists but unimplemented; high user friction typing same prefs each message | **High** | Low | ⭐ 1st |
-| 2 | Clickable example prompts in empty state | Current empty state is a single static hint; users may not know what to ask; low discoverability | Med | Low | 2nd |
-| 3 | Copy-to-clipboard button on assistant messages | Recipes are long markdown; copying to use elsewhere is a common action with no affordance | Med | Low | 3rd |
-
-## Decision
-**Candidate 1 — Dietary preference chips** wins.
-
-Rationale: Clear trace evidence (typing "vegan gluten-free nut-free" in every message is high friction), an existing Flagsmith flag that was never wired up, and the operator hint "ui ui and more ui!" all align. The flag `auto_dietary_pref_chips` is used; default remains off so no live users are affected until a human enables it.
-
-Follow-ups (future runs):
-- Candidate 2: clickable example prompts
-- Candidate 3: copy-to-clipboard on assistant messages
+## Selected: Candidate 1 — Chat bubble layout
+Pure CSS/layout change, zero logic change — easiest non-regression to verify.
