+# Mini Apps — Implementation Plan
+
+> Status: **Phase 1 (UI + rendering, hand-coded apps)** in progress.
+> Branch: `feature/mini-apps`. Working dir: `apps/x`.
+
+## 1. What we're building (agreed design)
+
+A **Mini App** is a user-created, personal app that lives inside Rowboat under a
+**"Mini Apps"** sidebar tab, shown as cards; click a card to open and use it like
+a standalone app.
+
+The settled mental model:
+
+> A Mini App = **custom UI code** (a single self-contained HTML file: React +
+> Tailwind, no build step, runs in a sandboxed iframe) + an **agent "backend"**
+> that produces fresh **data** on a trigger + an optional **state store** + a
+> **scoped bridge** that lets the UI call real **Composio** actions.
+
+Key decisions (the "why" behind the architecture):
+
+- **Opens to a finished, populated screen.** The agent runs *before* open (on a
+  trigger); the UI just renders the latest result. Maps onto the existing
+  background-agents engine.
+- **Frontend/backend split.** Code = frontend, written once. Agent = backend,
+  produces fresh `data.json` each run. The UI is *not* regenerated per run.
+  Cheaper, faster, and the UI can't break on refresh.
+- **A data contract** ties the three pieces together: at creation the builder
+  produces a matched triple — UI code + data schema + agent instructions.
+- **Fully custom UI per app** (generated code), not a fixed block kit.
+- **Real interactivity** via a **scoped bridge** to Composio (each app declares
+  the integrations it may touch; scope drives both enforcement and the auth
+  prompt).
+- **Built by whatever engine is selected in the chat box** — Code Mode
+  (Claude Code / Codex) if the user has it, else the Copilot.
+- **Living apps:** refined by chatting; breakage is first-class (app surfaces
+  errors → "fix with copilot").
+- **State is an optional provided primitive** (per-app persistent store the agent
+  and UI can read/write). Stateless apps ignore it.
+- **Personal/local only** for now, but each app is a **self-contained folder**
+  so it can become portable later.
+
+### Framework for the apps
+
+Single self-contained `index.html` rendered in a sandboxed iframe.
+
+> **Learning (Phase 1):** remote CDNs do NOT work inside the sandboxed,
+> opaque-origin `srcdoc` iframe (React/Tailwind/Babel from unpkg/cdn.tailwindcss
+> failed → blank screen). Apps must be **fully self-contained, no network**.
+> Phase 1 therefore ships **vanilla HTML + CSS + JS** (no build, no transpile).
+> The React+Tailwind LLM-friendly target still stands for generation — but via a
+> **locally-bundled** runtime (esbuild-at-save, libs injected into the HTML),
+> never remote CDNs. The `window.rowboat` bridge is unchanged either way.
+
+The UI talks to the host through a `window.rowboat` **bridge** (the product
+surface *and* the security boundary):
+
+```
+rowboat.getData(): Promise<Data>             // latest agent output
+rowboat.onData(cb): void                      // re-render on refresh
+rowboat.getState() / setState(patch)          // per-app persistent store
+rowboat.callAction(scope, action, args)       // scoped Composio call
+rowboat.ready()                               // handshake: "send me data"
+```
+
+## 2. Phased roadmap
+
+1. **Surface + one real app (UI-first — THIS PHASE).** "Mini Apps" sidebar tab,
+   card grid, click to open. One **hardcoded** app (Twitter client) rendered in a
+   sandboxed iframe from a self-contained HTML file, reading static data through a
+   minimal bridge. Proves the *experience* and the *rendering path*. No agent,
+   no storage, no real Composio yet.
+2. **The scoped bridge.** Real interactive buttons → real Composio actions,
+   enforced against a per-app manifest scope; auth prompt on demand.
+3. **Generation.** Copilot/Code-Mode generates the UI+schema+agent triple from a
+   chat description. Rides the existing chat mode selector + `code-with-agents`.
+4. **Living apps + breakage recovery.** Conversational edits; error surfacing.
+5. **Scale & polish.** Context-overload windowing (e.g. 100 tweets); app
+   notifications (reuse `notify-user`).
+6. **(V2)** Drag an app into the main workspace (macOS-style).
+
+## 2b. Phase 2.5 — On-disk apps + `app://miniapp` serving (CURRENT)
+
+Move built-in apps out of source into `~/.rowboat/apps/<id>/`, served as static
+assets, with an optional background agent producing `data.json`. Sets up the
+copilot builder path (it will write the same folder layout). Team-agreed.
+
+### On-disk layout (one folder per app)
+```
+~/.rowboat/apps/<id>/
+  manifest.json     # id, title, description, source, scope[], active, lastRun,
+                    #   entry (default "dist/index.html"), agent (optional bg-task slug)
+  dist/             # static assets served via app://miniapp/<id>/...
+    index.html      # the app (self-contained; bridge shim inlined)
+  data.json         # latest agent output (read by the host, pushed to the app)
+```
+
+### Serving — `app://miniapp/<id>/<path>` (option A)
+- Extend `registerAppProtocol` (`apps/main/src/main.ts`) with a new host
+  `miniapp`: map `app://miniapp/<id>/<path>` → `~/.rowboat/apps/<id>/dist/<path>`
+  (path-traversal guarded; default `index.html`). `app://` is already registered
+  privileged (standard/secure/fetch/cors) so apps get a **real origin** —
+  remote CDNs/images and `fetch` work, unlike the opaque `srcdoc` origin.
+- The iframe loads via `src="app://miniapp/<id>/index.html"` (not `srcDoc`).
+  Sandbox becomes `allow-scripts allow-same-origin allow-popups allow-forms
+  allow-modals allow-downloads` — same-origin is its OWN `app://miniapp` origin,
+  still isolated from the renderer (different host).
+
+### Data path
+- Built-in/static `data` is seeded to `data.json`. A future background agent
+  (reuse bg-tasks engine, linked via manifest `agent`) overwrites it on schedule.
+- App keeps using `rowboat.onData`; the **host** now sources that data by reading
+  `~/.rowboat/apps/<id>/data.json` (via IPC) and posting it on `ready`. Composio
+  still flows through the bridge RPC. (GitHub app needs no `data.json` — it pulls
+  live via Composio.)
+
+### Steps
+1. **Shared schema** — `packages/shared/src/mini-app.ts`: `MiniAppManifest` zod +
+   type. Export it. New IPC channels in `shared/src/ipc.ts`:
+   - `mini-apps:seed` (req: `{apps:[{manifest, html, data?}]}`) — idempotent.
+   - `mini-apps:list` (res: `{manifests: MiniAppManifest[]}`).
+   - `mini-apps:get-data` (req `{id}`, res `{data: unknown|null}`).
+2. **Main** — `apps/main/src/mini-apps-handler.ts`: `seedApps` (write
+   manifest/dist/data to `~/.rowboat/apps/<id>/` only if absent), `listApps`
+   (read manifests), `getAppData` (read data.json). Register handlers in
+   `ipc.ts`. Extend `registerAppProtocol` for the `miniapp` host.
+3. **Renderer** — keep `MiniApp` defs + `buildMiniAppHtml`; `registry.ts` adds
+   `toSeed(app)` (→ `{manifest, html, data}`). `MiniAppsView`: on mount → `seed`
+   → `list` → render cards from manifests. `MiniAppFrame`: take the manifest,
+   load `src=app://miniapp/<id>/<entry>`, on `ready` fetch `mini-apps:get-data`
+   and post it; RPC scope from `manifest.scope`.
+4. **Verify**: GitHub app end-to-end from disk (`~/.rowboat/apps/github-radar/`),
+   then the others; confirm connect + live PRs still work.
+
+### Out of scope here (next: copilot builder, tomorrow)
+Copilot writing a new app folder + an associated background agent; the agent
+browsing via embedded browser for social feeds; copilot verifying Composio wiring
+by actually calling tools before finalizing.
+
+## 2c. Remaining work (after on-disk move)
+
+Done so far: surface + runtime (Phase 1), real scoped Composio bridge (Phase 2),
+apps on disk served via `app://miniapp` (Phase 2.5).
+
+**Next — Copilot builder (demo target).**
+- Copilot creates an app folder in `~/.rowboat/apps/<id>/` via the `mini-apps:seed`
+  install primitive (writes `manifest.json` + `dist/index.html`).
+- Copilot must **verify wiring by actually calling Composio tools** and inspecting
+  the returned data before finalizing — never speculate the shape.
+- Give generated apps the bridge contract — prefer **serving a canonical shim**
+  from the protocol (e.g. `app://miniapp/__bridge__.js`) over inlining.
+
+**Background-agent data pipeline (deterministic).**
+- Reuse the existing bg-tasks engine; link via `manifest.agent`.
+- The agent does NOT write files. It **returns structured data validated against
+  the app's data schema**; the bg-task **runner (code) atomically writes the
+  app's `data.json`** (temp→rename, keep last-good on failure). Path / atomicity
+  / validation / fallback all live in code — only the *content* is LLM-driven.
+- Social feeds (Twitter/LinkedIn/Reddit): the agent browses via the embedded
+  browser, curates, returns data → runner writes `data.json`.
+
+**Later (roadmap).**
+- Living apps + breakage recovery (edit by chat; surface errors → fix-with-copilot).
+- Scale/polish: context-overload windowing; app notifications; design-consistency
+  / component templates (team-deferred).
+- V2: drag an app into the main workspace.
+
+## 2d. Mini App builder skill — spec
+
+A Copilot skill (`build-mini-app`, in `packages/core/src/application/assistant/
+skills/`) that turns a chat request into an installed app under `~/.rowboat/
+apps/<id>/`. Copilot orchestrates; the actual code-writing is delegated by the
+chat's active engine (the chip), but the on-disk artifact is identical either way.
+
+**Trigger + intent gate** (like live-note/background-task signal tiers):
+- **Strong (build directly):** "make/build/create an app · mini app · dashboard
+  for …", "turn this into an app".
+- **Medium (CONFIRM FIRST):** requests that could be a one-off answer or a
+  recurring app — e.g. "show me my open PRs", "track competitor launches". Ask:
+  "Want this as a Mini App you can reopen, or just a one-time answer?" Build only
+  on yes. (Building installs a folder + maybe a bg agent + an OAuth prompt — too
+  heavy to trigger on a casual question.)
+- **Anti (do NOT build):** clearly one-off lookups/questions → just answer.
+
+**Flow:**
+1. **Scope the app** — derive `id` (slug), `title`, `description`, `source`, the
+   Composio `scope[]`, and whether it's **agent-backed** (scheduled data) or
+   **live** (calls Composio on use).
+2. **Verify wiring BEFORE building** (mandatory, engine-agnostic) — ensure the
+   toolkits are connected (prompt OAuth if not), then actually call the needed
+   tools (`composio-search-tools` → `composio-execute-tool`), inspect the REAL
+   returned data, and derive the **data schema from actual responses** — never
+   guess the shape.
+3. **Pick the writer (branch):**
+   - **Code Mode active** → create the folder + a manifest skeleton, then
+     `code_agent_run` with `cwd = ~/.rowboat/apps/<id>/` to author
+     `dist/index.html` against the verified schema + bridge contract; it can
+     iterate/test on-device.
+   - **No Code Mode** → Copilot writes `dist/index.html` itself (from the app
+     template + bridge shim) and installs via `mini-apps:seed`.
+4. **Bridge contract** — generated app references the canonical shim
+   (`app://miniapp/__bridge__.js`) and uses `window.rowboat`
+   (`getData/onData`, `isConnected/connect`, `searchTools/callAction`).
+5. **Data pipeline (if agent-backed)** — create a background task (existing
+   bg-tasks engine), set `manifest.agent` to its slug. The agent **returns
+   schema-validated data**; the **runner writes `data.json` deterministically**
+   (temp→rename, last-good on failure). App reads it via `onData`.
+6. **Finalize** — write `manifest.json` (incl. `scope`, `agent?`), ensure
+   `dist/index.html`, install → app appears in the gallery (`mini-apps:list`).
+   Confirm end-to-end (open it; data loads).
+
+**Infra this needs (repo side):**
+- Serve the canonical bridge shim from the protocol: `app://miniapp/__bridge__.js`
+  (move the shim out of per-app inlining into served infra).
+- bg-tasks runner: when a task is app-linked, validate its structured output
+  against the app schema and write that app's `data.json` (deterministic write
+  mode) instead of `index.md`.
+- A `build-mini-app` skill registered in the skills catalog.
+
+## 3. Phase 1 — detailed implementation
+
+UI-first. Everything hand-coded; no `~/.rowboat` storage, no IPC, no agent yet.
+We *do* mirror the eventual shapes so later phases slot in.
+
+### 3.1 New files (renderer)
+
+| File | Purpose |
+|------|---------|
+| `apps/renderer/src/mini-apps/types.ts` | `MiniApp` type (id, name, description, icon, accent, scope, html, data). |
+| `apps/renderer/src/mini-apps/registry.ts` | Hardcoded list of `MiniApp`s for Phase 1. |
+| `apps/renderer/src/mini-apps/apps/twitter-client.ts` | The sample app: self-contained HTML (React+Tailwind+Babel CDN) + static `data`. |
+| `apps/renderer/src/components/mini-apps-view.tsx` | Card grid; internal `selectedAppId` state; renders grid or open app. |
+| `apps/renderer/src/components/mini-app-frame.tsx` | Sandboxed iframe (`srcdoc`) + `window.rowboat` postMessage bridge (data wired; actions stubbed → toast/log). |
+
+The bridge message protocol (host ↔ iframe), defined once and shared:
+- iframe → host: `{ type: 'rowboat:mini-app:ready' }`,
+  `{ type: 'rowboat:mini-app:action', id, scope, action, args }`,
+  `{ type: 'rowboat:mini-app:setState', patch }`
+- host → iframe: `{ type: 'rowboat:mini-app:data', data }`,
+  `{ type: 'rowboat:mini-app:state', state }`,
+  `{ type: 'rowboat:mini-app:action-result', id, ok, result?, error? }`
+
+### 3.2 Wiring into `App.tsx` (mirror the `bg-tasks` view exactly)
+
+Add a first-class `apps` view. Edit sites (all mirror an existing view):
+
+1. **Tab path const** (~L198): add `const APPS_TAB_PATH = '__rowboat_mini_apps__'`.
+2. **Tab predicate** (~L374): `const isAppsTabPath = (path) => path === APPS_TAB_PATH`.
+3. **ViewState union** (~L636): add `| { type: 'apps' }`.
+4. **`parseDeepLink`** (~L713): add `case 'apps': return { type: 'apps' }`.
+5. **State flag** (~L825): `const [isAppsOpen, setIsAppsOpen] = useState(false)`.
+6. **Tab title** (~L1253): `if (isAppsTabPath(tab.path)) return 'Mini Apps'`.
+7. **Tab activation → flag** (~L3269, ~L3443): set `isAppsOpen` from tab path.
+8. **Closing-tab guard** (~L3376): add `&& !isAppsTabPath(closingTab.path)`.
+9. **`currentViewState`** (~L3770): `if (isAppsOpen) return { type: 'apps' }`
+   (place alongside bg-tasks; add to deps array).
+10. **`ensureAppsFileTab`** (~L3853): mirror `ensureBgTasksFileTab`.
+11. **`openAppsView`** (~L3953): mirror `openBgTasksView`; reset all other flags,
+    `setIsAppsOpen(true)`, `ensureAppsFileTab()`.
+12. **`applyViewState` switch** (~L4195): add `case 'apps':` mirroring `bg-tasks`.
+13. **Add `setIsAppsOpen(false)`** to every *other* view's reset block (the
+    shared multi-`set...(false)` lines) so opening another view clears apps and
+    closing it doesn't fall back to apps. Use targeted edits per block.
+14. **Derived booleans** that OR all view flags (isFullScreenChat,
+    rightPaneAvailable, inFileView, rightPaneContext, viewOpen, keyboard guards):
+    add `|| isAppsOpen` / `&& !isAppsOpen` consistently (search `isBgTasksOpen`).
+15. **Tab-path mapping** (~L4668): add `: isAppsOpen ? APPS_TAB_PATH`.
+16. **Render branch** (~L5894): add `) : isAppsOpen ? (<MiniAppsView ... />`.
+
+### 3.3 Sidebar entry (`sidebar-content.tsx`)
+
+- Add `onOpenApps?: () => void` prop (~L163) and destructure (~L412).
+- Add a `SidebarMenuButton` with `isActive={activeNav === 'apps'}` and a
+  `LayoutGrid` (lucide) icon, label "Mini Apps", in the lower nav group near
+  "Background agents" (~L830).
+- Thread `activeNav === 'apps'` from the parent (App.tsx passes `activeNav` based
+  on `isAppsOpen`, mirroring how `'agents'` is derived ~L5651).
+- Wire `onOpenApps={openAppsView}` at the `SidebarContent`/home call sites
+  (~L5657, ~L5832).
+
+### 3.4 The sample app (twitter-client)
+
+Self-contained HTML string. React + ReactDOM + Babel-standalone + Tailwind, all
+via CDN. Renders three sections — **To read / To repost / To respond** (reply
+pre-drafted) — from data delivered via `rowboat.onData`. Buttons call
+`rowboat.callAction('twitter', ...)`; in Phase 1 the host just toasts/logs and
+returns a fake ok. Static `data` lives next to the HTML.
+
+> Note: CDN scripts require network + `allow-scripts` in the sandbox. The frame
+> uses `sandbox="allow-scripts allow-popups allow-forms allow-modals"` — **no**
+> `allow-same-origin` (keeps the app from reaching host cookies/storage; the
+> bridge is the only channel). Verify CDN loads under this sandbox during testing;
+> if blocked, fall back to bundling the libs locally as a renderer asset.
+
+### 3.5 Verify
+
+- `cd apps/x && npm run deps && npm run lint` compiles clean.
+- `npm run dev`: "Mini Apps" appears in the sidebar; opens the card grid; clicking
+  the Twitter card renders the app full-screen in the pane; sections populate from
+  data; clicking a button shows the stubbed action result; tabs/back/forward and
+  switching to other views behave like every other view.
+
+## 4. Out of scope for Phase 1 (later phases)
+
+`~/.rowboat/apps/<slug>/` storage + IPC; the agent backend (reuse bg-tasks
+engine); real Composio execution through the bridge; per-app scope enforcement &
+auth prompting; generation via Copilot/Code-Mode; persistent state store;
+conversational editing & error recovery; the V2 workspace drag.

+# Calls (Video Mode) — Deep Dive
+
+Calls let the user talk to the assistant hands-free while it *sees* them
+(webcam) and their screen (screen share). There is ONE call engine —
+continuous listening, auto-submitted utterances, forced read-aloud TTS, frame
+capture — entered through four presets that differ only in starting devices.
+This doc covers the product flow, the technical pipeline, and the LLM prompt
+surface with exact pointers.
+
+## Product flow
+
+The composer has a **call split-button** (`chat-input-with-mentions.tsx`).
+The main click is the "work together" default — preset `share`: screen
+sharing ON, camera OFF, floating pill, so the user keeps working while the
+assistant watches along (the button tooltip discloses the screen share). The
+chevron menu holds the deviations. While a call is live the button turns red
+and ends it.
+
+| Preset | Starting devices | First surface |
+|--------|------------------|---------------|
+| `share` — main click | screen on, camera off | floating pill |
+| `voice` — "Voice call" | camera off, screen off | floating mascot pill |
+| `video` — "Video call" | camera on | full-screen call |
+| `practice` — "Practice session" | camera on, + coaching persona | full-screen call |
+
+**One surface rule** (`callSurface` in `App.tsx`): full screen and screen
+sharing are mutually exclusive in both directions — a full-screen call covers
+the screen, so sharing it would show the call itself.
+
+- sharing → floating popout, always (pill = working)
+- not sharing → full screen unless `callMinimized` (full screen = facing
+  each other)
+- expanding the pill auto-STOPS any share; minimizing the full-screen call
+  auto-STARTS one (the pill exists to work together) — presenting from full
+  screen likewise collapses to the pill
+- the camera toggle never changes the surface: turning it on from the pill
+  puts your video IN the pill; expanding is its own explicit action
+
+**Screen-share consent** is three-layered: a toast the moment any share
+starts ("Your screen is being shared… [Stop sharing]"), a persistent
+"Sharing screen" badge on the pill, and macOS's purple recording indicator.
+If the auto-share fails (Screen Recording permission not granted) the call
+starts anyway as a voice call, with a toast linking to System Settings.
+Practice/coaching is always an explicit choice — expanding to full screen
+never turns the coach on.
+
+In-call controls (identical bar on both surfaces): mic mute, camera toggle
+(silhouette avatar while off, no webcam frames captured), screen share
+toggle, mascot ⇄ "R" letter avatar, end call. **Mute is a full input
+pause**, not just audio — mic audio stops reaching Deepgram
+(`useVoiceMode.setPaused`, OR'd with the automatic thinking/speaking pause)
+AND camera/screen frame capture stops (`useVideoMode.setCapturePaused`;
+`collectFrames()` returns nothing while muted, so typed messages carry no
+frames either), letting the user talk to someone in the room without the
+assistant listening in. Devices stay acquired for instant unmute (camera
+light and macOS share indicator stay on — the pill's share badge switches to
+"Sharing paused"), the status chip shows "Muted" instead of "Listening",
+and assistant output is unaffected (in-flight speech keeps playing; Stop
+handles that). Mute resets to off at call start/end. While the assistant is thinking or speaking, a
+red **Stop** button appears on the mascot tile — it silences TTS instantly,
+skips queued voice segments, and aborts the run if it's still generating
+(stopping a run from anywhere, including the composer, also silences TTS). Captions of the in-progress utterance and the
+assistant's spoken line run along the bottom. Typing in the composer still
+works mid-call; frames ride along with typed messages too.
+
+Outside calls the composer keeps exactly one voice affordance: the **mic
+button** (push-to-talk dictation, untouched). Spoken responses exist only
+inside calls (forced full read-aloud, off on hang-up). The old video
+dropdown, talking-head toggle, read-aloud headphones toggle, and summary/full
+TTS dropdown are all retired — a per-message "read aloud" action on assistant
+messages is the planned replacement for text-in/voice-out.
+
+The call button is disabled unless both voice input (Deepgram) and voice
+output (TTS) are configured. `call_started` (with `preset`) is captured in
+PostHog — the adoption metric for this feature.
+
+**Popout mechanics**: a small always-on-top frameless window (camera tile
+when on + mascot tile, live caption, control bar) floating over every app —
+including Rowboat. Control-bar actions round-trip `video:popoutAction` →
+main → `video:popout-action` → app window, which owns the mic/camera/capture;
+`expand` also refocuses the app window (handled in main).
+
+## Frame pipeline
+
+`apps/renderer/src/hooks/useVideoMode.ts` runs one capture pipe per source
+(stream → offscreen `<video>` → canvas JPEG → ring buffer):
+
+- Cadence: 1 fps (`CAPTURE_INTERVAL_MS`, line 20); ring buffer ~2 min.
+- Webcam: 512px wide, JPEG q0.65, max **12 frames/message** (lines 21, 31).
+- Screen: 1280px wide (text legibility), JPEG q0.7, max **4 frames/message**
+  (lines 24, 32).
+- `collectFrames()` drains frames buffered since the last send, evenly
+  sampled down to the caps, always keeping the newest; grabs one final frame
+  at the moment of send. Falls back to the single latest frame for
+  rapid-fire messages.
+
+`App.tsx` `handlePromptSubmit` attaches the drained frames (whenever a call
+is live) to the outgoing message as `UserImagePart`s and sets
+`composition.videoMode` when the camera or screen is active, plus
+`composition.coachMode` during a practice session. Frames also become
+`isVideoFrame` display attachments (filmstrip in the transcript —
+`chat-message-attachments.tsx`; history hydration in
+`lib/run-to-conversation.ts`).
+
+## Message schema & model encoding
+
+- `packages/shared/src/message.ts:51` — `UserImagePart`: inline base64
+  (`data`, `mediaType`), `source: 'camera' | 'screen'`, `capturedAt`. Unlike
+  file attachments (path references read via the `LLMParse` tool), image
+  parts go to the model as real multimodal image parts.
+- `packages/core/src/agents/runtime.ts` `convertFromMessages` (~line 1013):
+  emits a context line (frame counts + time span), then labeled groups —
+  a `"Webcam frames (oldest to newest):"` text part before camera images and
+  a `"Screen-share frames (oldest to newest):"` text part before screen
+  images — so the model never confuses the user with their screen.
+- Frames stay inline in history (no pruning) deliberately: pruning would
+  bust provider prefix caching every turn and cost more than it saves.
+- The auto-permission classifier stringifies + truncates content to ~3KB per
+  message, so inline base64 can't blow up its prompt.
+
+## Hands-free voice loop
+
+`apps/renderer/src/hooks/useVoiceMode.ts`:
+
+- `startContinuous(onUtterance)` (line 404): push-to-talk params but with
+  `endpointing=1800` (line 25) so thinking pauses don't cut the user off,
+  plus `utterance_end_ms=2000` (line 38) as a second end-of-speech signal.
+  **Gotcha:** Deepgram's `speech_final` usually arrives on a result with an
+  EMPTY transcript — empty finals must reach the endpoint check or
+  utterances never complete (see the NOTE in `ws.onmessage`).
+- `setPaused(true)` (line 414) while the assistant thinks/speaks: drops mic
+  audio (so TTS is never transcribed back), discards half-heard buffer,
+  sends Deepgram KeepAlives every 5s. `App.tsx` drives this from
+  `activeIsProcessing || tts.state !== 'idle'`.
+- Mid-call socket drops reconnect after 1s; the offline audio backlog is
+  capped (~30s).
+
+Call lifecycle lives in `App.tsx` `startCall(preset)` / `endCall()`:
+entering a call saves/forces TTS settings, cancels any push-to-talk
+recording, and starts the continuous loop; ending restores everything.
+Push-to-talk is disabled while a call owns the mic.
+
+## Popout window
+
+- The popout window keeps the Dock icon alive: it uses
+  `setVisibleOnAllWorkspaces(true)` WITHOUT `visibleOnFullScreen` — that flag
+  turns the app into a macOS "agent" app and hides its Dock icon while the
+  window exists (looks like Rowboat vanished). Trade-off: the popout doesn't
+  hover over other apps' fullscreen Spaces.
+- Shown iff the derived `callSurface === 'popout'` (effect in `App.tsx`).
+  Renderer asks `video:setPopout {show}`; main creates a frameless,
+  `alwaysOnTop` ('floating'), all-workspaces BrowserWindow at the top-right
+  of the primary display, loading the renderer bundle with `#video-popout`
+  (`apps/renderer/src/main.tsx` branches on the hash →
+  `components/video-popout.tsx`).
+- Call state streams over the `video:popout-state` push channel; main caches
+  the last payload and replays it on popout load. Shown with
+  `showInactive()` so it never steals focus.
+- The popout captures its **own** camera preview (MediaStreams can't cross
+  windows) and synthesizes the mascot mouth level (no audio in that window).
+- `video:popoutAction` relays control-bar actions to the app window, matched
+  only by real app-window URLs — `getAllWindows()` also contains hidden
+  utility windows (PDF export) that must not be shown or messaged.
+
+## Permissions
+
+- Camera: `voice:ensureCameraAccess` settles the macOS TCC prompt before
+  `getUserMedia` (same pattern as the mic). `NSCameraUsageDescription` is in
+  `forge.config.cjs` `extendInfo`.
+- Screen: `getDisplayMedia` is auto-approved with the primary screen by
+  `setDisplayMediaRequestHandler` in `main.ts` (no picker);
+  `meeting:checkScreenPermission` registers the app in macOS Screen
+  Recording settings on first use.
+
+## LLM prompts catalog
+
+| Prompt | Where |
+|--------|-------|
+| `# Video Mode (Live Camera)` system section — how to use webcam frames, coaching guidance, screen-share rules ("treat the screen as the primary subject", "last screen frame is current"), etiquette (never comment on appearance) | `packages/core/src/agents/runtime.ts:386` (`composeSystemInstructions`, gated on `videoMode`) |
+| `# Practice Session (Coach Mode)` system section — coaching persona: specific/actionable feedback after each take, one-sentence interjections mid-flow, structured debrief on wrap-up | `composeSystemInstructions`, gated on `coachMode` (directly after the video section) |
+| "Driving the app" paragraph in the video-mode section — on calls, prefer app-navigation read-view/open-item (show while telling) over describing or squinting at frames | same `# Video Mode` section; full action docs in the `app-navigation` skill (`application/assistant/skills/app-navigation/skill.ts`) |
+| Per-message frame context line `[Video mode: N live webcam frames … and M frames of the user's shared screen …]` + group labels | `packages/core/src/agents/runtime.ts` (`convertFromMessages`) |
+| `videoMode` / `coachMode` composition overrides (session-sticky; flips bust prefix cache) | `packages/core/src/turns/bridges/real-agent-resolver.ts` (`CompositionOverrides`); set from `App.tsx` `sendConfig` |
+
+Voice input/output prompt sections (`# Voice Input`, `# Voice Output`) are
+reused untouched — calls set `voiceInput` per utterance and force
+`voiceOutput: 'full'`.
+
+## Driving the app on a call
+
+The assistant can drive the Rowboat UI itself via the extended
+`app-navigation` builtin ("app driver"): `open-view` (any main view),
+`read-view` (returns the emails / background agents / chat-history data the
+view renders — and the renderer simultaneously navigates there so the user
+watches it happen), and `open-item` (a specific email thread, note,
+background agent, or past chat, deep-linked on screen). Data comes from the
+same core functions the UI's IPC handlers use (`listImportantThreads` /
+`searchThreads`, background-task `listTasks`, the sessions container) — no
+OCR of screen frames. The renderer applies results via
+`applyAppNavigation` in App.tsx, fed from BOTH event paths: the legacy
+`runs:events` ref-poll AND a watcher over the session-chat conversation (the
+turn runtime does not emit legacy run events — miss this and navigation
+silently no-ops while the tool reports success). Session switches seed the
+watcher so replaying history never navigates. During a call, visible
+navigations also collapse the full-screen call to the pill and focus the app
+window (`app:focusMainWindow`) so the user actually sees the screen change.
+Card labels live in `lib/chat-conversation.ts`. The call prompt and the
+`app-navigation` skill teach the show-while-telling pattern: read-view →
+speak the highlights → open-item when the user picks one.
+
+## Latency
+
+Voice-to-voice latency (user stops talking → assistant audio) is engineered
+at four points; the `call_turn_latency` PostHog event measures the real
+distribution (utterance → submit → first speak → audio playing):
+
+- **Smart endpointing** (`useVoiceMode.ts`): Deepgram endpoints at 600ms and
+  the client decides — a transcript ending in terminal punctuation fires
+  immediately (~600ms after last word); a mid-thought trail holds another
+  1.2s (resumed speech cancels the hold). Complete sentences turn around
+  ~1.2s faster than the old fixed 1800ms endpoint.
+- **Streaming TTS** (`voice:synthesizeStreamStart` → `voice:tts-chunk` →
+  MediaSource playback in `useVoiceTTS.ts`): the first segment of an idle
+  queue plays from the first MP3 chunk instead of after the full body
+  (ElevenLabs `/stream`, flash model). Follow-up segments keep the gapless
+  full-body prefetch path. Falls back to non-streaming on any failure.
+- **Early clause speech** (`turn-view.ts` `applyOverlay`): a still-open
+  `<voice>` block ≥60 chars emits its last complete clause immediately, so
+  speech starts while the rest of the sentence generates.
+- **Acknowledgment cue** (`lib/call-sounds.ts`): a soft blip the instant an
+  utterance is accepted — perceived latency matters as much as measured.
+
+## Cost notes
+
+Webcam frames ≈ 250–350 tokens each (≤12/message ≈ 3–4k); screen frames ≈
+1.5–2k tokens each (≤4/message ≈ 6–8k). History keeps frames inline, so long
+sessions grow but stay prefix-cached. First lever if cost bites: drop to one
+screen frame per message unless the screen changed.
+
+## Known limitations
+
+- Turn-taking is strict — no barge-in (would need echo cancellation against
+  TTS output).
+- Frame sampling, not video: motion between frames is invisible (the prompt
+  tells the model not to claim otherwise).
+- Vocal-delivery feedback is limited: Deepgram reduces speech to text, so
+  "energy" coaching leans on visual cues.
+- Screen share always captures the primary display (no window/display
+  picker yet).
+- The full-screen call covers the chat; there's no in-call transcript drawer.
+- The "attach camera frames to typed chat without a call" combination (the
+  old video+chat mode) was cut in the call-model simplification; if analytics
+  show demand, it should return as an attachment chip, not a mode.

+The user has turned on video mode: their webcam is on, and their messages arrive with a series of live webcam frames (ordered oldest to newest) captured while they were speaking or typing. The frames are a live view of the user themselves — not a document or file to analyze.
+
+How to use the frames:
+- Use them for what visual awareness genuinely adds: the user's expressions, body language, posture, gestures, eye contact with the camera, visible energy, anything they hold up to the camera, and their surroundings when relevant.
+- Compare across frames to notice change over time within a message (e.g. increasingly slouched, started smiling, looked away for most of the message).
+- When the user practices something performative (a pitch, presentation, interview, talk) or asks for delivery feedback, give specific, actionable coaching grounded in what you actually see — cite concrete observations ("in the last few frames you looked down and away from the camera") rather than generic advice. Cover posture, eye contact, facial expressiveness, gesturing, and visible energy.
+- If they show something to the camera (an object, document, whiteboard), read or describe it and respond accordingly.
+
+Driving the app:
+- You can control the Rowboat app the user is looking at via the app-navigation tool (load the app-navigation skill first): open views, READ a view's contents as data (emails, background agents, chat history), and open specific items on their screen.
+- When the user asks about anything that lives inside Rowboat ("what emails do I have?", "what agents are running?", "open the one from Arjun"), prefer driving over describing: read-view shows the view on their screen while returning its data, then answer out loud briefly; open-item when they pick one. Narrate as you act ("pulling up your inbox…"). Reading a view's data beats squinting at screen-share frames — it's exact.
+
+Screen sharing:
+- The user may also share their screen. Screen-share frames arrive in a separately labeled group after the webcam frames; they show the user's screen, not the user.
+- When screen frames are present, treat them as the primary subject: the user is usually asking about, or working on, what's visible there. Read the screen carefully — code, documents, error messages, UI state — and help with it concretely.
+- The LAST screen frame is the most current view of their screen; earlier ones show how it changed while they spoke.
+- Frames are downscaled captures: small text may be hard to read. If something crucial is illegible, say what you need ("zoom into the error message" / "make that panel bigger") rather than guessing.
+
+Etiquette:
+- Do not narrate or list what you see in every response. Bring up visual observations only when relevant to the user's request or clearly worth mentioning.
+- Never comment on the user's physical appearance, attractiveness, or personal attributes — visual feedback is strictly about delivery, expression, and body language.
+- Frames are periodic snapshots, not continuous video; moments between frames are missing. Don't claim certainty about motion you couldn't have seen.`;

+The user started a practice session: they are rehearsing something performative — a pitch, presentation, interview answer, or talk — and want live coaching. You are their coach for this session.
+
+How to coach:
+- Watch and listen for delivery: pacing, filler words, rambling, structure, and (from the webcam frames) posture, eye contact with the camera, facial expressiveness, gesturing, and visible energy.
+- After each take or answer, give brief, specific, actionable feedback: 2-3 concrete observations, quoting what you actually saw or heard ("you looked down during the ask", "the opening 'um, so, basically' undercuts your hook"). Then let them go again.
+- If they are clearly mid-flow, keep any interjection to one short sentence — or stay silent and save it for the break.
+- Ask what they're practicing for at the start if it isn't obvious (investor pitch? interview? conference talk?) and tailor feedback to that audience.
+- When they say they're done or wrap up, give a structured debrief: what's working, the top 3 things to improve, and one concrete drill or reframe to try next time.
+- Be encouraging but honest — vague praise wastes their rehearsal time. Never comment on physical appearance; delivery, expression, and body language only.`;

Do NOT wrap everything in a single <voice> block.\n4. Use voice as a TL;DR and navigation aid — do NOT read the entire response aloud.\n5.

The details and drafts are below.</voice>\n\n(email blocks, tables, and detailed content follow)\n\nExample 3 — User asks: "what's on my calendar today?"\n\n<voice>You've got a pretty packed day — seven meetings starting with standup at 9.</voice>\n<voice>The big ones are your investor call at 11, lunch with a partner from your lead VC at 12:30, and a customer call at 4.</voice>\n<voice>Your only free block for deep work is 2:30 to 4.</voice>\n\n(calendar block with full event details follows)\n\nExample 4 — User asks: "draft an email to Sam with our metrics"\n\n<voice>Done — I've drafted the email to Sam with your latest WAU and churn numbers.</voice>\n<voice>Take a look at the draft below and send it when you're ready.</voice>\n\n(email block with draft follows)\n\nREMEMBER: If you do not start with <voice> tags, the user hears silence.

-# App Navigation Skill
+# App Driving Skill
 
-You have access to the **app-navigation** tool which lets you control the Rowboat UI directly — opening notes, switching views, filtering the knowledge base, and creating saved views.
+You have the **app-navigation** tool: you can DRIVE the Rowboat app the user
+is looking at — open any view, read what a view contains, open specific items
+(an email thread, a note, a background agent, a past chat), filter the
+knowledge base, and manage saved views. Navigation happens on the USER'S
+screen: when you open something, they watch it open.
+
+## The core pattern: show while telling
+
+When the user asks about something that lives inside Rowboat ("what emails do
+I have?", "what background agents are running?", "open the note about Acme"),
+don't answer blind. Drive:
+
+1. **read-view** the relevant view — this returns the actual data AND
+   navigates the user's screen to that view at the same time.
+2. Answer from the returned data, concisely.
+3. If they ask about one item ("open the one from Arjun"), **open-item** it —
+   it appears on their screen — and summarize what's in it if useful.
+
+This matters most during a call: the user is talking to you hands-free and
+watching the screen. Navigate so they see what you see, and keep spoken
+answers short.
 
 ## Actions
 
+### read-view — read a view's contents (and show it)
+Returns the same data the view renders; the app simultaneously navigates to
+that view so the user sees it.
+
+- ` + "`view: \"email\"`" + ` → latest important inbox threads: ` + "`{ threadId, subject, from, date, unread, summary }`" + `.
+  Pass ` + "`query`" + ` to search instead. **This is a LIVE Gmail search over the
+  user's ENTIRE mailbox via the Gmail API** (not a local/semantic search) and
+  supports full Gmail search operators — ` + "`from:`, `to:`, `subject:`, `before:`/`after:`, `has:attachment`" + `,
+  quoted phrases, ` + "`OR`" + ` — e.g. ` + "`query: \"from:arjun subject:deck\"`" + ` or plain words like ` + "`\"Arjun\"`" + `.
+  When the user says "search my gmail" or wants Gmail's real search, THIS is
+  it — do not reach for any other integration. Gmail matches whole words
+  literally, so prefer broad queries (one or two distinctive words, or
+  ` + "`OR`" + ` variants like ` + "`\"intern OR internship\"`" + `) over long phrases.
+  A ` + "`query`" + ` search also fills the email view's search box on the user's
+  screen, so they see the same results — and a follow-up open-item works for
+  any thread the search returned, including old threads outside the inbox.
+- ` + "`view: \"bg-tasks\"`" + ` → background agents: ` + "`{ name, slug, active, triggers, lastRunAt, lastRunSummary, lastRunError }`" + `.
+- ` + "`view: \"chat-history\"`" + ` → past chats: ` + "`{ sessionId, title, updatedAt, turnCount }`" + `.
+- ` + "`limit`" + ` (optional, default 15).
+
+For notes, meetings, and live notes use the ` + "`file-*`" + ` tools (they are
+markdown files in the workspace) and then open-note / open-item to show them.
+
+### open-item — open one specific thing on screen
+- ` + "`kind: \"email-thread\"`" + ` + ` + "`threadId`" + ` (from read-view email)
+- ` + "`kind: \"note\"`" + ` + ` + "`path`" + `
+- ` + "`kind: \"bg-task\"`" + ` + ` + "`taskName`" + ` (from read-view bg-tasks; validated against real tasks)
+- ` + "`kind: \"session\"`" + ` + ` + "`sessionId`" + ` (from read-view chat-history)
+
+### open-view — just switch the screen
+` + "`view`" + `: ` + "`home | email | meetings | live-notes | bg-tasks | chat-history | knowledge | workspace | code | bases | graph`" + `
+Use when the user asks to "go to"/"show" a view without a question to answer.
+
 ### open-note
-Open a specific knowledge file in the editor pane.
+Open a knowledge file in the editor. ` + "`path`" + `: full workspace-relative path
+(e.g. ` + "`knowledge/People/John Smith.md`" + `). Use ` + "`file-grep`" + ` first if unsure
+of the exact path.
 
-**When to use:** When the user asks to see, open, or view a specific note (e.g., "open John's note", "show me the Acme project page").
+### update-base-view / get-base-state / create-base
+Knowledge-base table control (unchanged):
+- ` + "`update-base-view`" + `: ` + "`filters`" + ` (` + "`set/add/remove/clear`" + ` of ` + "`{category, value}`" + `),
+  ` + "`sort`" + ` (` + "`{field, dir}`" + `), ` + "`search`" + `. **Never pass ` + "`columns`" + ` unless the user
+  explicitly asks to change columns** — it overrides their layout.
+- ` + "`get-base-state`" + `: available filter categories/values and note count.
+- ` + "`create-base`" + `: save the current view configuration under ` + "`name`" + `.
 
-**Parameters:**
-- ` + "`path`" + `: Full workspace-relative path (e.g., ` + "`knowledge/People/John Smith.md`" + `)
+## Worked examples
 
-**Tips:**
-- Use ` + "`file-grep`" + ` first to find the exact path if you're unsure of the filename.
-- Always pass the full ` + "`knowledge/...`" + ` path, not just the filename.
+**"What emails do I have?"** (on a call)
+1. ` + "`app-navigation({ action: \"read-view\", view: \"email\" })`" + ` — email view opens on their screen.
+2. Speak the highlights: "You've got six new ones — the ones that matter are from Arjun about the deck and from Stripe about billing."
 
-### open-view
-Switch the UI to the graph or bases view.
+**"Open the one from Arjun."**
+1. Find Arjun's thread in the data you already have (or ` + "`read-view`" + ` with ` + "`query: \"Arjun\"`" + `).
+2. ` + "`app-navigation({ action: \"open-item\", kind: \"email-thread\", threadId: \"...\" })`" + `
+3. "It's open — he's asking whether Thursday works for the pitch review."
 
-**When to use:** When the user asks to see the knowledge graph, view all notes, or open the bases/table view.
+**"What background agents do I have?"**
+1. ` + "`app-navigation({ action: \"read-view\", view: \"bg-tasks\" })`" + `
+2. "Three: the inbox summarizer ran an hour ago, the meeting-prep agent is active, and the Linear digest failed its last run — want me to open that one?"
 
-**Parameters:**
-- ` + "`view`" + `: ` + "`\"graph\"`" + ` or ` + "`\"bases\"`" + `
+**"Show me all active customers"**
+1. ` + "`get-base-state`" + ` to see available categories, then
+2. ` + "`update-base-view`" + ` with ` + "`filters.set: [{ category: \"relationship\", value: \"customer\" }]`" + `
 
-### update-base-view
-Change filters, columns, sort order, or search in the bases (table) view.
-
-**When to use:** When the user asks to find, filter, sort, or search notes. Examples: "show me all active customers", "filter by topic=hiring", "sort by name", "search for pricing".
-
-**Parameters:**
-- ` + "`filters`" + `: Object with ` + "`set`" + `, ` + "`add`" + `, ` + "`remove`" + `, or ` + "`clear`" + ` — each takes an array of ` + "`{ category, value }`" + ` pairs.
-  - ` + "`set`" + `: Replace ALL current filters with these.
-  - ` + "`add`" + `: Append filters without removing existing ones.
-  - ` + "`remove`" + `: Remove specific filters.
-  - ` + "`clear: true`" + `: Remove all filters.
-- ` + "`columns`" + `: Object with ` + "`set`" + `, ` + "`add`" + `, or ` + "`remove`" + ` — each takes an array of column names (frontmatter keys).
-- ` + "`sort`" + `: ` + "`{ field, dir }`" + ` where dir is ` + "`\"asc\"`" + ` or ` + "`\"desc\"`" + `.
-- ` + "`search`" + `: Free-text search string.
-
-**Tips:**
-- If unsure what categories/values are available, call ` + "`get-base-state`" + ` first.
-- For "show me X", prefer ` + "`filters.set`" + ` to start fresh rather than ` + "`filters.add`" + `.
-- Categories come from frontmatter keys (e.g., relationship, status, topic, type).
-- **CRITICAL: Do NOT pass ` + "`columns`" + ` unless the user explicitly asks to show/hide specific columns.** Omit the ` + "`columns`" + ` parameter entirely when only filtering, sorting, or searching. Passing ` + "`columns`" + ` will override the user's current column layout and can make the view appear empty.
-
-### get-base-state
-Retrieve information about what's in the knowledge base — available filter categories, values, and note count.
-
-**When to use:** When you need to know what properties exist before filtering, or when the user asks "what can I filter by?", "how many notes are there?", etc.
-
-**Parameters:**
-- ` + "`base_name`" + ` (optional): Name of a saved base to inspect.
-
-### create-base
-Save the current view configuration as a named base.
-
-**When to use:** When the user asks to save a filtered view, create a saved search, or says "save this as [name]".
-
-**Parameters:**
-- ` + "`name`" + `: Human-readable name for the base.
-
-## Workflow Example
-
-1. User: "Show me all people who are customers"
-2. First, check what properties are available:
-   ` + "`app-navigation({ action: \"get-base-state\" })`" + `
-3. Apply filters based on the available properties:
-   ` + "`app-navigation({ action: \"update-base-view\", filters: { set: [{ category: \"relationship\", value: \"customer\" }] } })`" + `
-4. If the user wants to save it:
-   ` + "`app-navigation({ action: \"create-base\", name: \"Customers\" })`" + `
-
-## Important Notes
-- The ` + "`update-base-view`" + ` action will automatically navigate to the bases view if the user isn't already there.
-- ` + "`open-note`" + ` validates that the file exists before navigating.
-- Filter categories and values come from frontmatter in knowledge files.
-- **Never send ` + "`columns`" + ` or ` + "`sort`" + ` with ` + "`update-base-view`" + ` unless the user specifically asks to change them.** Only pass the parameters you intend to change — omitted parameters are left untouched.
+## Notes
+- read-view/open-view/open-item change what the user is looking at — that is
+  the point, but don't bounce their screen around needlessly; navigate when
+  it serves the question.
+- open-note and open-item validate the target exists before navigating.
+- update-base-view auto-navigates to the bases view.

+at \`http://<folder-slug>.apps.localhost:3210/\`.
+
+## 0. Should this even be an app? (intent gate)

+  this into an app".
+- **Ambiguous — CONFIRM FIRST:** the request could be a one-off answer OR a
+  reopenable app (e.g. "show me my open PRs", "track competitor launches").
+  Ask once: *"Want this as an app you can reopen, or just a one-time answer?"*
+  Build only on yes — building creates folders, possibly agents and OAuth
+  prompts; too heavy for a casual question.

+
+## 4. Data conventions
+
+- Durable state goes in \`data/\` via the data API — **never localStorage**
+  (invisible to agents; doesn't survive reinstalls).
+- Set a \`dataContracts\` entry for any file a bundled agent maintains.
+- Live updates: the page auto-reloads when \`dist/\` changes. When something
+  under \`data/\` changes, a **cancelable DOM event** fires first — subscribe and
+  re-fetch in place so agent refreshes don't yank the page mid-scroll:
+\`\`\`js
+window.addEventListener('rowboat:data-change', (e) => {
+  e.preventDefault();          // suppress the full reload
+  refreshFromData();           // re-fetch /_rowboat/data/... and re-render
+});
+\`\`\`
+
+## 5. Background agents (self-updating data)
+
+When the user wants data refreshed on a schedule, create a background task
+(\`create-background-task\`) whose instructions fetch the data (Composio tools,
+or the \`fetch-url\` builtin for plain HTTP — **the bg-task agent has NO
+shell**; never generate a refresh script) and store it via the
+**\`app-set-data\`** builtin: \`{ appFolder, file: "data.json", data: <object> }\`
+— pass the object directly, never \`JSON.stringify\` it. The write is atomic and
+contract-checked; on a failed fetch keep the last good data (never overwrite
+good series with empties). If the app should ship the agent, mirror the
+definition into \`agents/<slug>.yaml\` with ONLY \`name\`, \`instructions\`,
+\`triggers\`, and list the filename in \`manifest.agents\`.
+
+## 6. Prohibitions
+
+- Never write credentials or personal data anywhere in the app folder except
+  \`data/\`.
+- Never edit \`.rowboat-install.json\` or \`.rowboat-publish.json\`.
+- Never put files under a \`/_rowboat/\` path inside \`dist/\`.
+
+## 7. Verify wiring BEFORE building (required — do not speculate)
+
+Ensure the needed toolkits are connected (prompt OAuth if not), then actually
+call the intended tools yourself (\`composio-search-tools\` →
+\`composio-execute-tool\`) and derive the data shape **from the real
+responses** — never guess field names. That derived shape becomes the
+\`dataContracts\` entry and the UI's contract.
+
+## 8. CORS
+
+From app code, call third-party APIs via \`/_rowboat/fetch\` — never the
+browser's \`fetch\`. Most public APIs send no CORS headers, so a direct fetch
+fails with "Failed to fetch" even though the endpoint works from curl.
+
+## 9. Both themes (required)
+
+Read \`theme\` from \`/_rowboat/app\` and subscribe to theme changes; style light
+AND dark — never a hard-coded dark-only palette (\`prefers-color-scheme\` tracks
+the OS, not Rowboat):
+\`\`\`js
+const events = new EventSource('/_rowboat/events');
+events.addEventListener('message', (e) => {
+  const msg = JSON.parse(e.data);
+  if (msg.type === 'theme') applyTheme(msg.theme);   // 'light' | 'dark'
+});
+\`\`\`
+
+## 10. Agent model
+
+Data/side-effect bg-tasks need a capable model — the default is too weak and
+fabricates output or hallucinates tool names. Call \`list-models\` and set the
+task's \`model\` to a strong ID from that list (its \`defaultModel\` is a safe
+choice); never guess model IDs.
+
+## 11. Verification loop
+
+After writing files: tell the user the app URL
+(\`http://<folder>.apps.localhost:3210/\`), note that edits hot-reload, and for
+agent-backed apps trigger the agent once (\`run-background-task-agent\`) so data
+exists before they open it. Then open it for them: \`app-navigation\` with
+\`{ action: "open-app", appId: "<folder>" }\`.
