+# Analytics
+
+> PostHog instrumentation for `apps/x`. We capture LLM token usage (broken down by feature) and identity/auth events. Renderer (`posthog-js`) and main (`posthog-node`) share one stable distinct_id and one identified user, so events from either process resolve to the same person.
+
+## Identity model
+
+- **Anonymous distinct_id** = `installationId` from `~/.rowboat/config/installation.json` (auto-generated on first run; see `packages/core/src/analytics/installation.ts`).
+- Renderer fetches it from main on startup via the `analytics:bootstrap` IPC channel and passes it as PostHog's `bootstrap.distinctID`. Main uses it directly in `posthog-node`.
+- **On rowboat sign-in**: `posthog.identify(rowboatUserId)` runs in **both** processes.
+  - Main does it from `apps/main/src/oauth-handler.ts:285` (after `getBillingInfo()` resolves) — this is the load-bearing call, since main always runs.
+  - Renderer mirrors via `apps/renderer/src/hooks/useAnalyticsIdentity.ts` listening on the `oauth:didConnect` IPC event.
+  - Main also calls `alias()` so events emitted under the anonymous installation_id are linked to the identified user retroactively.
+- **On every app startup**: main re-identifies if rowboat tokens exist (`packages/core/src/analytics/identify.ts`, called from `apps/main/src/main.ts` whenReady). Idempotent — PostHog merges person properties on duplicate identifies. This catches users who installed before analytics existed, and refreshes person properties (plan/status) on every launch.
+- **On rowboat sign-out**: `posthog.reset()` in both processes; future events resolve to the installation_id again.
+- **`email`** is set on `identify` from main only (sourced from `/v1/me`). Person properties are server-side, so the renderer's events resolve to the same record without redundantly setting it.
+
+## Event catalog
+
+### `llm_usage`
+
+Emitted whenever ai-sdk returns token usage (one event per LLM call, not per run).
+
+| Property | Type | Notes |
+|---|---|---|
+| `use_case` | enum | `copilot_chat` / `track_block` / `meeting_note` / `knowledge_sync` |
+| `sub_use_case` | string? | Refines `use_case` — see taxonomy table below |
+| `agent_name` | string? | Present when the call goes through an agent run (`createRun`); omitted for direct `generateText`/`generateObject` |
+| `model` | string | e.g. `claude-sonnet-4-6` |
+| `provider` | string | `rowboat` = cloud LLM gateway; otherwise the BYOK provider (`openai`, `anthropic`, `ollama`, etc.) |
+| `input_tokens` | number | |
+| `output_tokens` | number | |
+| `total_tokens` | number | |
+| `cached_input_tokens` | number? | When the provider reports it |
+| `reasoning_tokens` | number? | When the provider reports it |
+
+#### Use-case taxonomy
+
+Every `llm_usage` emit point in the codebase:
+
+| `use_case` | `sub_use_case` | `agent_name`? | Where | File:line |
+|---|---|---|---|---|
+| `copilot_chat` | (none) | yes | User chat in renderer (default for any `createRun` without `useCase`) | `packages/core/src/agents/runtime.ts:1313` (finish-step in `streamLlm`) |
+| `copilot_chat` | `scheduled` | yes | Background scheduled agent runner | `packages/core/src/agent-schedule/runner.ts:167` |
+| `copilot_chat` | `file_parse` | inherits | `parseFile` builtin tool inside any chat | `packages/core/src/application/lib/builtin-tools.ts:770` |
+| `track_block` | `routing` | no | Pass 1 routing classifier (`generateObject`) | `packages/core/src/knowledge/track/routing.ts:104` |
+| `track_block` | `run` | yes | Pass 2 track block execution | `packages/core/src/knowledge/track/runner.ts:109` (createRun) |
+| `meeting_note` | (none) | no | Meeting transcript summarizer (`generateText`) | `packages/core/src/knowledge/summarize_meeting.ts:161` |
+| `knowledge_sync` | `agent_notes` | yes | Agent notes learning service | `packages/core/src/knowledge/agent_notes.ts:309` (createRun) |
+| `knowledge_sync` | `tag_notes` | yes | Note tagging | `packages/core/src/knowledge/tag_notes.ts:86` (createRun) |
+| `knowledge_sync` | `build_graph` | yes | Knowledge graph note creation | `packages/core/src/knowledge/build_graph.ts:253` (createRun) |
+| `knowledge_sync` | `label_emails` | yes | Email labeling | `packages/core/src/knowledge/label_emails.ts:73` (createRun) |
+| `knowledge_sync` | `inline_task_run` | yes | Inline `@rowboat` task execution (two call sites) | `packages/core/src/knowledge/inline_tasks.ts:471, 552` (createRun) |
+| `knowledge_sync` | `inline_task_classify` | no | Inline task scheduling classifier (`generateText`) | `packages/core/src/knowledge/inline_tasks.ts:673` |
+| `knowledge_sync` | `pre_built` | yes | Pre-built scheduled agents | `packages/core/src/pre_built/runner.ts:43` (createRun) |
+
+`testModelConnection` in `packages/core/src/models/models.ts` is **not** instrumented (diagnostic only — would skew per-model counts).
+
+### `user_signed_in`
+
+Emitted when rowboat OAuth completes. Properties: `plan`, `status` (subscription state from `/v1/me`).
+
+Emitted from **both** processes:
+- Main (`apps/main/src/oauth-handler.ts:290`) — always fires; load-bearing.
+- Renderer (`apps/renderer/src/hooks/useAnalyticsIdentity.ts:75`) — fires only when the renderer is open. Same distinct_id, so dedup is automatic in PostHog dashboards.
+
+### `user_signed_out`
+
+Emitted on rowboat disconnect. No properties. Followed immediately by `posthog.reset()`.
+
+Emit points: `apps/main/src/oauth-handler.ts:369` and `apps/renderer/src/hooks/useAnalyticsIdentity.ts:82`.
+
+### Other events (pre-existing, not added by the LLM-usage work)
+
+All in `apps/renderer/src/lib/analytics.ts`:
+
+- `chat_session_created` — `{ run_id }`
+- `chat_message_sent` — `{ voice_input, voice_output, search_enabled }`
+- `oauth_connected` / `oauth_disconnected` — `{ provider }`
+- `voice_input_started` — no properties
+- `search_executed` — `{ types: string[] }`
+- `note_exported` — `{ format }`
+
+## Person properties
+
+Persistent across sessions for the same user. Set via `posthog.people.set` or as the `properties` arg to `identify`.
+
+| Property | Set by | Notes |
+|---|---|---|
+| `email` | main on identify | From `/v1/me`; powers PostHog cohort match + integrations |
+| `plan`, `status` | main on identify | Subscription state |
+| `api_url` | both processes (init + identify) | Distinguishes prod / staging / custom — assign meaning in PostHog dashboard. `https://api.x.rowboatlabs.com` = production |
+| `signed_in` | renderer | `true` while rowboat OAuth is connected |
+| `{provider}_connected` | renderer | One of `gmail`, `calendar`, `slack`, `rowboat` |
+| `total_notes` | renderer (init) | Workspace size signal |
+| `has_used_search`, `has_used_voice` | renderer | One-shot first-use flags |
+
+## How to add a new event
+
+1. **Naming**: `snake_case`, `[object]_[verb]` shape (e.g. `note_exported`, not `exportedNote`). Matches PostHog convention.
+2. **Pick the right helper**:
+   - LLM token usage → `captureLlmUsage()` from `@x/core/dist/analytics/usage.js`. Always include `useCase`; add `subUseCase` if it refines an existing top-level case.
+   - Anything else from main → `capture()` from `@x/core/dist/analytics/posthog.js`.
+   - Anything else from renderer → add a typed wrapper to `apps/renderer/src/lib/analytics.ts` and call it from the UI code (don't call `posthog.capture()` directly from components).
+3. **If it's a new LLM call site**:
+   - Goes through `createRun`? Pass `useCase` (and optionally `subUseCase`) to the create call. The runtime auto-emits at every `finish-step` — no further code needed.
+   - Direct `generateText` / `generateObject`? Call `captureLlmUsage` after the call with `model`, `provider`, `usage` from the result.
+   - Inside a builtin tool? Call `getCurrentUseCase()` from `analytics/use_case.ts` first — the parent run's tag is propagated via `AsyncLocalStorage`. Use `ctx?.useCase ?? 'copilot_chat'` as fallback.
+4. **Update this file in the same PR.** That's the contract — without it, dashboards and downstream consumers drift.
+
+## How to add a new use-case sub-case
+
+- **New `sub_use_case` under an existing top-level case**: just pick a string and add a row to the taxonomy table above. No code changes beyond the call site.
+- **New top-level `use_case`**: edit the `UseCase` enum in `packages/shared/src/runs.ts` and the matching `UseCase` type in `packages/core/src/analytics/use_case.ts`. Then update this doc.
+
+## Configuration
+
+PostHog credentials live in two env vars (also baked into the binary at packaging time — never set at runtime in distributed builds):
+
+- `VITE_PUBLIC_POSTHOG_KEY` — project API key (e.g. `phc_xxx`). Public-facing — safe to commit if you'd rather hardcode.
+- `VITE_PUBLIC_POSTHOG_HOST` — e.g. `https://us.i.posthog.com`. Defaults to US cloud if unset.
+
+Where they're consumed:
+- **Renderer** (Vite): `import.meta.env.VITE_PUBLIC_POSTHOG_*` — inlined at build time.
+- **Main** (esbuild via `apps/main/bundle.mjs`): inlined into `main.cjs` at packaging time using esbuild `define`. In dev (`npm run dev`), main reads them from `process.env` at runtime.
+
+For GitHub Actions / packaged builds: set both as workflow env vars (from secrets) on the step that runs `npm run package` or `npm run make`. They'll be baked in.
+
+If unset, analytics no-op silently — you'll see `[Analytics] POSTHOG_KEY not set; analytics disabled` in main-process logs.
+
+`installationId`: stored in `~/.rowboat/config/installation.json`, generated on first run.

+## Do Not Set ` + "`" + `model` + "`" + ` or ` + "`" + `provider` + "`" + ` (almost always)
+
+The schema includes optional ` + "`" + `model` + "`" + ` and ` + "`" + `provider` + "`" + ` fields. **Omit them.** A user-configurable global default already picks the right model and provider for tracks; setting per-track values bypasses that and is almost always wrong.
+
+The only time these belong on a track:
+
+- The user **explicitly** named a model or provider for *this specific track* in their request ("use Claude Opus for this one", "force this track onto OpenAI"). Quote the user's wording back when confirming.
+
+Things that are **not** reasons to set these:
+
+- "Tracks should be fast" / "I want a small model" — that's a global preference, not a per-track one. Leave it; the global default exists.
+- "This track is complex" — write a clearer instruction; don't reach for a different model.
+- "Just to be safe" / "in case it matters" — this is the antipattern. Leave them out.
+- The user changed their main chat model — that has nothing to do with tracks. Leave them out.
+
+When in doubt: omit both fields. Never volunteer them. Never include them in a starter template you suggest. If you find yourself adding them as a sensible default, stop — you're wrong.

+- Start time is later this morning or this afternoon → upcoming: name the meeting and roughly when (e.g. "Design review later this morning." / "1:1 with Sam this afternoon.").
+- Start time is several hours out or nothing before then → focus block: frame the gap (e.g. "Next up is the all-hands at 3pm — good long focus block until then.").
 
-Lead based on how soon the next event is:
+Use the event's start time of day ("at 3pm", "this afternoon") rather than a countdown ("in 40 minutes"). Countdowns go stale between syncs.
-- Under 15 minutes → urgent ("Standup starts in 10 minutes — join link in the Calendar section below.")

+Data: read today's events from calendar_sync/ (workspace-readdir, then workspace-readFile each .json file). Filter to events whose start datetime is today and hasn't ended yet — for finding the next event, pick the earliest upcoming one; if all have passed, treat as clear.
 
 If you find quick context in knowledge/ that's genuinely useful, add one short clause ("Ramnique pushed the OAuth PR yesterday — might come up"). Use workspace-grep / workspace-readFile conservatively; don't stall on deep research.

If it's marketing, an auto-notification, a thread already closed out, or otherwise low-signal, skip the update — do NOT call update-track-content.

+Event-driven path (primary): the agent message will include a "Gmail sync update" digest payload describing one or more freshly-synced threads from a single sync run. The digest lists each thread with its subject, sender, date, threadId, and body. Iterate over every thread in the payload and decide per thread whether it warrants surfacing. Skip marketing, auto-notifications, closed-out threads, and other low-signal mail. For threads that are attention-worthy, integrate them into the existing digest: add a new email block for a new threadId, or update the existing block if the threadId is already shown. If NONE of the threads in the payload are attention-worthy, skip the update — do NOT call update-track-content. Emit at most one update-track-content call that covers the full set of changes from this event.
 
 Manual path (fallback): with no event payload, scan gmail_sync/ via workspace-readdir (skip sync_state.json and attachments/). Read threads with workspace-readFile. Prioritize threads whose frontmatter action field is "reply" or "respond", plus other high-signal recent threads.
