Capture screen recordings as video files attached to the conversation.

## Activation

The user asks to start, stop, pause, resume, or restart a screen recording.
Routing does not depend on matching phrases: see Routing below.

## Routing

Recording is managed through dedicated HTTP endpoints (`/v1/recordings/*`) rather than text-based intent detection. Two routing mechanisms exist:

### 1. `commandIntent` (structured command) - highest priority

The macOS client can send structured intents with `domain: 'screen_recording'` and `action: 'start' | 'stop' | 'restart' | 'pause' | 'resume'`. These bypass text parsing entirely. The assistant checks for `commandIntent` before any text analysis.

### 2. HTTP endpoints

Clients call the recording HTTP endpoints directly:

- `POST /v1/recordings/start` - start a screen recording
- `POST /v1/recordings/stop` - stop the active recording
- `POST /v1/recordings/pause` - pause the active recording
- `POST /v1/recordings/resume` - resume a paused recording
- `GET /v1/recordings/status` - get current recording status
- `POST /v1/recordings/status` - recording lifecycle callback from the client

### 3. Normal processing

If no recording intent is detected, the message flows to the classifier and computer-use session as usual.

## Behavior Rules

1. **Do not invoke computer use** for recording-only requests. The assistant handles these directly.
2. **One recording at a time.** If a recording is already active, starting another returns an "already recording" message.
3. **Conversation-linked.** Each recording is linked to the conversation that started it for attachment purposes. However, since only one recording can be active at a time, stop commands from any conversation will stop the active recording regardless of which conversation started it.
4. **Permission required.** Screen recording requires macOS Screen Recording permission. If denied, the user sees actionable guidance to enable it in System Settings.
5. **Mixed-intent prompts** (recording + other task) are NOT intercepted by the standalone route - the recording action is deferred and executed alongside the task.
6. **Restart always reopens the source picker** and requires source reselection.
7. **Restart cancel** (user closes the source picker) leaves state idle - no false "recording started" message.
8. **Pause/resume toggle the recording** without stopping it. The HUD shows paused state.

## What This Skill Does NOT Do

- This skill does not contain recorder logic - the `RecordingManager` and `ScreenRecorder` in the macOS app handle the actual recording.
- This skill does not provide shell commands or scripts for recording.
- This skill does not fall back to computer use for recording tasks.
- This skill does not handle informational questions about recording - those flow through to normal AI response.
