+# Deeplink + Raycast Extension Implementation
+
+This document describes the implementation of issue #1540: Extended deeplinks and Raycast extension for Cap.
+
+## Changes Made
+
+### 1. Extended Deeplink Actions
+
+**File:** `apps/desktop/src-tauri/src/deeplink_actions.rs`
+
+Added four new deeplink actions to the `DeepLinkAction` enum:
+
+```rust
+pub enum DeepLinkAction {
+    // ... existing actions ...
+    PauseRecording,
+    ResumeRecording,
+    ToggleMicrophone,
+    ToggleCamera,
+}
+```
+
+#### Implementation Details
+
+**PauseRecording**
+- Calls `crate::recording::pause_recording()`
+- Pauses the current active recording
+- URL: `cap-desktop://action?value={"pause_recording":null}`
+
+**ResumeRecording**
+- Calls `crate::recording::resume_recording()`
+- Resumes a paused recording
+- URL: `cap-desktop://action?value={"resume_recording":null}`
+
+**ToggleMicrophone**
+- Reads current microphone state from app state
+- If microphone is enabled, disables it by calling `set_mic_input(None)`
+- If microphone is disabled, returns an error (cannot enable without knowing which mic to use)
+- URL: `cap-desktop://action?value={"toggle_microphone":null}`
+
+**ToggleCamera**
+- Reads current camera state from app state
+- If camera is enabled, disables it by calling `set_camera_input(None)`
+- If camera is disabled, returns an error (cannot enable without knowing which camera to use)
+- URL: `cap-desktop://action?value={"toggle_camera":null}`
+
+#### Toggle Behavior Note
+
+The toggle commands implement a "disable-only" toggle pattern:
+- ✅ Can disable an active camera/microphone
+- ❌ Cannot re-enable without device specification
+
+This is intentional because:
+1. The system needs to know **which** camera/microphone to enable
+2. Users may have multiple devices
+3. Starting a recording with specific devices is better handled through `StartRecording` action
+
+For enabling camera/microphone, users should use the existing `StartRecording` action with explicit device parameters.
+
+### 2. Raycast Extension
+
+**Directory:** `raycast-extension/`
+
+Created a complete Raycast extension with the following structure:
+
+```
+raycast-extension/
+├── package.json          # Extension manifest and dependencies
+├── tsconfig.json         # TypeScript configuration
+├── README.md            # Usage documentation
+├── .gitignore           # Git ignore rules
+├── ICON_NOTE.md         # Icon requirements
+└── src/
+    ├── utils.ts                  # Shared deeplink execution utility
+    ├── start-recording.tsx       # Start recording command
+    ├── stop-recording.tsx        # Stop recording command
+    ├── pause-recording.tsx       # Pause recording command
+    ├── resume-recording.tsx      # Resume recording command
+    ├── toggle-microphone.tsx     # Toggle microphone command
+    └── toggle-camera.tsx         # Toggle camera command
+```
+
+#### Commands Implemented
+
+1. **Stop Recording** - Stops the current recording
+2. **Pause Recording** - Pauses the active recording
+3. **Resume Recording** - Resumes the paused recording
+4. **Toggle Microphone** - Toggles microphone on/off
+5. **Toggle Camera** - Toggles camera on/off
+6. **Start Recording** - Opens Cap app (simplified for now)
+
+#### How It Works
+
+Each command:
+1. Closes the Raycast window (`closeMainWindow()`)
+2. Constructs a deeplink URL with JSON-encoded action
+3. Executes `open "cap-desktop://action?value=..."` via shell
+4. Shows toast notification for feedback
+
+Example deeplink execution:
+```typescript
+const action = { stop_recording: null };
+const url = `cap-desktop://action?value=${encodeURIComponent(JSON.stringify(action))}`;
+await execAsync(`open "${url}"`);
+```
+
+## Testing
+
+### Test Deeplinks Manually
+
+You can test deeplinks directly from Terminal:
+
+```bash
+# Stop recording
+open "cap-desktop://action?value=%7B%22stop_recording%22%3Anull%7D"
+
+# Pause recording
+open "cap-desktop://action?value=%7B%22pause_recording%22%3Anull%7D"
+
+# Resume recording
+open "cap-desktop://action?value=%7B%22resume_recording%22%3Anull%7D"
+
+# Toggle microphone
+open "cap-desktop://action?value=%7B%22toggle_microphone%22%3Anull%7D"
+
+# Toggle camera
+open "cap-desktop://action?value=%7B%22toggle_camera%22%3Anull%7D"
+```
+
+### Test Raycast Extension
+
+1. Install dependencies:
+   ```bash
+   cd raycast-extension
+   npm install
+   ```
+
+2. Run in development mode:
+   ```bash
+   npm run dev
+   ```
+
+3. Import in Raycast and test each command
+
+### Test Scenarios
+
+1. **Happy Path**
+   - Start a recording in Cap
+   - Use Raycast to pause → resume → stop
+   - Verify each action works correctly
+
+2. **Toggle Commands**
+   - Start recording with camera and mic
+   - Toggle microphone off → verify mic disabled
+   - Toggle camera off → verify camera disabled
+   - Attempt to toggle back on → should show error message
+
+3. **Error Handling**
+   - Try to pause when no recording is active
+   - Try to resume when not paused
+   - Verify appropriate error messages
+
+## Dependencies Used
+
+### Existing Functions
+All new deeplink actions use existing Cap functions:
+- `recording::pause_recording()` - Already implemented
+- `recording::resume_recording()` - Already implemented  
+- `set_mic_input()` - Already implemented
+- `set_camera_input()` - Already implemented
+
+### Raycast API
+- `@raycast/api` v1.48.0
+- `closeMainWindow()` - Close Raycast UI
+- `showToast()` - Show notifications
+- Node.js `child_process.exec` - Execute shell commands
+
+## Future Enhancements
+
+1. **Enhanced Start Recording**
+   - Add Raycast form to select screen/window
+   - Configure camera and microphone
+   - Choose recording mode (Studio/Instant)
+
+2. **Stateful Toggles**
+   - Store last-used camera/microphone in preferences
+   - Allow toggle-on to restore previous device
+
+3. **Status Display**
+   - Show current recording status in menu bar
+   - Display recording duration
+   - Show which devices are active
+
+4. **Quick Actions**
+   - Recent recordings list
+   - Quick share to clipboard
+   - Open in editor
+
+## Pull Request Checklist

+# Cap Raycast Extension
+
+Control your Cap screen recordings directly from Raycast with keyboard shortcuts.
+
+## Features
+
+- 🎥 **Stop Recording** - Stop your current recording
+- ⏸️ **Pause Recording** - Pause your active recording  
+- ▶️ **Resume Recording** - Resume your paused recording
+- 🎤 **Toggle Microphone** - Toggle microphone on/off during recording
+- 📷 **Toggle Camera** - Toggle camera on/off during recording
+- 🎬 **Start Recording** - Quick access to start a new recording (opens Cap app)
+
+## Installation
+
+1. Install the Raycast extension:
+   ```bash
+   cd raycast-extension
+   npm install
+   npm run dev
+   ```
+
+2. Import the extension in Raycast
+
+3. Set up keyboard shortcuts for each command in Raycast preferences
+
+## How It Works
+
+This extension uses Cap's deeplink URL scheme (`cap-desktop://`) to control recordings. Each command sends a deeplink action to Cap, which executes the corresponding function.
+
+### Available Deeplink Actions
+
+- `stop_recording` - Stops the current recording
+- `pause_recording` - Pauses the current recording
+- `resume_recording` - Resumes a paused recording
+- `toggle_microphone` - Toggles the microphone (disables if enabled)
+- `toggle_camera` - Toggles the camera (disables if enabled)
+
+### URL Format
+
+```
+cap-desktop://action?value=<JSON-encoded-action>
+```
+
+Example:
+```
+cap-desktop://action?value=%7B%22stop_recording%22%3Anull%7D
+```
+
+## Usage
+
+1. Start a recording in Cap (use the main app or your configured shortcuts)
+2. Use Raycast commands to control the recording:
+   - `Stop Recording` - End and save your recording
+   - `Pause Recording` - Temporarily pause recording
+   - `Resume Recording` - Continue recording after pause
+   - `Toggle Microphone` - Disable microphone (toggle on requires mic selection)
+   - `Toggle Camera` - Disable camera (toggle on requires camera selection)
+
+## Notes
+
+- **Toggle Limitations**: The toggle commands can disable camera/microphone, but cannot re-enable them without knowing which device to use. To re-enable, start a new recording with the desired devices.
+- **Start Recording**: For starting a recording with specific settings (screen, window, camera, mic), use the Cap app directly. The Raycast commands are best for controlling active recordings.
+
+## Development
+
+```bash
+# Install dependencies
+npm install
+
+# Start development mode
+npm run dev
+
+# Build for production  
+npm run build
+
+# Lint and fix
+npm run fix-lint
+```
+
+## Requirements
+
+- Cap desktop app installed
+- macOS with Raycast installed
+- Cap deeplink handler registered (`cap-desktop://` URL scheme)
+
+## Icon
+
+The extension requires a `command-icon.png` file. Use the Cap logo or create a custom icon (512x512px recommended).
