How It Works

1. User Types - Debounced event (300ms default)
2. Get Code Context - Captures text before cursor
3. Check Cache - Returns cached result if available
4. API Call - Sends request to Cursor's StreamCpp endpoint
5. Protobuf Encode - Encodes request in binary format
6. HTTPS POST - Sends request to Cursor API
7. Stream Response - Decodes streamed chunks
8. Show Completion - Displays inline suggestion
9. Cache Result - Stores result for future use

Troubleshooting

No completions showing

• Check status bar icon (bottom right)
• Verify credentials are configured
• Check Output panel: "Cursor Suggest"

Warning icon in status bar

• Missing API credentials
• Run: Cursor Suggest: Configure API Keys

API errors

• Bearer token may be expired - get new credentials from Cursor
• Session ID may have changed - reconfigure credentials

Privacy & Security

• Your code is sent to Cursor's API for completion generation
• API credentials are stored locally in VS Code settings
• No data is stored or logged by this extension
• Please review Cursor's privacy policy for their data handling
