+#### Development Notes
+
+**API Client Generation**: After making changes to the TypeScript API endpoints in `packages/opencode/src/server/server.ts`, you need to regenerate the Go client and OpenAPI specification:
+
+```bash
+$ cd packages/tui
+$ go generate ./pkg/client/
+```
+
+This updates the generated Go client code that the TUI uses to communicate with the backend server.
