+# Development Commands
+
+**Environment Setup:**
+```bash
+bun install                    # Install dependencies
+mkdir -p src-tauri/resources/models
+curl -o src-tauri/resources/models/silero_vad_v4.onnx https://blob.handy.computer/silero_vad_v4.onnx
+```
+
+**Development:**
+```bash
+bun run tauri dev              # Full app development
+CMAKE_POLICY_VERSION_MINIMUM=3.5 bun run tauri dev  # macOS with cmake fix
+bun run dev                     # Frontend only (Vite)
+bun run build                   # Build frontend
+bun run tauri build             # Production build
+```
+
+**Type Check & Build:**
+```bash
+bunx tsc --noEmit               # Type checking  
+bun run build                   # Build and validate
+```
+
+# Code Style Guidelines
+
+**Rust (Backend):**
+- Use `anyhow::Error` for error handling with descriptive messages
+- Prefer `Arc<Mutex<T>>` for shared state in managers
+- Log with appropriate levels: `debug!`, `info!`, `eprintln!` for errors
+- Builder pattern for initialization chains
+- Snake_case for functions and variables, PascalCase for types
+- Separate logical sections with comment blocks: `/* ─────────── */`
+
+**TypeScript/React (Frontend):**
+- Functional components with TypeScript interfaces
+- Zod schemas for type validation and inference
+- `useCallback` hooks for stable function references
+- Destructure props with defaults: `disabled = false`
+- Prefer interface aliases over type aliases for objects
+- React.FC for explicit component typing
+- PascalCase for components, camelCase for variables/functions
+
+**Imports:**
+- Group imports: external libs, internal modules, relative imports
+- Use type imports for TypeScript: `import type { Settings }`
+- Named imports preferred over default exports
+
+**Error Handling:**
+- Frontend: Try/catch with user feedback, rollback optimistic updates
+- Backend: `?` operator with anyhow context messages
+- Log errors appropriately for debugging level
+
+**Component Patterns:**
+- Container component pattern for layout
+- Composition over inheritance
+- Prop drilling minimized with context where appropriate
