- Tool use visualization
- Auto-scroll behavior

### Task 007: Prompt Input
- Text input with multi-line support
- Send button
- File attachment support
- Keyboard shortcuts (Enter for new line; Cmd+Enter/Ctrl+Enter to send)

### Task 008: Instance Tabs

## Build & Test

```bash
cd packages/opencode-client
bun run build
bunx electron .
```

**Known Issue:**
- Dev mode (`bun dev`) fails due to Bun workspace hoisting + electron-vite
- Workaround: Use production builds for testing

## Dependencies

- Electron 38
- SolidJS 1.8
- TailwindCSS 3.x
- @opencode-ai/sdk
- @kobalte/core (Dialog)
- Vite 5
- TypeScript 5
