# ✅ Claude OAuth - Complete and Ready!

**Date:** 2026-03-09  
**Status:** ✅ **READY TO USE**

## What's Done

### ✅ Backend (Automated Token Generation)
- `ClaudeSetupTokenService` - CLI installation + token generation
- `auth:claude:start-oauth` - Automated setup IPC handler
- `auth:claude:paste-token` - Manual fallback
- Token storage (encrypted, 1-year validity)

### ✅ Frontend (Already Exists!)
- `OAuthSection` component - Handles OAuth UI
- `useOAuth` hook - Manages OAuth state
- Settings page - Claude OAuth section already displayed
- Preload script - API exports configured

## How To Use

### For Users

1. **Open Settings** (gear icon or ⌘+,)
2. **Go to "API Keys" tab**
3. **Find "Claude" OAuth section**
4. **Click "Sign in with Claude"**
5. **Browser opens** for OAuth authentication
6. **Sign in and authorize**
7. **Done!** Token automatically saved

## Key Files

### Backend
- `src/core/services/ClaudeSetupTokenService.ts` - Token generation
- `src/electron/ipc/oauth.ts` - IPC handlers
- `src/core/storage/OAuthTokenStorage.ts` - Token storage

### Frontend
- `ui/components/Settings/OAuthSection.tsx` - OAuth UI component

- `src/electron/preload.cjs` - API exports

## What's Different from OpenAI OAuth?

| Feature | OpenAI | Claude |
|---------|--------|--------|
| **Method** | Full OAuth flow | Automated CLI token |
| **Callback** | Local server (port 1455) | CLI handles it |
| **Installation** | None needed | Auto-installs CLI |
| **Token Format** | `oat_...` | `sk-ant-oat01-...` |
| **Validity** | Short-lived | 1 year |
| **Refresh** | ✅ Automatic | ❌ Must regenerate |
| **User Flow** | Click → Authorize | Click → Authorize (same!) |

## Benefits

1. ✅ **One-Click Experience** - No manual CLI commands
2. ✅ **Automatic CLI Installation** - Just works
3. ✅ **Token Auto-Extraction** - No copy-paste
4. ✅ **Long-Lived Tokens** - 1 year validity
5. ✅ **Encrypted Storage** - Secure
6. ✅ **Manual Fallback** - Paste token if needed
7. ✅ **Same as OpenClaw** - Proven approach

## Known Limitations

1. **Requires npm** - CLI installation needs npm
2. **No Token Refresh** - Must regenerate after 1 year
3. **CLI Dependency** - Needs @anthropic-ai/claude-code
4. **5-Minute Timeout** - User must complete OAuth quickly

## Troubleshooting

### "Failed to install Claude CLI"
**Solution:** Install manually then retry:
```bash
npm install -g @anthropic-ai/claude-code
```

### "Token generation timed out"
**Solution:** Complete OAuth within 5 minutes, or use manual paste

### "Could not extract token"
**Solution:** Manual fallback:
1. Run: `claude setup-token`
2. Copy the displayed token
3. Click "Paste Token Manually" in Settings
4. Paste and save

### Connection works but chat fails
**Check:** Make sure you selected a Claude model in the chat

## Success Criteria

✅ User can click one button to connect  
✅ CLI installs automatically if needed  
✅ Browser opens for OAuth  
✅ Token extracted and saved automatically  
✅ UI shows connection status  
✅ Claude models work with subscription  
✅ Token persists across app restarts  
✅ Can disconnect and reconnect

## 🎉 Ready to Use!

Everything is implemented and ready. Users can now:

1. Open Settings
2. Click "Sign in with Claude"
3. Authorize in browser
4. Start using Claude with their subscription!

**No additional UI work needed - it's all done!**
