| **TranslationEngine** | 453 | 47 | 99% | Orchestrates all mappers |
---
## Common Patterns
### Bidirectional Conversion
All 3 adapters support:
- `toOAC()`: Tool format → OpenAgent
- `fromOAC()`: OpenAgent → Tool format
### Graceful Degradation
All adapters warn when features are lost:
- Granular permissions → Binary on/off
- Unsupported features → Warning messages
- Feature loss → Clear user notifications
### Type Safety
- All extend `BaseAdapter`
- Full TypeScript strict mode
- Zod schema validation
- 0 compilation errors
---
## Feature Parity Matrix
| Feature | OAC | Claude | Cursor | Windsurf |
|---------|-----|--------|--------|----------|
| Multiple Agents | ✅ | ✅ | ❌ | ✅ |
| Granular Permissions | ✅ | ❌ | ❌ | ❌ |
| Ask Permissions | ✅ | ❌ | ❌ | ❌ |
| Hooks | ✅ | ✅ | ❌ | ❌ |
| Skills | ✅ | ✅ | ❌ | ⚠️ |
| External Context | ✅ | ✅ | ❌ | ✅ |
| Context Priority | ✅ | ❌ | ❌ | ❌ |
| Temperature | ✅ | ❌ | ⚠️ | ✅ |
| Model Selection | ✅ | ✅ | ✅ | ✅ |
| Task Delegation | ✅ | ✅ | ❌ | ⚠️ |
Legend: ✅ Full support, ⚠️ Partial support, ❌ Not supported
