## Features Implemented

### Security & Filtering
- ✅ Agent loop prevention
- ✅ Quiet hours (23:00-07:00)
- ✅ Agent mapping per microDAO
- ✅ Channel allowlists
- ✅ Disabled agents support

### Routing
- ✅ Filter decision processing
- ✅ Agent invocation creation
- ✅ Configurable rules
- ✅ Error handling

### Agent Execution

---

## Known Limitations (By Design)

### Phase 2 Scope:
- ✅ Mock LLM responses (keyword-based)
  - **Reason:** Real LLM in Phase 3
  - **Impact:** Limited response variety
  - **Mitigation:** Keywords cover common cases

- ✅ Mock agent blueprints
  - **Reason:** Blueprint service in Phase 3
  - **Impact:** Single agent personality
  - **Mitigation:** Sofia-Prime works well

- ✅ Optional memory service
  - **Reason:** Memory service in Phase 3
  - **Impact:** No long-term context
  - **Mitigation:** Channel history sufficient
