3. `POST /api/command/deleteAgent` - Soft delete agents
4. `POST /api/command/createConversation` - Returns `{id: guid}`
5. `POST /api/command/startAgentExecution` - Returns `{id: guid}`
6. `POST /api/command/completeAgentExecution` - Track completion

**Queries (4)**:
7. `POST /api/query/health` - Health check
8. `POST /api/query/getAgent` - Get single agent
9. `POST /api/query/getAgentExecution` - Get execution details
10. `POST /api/query/getConversation` - Get conversation with messages

**Lists (6)**:
11. `GET /api/agents` - List all agents
12. `GET /api/conversations` - List all conversations
13. `GET /api/executions` - List all executions
14. `GET /api/agents/{id}/conversations` - Agent conversations
15. `GET /api/agents/{id}/executions` - Agent execution history
16. `GET /api/executions/status/{status}` - Filter by status

### Security Features
- ✅ AES-256 encryption for API keys
- ✅ FluentValidation on all commands
- ✅ Global exception middleware
- ✅ Rate limiting (1000 req/min)
- ✅ SQL injection prevention (EF Core parameterized queries)

### Documentation
- ✅ `docs/COMPLETE-API-REFERENCE.md` - All endpoints documented
- ✅ `docs/ARCHITECTURE.md` - System design
- ✅ `docs/CHANGELOG.md` - Breaking changes log
- ✅ `CLAUDE.md` - Development guidelines + Docker setup
- ✅ `test-endpoints.sh` - Manual test script

## 🎯 Immediate Action Items

### Frontend Team - START TODAY

**Setup (5 minutes)**:
```bash
# 1. Start Docker services
docker-compose up -d

# 2. Start API
dotnet run --project Codex.Api/Codex.Api.csproj

# 3. Test connectivity
curl -X POST http://localhost:5246/api/query/health \
  -H "Content-Type: application/json" -d '{}'
# Expected: true
```

**Next Steps**:
1. ✅ Review `docs/COMPLETE-API-REFERENCE.md` for API contract
2. ✅ Generate TypeScript/Dart types from documentation
3. ✅ Create API client wrapper (see examples in docs)
4. ✅ Build first UI screens (no backend blockers)

### Backend Team - THIS WEEK

**Priority 1 (Critical)**:
1. ⚠️ Export OpenAPI spec: `./export-openapi.sh` → `docs/openapi.json`
2. ⚠️ Keep API running during frontend development
3. ⚠️ Monitor frontend integration feedback

**Priority 2 (Recommended)**:
1. Add integration tests (xUnit + TestContainers)
2. Setup CI/CD pipeline (GitHub Actions)
3. Create frontend SDK generation script

**Priority 3 (v2)**:
- JWT authentication
- Pagination for list endpoints
- Real-time updates (SignalR)

### DevOps Team - PLAN NOW

**Week 1**:
1. Design Azure infrastructure (App Service, PostgreSQL, Container Registry)
2. Draft Terraform scripts
3. Plan monitoring strategy (Application Insights)

**Week 2**:
1. Setup CI/CD pipeline (GitHub Actions)
2. Configure staging environment
3. Establish backup strategy

## 🚦 GO/NO-GO Decision

### **DECISION: GO ✅**

**Green Lights**:
- All core functionality operational
- Database stable and optimized
- Docker infrastructure healthy
- Complete documentation available
- No blocking issues identified

**Yellow Lights** (Non-blocking):
- Automated tests recommended (manual tests passing)
