✅ What's Ready NOW

Infrastructure

• ✅ PostgreSQL 15: Running via Docker (localhost:5432)
• ✅ Ollama: AI model server ready (localhost:11434, phi model loaded)
• ✅ Database Schema: 6 tables with proper indexes and foreign keys
• ✅ Migrations: Applied and verified via EF Core
• ✅ CORS: Configured for localhost development (ports 3000, 54952, 62000)

API Endpoints (16 Total)

Commands (6):

1. POST /api/command/createAgent - Create AI agents
2. POST /api/command/updateAgent - Update agent config
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

🎯 Immediate Action Items

Frontend Team - START TODAY

Setup (5 minutes):

# 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
