estatewise-ai-runtime

name: estatewise-ai-runtime description: Playbook for MCP, agentic-ai, web-grounding, token flows, and A2A in EstateWise. Use when changing tool calls, orchestration, runtime behavior, or AI integration paths. argument-hint: [mcp-agentic-a2a-scope]

EstateWise AI Runtime

Use this skill when work touches the tool-first AI stack rather than just the app UI/API.

System Boundaries

• backend/: source APIs behind property, graph, analytics, auth, finance, and chat behavior.
• mcp/: stdio server that exposes those capabilities as tools.
• agentic-ai/: consumers and orchestrators that call MCP tools, plus optional HTTP/A2A access.

Core Files

• MCP entry: mcp/src/server.ts
• MCP config: mcp/src/core/config.ts
• MCP tool registry: mcp/src/tools/index.ts
• MCP A2A bridge: mcp/src/tools/a2a.ts
• MCP system/monitoring tools: mcp/src/tools/system.ts, mcp/src/tools/monitoring.ts
• Agentic CLI: agentic-ai/src/index.ts
• Agentic HTTP/A2A server: agentic-ai/src/http/server.ts
• Agentic default orchestrator: agentic-ai/src/orchestrator/AgentOrchestrator.ts
• Agentic LangGraph wrappers: agentic-ai/src/lang/tools.ts, agentic-ai/src/lang/graph.ts
• Agentic A2A protocol: agentic-ai/src/a2a/

Runtime Modes

MCP only

Use when adding or fixing tool behavior:

cd mcp
npm run build
npm run client:dev
npm run client:call -- <tool> '<json>'

Remember: npm run dev waits for a stdio client and looks idle by design.

Agentic default orchestrator

Use when changing orchestration logic or end-to-end tool use:

cd mcp && npm run build
cd ../agentic-ai && npm run build
npm run dev "Find 3-bed homes in Chapel Hill and compare two ZPIDs"

LangGraph

Use when touching agentic-ai/src/lang/:

cd agentic-ai
npm run build
npm run dev -- --langgraph "Compare two Chapel Hill homes and estimate mortgage"

CrewAI

Use only when explicitly working in the Python runtime:

• Requires agentic-ai/crewai/requirements.txt
• Requires OPENAI_API_KEY
• Validate with npm run dev -- --crewai "goal"

HTTP / A2A

Key endpoints in agentic-ai/src/http/server.ts:

• GET /health
• POST /run
• GET /run/stream
• GET /.well-known/agent-card.json
• GET /a2a/agent-card
• POST /a2a

If these move, inspect mcp/src/tools/a2a.ts immediately.

Environment And Service Dependencies

• MCP:

  • API_BASE_URL
  • FRONTEND_BASE_URL
  • A2A_BASE_URL
  • WEB_TIMEOUT_MS
  • token env vars for mcp.token.*

• Backend-driven AI paths:

  • GOOGLE_AI_API_KEY
  • PINECONE_API_KEY
  • PINECONE_INDEX
  • Neo4j env vars for graph features

• Agentic runtime:

  • AGENT_RUNTIME
  • THREAD_ID
  • OPENAI_API_KEY for CrewAI and OpenAI-linked paths
  • A2A_MAX_TASKS, A2A_TASK_RETENTION_MS, A2A_WAIT_TIMEOUT_MS

Important Behavioral Rules

• MCP tool outputs should stay text-first and JSON-stringified where the repo already expects that pattern.
• Tool descriptions and input schemas are part of the user-facing contract.
• A2A task lifecycle semantics must stay coherent across agentic-ai and MCP bridge tools.
• LangGraph and orchestrator integrations should not silently diverge on tool naming or expected payload shape.
• Web-grounding changes should preserve timeout and failure-handling behavior.

Common Failure Patterns

• MCP build passes, but client:call fails because a tool name or schema changed.
• Agentic runtime compiles, but an MCP wrapper in agentic-ai/src/lang/tools.ts still expects the old payload shape.
• A2A server works directly, but mcp/src/tools/a2a.ts still targets an older endpoint or response structure.
• Cost reporting or THREAD_ID behavior changes in LangGraph without docs/examples being updated.
• Token flows appear to work locally but fail across process restarts because storage is in-memory.

Documentation Obligations

Update these when relevant:

• mcp/README.md
• agentic-ai/README.md
• root README.md
• ARCHITECTURE.md
• RAG_SYSTEM.md when AI-system behavior materially changes
