Claude SDK & Runtime Patterns

When to apply

Apply whenever touching Claude SDK invocations, MCP server imports, subprocess vs API mode selection, or streaming message handling.

Rules

The TAO engine in src/tao/ is stub scaffolding — it is NOT used by the web server. All intelligence is delegated to Claude via the SDK (API key mode). Check the ANALYSIS_MODE env var: Railway deployments must use API mode, not CLI mode.
claude -p subprocess mode requires the Claude Code CLI installed in PATH. In cloud environments (Railway), Claude Code is NOT available — cloud deployments must use ANTHROPIC_API_KEY + SDK mode exclusively.
MCP SDK subpath imports are required: '@modelcontextprotocol/sdk/server/mcp.js' and '../server/stdio.js'. The top-level '@modelcontextprotocol/sdk' import does NOT export McpServer directly — importing from it will fail silently or throw at runtime.
When using claude_agent_sdk.ClaudeSDKClient, use the public async for message in client.receive_response() loop — NOT the private _query.receive_messages(). Private API methods break on SDK upgrades.
The AbortController signal must be passed to client.messages.stream() as the second options argument: client.messages.stream({...}, { signal }) — not inside the first object. Placing it inside the first argument silently ignores the abort signal.
