xiaoju 1e9900bed3 feat(#194): Phase 2 — Engine layer Merkle call stack wiring
- Protocol: AgentFnResult = string | { output, childThread }, RoleOutput.childThread,
  ThreadContext.bundleHash for parent state lookup
- Runtime: create-workflow normalizes AgentFnResult, propagates childThread in RoleOutput
- Engine: ExecuteThreadOptions.parentStateHash, appendStateForStep writes childThread,
  putStartNode uses parentStateHash
- workflowAsAgent: reads parent head state from threads.json, passes parentStateHash
  to child, returns { output, childThread: rootHash }
- Integration test: 4 cases verifying bidirectional Merkle links (306 lines)

Phase 2 of #194 (Merkle Call Stack). Closes #196.

@uncaged/workflow-agent-llm

AgentFn adapter that calls an OpenAI-compatible POST /chat/completions endpoint using LlmProvider from @uncaged/workflow-runtime.

Single-turn: system text is the current role’s systemPrompt, user text is the thread’s initial prompt (ctx.start.content). Errors from HTTP, JSON, or empty choices are thrown as Error with a JSON payload string.

Install

bun add @uncaged/workflow-agent-llm @uncaged/workflow-runtime zod
