What changed
CrewAI integration (
integrations/crewai.py)Zero-code instrumentation for CrewAI. Install and enable:
Or via env var:
AGENT_STRACE_AUTO_INSTRUMENT=crewai python my_crew.pyPatches:
Crew.kickoff→session_start/session_endwith crew/task countsAgent.execute_task→llm_request/llm_responsewith agent role and task descriptionTask.execute_sync→tool_call/tool_resultwith durationLangGraph node-level tracing (
integrations/langchain.py)When
langgraphis installed,instrument_langchain()now also patchesStateGraph.compileto wrap each compiled node withdecision+tool_resultevents, giving per-node latency and error visibility. Falls back silently if LangGraph is not installed.uninstrument_langchain()now properly restores all three patches (tool run, generate, compile).Registry
