LangSmith Fetch & Debug skill
Debugs LangChain and LangGraph agents by automatically fetching and analyzing execution traces from LangSmith Studio. The first AI observability skill — lets agents diagnose other agents.
Why it matters
As multi-agent systems grow complex, debugging agent behavior requires specialized tooling. This skill turns the problem of "why did the agent do that?" into a solvable question.
How to install LangSmith Fetch & Debug
- With the skills CLI. One command copies the skill into your project:
npx skills add ComposioHQ/awesome-claude-skills - In AGNT. Download AGNT free, then add the skill folder from Skills → Import. It runs with the model you choose, next to your agents, workflows and memory.
