Debug LangChain and LangGraph agents by fetching execution traces

langsmith-fetch is an agent skill from Composio's Awesome Claude Skills collection on GitHub. It debugs LangChain and LangGraph agents by fetching their execution traces from LangSmith Studio into your terminal and analyzing errors, tool calls, memory operations and performance. A skill is a SKILL.md file of instructions (sometimes with scripts and reference notes) that an AI agent loads only when a task calls for it, so the agent knows the steps to follow and what to avoid. It is free and open source.
