Find out why your LangChain agent failed.
Retrieves agent execution traces and analyzes failures, tool calls, memory operations, and performance to help diagnose problems.
When to use it
Use when asked to debug an agent, inspect recent traces or errors, analyze memory, review performance, or explain tool calls.
Give it an agent-debugging question; it fetches execution traces and returns an analysis of errors, tool calls, execution times, and token usage.
Requires the langsmith-fetch CLI to be installed.
Requires access to a LangSmith project through an API key and a configured project name.
