Does this skill require external software?

Yes, you must have the langsmith-fetch CLI installed via pip and have your LANGSMITH_API_KEY and LANGSMITH_PROJECT environment variables configured.

What output formats are supported?

The skill supports 'pretty' format for human-readable terminal output, 'json' for detailed data analysis, and 'raw' for piping into other command-line tools.

What is the LangSmith Fetch Claude Skill?

It is a specialized capability for Claude Code that allows you to interact with LangSmith Studio to retrieve, analyze, and debug execution traces for AI agents.

How do I identify why my agent is slow?

You can use the 'Performance Issues' workflow to export traces with metadata, allowing the skill to analyze tool call latencies and identify bottlenecks.

Can I use this for LangGraph agents?

Absolutely. This skill is designed to work with both standard LangChain implementations and complex LangGraph state machines.

分析与监控

Debugs LangChain and LangGraph agents by fetching and analyzing execution traces directly from LangSmith Studio.

关于

LangSmith Fetch is a specialized debugging skill designed to streamline the analysis of LangChain and LangGraph agents. It allows developers to retrieve recent execution traces, investigate tool calls, check memory operations, and analyze performance metrics without leaving the terminal. By integrating directly with LangSmith Studio via the CLI, it provides actionable insights into agent failures, token usage, and complex execution flows, making it an essential tool for developers building and optimizing production-grade AI agent workflows.
