SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the debugging of LangChain and LangGraph agents by directly fetching and analyzing execution traces from LangSmith Studio, simplifying error identification and performance monitoring.

Core Features & Use Cases

  • Fetch Recent Traces: Automatically retrieve recent agent activity for quick debugging.
  • Deep Dive Analysis: Investigate specific trace IDs for in-depth error root cause analysis.
  • Export Sessions: Save traces and threads for offline review and team collaboration.
  • Error Detection: Quickly identify and report on common failure patterns.
  • Use Case: When an agent behaves unexpectedly, use this Skill to instantly pull the last 5 minutes of execution traces, identify any tool failures, and get a summary of what went wrong.

Quick Start

Use the langsmith-fetch skill to debug your agent by fetching the last 5 minutes of traces.

Frequently Asked Questions about langsmith-fetch

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug LangChain agent execution traces to find tool failures?▼

Debug LangChain agent execution traces by fetching recent activity directly from LangSmith Studio, which retrieves performance metrics and identifies tool failures. This allows you to analyze agent behavior and pinpoint error root causes quickly.

What is the best way to analyze LangGraph agent memory operations during execution?▼

Analyzing LangGraph agent memory operations is best done by fetching specific trace IDs from LangSmith Studio for deep dive analysis. This process exposes memory operations and execution paths, facilitating root cause analysis for unexpected agent behavior.

Can I export LangSmith traces for offline review and team collaboration?▼

Yes, you can export LangSmith traces and threads to save sessions for offline review. This feature enables team collaboration by allowing you to share execution records outside the LangSmith Studio environment.

Why does my LangChain agent behave unexpectedly and how can I identify what went wrong?▼

When a LangChain agent behaves unexpectedly, you can identify what went wrong by pulling the last 5 minutes of execution traces. This fetches agent activity, highlights tool failures, and generates a summary of the error.
