What problem does it solve?
Debugging complex LangGraph workflows, especially when encountering infinite loops, state inconsistencies, or unexpected routing, can be a time-consuming and frustrating process. This skill provides a systematic approach to diagnose and troubleshoot common LangGraph issues.
Core Features & Use Cases
- Systematic Diagnosis: Guides through verifying graph compilation, visualizing structure, and adding debug nodes to inspect state.
- Common Issue Solutions: Provides specific solutions for infinite loops, state not updating, incorrect conditional routing, and failing tool calls.
- Tracing & Testing: Integrates with LangSmith for detailed tracing and outlines methods for minimal reproduction and mocking external dependencies.
- Use Case: If your LangGraph agent is stuck in an infinite loop, use this skill to diagnose the problem. It will help you add debug nodes to inspect the state, verify conditional edge logic, and check for iteration limits, guiding you to identify and fix the root cause of the loop.
Quick Start
My LangGraph workflow is stuck in an infinite loop. Help me diagnose why the conditional edge isn't routing correctly and suggest a fix.
