Tracing helps you see what your AI application does step by step. You can find errors and understand how it works. This skill covers two main topics: adding tracing to your app and querying traces for debugging.
For LangChain and LangGraph apps, tracing is automatic. Just set a few environment variables. For other apps, use the traceable decorator or wrap your LLM client. Both Python and JavaScript are supported.
You can also search through past traces to find problems. Use the LangSmith CLI tool to list and export trace data. It is a simple way to keep your AI apps working well.
