Can I use this with LangSmith?

Yes, the skill includes specific steps to enable LangSmith tracing (v2) alongside local logging to provide maximum visibility into your chains.

Do I need to install any extra packages?

The skill assumes you have LangChain installed, but it provides the necessary code to audit and verify your existing installation environment.

How do I trigger the LangChain debug collection?

You can trigger the skill by asking Claude phrases like 'langchain debug bundle', 'langchain diagnostics', or 'collect langchain logs'.

Does this skill handle sensitive information?

The skill includes clear instructions and checklists for redacting API keys and sensitive environment variables before you submit your debug bundle.

About

The LangChain Debug Bundle is a specialized Claude Code skill designed to help developers capture comprehensive technical evidence when encountering issues in LangChain workflows. It automates the collection of environment specifications, package versions, and granular LLM/tool execution traces while facilitating the creation of minimal reproduction scripts. By standardizing the diagnostic output into a structured JSON bundle, it enables faster resolution of complex chain failures and provides production-ready evidence for GitHub issues, team collaboration, or LangChain support tickets.
