Stack Trace Analyzer

What this skill does

This skill directs the agent to read a stack trace, identify which frame is the true origin of the bug (not just where the error was thrown), explain what each relevant frame means in plain English, diagnose the root cause, and propose 2–3 concrete fixes ranked by likelihood. It works with JavaScript, TypeScript, Python, Java, Go, Rust, and most other common stack trace formats.

Use this when you have a crash report, a CI failure, or a wall of red text in your terminal and you want to understand it fast.

How to use

Claude Code / Cline

Copy this file to .agents/skills/stack-trace-analyzer/SKILL.md in your project root.

Then paste the stack trace and ask:

• "Analyze this stack trace using the Stack Trace Analyzer skill."
• "Use the Stack Trace Analyzer skill — what went wrong and how do I fix it?"

Include any relevant context: the action that triggered the error, environment details (Node version, browser, OS), and any recent code changes.
