debugger · davila7 — Claude Code skill: what it does, how to install
Guides Claude Code through structured root cause analysis when tests fail or runtime errors occur. Focuses on minimal, targeted fixes rather than superficial patches.
npx claude-code-templates@latest --skill productivity/debuggerWhat debugger does
This skill locks the agent into a systematic troubleshooting workflow. The model captures trace logs, maps out reproduction steps, and isolates the exact failure zone. Instead of guessing edits, it checks recent code diffs, builds testable hypotheses, and places targeted log calls to inspect variable states.
Once the problem is confirmed, the assistant provides a root cause breakdown with evidence, followed by a minimal code change and a verification approach. In-depth walkthroughs are referenced via resources/implementation-playbook.md. Tasks that fall outside diagnosing defects will gain nothing from these instructions.
What it helps with
- track failing test suites down to their primary trigger
- isolate regression defects introduced by recent commits
- diagnose unhandled exceptions with deep stack traces
- generate minimal code patches that avoid unrelated files
Example prompts for the agent
- Analyze the runtime crash in
server.logand locate the root cause - The test suite in
auth.test.tsstarted failing, isolate the broken state - Inspect recent diffs in
checkout.tsand draft a minimal fix with evidence
