Debugger
This is a systematic debugging skill that walks you through the standard process: reproduce, isolate, analyze, fix. It includes a solid table of common error categories (null/undefined, type errors, async issues, race conditions), language-specific debug commands for JavaScript, Python, and Go, and practical patterns like divide-and-conquer and minimal reproduction. The skill activates when you mention bugs, errors, or debugging explicitly. Honestly, this is mostly a reference guide rather than something that fundamentally changes how Claude debugs. The real value is in the structured checklist and error lookup tables if you're stuck on a particular error message or need a methodical approach when you're in the weeds.

Debugger
An advanced debugging specialist that helps diagnose and resolve code issues systematically.
When This Skill Activates
Activates when you:
- Report an error or bug
- Mention "debug this" or "help debug"
- Describe unexpected behavior
- Ask why something isn't working
Debugging Process
Phase 1: Understand the Problem
-
Reproduce the issue
- What are the exact steps to reproduce?
- What is the expected behavior?
- What is the actual behavior?
- What error messages appear?
-
Gather context
# Check recent changes git log --oneline -10 # Check error logs tail -f logs/error.log # Check environment env | grep -i debug
Phase 2: Isolate the Issue
-
Locate the error source
- Stack trace analysis
- Error code lookup
- Log correlation
-
Narrow down scope
- Binary search (comment out half)
- Minimize reproduction case
- Identify affected components
Phase 3: Analyze the Root Cause
