Debugging and Troubleshooting Skills Pack for Claude Code

The Debugging and Troubleshooting Skills Pack gives Claude Code advanced diagnostic capabilities with four specialized skills and three slash commands. Stop guessing at bugs — this pack brings systematic debugging, log analysis, performance profiling, and adversarial verification directly into your workflow.

What You Get

• Systematic Debugging Skill — Follows a structured debugging methodology: reproduce, isolate, identify root cause, fix, and verify. Never chase symptoms again when Claude Code tracks down the actual source of every bug
• Log Analysis Skill — Parses application logs, identifies error patterns, correlates events across services, and pinpoints the exact sequence of events leading to failures
• Performance Profiling Skill — Identifies bottlenecks in CPU usage, memory allocation, database queries, and network requests with concrete optimization recommendations
• Adversarial Verification Skill — Actively tries to break your fix by testing edge cases, race conditions, and boundary values to ensure the bug is truly resolved
• /debug Command — Launches a structured debugging session for any error message or unexpected behavior
• /profile Command — Profiles a specific function or endpoint and returns a performance report with optimization suggestions
• /verify Command — Runs adversarial tests against your recent fix to confirm it holds under stress

How to Install

Extract into your .claude/ directory. Use /debug with an error description to start a guided debugging session. The /profile command works on any function or endpoint. After fixing a bug, run /verify to ensure your fix is bulletproof.

Who This Is For

• Developers spending too much time tracking down elusive bugs
• Backend engineers debugging performance issues in production systems
• Teams that want a repeatable, systematic approach to troubleshooting
• Anyone who has ever said “it works on my machine” and wants to fix that

Pair this with our other skills packs from the best Claude Code configs collection for maximum productivity.
