Debugging and Troubleshooting Skills Pack for Claude Code

The Debugging and Troubleshooting Skills Pack for Claude Code adds four targeted diagnostic skills and three slash commands that let you move from symptom hunting to systematic resolution. By embedding a reproducible debugging workflow, log‑driven failure analysis, performance bottleneck detection, and adversarial verification directly into Claude Code, you spend less time guessing and more time confirming fixes.

What You Get

• Systematic Debugging Skill – Executes a repeatable process: reproduce the issue, isolate the component, identify the root cause, apply a fix, and verify the result. Claude Code records each step so you avoid chasing downstream symptoms.
• Log Analysis Skill – Reads application logs, extracts error patterns, correlates events across services, and builds a timeline that points to the exact sequence leading to a failure.
• Performance Profiling Skill – Scans CPU usage, memory allocation, database queries, and network calls, then reports the most expensive operations with concrete suggestions for optimization.
• Adversarial Verification Skill – Generates edge‑case inputs, race‑condition scenarios, and boundary tests that attempt to break a recent fix, confirming that the bug is truly resolved.
• /debug Command – Starts a structured debugging session for any error message or unexpected behavior, guiding Claude Code through the systematic debugging steps.
• /profile Command – Profiles a specified function or endpoint and returns a performance report that includes hot spots and actionable recommendations.
• /verify Command – Executes adversarial tests against the latest changes to ensure stability under stress and unusual conditions.

How to Use

Invoke a command from Claude Code’s prompt bar, for example /debug followed by the error text. Claude Code will ask clarifying questions, reproduce the issue in a sandbox, and walk you through isolation. Use /profile on a function name to receive a detailed timing breakdown. After applying a fix, run /verify to automatically generate edge‑case tests; the tool reports any failures and suggests additional checks before you consider the issue closed.

Who This Is For

This pack is aimed at developers who regularly work with Claude Code and need reliable, repeatable debugging assistance. It suits engineers maintaining microservice architectures, those optimizing resource‑intensive code paths, and anyone who wants a built‑in safety net against regressions after a fix.
