debugging-strategies

debugging-strategies is a skill for Claude Code, Codex from mattmre/EVOKORE-MCP-PUBLIC. It costs 43 tokens per session (3,028 once invoked), scanned A, a copy of debugging-strategies, MIT.

A methodical guide to finding the cause of bugs, crashes, memory leaks, and slow or unexpected behavior. It uses reproduction, isolation, hypotheses, experiments, profiling, and root-cause analysis.

In plain words
What is it for?
Use it to investigate application bugs, analyze stack traces and crash dumps, profile performance, find memory leaks, and diagnose production or distributed-system problems.
Why use it?
It replaces guesswork with a repeatable way to investigate problems. This makes difficult issues easier to narrow down, including failures in production and distributed systems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

debugging-strategies scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Debugging Strategies

Transform debugging from frustrating guesswork into systematic problem-solving with proven strategies, powerful tools, and methodical approaches.

When to Use This Skill

  • Tracking down elusive bugs
  • Investigating performance issues
  • Understanding unfamiliar codebases
  • Debugging production issues
  • Analyzing crash dumps and stack traces
  • Profiling application performance
  • Investigating memory leaks
  • Debugging distributed systems

Core Principles

1. The Scientific Method

1. Observe: What's the actual behavior? 2. Hypothesize: What could be causing it? 3. Experiment: Test your hypothesis 4. Analyze: Did it prove/disprove your theory? 5. Repeat: Until you find the root cause

2. Debugging Mindset

Don't Assume:

  • "It can't be X" - Yes it can
  • "I didn't change Y" - Check anyway
  • "It works on my machine" - Find out why

Do:

  • Reproduce consistently
  • Isolate the problem
  • Keep detailed notes
  • Question everything
  • Take breaks when stuck

3. Rubber Duck Debugging

Explain your code and problem out loud (to a rubber duck, colleague, or yourself). Often reveals the issue.

Systematic Debugging Process

Phase 1: Reproduce

## Reproduction Checklist

1. **Can you reproduce it?**
   - Always? Sometimes? Randomly?
   - Specific conditions needed?
   - Can others reproduce it?

2. **Create minimal reproduction**
   - Simplify to smallest example
   - Remove unrelated code
   - Isolate the problem

3. **Document steps**
   - Write down exact steps
   - Note environment details
   - Capture error messages

Phase 2: Gather Information

## Information Collection

1. **Error Messages**
   - Full stack trace
   - Error codes
   - Console/log output

2. **Environment**
   - OS version
   - Language/runtime version
   - Dependencies versions
   - Environment variables

3. **Recent Changes**
   - Git history
   - Deployment timeline
   - Configuration changes

4. **Scope**
   - Affects all users or specific ones?
   - All browsers or specific ones?
   - Production only or also dev?
