debugging-methodology

debugging-methodology is a skill for Claude Code, Codex from magnus919/hermes-profiles. It costs 24 tokens per session (215 once invoked), scanned A, original, MIT.

A step-by-step method for finding and fixing software bugs. It covers reproducing the failure, narrowing down where it occurs, finding its underlying cause, applying a fix, and checking the result.

In plain words
What is it for?
Use it to investigate crashes, incorrect results, and slow or memory-heavy software. It helps organize reproduction checks, cause analysis, isolation, and verification.
Why use it?
It replaces guesswork with a repeatable investigation process, especially when a failure is intermittent or involves several parts of a system.

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-methodology 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 5d 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.

What it actually says

Debugging Methodology

Systematic process for investigating and resolving software defects.

The Debugging Lifecycle

REPRODUCE → ISOLATE → ROOT CAUSE → FIX → VERIFY

Reference Files

Reference When to load
references/reproduction-checklist.md You need to reproduce an intermittent or environment-specific failure
references/root-cause-analysis.md You've isolated the symptom and need to trace to root cause
references/isolation-techniques.md You need to narrow down a failure across multiple components
references/performance-debugging.md Investigating latency, memory, or throughput issues
Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
