Systematic Debugging

Systematic Debugging is a skill for Claude Code, Codex from Raidriar7170/hermes-skilleval. It costs 25 tokens per session (298 once invoked), scanned A, original, MIT.

A step-by-step method for finding the cause of a software failure before changing code.

In plain words
What is it for?
Use it to reproduce bugs, investigate flaky tests and runtime errors, isolate the failing path, and verify a fix.
Why use it?
It prevents guesswork and quick fixes that hide the real problem or introduce new ones.

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

Systematic Debugging 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

Systematic Debugging

Use when a failure, flaky test, runtime error, or unexpected behavior needs investigation before implementation. Reproduce the symptom, gather observations, form one hypothesis at a time, and verify the root cause before changing code.

Evidence

  • Reproduction command and observed failure.
  • Narrowed cause with file or interface evidence.
  • Fix validation and remaining risk.

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.
