debug

debug is a skill for Claude Code from renanflustosa/octo-cluster. It costs 18 tokens per session (159 once invoked), scanned A, original, MIT.

A debugging workflow that starts with runtime evidence such as a failing test, log, or search result. It reproduces the failure, makes the smallest fix, and reruns a focused check.

In plain words
What is it for?
Use it for flaky tests, hung processes, permission errors, HTTP 500 responses, or missing dependencies that appear during a run.
Why use it?
It reduces guesswork and discourages unrelated refactoring while fixing a failure. The result includes the cause, the fix, and a command that proves the result.

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

debug 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 1mo 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

debug

Debug mode. Fix bugs with runtime evidence, not speculation.

Problem: $ARGUMENTS

Gather a reproducible signal (test, logs, grep) before each hypothesis. Then: reproduce -> minimal fix -> scoped re-run. No refactors.

When: flaky test, hung process, permission error, API 500, missing dependency mid-run. When NOT: design questions, refactors, or fixes without a reproducible failure.

Output: root cause (1 line) + fix + proof command, <=30 lines. Skill: systematic-debugging.

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.
