debug

debug is a skill for Claude Code from charlieviettq/awesome-agent-skill. It costs 53 tokens per session (713 once invoked), scanned A, a copy of debug, MIT.

A guided debugging method that helps you reproduce a software problem, narrow down where it occurs, find its cause, and fix it.

In plain words
What is it for?
Use it to work through error messages, stack traces, broken deployments, staging-versus-production differences, and unexpected behavior.
Why use it?
It replaces guesswork with a repeatable investigation, especially when an error is unfamiliar or software behaves differently across environments.

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is If you see unfamiliar placeholders or need to check which tools are connected, see [CONNECTORS.md](../CONNECTORS-engineering.md)..

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 9d 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.

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.
