debug

debug is a skill for Claude Code from nota-america/forgecat-agent-profiles. It costs 53 tokens per session (725 once invoked), scanned A, a copy of debug, Apache-2.0.

A structured process for finding the cause of a software problem by reproducing it, narrowing its location, and checking relevant evidence.

In plain words
What is it for?
Use it for error messages, stack traces, production-only failures, or behavior that changed after a deployment.
Why use it?
It replaces guesswork with a repeatable way to compare expected and actual behavior and identify the faulty code or configuration.

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 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.
