bug-fix

bug-fix is a skill for Claude Code from mark22013333/crew. It costs 85 tokens per session (5,699 once invoked), scanned A, original, no licence file.

A bug-fixing workflow that requires finding the underlying cause before changing code. It also produces fix suggestions, repeat-check tests, and browser checks.

In plain words
What is it for?
Use it to investigate a bug, identify its root cause, suggest a fix, add regression tests, and verify the result in a browser.
Why use it?
It reduces the risk of patching symptoms and causing the same bug to return. It gives each fix a clear way to check whether it worked.

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

bug-fix scanned grade A with 1 finding 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 19d 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.

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.
