crap-analysis

crap-analysis is a skill for Claude Code, Codex from F-U-S-E-E/FuseDevelopmentGroup. It costs 45 tokens per session (2,773 once invoked), scanned C, original, AGPL-3.0.

A code-risk analysis based on test coverage and CRAP scores, which combine code complexity with how much of the code tests exercise.

In plain words
What is it for?
Use it with OpenCover coverage reports and ReportGenerator to find risk hotspots, complex code, and untested paths.
Why use it?
It highlights code that is complicated and poorly tested, where changes are more likely to cause problems.

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 C, and why

crap-analysis scanned grade C 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 3d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.
