claude-crap

claude-crap is a plugin for Claude Code from ahernandez-developer/claude-crap. Its manifest loads nothing; the 4 skills, 5 hooks, 1 MCP server it bundles cost 742 tokens per session together, scanned A, original, MIT.

A Claude Code plugin that checks code quality around file edits and shell commands, using code metrics and security-analysis reports.

In plain words
What is it for?
Running checks before Write, Edit, and Bash actions, verifying changes afterward, applying a stop-time quality gate, measuring technical debt and syntax-tree metrics, and generating SARIF 2.1.0 reports.
Why use it?
It is intended to stop functional code from being written before a test safety net exists and to apply quality gates during development.

Security

Grade A, and why

claude-crap 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 installs

The manifest is a name and a version. 4 skills, 5 hooks, 1 MCP server travel with it, and installing the plugin installs all of them — 742 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
