code-auditor

code-auditor is a plugin for Claude Code from BenAHammond/code-auditor-mcp. Its manifest loads nothing; the 1 skill, 2 hooks it bundles cost 25 tokens per session together, scanned A, original, MIT.

A plugin that audits code changes as they are made. It indexes the codebase, checks edited areas against defined rules, and reports violations back to the coding agent.

In plain words
What is it for?
Use it for diff-scoped checks involving code quality, SOLID principles, linting, and project invariants.
Why use it?
It catches code-quality problems during editing, when they are still close to the change that caused them. This reduces the need to find all issues in a later review.

Security

Grade A, and why

code-auditor 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 4d 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.

Contents

What it installs

The manifest is a name and a version. 1 skill, 2 hooks travel with it, and installing the plugin installs all of them — 25 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
