What is code-auditor?

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.

Use it for diff-scoped checks involving code quality, SOLID principles, linting, and project invariants.

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 yesterday.

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 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.
