A coding-agent plugin for auditing automated test suites. It focuses on whether tests check important behavior rather than merely making the suite larger.

Reviewing a project's tests for useful coverage, brittle checks, duplicated assertions, and missing cases. It is intended to improve test quality without blindly adding tests.

It helps expose meaningful coverage gaps, fragile checks, and repeated assertions in existing tests. The available description does not specify particular programming languages or test frameworks.

Security

Grade A, and why

unit-tests 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.
