proctor

proctor is a plugin for Gemini CLI from catfish-1234/proctor. Its token cost is not measured, scanned A, original, MIT.

A test-protection add-on that checks whether an AI coding agent has cheated to make a test suite pass. It looks for deleted or skipped tests, weakened checks, and hardcoded outputs.

In plain words
What is it for?
Use it when reviewing agent-made code and its test changes.
Why use it?
It helps distinguish a genuinely working change from a green test result created by changing the tests or faking their answers.

Security

Grade A, and why

proctor 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 2d ago.

The scan reads gemini-extension.json. This mod also ships 8 executable files (scripts/build-detection-core.mjs, scripts/detection-cases.mjs, scripts/evaluate-detection.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.
