falsegreen-skill

falsegreen-skill is a plugin for Gemini CLI from vinicq/falsegreen-skill. Its token cost is not measured, scanned A, original, MIT.

A test checker that looks for tests which pass even when the code they are meant to protect is broken. It uses a named J1–J6 review framework and supports Python, TypeScript, JavaScript, and Robot Framework.

In plain words
What is it for?
Use it to inspect automated tests and find cases that do not reliably fail when the related implementation is wrong.
Why use it?
A passing test can give false confidence if it never exercises the important behavior or would also pass after a bug is introduced. This helps identify that kind of misleading result.

Security

Grade A, and why

falsegreen-skill 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.

The scan reads gemini-extension.json. This mod also ships 36 executable files (examples/authoring/apply-discount.test.js, examples/authoring/apply-discount.test.ts, examples/authoring/test_apply_discount.py, …), 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 ships with it

42 files beside gemini-extension.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.
