What it does
Audit Library is an agent skill from selfishprimate/gerillass. Sweep every mixin and function in Gerillass and report where it misbehaves — silent failures, unhelpful errors, questionable output, and gaps in test coverage. Use when asked to audit or comprehensively test the library, before a release, or after a change that touches many mixins.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering CSS and styling and Test coverage. The repository describes itself as: Gerillass is a Sass mixin library containing a set of Sass mixins and functions to help front-end developers generate scalable CSS outputs.
When your agent uses it
- Comprehensively test the library
- Before a release
- After a change that touches many mixins
Example prompts
- “/audit-library”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- The suite
- The adversarial sweep
- Generated files
- What the tests do not assert
- The packed artifact
What it can do on your machine
Read from SKILL.md and the folder at commit 65f6638. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npmnodegit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Audit Library loads about 2k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 1,152 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,152 words (~2,030 tokens).
“npm test only checks inputs somebody already thought of. This audit throws arguments nobody wrote a test for at all 55 mixins and all 24 functions, at every argument position, and reports what the library does with them. Run it…”
