create-audit

A skill for adding a new audit module to check-ai, a scanner that checks whether a repository contains files, folders, or patterns that support AI-assisted development. Each audit is a separate JavaScript module.

In plain words
What is it for?
Use it when you need check-ai to inspect a new file, directory, or pattern. It creates an audit with checks, labels, weights, paths, and optional custom analysis.
Why use it?
It lets you add a new kind of repository check without changing the scanner, scoring system, or report generator. The module is discovered automatically when the scanner runs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-audit 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.

The scan reads SKILL.md. This mod also ships 1 executable file (references/mcp-audit-example.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.

How it starts

The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Audit

Create new audit modules for the check-ai AI-readiness scanner. Each audit is a single .mjs file in src/audits/ that is dynamically loaded at scan time — no changes to scanner, scorer, or reporter needed.

Audit File Contract

Every audit file must export:

export const section = 'Section Name';  // shown in report
export const checks = [ ... ];          // array of check objects
// optional:
export function analyze(rootDir, ctx) { return { 'custom-key': { found, detail } }; }

The scanner auto-discovers all .mjs files in src/audits/, sorted alphabetically.

Check Object Schema

{
  id: 'unique-kebab-id',        // unique across all audits
  label: 'Display label',       // shown in terminal output
  section,                       // use the exported section constant
  weight: 5,                    // 1-20, impact on score
  paths: ['file.md', '.dir/'],  // candidate paths to probe
  type: 'file',                 // see Check Types below
  description: 'Why this matters for AI-readiness',
}

Check Types

Type Behavior
file Exists as a file at any of paths
dir Exists as a directory at any of paths
any Exists as either file or directory
deep-scan Walks the file tree for deepPattern matches (requires deepPattern field)
custom Handled by the audit's analyze() function (requires custom field matching a key in analyze's return)

Weight Guidelines

Weight Meaning
1-2 Nice to have
3-4 Useful signal
5-7 Important
8-10 High impact
15-20 Critical (use sparingly)

What ships with it

1 file beside SKILL.md 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.

create-audit is a skill published in the GitHub repository f/check-ai (67 stars, last pushed 5mo ago), licensed MIT. It adds 66 tokens to every session and 1,182 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
