qa-check

A project-audit skill that detects whether code uses WordPress, PHP, Python, Node.js, or static web files, then checks accessibility, speed, and code quality.

In plain words
What is it for?
Use it to audit a whole project or selected files for WCAG 2.2 AA accessibility issues, performance problems, and code-quality concerns.
Why use it?
It provides a structured report of problems without changing the project, so developers can review issues before fixing them.

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

qa-check scanned grade A with 1 finding 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.

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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

- No `eval()`, `Function()`, or `child_process.exec()` with user input.

Skill: qa-check (Global)

When to Use

Run /qa-check on any web project to audit for Accessibility (WCAG 2.2 AA), Performance, and Code Quality issues. This skill auto-detects the tech stack and adapts its checks accordingly.

Use $ARGUMENTS to scope the audit to a specific directory or file pattern (e.g., /qa-check src/components/). If empty, audit the entire project.

Do NOT fix issues - only report them. Present findings as structured Markdown tables.

Method

Phase 0: Stack Detection

Before running any checks, detect the project's tech stack by scanning the working directory for marker files. Report what was detected before proceeding.

Detection Rules

Scan in this order. A project can match multiple stacks (e.g., WordPress with Node build tools).

Stack Marker Files
WordPress / PHP wp-config.php, composer.json with "wordpress", style.css containing Theme Name:, functions.php, wp-content/ or content/ directory
Python requirements.txt, pyproject.toml, setup.py, setup.cfg, Pipfile, manage.py (Django), app.py or wsgi.py (Flask)
Node / JS package.json - then inspect for framework indicators: next (Next.js), express (Express), nuxt (Nuxt), @angular/core (Angular), react (React), vue (Vue), svelte (Svelte)
Static Web *.html files in root or src/, *.css files, no backend markers detected
Detection Output

Print a summary before running checks:

## Stack Detection

| Stack | Detected | Markers Found |
|---|---|---|
| WordPress/PHP | Yes/No | wp-config.php, style.css (Theme Name: ...) |
| Python | Yes/No | requirements.txt, manage.py |
| Node/JS | Yes/No | package.json (express, react) |
| Static Web | Yes/No | index.html, styles.css |

Then determine which template/view files to scan:

  • WordPress: *.php in theme directory, template-parts/, templates/, inc/
  • Python (Flask): templates/**/*.html, app/templates/**/*.html
  • Python (Django): **/templates/**/*.html, **/templatetags/*.py
  • Node (Next.js): pages/**/*.{js,jsx,tsx}, app/**/*.{js,jsx,tsx}, components/**/*.{js,jsx,tsx}
  • Node (Express): views/**/*.{ejs,pug,hbs,html}, public/**/*.html
  • Node (React/Vue/Svelte): src/**/*.{jsx,tsx,vue,svelte}
  • Static Web: *.html, src/**/*.html

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.

qa-check is a skill published in the GitHub repository stuartshields/claude-setup (2 stars, last pushed 3mo ago), licensed MIT. It adds 41 tokens to every session and 3,816 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
