What it does
Accessibility problems on a page or in your code come back as a ranked list, checked against WCAG 2.2. Ask for fixes and it repairs them and checks again. The skill first works out whether you want a report only or a fix. In report mode it changes nothing. It tries a live audit of a web address first, using a connected browser. Otherwise it reads the code. Each finding is ranked by impact. In fix mode it edits, then re-runs the check to confirm the problem is gone. Automated checks cover only part of WCAG, so the skill says so rather than claiming full conformance. It needs a checking tool or browser connection.
You give it
- A page address or the code folder
- Report only or fix as well
- A signed-in browser session, if the page needs one (optional)
- The pages or parts to focus on (optional)
- Your website (optional)
- Codebase (optional)
You get
- A ranked list of WCAG 2.2 problems
- The place in the page or code for each
- Fixes applied and re-checked, if you asked
- A note on what automated checks cannot cover
Use it when
- You are about to launch a page and want to find barriers first.
- A customer says your site is hard to use with a screen reader.
- You want colour contrast problems fixed and confirmed.
- You need a report to hand to your developers.
How to use it
- Add it to your AI once: download it and add the folder to Claude, ChatGPT or Codex as a skill.
- Ask for the job in your own words. Your AI opens the skill when it fits.
- It works best when your AI can run code and open a browser.
