Accessibility Audit Skill

This skill produces a structured accessibility audit based on WCAG 2.2 guidelines. It covers visual, motor, cognitive, and screen reader accessibility — with prioritised remediation for each issue found.

Required Inputs

Ask the user for these if not provided:

• What is being audited (screen, component, full product, design spec)
• Description or image of the UI
• Target WCAG level (A / AA / AAA — default to AA, which is the legal standard in most jurisdictions)
• Known assistive technology users? (Yes/No — if yes, which: screen reader / switch access / voice control / magnification)
• Platform (Web / iOS / Android / Desktop app)
