Accessibility & WCAG Compliance

Provides WCAG 2.1 Level AA compliance patterns for accessible web development including semantic HTML, ARIA implementation, keyboard navigation, and screen reader compatibility.

Description

This skill teaches accessibility agents how to evaluate and implement WCAG 2.1 Level AA standards across web applications. It covers the four POUR principles (Perceivable, Operable, Understandable, Robust), ARIA attributes, keyboard navigation patterns, color contrast requirements, and assistive technology compatibility.

When to Use

• Reviewing UI components for accessibility compliance
• Implementing keyboard navigation
• Adding ARIA labels and roles
• Evaluating color contrast ratios
• Testing screen reader compatibility
• Conducting WCAG 2.1 audits

When NOT to Use

• Do not use for backend-only changes with no user-facing output.
• Do not use for internal CLI tools where accessibility standards do not apply.
