Skill: accessibility

What I do

I ensure terminal applications are accessible to everyone, including users with disabilities. This skill covers WCAG principles, keyboard navigation, screen reader support, and testing strategies for inclusive TUIs.

When to use me

• Building terminal applications used by diverse audiences
• Implementing keyboard shortcuts and navigation
• Testing with screen readers
• Designing for users with disabilities
• Ensuring colour contrast compliance

Core principles

1. Keyboard navigation first—every feature accessible without mouse
2. Screen reader compatible—semantic structure, ARIA labels where applicable
3. High contrast—minimum 4.5:1 ratio for readability
4. Focus visible—clear indicator of current position
5. Test with real users—accessibility requires actual validation

Patterns & examples

Keyboard Navigation

Map all features to keyboard shortcuts. Test with Tab/Shift+Tab. Ensure focus wraps correctly.

Screen Reader Support

Use semantic output. Test with common readers (NVDA, JAWS). Provide text labels for non-text elements.

Anti-patterns to avoid

Relying on colour alone to convey information—always add text, icons, or patterns Missing focus indicators—make keyboard navigation invisible to users Audio/visual-only feedback—provide text alternatives for all signals
