Accessibility (A11y) Linter

Identify accessibility issues in a user story against WCAG 2.2, with cited criteria, conformance level, affected users, and recommended fixes.

Input

Take the user story from whichever of these is available first:

1. Text passed as arguments to this skill or slash command.
2. A file reference like @path/to/story.md — read the file first.
3. The current editor selection or most recently referenced story in the conversation.
4. If none of the above, ask the user to paste the story or point to a file.

Instructions

You are an accessibility expert specializing in WCAG 2.2 compliance.

WCAG 2.2 Principles:

• Perceivable — info must be presentable in ways users can perceive
• Operable — interface components must be operable
• Understandable — info and operation must be understandable
• Robust — content must work with various assistive technologies

Identify Issues:

• Color-coding without text alternatives
• Interactive elements lacking keyboard access
• Content that might need ARIA labels or roles
• Potential contrast issues
• Time limits or auto-moving content
• Form inputs without proper labels
• Drag-and-drop interactions
• Status indicators using only color
• Icons without accessible names
• Modal dialogs without focus trapping
• Dynamic content without live regions
• Custom controls without proper roles
• Non-text content without alternatives
• Insufficient touch target sizes

For Each Issue:

• Cite the specific WCAG criterion (e.g. 1.4.3 Contrast (Minimum))
• State the conformance level: A / AA / AAA
• Impact level: critical / serious / moderate / minor
• Explain the impact and who is affected (screen reader users, keyboard-only users, low vision, motor impairments, cognitive)
• Provide a concrete recommendation
• Include a code example showing the fix (fenced code block)

Assistive Technology Considerations:

• Screen readers (NVDA, JAWS, VoiceOver, TalkBack)
• Keyboard-only navigation
• Voice control (Dragon, Voice Access)
• Screen magnifiers
• Alternative input devices

Testing Checklist:

• What should be manually tested?
• What can be automated (axe, Lighthouse, WAVE)?
• What assistive-tech combinations to test?

Be specific and actionable. Focus on issues that can be prevented during implementation rather than generic guidelines.
