design-accessibility

name	design-accessibility
description	WCAG AA and ARIA best practices — screen readers, keyboard navigation, focus management. Use when building any user-facing interface or reviewing accessibility compliance.

Principles

• Use semantic HTML first — ARIA is a last resort, not a first tool
• Proper heading hierarchy — one h1 per page, never skip levels
• Alt text on all meaningful images
• Maintain 4.5:1 minimum color contrast ratio
• Use <button> for actions, <a> for navigation — never a styled <div>

Rules

See rules index for detailed patterns.

Examples

Positive Trigger

User: "Audit this form for WCAG AA issues and keyboard traps."

Expected behavior: Use design-accessibility guidance, follow its workflow, and return actionable output.

Non-Trigger

User: "Optimize SQL indexes for this analytics query."

Expected behavior: Do not prioritize design-accessibility; choose a more relevant skill or proceed without it.

Troubleshooting

Skill Does Not Trigger

• Error: The skill is not selected when expected.
• Cause: Request wording does not clearly match the description trigger conditions.
• Solution: Rephrase with explicit domain/task keywords from the description and retry.

Guidance Conflicts With Another Skill

• Error: Instructions from multiple skills conflict in one task.
• Cause: Overlapping scope across loaded skills.
• Solution: State which skill is authoritative for the current step and apply that workflow first.

Output Is Too Generic

• Error: Result lacks concrete, actionable detail.
• Cause: Task input omitted context, constraints, or target format.
• Solution: Add specific constraints (environment, scope, format, success criteria) and rerun.

Workflow

1. Identify whether the request clearly matches design-accessibility scope and triggers.
2. Apply the skill rules and referenced guidance to produce a concrete result.
3. Validate output quality against constraints; if gaps remain, refine once with explicit assumptions.
