Accessibility Design
Overview
Use this skill to define concrete accessibility behavior that implementation teams can build and verify without ambiguity.
Scope Boundaries
- Accessibility behavior for flows or components is undefined or inconsistent.
- Teams need implementation-ready accessibility requirements before release.
- Design changes risk keyboard, screen-reader, or readability regressions.
Templates And Assets
- Accessibility spec template:
assets/accessibility-spec-template.md
- Accessibility review checklist:
assets/accessibility-review-checklist.md
Inputs To Gather
- Critical user journeys and high-risk interaction points.
- Existing accessibility defects and known constraints.
- Platform scope and assistive technology targets.
- Required policy/baseline level for the project.
Deliverables
- Accessibility spec per flow/component (semantics, interaction, feedback).
- Prioritized defect/remediation list with user impact.
- Verification checklist for design review and implementation QA.
- Residual risk log for unresolved issues.
Workflow
- Identify critical journeys and map accessibility-sensitive interactions.
- Specify semantic roles, labels, headings, and landmark expectations.
- Define keyboard behavior, focus order, and focus visibility rules.
- Define readable visual behavior (contrast, scaling, non-color cues).
- Define assistive-technology announcements for dynamic state changes.
- Validate requirements against testability and implementation feasibility.
Quality Standard
- Interaction semantics are explicit for all actionable elements.
- Keyboard and focus behavior is fully specified across states.
- Error and status feedback is perceivable and understandable.
- Requirements are testable with manual and automated checks.
Failure Conditions
- Stop when critical journeys lack explicit accessibility behavior.
- Stop when requirements are non-testable in target environments.
- Escalate when unresolved critical accessibility issues block safe release.
