What problem does it solve? Accessibility barriers are hard to confirm and reproduce: automated scanners report findings without context, and manual keyboard or screen reader issues often go undetected until users complain. This Skill provides a structured debugging workflow to confirm, reproduce, and document accessibility defects with evidence. ## Core Features & Use Cases - Structured Debug Workflow: Reproduce the barrier, inspect role/name/state/value in the accessibility tree, run automation, and verify with keyboard and screen reader smoke checks. - Tooling Checklist: A repeatable checklist covering automated finding confirmation, accessibility tree inspection, keyboard contracts, screen reader smoke paths, custom CSS/JS debug rules, and CI gates. - Regression Prevention: Guidance on adding focused regression coverage and CI gates that block new Critical/High accessibility regressions. - Use Case: A scanner flags a modal dialog for missing focus management. Use this Skill to confirm the defect in the accessibility tree, verify keyboard trap behavior, run a screen reader smoke test, and produce a defect report with reproduction steps and fix direction. ## Quick Start Debug the accessibility issue on the checkout page by inspecting the accessibility tree, testing keyboard navigation, and confirming the defect with a screen reader smoke check.
