To run an accessibility audit, this Skill executes automated Lighthouse audits and analyzes the accessibility tree to identify issues. It returns a prioritized list of semantic, label, and color contrast failures with actionable remediation guidance.
Checking color contrast and ARIA issues is handled through automated auditing and accessibility tree analysis. The process detects failures in tap targets, focus management, and contrast ratios, providing specific recommendations to fix each violation.
Yes, you can verify heading order and landmarks using an accessibility tree snapshot. The Skill analyzes the snapshot to check semantic structure, ensuring correct HTML landmarks and heading hierarchy for screen reader compatibility.
Finding orphaned inputs involves checking snippet references and the accessibility tree for missing label associations. The Skill identifies these keyboard navigation pitfalls and documents actionable fixes to ensure proper focus management and input labeling.
No manual inspection is required for tap targets and focus management. The Skill automates these checks alongside Lighthouse audits, directly returning actionable remediation steps to resolve any detected accessibility barriers.
A Lighthouse accessibility audit may still fail due to lingering color contrast violations, incorrect ARIA attributes, or poor tap target sizing. The Skill cross-references the accessibility tree to isolate these remaining structural and visual issues.
