Accessibility Auditor is a skill that performs structural and semantic analysis of frontend component code to check compliance with WCAG 2.2 AA standards. It accepts HTML, JSX (React), Vue templates, Svelte, and Angular templates, as well as common UI patterns such as modals, tabs, and comboboxes built with standard HTML5.
When an agent runs an audit, it receives a structured Accessibility Audit Report organized into three severity tiers: Critical, Major, and Minor. Each issue entry includes an impact analysis explaining how the problem affects screen readers and other assistive technology, remediation steps with direct code fixes, and a reference to the specific WCAG 2.2 success criterion involved — for example, 2.1.1 Keyboard or 1.1.1 Text Alternatives. The report also includes a conformance summary showing pass and failure counts against AA levels.
The types of issues the skill detects include missing ARIA roles, keyboard traps, low color contrast, and non-semantic heading hierarchies. The skill references axe-core, Lighthouse, and WAVE as external tools suitable for independently verifying findings.
This is a skill rather than an MCP server, so it extends an agent’s analysis capability without connecting to a live database or external service. It is most useful during code review or pre-production stages when a developer or automated agent needs actionable accessibility compliance reports from source code without running a browser.
