What the skill teaches
An official Chrome DevTools for agents skill for checking and fixing accessibility problems with the Chrome DevTools MCP server. It points the agent to a Lighthouse audit as a first pass, then to the accessibility tree from a page snapshot as the reliable view of what screen readers get. From there it walks through semantic markup, ARIA labels, focus and keyboard navigation, tap target size and colour contrast, drawing on web.dev guidance, which it suggests fetching as plain markdown. A references file holds ready-made JavaScript snippets for some of these checks.
Capabilities
- Run a Lighthouse accessibility audit
- Review the accessibility tree of a page
- Check focus order and keyboard navigation
