Is the Accessibility skill free?

Yes. The skill itself is free from addyosmani/web-quality-skills. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Accessibility SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Accessibility?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Accessibility with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

What Accessibility does

A self-contained WCAG 2.2 accessibility reference that guides audits and fixes across contrast, ARIA, keyboard nav, focus, and target size. Triggers on requests like "a11y audit", "WCAG compliance", "make accessible", "screen reader support", or "keyboard navigation". Adds concrete criterion numbers and correct patterns a baseline tends to gloss over.

How to install Accessibility

Copy skills/accessibility/ (including references/) into ~/.claude/skills/ or .claude/skills/ in your project.
