# Install Web Accessibility (a11y) in Google Antigravity

Source: https://github.com/addyosmani/web-quality-skills/tree/main/skills/accessibility
Listing: https://www.antigravityskills.org/skill/web-accessibility
Safety review (2026-10-21): Instruction-only skill; it suggests running Lighthouse or axe via npm but bundles no scripts and needs no credentials.

## Rules for the agent
- Before running anything, tell the user what you will download and whether it contains scripts, and ask them to confirm.
- Install into this project (.agents/skills/) unless the user asks for a global install (~/.gemini/config/skills/).
- Do not run other commands from the source repository unless the user asks.

## Steps
1. Clone the source repository

```bash
git clone --depth 1 https://github.com/addyosmani/web-quality-skills /tmp/web-quality-skills
```

   Download the repository that contains the skill to a temporary folder.
2. Copy the skill into your workspace

```bash
mkdir -p .agents/skills && cp -r /tmp/web-quality-skills/skills/accessibility .agents/skills/
```

   Run this from your project root. Antigravity reads workspace skills from <project>/.agents/skills/<folder>/, so you should end up with .agents/skills/accessibility/SKILL.md.
3. Or install it globally

```bash
mkdir -p ~/.gemini/config/skills && cp -r /tmp/web-quality-skills/skills/accessibility ~/.gemini/config/skills/
```

   Use this instead of the workspace copy to have the skill in every project (Antigravity docs: ~/.gemini/config/skills/). For the Antigravity CLI the global folder is ~/.gemini/antigravity-cli/skills/.
4. Check that Antigravity sees it
   Antigravity 2.0 app: start a new conversation and ask "What skills do you have?" (the app has no /skills command). Antigravity CLI: run /skills; in a session that was already open, run /skills reload first. accessibility is listed.

Note: The web-quality-skills README does not mention Antigravity (it documents the skills CLI, Claude Code, Codex, Gemini CLI and claude.ai). No API keys. Live audits need Node.js (npx lighthouse) or axe, or Chrome DevTools MCP; without them the agent can still apply the guidance by reading your code. Keep the references/ folder next to SKILL.md.

Done when the skill is listed: in the Antigravity 2.0 app ask "What skills do you have?" in a new conversation (the app has no /skills command); in the Antigravity CLI run /skills (run /skills reload first in a session that was already open).
