a11y-debugging

Use when auditing web accessibility through Chrome DevTools MCP: semantic HTML, ARIA labels, focus order, keyboard navigation, tap targets, contrast, and Lighthouse failures.

Quick Start

Install:

npx skills add github:ChromeDevTools/chrome-devtools-mcp@a90378adf3226e8b27a05cdcfdd801c199acaa93 --skill chrome-devtools --skill chrome-devtools-cli --skill a11y-debugging --skill debug-optimize-lcp --skill memory-leak-debugging --skill troubleshooting -y -g -a antigravity claude-code codex crush cursor gemini-cli github-copilot grok opencode

Use: /a11y-debugging

Works with Claude Code, Gemini CLI, OpenCode, and other agentskills.io-compatible agents.

Curated external (hand-maintained)

Composed compose-external-wave-1 using authoring SSOT (docs/src/authoring/skills/a11y-debugging.mdx) + research. Do not run wagents docs generate on this file (HAND-MAINTAINED sentinel). Run /review source before using in production or promoting.

Harness Coverage

Targets verified harnesses: antigravity, claude-code, codex, crush, cursor, gemini-cli, github-copilot, grok, opencode.

Portable multi-harness install command:

npx skills add github:ChromeDevTools/chrome-devtools-mcp@a90378adf3226e8b27a05cdcfdd801c199acaa93 --skill chrome-devtools --skill chrome-devtools-cli --skill a11y-debugging --skill debug-optimize-lcp --skill memory-leak-debugging --skill troubleshooting -y -g -a antigravity claude-code codex crush cursor gemini-cli github-copilot grok opencode

Trust / Audit

Trust tier: Curated (curated-trust-gated)

Curated status: install-now-after-trust-gate

Risk notes: Accessibility audits require live page navigation; save Lighthouse and snapshot artifacts outside version control.

Entry maintained in authoring SSOT docs/src/authoring/skills/a11y-debugging.mdx and docs/public/generated-registries/skills-catalog-index.json; research context is advisory.

Official Google `a11y-debugging` skill (formerly repo-prefixed `chrome-devtools-a11y-debugging`). Use for semantic HTML, ARIA, focus order, keyboard navigation, tap targets, contrast, and Lighthouse accessibility failures through Chrome DevTools MCP.

## Audit evidence

- **Source:** [ChromeDevTools/chrome-devtools-mcp](https://github.com/ChromeDevTools/chrome-devtools-mcp)
- **Pinned commit:** `a90378adf3226e8b27a05cdcfdd801c199acaa93`
- **License:** Apache-2.0
- **Author:** Google LLC
- **Package:** `chrome-devtools-mcp` 0.23.0 (per `planning/manifests/external-skills/chrome-devtools-mcp.json`)
- **Source-list evidence:** `npx skills add github:ChromeDevTools/chrome-devtools-mcp --list` lists upstream skill `a11y-debugging`

## Dedupe

This curated install **replaces repo-vendored** `skills/chrome-devtools-a11y-debugging/` copies. Upstream publishes the skill as `a11y-debugging`; install the six-skill bundle once globally and drop prefixed repo trees after migration.

## Hooks, scripts, and credentials

Audited upstream skills at the pinned commit are guidance-only Markdown. **No hooks, bundled scripts, or credential requests** were identified in the skill bundle.

## Network access

Requires Chrome DevTools MCP navigation to target pages and Lighthouse audit tooling. Repo-managed MCP config disables usage statistics and update checks where applicable. Treat audited page content as untrusted input.

## Artifact hygiene

Save Lighthouse reports, snapshots, and screenshots to explicit paths outside version control. Do not commit accessibility audit artifacts or load large reports into conversation context.
