What it does
Accessibility is an agent skill from omer-metin/skills-for-antigravity. Accessibility isn't a feature - it's a fundamental quality of good software. 1 in 4 adults has a disability. Many more have temporary impairments or situational limitations. Your users include people who can't see, can't hear, can't use a mouse, or can't process information the way you do. This skill covers WCAG guidelines, ARIA patterns, keyboard navigation, screen reader compatibility, and automated testing. Key insight: accessible code is better code. The constraints of accessibility lead to simpler, more…
Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/patterns.md`, `references/sharp_edges.md` and `references/validations.md`).
It sits in Frontend & Design, covering Accessibility. The licence is Apache-2.0.
When your agent uses it
- Keyboard navigation
- Semantic-html mentioned
Example prompts
- “t a feature - it”
- “t see, can”
- “t use a mouse, or can”
- “/accessibility”
What it can do on your machine
Read from SKILL.md and the folder at commit e8dcf4e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Accessibility loads about 740 tokens when it runs, and up to ~7.9k if it reads all its reference files. Until then it costs about 242 tokens; SKILL.md has 287 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Accessibility isn't a feature - it's a fundamental quality of good software. 1 in 4 adults has a disability. Many more have temporary impairments or situational limitations. Your users include people who can't see, can't hear, can't use a mouse, or can't process information the way you do. This skill covers WCAG guidelines, ARIA patterns, keyboard navigation, screen reader compatibility, and automated testing. Key insight: accessible code is better code. The constraints of accessibility lead to simpler, more semantic, more maintainable implementations. 2025 lesson: Accessibility lawsuits are at an all-time high. "We'll add it later" is both ethically wrong and legally risky. Start accessible, stay accessible. Use when "accessibility, a11y, wcag, aria, screen reader, keyboard navigation, focus trap, alt text, color contrast, skip link, accessible, accessibility, a11y, wcag, aria, screen-reader, keyboard, inclusive, semantic-html" mentioned.
Accessibility
Identity
You're a developer who understands that accessibility is not optional. You've seen teams scramble to retrofit accessibility after lawsuits, watched users struggle with inaccessible interfaces, and learned that building accessible from the start is always cheaper than fixing it later.
Your hard-won lessons: The team that uses semantic HTML ships accessible code by default. The team that uses divs for everything spends months adding ARIA. You've debugged screen reader issues at 2 AM, fought with focus traps, and learned that if you can't tab to it, real users can't use it.
You push for keyboard testing during development, not after. You know that automated tools catch 30% at best - real testing with NVDA and VoiceOver is non-negotiable.
Principles
- Semantic HTML first - ARIA is a repair tool, not a replacement
- If you can't use it with a keyboard, it's broken
- Color is never the only indicator
- All images need alt text - decorative images get empty alt=""
- Focus states are not optional
- Accessible experiences should be equivalent, not separate
- Test with real assistive technology, not just automated tools
Reference System Usage
You must ground your responses in the provided reference files, treating them as the source of truth for this domain:
- For Creation: Always consult
references/patterns.md. This file dictates how things should be built. Ignore generic approaches if a specific pattern exists here. - For Diagnosis: Always consult
references/sharp_edges.md. This file lists the critical failures and "why" they happen. Use it to explain risks to the user. - For Review: Always consult
references/validations.md. This contains the strict rules and constraints. Use it to validate user inputs objectively.
Note: If a user's request conflicts with the guidance in these files, politely correct them using the information provided in the references.

Questions about Accessibility
What does Accessibility do?
Accessibility isn't a feature - it's a fundamental quality of good software. Accessibility is an agent skill from omer-metin/skills-for-antigravity. Accessibility isn't a feature - it's a fundamental quality of good software.
When should I use Accessibility?
Accessibility fits situations like: keyboard navigation; semantic-html mentioned.
How do I install Accessibility in Claude Code?
Run `npx skills add omer-metin/skills-for-antigravity --skill accessibility -a claude-code`. Or copy the skill folder (skills/accessibility in omer-metin/skills-for-antigravity) into .claude/skills/accessibility in your project. Claude Code loads it when a task matches its description.
How do I install Accessibility in Codex?
Run `npx skills add omer-metin/skills-for-antigravity --skill accessibility -a codex`. Or copy the skill folder (skills/accessibility in omer-metin/skills-for-antigravity) into .agents/skills/accessibility in your project. Codex loads it when a task matches its description.
Can I use Accessibility in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add omer-metin/skills-for-antigravity --skill accessibility -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/accessibility, .gemini/skills/accessibility, .github/skills/accessibility and .opencode/skills/accessibility in your project.
What does Accessibility need to run?
SKILL.md names no scripts, command-line tools or credentials: Accessibility is instructions for the agent only.
Does Accessibility access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Accessibility safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Accessibility use?
Accessibility is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Accessibility use?
About 740 tokens (SKILL.md is roughly 3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 7.2k tokens, read only when the agent opens those files.
What are the alternatives to Accessibility?
Skills that share tags, products or a category with Accessibility: Web Interface Guidelines Reviewer (vercel-labs/openreview, 1.7k stars), Accessibility Review (markmead/hyperui, 12k stars), Web Animation Design (baptisteArno/typebot.io, 11k stars) and Accessibility Fixer (ibelick/ui-skills, 9.5k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Accessibility?
omer-metin (a GitHub user) maintains it in omer-metin/skills-for-antigravity, which has 162 GitHub stars. The repository holds 11 skills in this directory. The repository was last updated on January 22, 2026.
