accessibility-reviewRun a WCAG 2.1 AA accessibility audit on a design or page. An agent skill from markmead/hyperui.
Accessibility Review is an agent skill from markmead/hyperui. Run a WCAG 2.1 AA accessibility audit on a design or page. Trigger with "audit accessibility", "check a11y", "is this accessible?", or when reviewing a design for color contrast, keyboard navigation, touch target size, or screen reader behavior before handoff.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Accessibility. It works with Tailwind CSS. The repository describes itself as: Free Tailwind CSS v4 components for your next project, designed to enhance your web development with the latest features and styles 🚀. The licence is MIT.
8 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 2b5aebb. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Accessibility Review loads about 1.1k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 291 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.
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.

Run a WCAG 2.1 AA accessibility audit on a design or page. An agent skill from markmead/hyperui. Accessibility Review is an agent skill from markmead/hyperui.1 AA accessibility audit on a design or page.
Accessibility Review fits situations like: with audit accessibility; is this accessible?; reviewing a design for color contrast; keyboard navigation.
Run `npx skills add markmead/hyperui --skill accessibility-review -a claude-code`. Or copy the skill folder (.agents/skills/accessibility-review in markmead/hyperui) into .claude/skills/accessibility-review in your project. Claude Code loads it when a task matches its description.
Run `npx skills add markmead/hyperui --skill accessibility-review -a codex`. Or copy the skill folder (.agents/skills/accessibility-review in markmead/hyperui) into .agents/skills/accessibility-review in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add markmead/hyperui --skill accessibility-review -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-review, .gemini/skills/accessibility-review, .github/skills/accessibility-review and .opencode/skills/accessibility-review in your project.
SKILL.md names no scripts, command-line tools or credentials: Accessibility Review is instructions for the agent only.
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.
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.
Accessibility Review is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Accessibility Review: Baseline UI (ibelick/ui-skills, 9.6k stars), UI/UX Design System Advisor (Galaxy-Dawn/claude-scholar, 5.7k stars), Extract Design (Manavarya09/design-extract, 4.2k stars) and Better Colors (trycompai/crm, 11k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
