Installation

A skill is a folder with a SKILL.md file. Pick your agent and run the commands in a terminal (macOS, Linux or Git Bash on Windows) from your project root.

Copy the prompt into Claude, Codex or another assistant: it will review the skill and install it for you.

Install the “wcag-audit-patterns” skill from mozgi.io (https://mozgi.io/skills/wshobson-wcag-audit-patterns/) for me.

1. Download the archive: https://mozgi.io/skills/wshobson-wcag-audit-patterns/download
   If it fails, take the skill folder from the source: https://github.com/wshobson/agents/tree/main/plugins/accessibility-compliance/skills/wcag-audit-patterns
2. Read SKILL.md and the other files. Check the skill is safe: no hidden commands, no sending data elsewhere, no scripts doing something other than described. If anything looks suspicious, stop and tell me.
3. Put the “wcag-audit-patterns” folder into your agent's skills folder: .claude/skills/ for Claude Code, .agents/skills/ for Codex, .cursor/skills/ for Cursor, .gemini/skills/ for Gemini CLI. Inside the project if we are in one, otherwise in the home folder (~/.claude/skills/ etc.).
4. Make sure <skills folder>/wcag-audit-patterns/SKILL.md exists.
5. Briefly tell me what this skill does and offer to try it on my task.

If you cannot do a step yourself, tell me what to click or type.

git clone --depth 1 --branch main https://github.com/wshobson/agents.git /tmp/agents
mkdir -p .claude/skills
cp -r /tmp/agents/plugins/accessibility-compliance/skills/wcag-audit-patterns .claude/skills/wcag-audit-patterns

Restart Claude Code — the skill appears in the list; call it manually with /wcag-audit-patterns. For all projects use ~/.claude/skills.

git clone --depth 1 --branch main https://github.com/wshobson/agents.git /tmp/agents
mkdir -p .agents/skills
cp -r /tmp/agents/plugins/accessibility-compliance/skills/wcag-audit-patterns .agents/skills/wcag-audit-patterns

Codex looks for skills in .agents/skills from the current folder up to the repo root; call one with /skills or $wcag-audit-patterns. For all projects use ~/.agents/skills.

git clone --depth 1 --branch main https://github.com/wshobson/agents.git /tmp/agents
mkdir -p .cursor/skills
cp -r /tmp/agents/plugins/accessibility-compliance/skills/wcag-audit-patterns .cursor/skills/wcag-audit-patterns

Cursor picks the skill up on start; call it with “/” in Agent chat. Cursor also reads .claude/skills and .agents/skills. For all projects use ~/.cursor/skills.

git clone --depth 1 --branch main https://github.com/wshobson/agents.git /tmp/agents
mkdir -p .gemini/skills
cp -r /tmp/agents/plugins/accessibility-compliance/skills/wcag-audit-patterns .gemini/skills/wcag-audit-patterns

Gemini CLI offers to activate the skill when a task matches — you approve it. For all projects use ~/.gemini/skills.

WCAG Audit Patterns

Comprehensive guide to auditing web content against WCAG 2.2 guidelines with actionable remediation strategies.

When to Use This Skill

Conducting accessibility audits
Fixing WCAG violations
Implementing accessible components
Preparing for accessibility lawsuits
Meeting ADA/Section 508 requirements
Achieving VPAT compliance

Core Concepts

1. WCAG Conformance Levels

| Level | Description | Required For |

| ------- | ---------------------- | ----------------- |

| A | Minimum accessibility | Legal baseline |

| AA | Standard conformance | Most regulations |

| AAA | Enhanced accessibility | Specialized needs |

2. POUR Principles

Perceivable:  Can users perceive the content?
Operable:     Can users operate the interface?
Understandable: Can users understand the content?
Robust:       Does it work with assistive tech?

3. Common Violations by Impact

Critical (Blockers):
├── Missing alt text for functional images
├── No keyboard access to interactive elements
├── Missing form labels
└── Auto-playing media without controls

Serious:
├── Insufficient color contrast
├── Missing skip links
├── Inaccessible custom widgets
└── Missing page titles

Moderate:
├── Missing language attribute
├── Unclear link text
├── Missing landmarks
└── Improper heading hierarchy

Detailed patterns and worked examples

Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.

Best Practices

Do's

Start early - Accessibility from design phase
Test with real users - Disabled users provide best feedback
Automate what you can - 30-50% issues detectable
Use semantic HTML - Reduces ARIA needs
Document patterns - Build accessible component library

Don'ts

Don't rely only on automated testing - Manual testing required
Don't use ARIA as first solution - Native HTML first
Don't hide focus outlines - Keyboard users need them
Don't disable zoom - Users need to resize
Don't use color alone - Multiple indicators needed

Frequently asked questions

What does the wcag-audit-patterns skill do?

How do I install wcag-audit-patterns?

Open the “Installation” block on this page and pick your agent — Claude Code, Codex, Cursor or Gemini CLI — for ready-made commands that copy the skill folder to the right place. Or copy the prompt from the “Via assistant” tab and let the assistant review and install the skill.

Which AI models work with wcag-audit-patterns?

Skills are plain Markdown instructions (the Agent Skills format), so wcag-audit-patterns works with any agent that reads SKILL.md: Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and more. The model loads the instructions only when a task matches the skill's description.

Is wcag-audit-patterns free?

The skill is published openly by wshobson under the MIT license. The skill itself costs nothing — you only pay your AI provider for the tokens you use.

Is it safe to install skills?

A skill is a set of instructions your agent will follow, so read SKILL.md and its companion files before installing. Scripts in the skill folder only run if your agent runs them — keep an eye on what it does and do not grant unnecessary permissions.

How is a skill different from an MCP server or a plugin?

An MCP server or plugin gives the model new tools — code that runs and returns a result. A skill gives it knowledge and process: how to approach a task, which steps to follow and what good output looks like. It needs no server or API key.
