Accessibility Agents

AI and automated tools are not perfect. They miss things, make mistakes, and cannot replace testing with real screen readers and assistive technology. Always verify with VoiceOver, NVDA, JAWS, and keyboard-only navigation. This tooling is a helpful starting point, not a substitute for real accessibility testing.

A community-driven open-source project automating accessibility, efficiency, and productivity through AI-based agents, skills, custom instructions, and prompts.

A sincere thanks goes out to Taylor Arndt and Jeff Bishop for leading the charge in building this community project. It started because LLMs consistently forget accessibility - skills get ignored, instructions drift out of context, ARIA gets misused, focus management gets skipped, color contrast fails silently. They got tired of fighting it and built an agent team that will not let it slide. Now we want to make more magic together.

We want more contributors! If you care about making software accessible to blind and low vision users, please consider submitting a PR. Every improvement to these agents helps developers ship more inclusive software for the people who need it most.

The Problem

AI coding tools generate inaccessible code by default. They forget ARIA rules, skip keyboard navigation, ignore contrast ratios, and produce modals that trap screen reader users. Even with skills and CLAUDE.md instructions, accessibility context gets deprioritized or dropped entirely.

The Solution

Accessibility Agents provides seventy-nine specialized agents across eight teams and five platforms:

• Web Accessibility team - agents that enforce WCAG AA standards for web code, including i18n/RTL, WCAG AAA coverage, data visualization, email, media, web components, and performance accessibility
• Document Accessibility team - agents for Office (DOCX, XLSX, PPTX), PDF, EPUB, and Markdown accessibility scanning and remediation
• GitHub Workflow team - twenty agents that manage repositories, triage issues, review PRs, manage project boards, CI/CD workflows, security alerts, releases, notifications, and wiki pages
• Developer Tools team - agents for Python, wxPython, desktop accessibility, NVDA addon development, and accessibility tool building
• Education & Standards - screen reader simulation, WCAG 3.0 preview, WCAG AAA auditing
• Cross-cutting - CI/CD accessibility pipelines, compliance mapping, accessibility statements, regression detection, and orchestrators that route work across teams

All agents run on:

• Claude Code - Agents you invoke directly for accessibility evaluation
• GitHub Copilot (VS Code and CLI) - Agents + workspace instructions that ensure accessibility guidance in every conversation
• Gemini CLI - Skills-based extension with always-on WCAG AA context via GEMINI.md
• Codex CLI - Stable .codex/AGENTS.md baseline plus optional experimental TOML-based roles for focused accessibility passes
• MCP Server - HTTP-based server providing 24 accessibility scanning tools to any MCP-compatible client (Claude Desktop, VS Code, CI/CD pipelines)

System Requirements

⚠️ CRITICAL: To remain current with Accessibility Agents and ensure proper functionality, you must keep all tools updated to their latest versions. New platform capabilities, API changes, accessibility features, and bug fixes directly impact agent behavior.
