Check out our new developer guide for Getting Started with GitHub Copilot Custom Agents for Accessibility. It walks you through creating specialized Copilot agents that automate accessibility tasks in your development workflow, from auditing pages with axe-core to tracking accessibility improvements across releases.

What you'll learn

• How to build custom agents that handle focused, repeatable accessibility workflows using agent definition files with targeted tool access and domain-specific instructions.
• Practical examples including an Accessibility Tracker agent and a Markdown Accessibility Assistant, built step by step so you can adapt the patterns to your own team's needs.

Why it matters
Custom agents let you encode your team's accessibility expertise into reusable assistants that anyone can invoke on demand. They help scale the work your accessibility experts are already doing, so best practices are applied consistently across the team. Fewer issues slip through, new team members ramp up faster, and accessible development becomes part of your everyday workflow rather than an afterthought.
