Tested accessibility skills, CLI, MCP server, and GitHub Action for agent-assisted audits and regression checks.
Find the regression, fix the source, prove the repair.
An open-source accessibility quality layer for teams building interfaces with AI. Seven portable Agent Skills guide coding agents through reproducible evidence, conservative source fixes, scoped verification, and durable regression tests. Framework-independent Playwright and axe-core packages provide the deterministic core; React is the first tested framework fixture.
Published core, CLI, and MCP packages support Node.js 20+. Run the CLI without cloning the repository:
To keep the command available locally, use npm install --global @a11y-agent/cli and run a11y-agent doctor.
For an MCP host, launch the stdio server with:
Building from source requires Node.js 22.13+ and pnpm 11.19. From a clone:
The fixture server prints its local URL. In another terminal, ask your coding agent:
Use accessibility-audit to audit the checkout state at http://127.0.0.1:4173/gallery-broken.html. Save JSON evidence to .a11y-agent/checkout-before.json.
The equivalent deterministic command is:
Review a fingerprint and its bounded DOM evidence, then ask:
Use fix-accessibility-issue to locate the source of this finding, make the smallest supported repair, replay checkout-invalid, verify the fingerprint is gone, and add the narrowest regression test.
The verification report records state reproduction, resolved and remaining fingerprints, new serious/critical findings, and exact run IDs. The regression test protects behavior such as an error being programmatically exposed—not merely the presence of one attribute.
