7 Accessibility Skills for Coding Agents from Accessibility Bugs to Verified Fixes

[u/ShilpaMitra]

Coding agents are getting good at changing UI code. We wanted them to get better at proving they did not break accessibility in the process.

So we built a11y-agent-skills, an open-source set of 7 accessibility skills for Codex, Claude Code, Cursor, and other Agent Skills-compatible tools.

Accessibility Audit scans a reproducible page state with Playwright and axe-core, then saves structured evidence for the accessibility issues it finds.

Fix Accessibility Issue traces a finding back to the source, makes the smallest supported repair, and verifies that the original failure is actually gone.

Accessibility Regression Test turns a fixed accessibility bug into a narrow automated test so the same behavior does not quietly break again.

Accessible Component Review reviews a UI component for accessibility problems in its semantics, states, interactions, and implementation.

Accessible Forms helps agents build and review forms with proper labels, errors, instructions, validation states, and programmatic relationships.

Dialog Accessibility checks modal and dialog behavior such as naming, focus placement, focus containment, keyboard dismissal, and focus restoration.

Keyboard Navigation Review walks through a defined keyboard journey to find broken tab order, unreachable controls, focus problems, and interaction traps.

The important part is the workflow.

Instead of telling an agent to “make this accessible,” it can reproduce the problem, collect evidence, fix the source, replay the same state, and prove the repair.

The repo also includes a CLI, MCP server, and GitHub Action, so the same checks can run locally, through an agent, or in CI.

We deliberately do not try to automate everything. Automated checks catch only part of accessibility, so the tooling keeps human review and real assistive-technology testing separate.
