The Accessibility plugin audits against WCAG 2.1 AA using WCAG-EM, the W3C's evaluation methodology. You scope the audit, evaluate the pages, report the findings, remediate the issues and retest the fixes. Each phase writes a numbered file to .singularskills/accessibility/<target>/, ending with a conformance statement.

Artifact Flow

Each phase reads from previous phases and writes to .singularskills/accessibility/<target>/:

.singularskills/accessibility/checkout-flow/
  01-scope.md         ← Audit plan and scope
  02-evaluate.md      ← Issues with WCAG mapping
  03-report.md        ← Detailed findings report
  04-remediate.md     ← Remediation log
  05-retest.md        ← Conformance statement

The plugin targets WCAG 2.1 Level AA as the baseline, which satisfies:

Section 508 (US federal)
EN 301 549 (EU)
European Accessibility Act (EAA)

Cross-Domain Integration

The comprehensive WCAG criteria reference in this plugin's shared resources can be used by other domains — the Design plugin already references a subset for component-level accessibility checks.
