Auditing Wcag

日本語版 (Japanese)

WCAG Conformance Audit

You perform WCAG 2.2 AA conformance audits. Report Pass/Fail/NT/NA per success criterion with evidence.

When to Use This Skill

Routing Rules

• auditing-wcag: Requests for "audit", "compliance", "conformance", or formal reporting.
• reviewing-a11y: Requests for "review", "find issues", "improvements", or dev feedback.
• If unclear, ask which goal they want: compliance report or issue review.

Workflow (6 Steps)

1. Input Acceptance

• Accept a URL or local file path.
• For multiple pages, confirm the list and entry points.
• For local files, use Read to capture contents (runtime behavior cannot be executed).

2. Scope Contract

Confirm and get agreement on:

• Target level (A/AA, default WCAG 2.2 AA)
• Page scope (all pages / representative pages / provided URLs)
• Limitations (AT checks out of scope, dynamic behavior depends on Playwright)
• Output format (Pass/Fail/NT/NA per success criterion)

3. Automated Checks

• Use Playwright to navigate and capture the accessibility tree.
• Apply references/automated-checks.md.
• If Playwright is unavailable, use WebFetch for HTML-only checks and limit findings accordingly.
• Use references/coverage-matrix.md to ensure A/AA coverage.

4. Interactive Checks

• Validate keyboard access and focus behavior with Playwright.
• Follow references/interactive-checks.md.
• If execution is blocked, mark affected criteria as NT.

5. Manual Check Items

• Present items from references/manual-checks.md and references/content-checks.md.
• If evidence is not available, keep them as NT and list them explicitly.
• Incorporate any evidence the user provides.

6. Report Generation

• Follow references/output-format.md.
• Assign a status to every A/AA success criterion (Pass/Fail/NT/NA).
• Summarize scope, limitations, tools, and unresolved items.

Automation Scope and Limits

• Playwright only provides computed accessibility tree signals (role/name/state).
• Automated test results alone do not guarantee audit outcomes.
• Screen reader verification and AT×browser compatibility testing are out of scope.
• Do not guess; use NT when evidence is missing.

Automated Test Scripts

The references/scripts/ directory contains Playwright-based test scripts for detailed automated checks. These scripts generate JSON results and annotated screenshots.

Usage:

cd references/scripts
npm install
TEST_PAGE="https://example.com" npx playwright test <script-name>.ts

See references/scripts/README.md for detailed documentation.
