qa-accessibility
Atomic accessibility coverage: WCAG 2.2 keyboard + focus-trap + contrast + ARIA references, the full manual-a11y artifact surface (screen-reader scripts, checklists, widget matrices, guided sessions), the a11y violation gate, an adversarial code critic, the axe-a11y scanner umbrella (axe-core / pa11y / Lighthouse a11y / WAVE / IBM Equal Access), and a WCAG conformance reporter.
Components
| Type | Name | Description |
|---|---|---|
| Skill | wcag-keyboard-navigation | WCAG 2.2 keyboard SCs (2.1.1, 2.1.2, 2.1.4, 2.4.3, 2.4.7, 2.4.11) with per-criterion test scripts; modal focus-trap pattern in references/. |
| Skill | wcag-color-contrast | WCAG 2.2 SCs 1.4.3/1.4.6/1.4.11/1.4.13; canonical ratios; design-token bulk checking. |
| Skill | aria-authoring-patterns | W3C ARIA Authoring Practices Guide reference for the 31 widget patterns. |
| Skill | screen-reader-test-author | The manual-a11y artifact surface: NVDA / JAWS / VoiceOver / TalkBack test scripts, per-archetype WCAG checklists, per-widget keystroke matrices, and guided signed sessions. |
| Skill | a11y-violation-gate | CI gate with ratchet pattern: fail on new violations vs. baseline; aggregate axe / pa11y / Lighthouse / WAVE / IBM Equal Access. |
| Skill | axe-a11y | Automated accessibility scanning umbrella: axe-core primary (JS API, @axe-core/playwright, tags, rule disable); pa11y, Lighthouse a11y, WAVE, and IBM Equal Access in references/. |
| Skill | wcag-compliance-reporter | Build-an-X per-page WCAG 2.2 conformance report aggregating multi-scanner output; per-SC + per-level rollup; "unknown" verdict for SCs no tool covers. |
| Agent | accessibility-code-critic | Adversarial source-code review for <div onclick>, missing focus mgmt, color-only cues, ARIA misuse; cites WCAG SC + remediation. |

a11y-violation-gate
Builds a CI gate that fails the build on **new** WCAG / a11y violations introduced by a PR while grandfathering pre-existing violations on a per-rule / per-page baseline. Aggregates verdicts from axe-core / pa11y / Lighthouse a11y / WAVE / IBM Equal Access scans. Use when a project has accumulated a11y debt and a strict "zero violations" gate would block every PR - the ratchet pattern lets the team ship while preventing regressions.
aria-authoring-patterns
Reference for the W3C ARIA Authoring Practices Guide (APG) - covers the 31 canonical interactive-widget patterns (Combobox, Dialog, Menu, Tabs, Tree, etc.), their required ARIA roles and states, the keyboard-interaction model per pattern, and the canonical-violations to watch for. Use when authoring a custom interactive widget that doesn't have a native HTML equivalent, or when reviewing one for ARIA correctness.
axe-a11y
Automated accessibility scanning across the five engines - axe-core (primary), pa11y, Lighthouse a11y, WAVE, and IBM Equal Access. Authors and runs axe-core scans via the `axe.run()` JavaScript API or the @axe-core/playwright / @axe-core/cli wrappers, parses `violations[]` into per-rule severity, configures rule disable / disable-by-tag patterns, and emits CI-gateable output; references/ carry the pa11y CLI (htmlcs + axe runners), Lighthouse CI `categories:accessibility` assertions, the WAVE API / overlay, and IBM Equal Access (Section 508) with their verified CLI / API / config. Use for any automated a11y scanner setup - axe-core for JS/TS UI test suites on every PR, and the references for CLI-only, Lighthouse-pipeline, WebAIM-branded, or Section 508 scanning.
screen-reader-test-author
Builds the full manual-accessibility artifact surface: step-by-step screen-reader test scripts for NVDA (Windows), JAWS (Windows), VoiceOver (macOS / iOS), or TalkBack (Android) with per-step keystroke + expected announcement; per-archetype WCAG 2.2 checklists (references/wcag-checklist.md); per-widget keystroke matrices pairing expected NVDA and VoiceOver announcements with the WCAG SC each row verifies (references/widget-matrix.md); and a guided NVDA / VoiceOver session protocol that merges script + checklist into a signed pass/fail session report. Use when authoring an accessibility-acceptance test, checklist, or widget matrix the team will run before sign-off, when scripting a manual a11y audit, OR when walking a tester through a guided screen-reader session.
wcag-color-contrast
Reference for WCAG 2.2 color-contrast conformance - covers SC 1.4.3 Contrast (Minimum, AA), 1.4.6 Contrast (Enhanced, AAA), 1.4.11 Non-text Contrast (AA), and 1.4.13 Content on Hover or Focus (AA) - with the canonical contrast ratios (4.5:1 normal text, 3:1 large text and UI components), measurement formula references, and bulk design-token checking patterns. Use when designing a color palette, reviewing a component for accessibility, or auditing existing CSS for contrast violations.
wcag-compliance-reporter
Builds a per-page WCAG 2.2 compliance score report by aggregating output from one or more accessibility scanners (axe-core / pa11y / lighthouse / WAVE / IBM Equal Access), pivoting violations by Success Criterion (1.4.3 contrast, 2.4.7 focus visible, etc.), grouping by conformance level (A / AA / AAA), reporting per-page coverage gaps explicitly (the "this page wasn't scanned" failure mode), and emitting both an executive summary and a per-page drill-down. Use after a multi-page accessibility scan - pa11y-ci, axe across a sitemap, lighthouse-batch - when the team needs a shareable conformance report rather than a per-page tool dump.
wcag-keyboard-navigation
Reference catalog for WCAG 2.2 keyboard-navigation conformance - covers SC 2.1.1 (Keyboard), 2.1.2 (No Keyboard Trap), 2.1.4 (Character Key Shortcuts), 2.4.3 (Focus Order), 2.4.7 (Focus Visible), 2.4.11/2.4.12 (Focus Not Obscured) - with conformance levels (A/AA), test scripts, and per-criterion failure patterns, plus the modal focus-trap / focus-management pattern (focus-on-open, Tab-cycle, inert, Escape-closes, restore-to-trigger, native `<dialog>`) in references/. Use when authoring or reviewing keyboard-only interaction support, or a modal / drawer / popover's focus management.
