If Connectors Available

If ~~design tool is connected:

Inspect color values, font sizes, and touch targets directly from Figma
Check component ARIA roles and keyboard behavior in the design spec

If ~~project tracker is connected:

Create tickets for each accessibility finding with severity and WCAG criterion
Link findings to existing accessibility remediation epics

Tips

Start with contrast and keyboard — These catch the most common and impactful issues.
Test with real assistive technology — My audit is a great start, but manual testing with VoiceOver/NVDA catches things I can’t.
Prioritize by impact — Fix issues that block users first, polish later.

About this skill

Trigger

Run a WCAG 2.1 AA accessibility audit on a design or page. Trigger with "audit accessibility", "check a11y", "is this accessible?", or when reviewing a design for color contrast, keyboard navigation, touch target size, or screen reader behavior before handoff.

How this issue was made

Source

github.com/anthropics/knowledge-work-plugins, branch main, last pushed 23 September 2026.

Licence

Apache-2.0 — the text of every skill is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

200 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. 27 distinct layouts observed: bio-research/skills/*/SKILL.md, cowork-plugin-management/skills/*/SKILL.md, customer-support/skills/*/SKILL.md, data/skills/*/SKILL.md, design/skills/*/SKILL.md, engineering/skills/*/SKILL.md, enterprise-search/skills/*/SKILL.md, finance/skills/*/SKILL.md, human-resources/skills/*/SKILL.md, legal/skills/*/SKILL.md, marketing/skills/*/SKILL.md, operations/skills/*/SKILL.md, partner-built/apollo/skills/*/SKILL.md, partner-built/brand-voice/skills/*/SKILL.md, partner-built/common-room/skills/*/SKILL.md, partner-built/slack/skills/*/SKILL.md, partner-built/zoom-plugin/skills/*/SKILL.md, partner-built/zoom-plugin/skills/contact-center/*/SKILL.md, partner-built/zoom-plugin/skills/meeting-sdk/*/SKILL.md, partner-built/zoom-plugin/skills/meeting-sdk/web/*/SKILL.md, partner-built/zoom-plugin/skills/video-sdk/*/SKILL.md, partner-built/zoom-plugin/skills/virtual-agent/*/SKILL.md, partner-built/zoom-plugin/skills/zoom-mcp/*/SKILL.md, pdf-viewer/skills/*/SKILL.md, product-management/skills/*/SKILL.md, productivity/skills/*/SKILL.md, sales/skills/*/SKILL.md.

Issue colours

Resolved from the awesome-design-md registry — hue 39°, chroma 0.113. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Typefaces

Display: Copernicus is not available to us; set in Newsreader.

We never load a typeface at request time from a third-party origin, so a brand face we do not already self-host is substituted rather than fetched.

Heading repairs

1 repair applied to this skill so the document has one h1 and no skipped levels:

Removed “/accessibility-review”, a leading h1 that duplicated the skill title.

Spec compliance

53 editorial notes across 41 of 200 skills. They are printed in the margin of each skill rather than as errors here.

and 31 more.

Images

Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .claude-plugin/marketplace.json by Anthropic, declaring 120 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /anthropics/knowledge-work-plugins.md, and each skill at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.

If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md (opens in a new tab).

WCAG 2.1 AA Quick Reference

Perceivable

1.1.1 Non-text content has alt text
1.3.1 Info and structure conveyed semantically
1.4.3 Contrast ratio >= 4.5:1 (normal text), >= 3:1 (large text)
1.4.11 Non-text contrast >= 3:1 (UI components, graphics)

Operable

2.1.1 All functionality available via keyboard
2.4.3 Logical focus order
2.4.7 Visible focus indicator
2.5.5 Touch target >= 44x44 CSS pixels

Understandable

3.2.1 Predictable on focus (no unexpected changes)
3.3.1 Error identification (describe the error)
3.3.2 Labels or instructions for inputs

Robust

4.1.2 Name, role, value for all UI components

Common Issues

Insufficient color contrast
Missing form labels
No keyboard access to interactive elements
Missing alt text on meaningful images
Focus traps in modals
Missing ARIA landmarks
Auto-playing media without controls
Time limits without extension options

Testing Approach

Automated scan (catches ~30% of issues)
Keyboard-only navigation
Screen reader testing (VoiceOver, NVDA)
Color contrast verification
Zoom to 200% — does layout break?
