Accessibility A11ymindrally/skillsImplement web accessibility (a11y) best practices following WCAG guidelines to create inclusive, accessible user interfaces.01Accessibility Advocatedylantarre/animation-principlesUse when designing inclusive animations, addressing vestibular disorders and motion sensitivity, or ensuring animation accessibility compliance.01Accessibility Auditaccesslint/skillsWhole site or product — a full web accessibility (a11y) audit against WCAG 2.2, following the WCAG-EM methodology. Defines scope, samples representative pages and flows, runs the automated tier (`accessibility-scan`) and the hands-on manual tier (`accessibility-inspect`), and produces one conformance report. Grades each finding by severity and evidence basis, and states per-criterion conformance as pass, fail, or undetermined (needs a human). Use it for 'audit my site for accessibility', 'is this product accessible', 'a11y audit', 'WCAG or Section 508 conformance report', or any multi-page assessment. Assesses; does not fix (use `accessibility-fix`) or diff (use `accessibility-diff`). For a single page use `accessibility-scan`; for hands-on keyboard and screen-reader checks use `accessibility-inspect`.01Accessibility Auditowl-listener/designer-skillsAudit an existing interface against WCAG, producing findings with severity ratings and remediation steps. Use when you have a design or build to assess now. Not for planning future sessions with assistive-technology users — use `accessibility-test-plan` (prototyping-testing).01Accessibility Auditwebflow/webflow-skillsRun comprehensive accessibility audit (WCAG 2.1) on Webflow pages - checks buttons, forms, links, focus states, headings, keyboard navigation, and generates detailed reports with fixes. Runs entirely headlessly against a page ID — no Designer connection required. Excludes image alt text (covered by asset-audit skill).01Accessibility Auditingspencerpauly/awesome-cursor-skillsUse Cursor's browser aria snapshots to audit a page for accessibility issues — missing labels, broken tab order, contrast, and ARIA misuse.01Accessibility Auditordavila7/claude-code-templatesWeb accessibility specialist for WCAG compliance, ARIA implementation, and inclusive design. Use when auditing websites for accessibility issues, implementing WCAG 2.1 AA/AAA standards, testing with screen readers, or ensuring ADA compliance. Expert in semantic HTML, keyboard navigation, and assistive technology compatibility.01Accessibility Complianceaj-geddes/useful-ai-prompts>08Accessibility Compliancewshobson/agentsImplement WCAG 2.2 compliant interfaces with mobile accessibility, inclusive design patterns, and assistive technology support. Use when auditing accessibility, implementing ARIA patterns, building for screen readers, or ensuring inclusive user experiences.05Accessibility Compliance Accessibility Auditsickn33/agentic-awesome-skillsYou are an accessibility expert specializing in WCAG compliance, inclusive design, and assistive technology compatibility. Conduct audits, identify barriers, and provide remediation guidance.02Accessibility Diffaccesslint/skillsRegression check — diff a live page's web accessibility (a11y) violations against a baseline. By default it compares your uncommitted changes (stash-based); pass `--branch [<name>]` to compare against a branch. Reports the new WCAG violations introduced, the ones fixed, and the count of pre-existing ones. Use it for 'did my change break accessibility', 'what a11y issues did this PR add', or as a CI gate. For a full scan of one page use `accessibility-scan`; for a whole site use `accessibility-audit`.01Accessibility Fixaccesslint/skillsRemediation only — repair web accessibility (a11y) violations against WCAG 2.2 with a baseline, edit, and verify loop. Takes a target (URL, files, directory) or a findings worklist from `accessibility-scan`/`accessibility-inspect`/`accessibility-audit`, applies mechanical fixes as given, leaves TODOs for visual or contextual judgment, and verifies by re-running the baseline check. It only fixes. To find issues use `accessibility-scan` (one page, automated), `accessibility-inspect` (one page, manual), or `accessibility-audit` (whole site, WCAG-EM); to check for regressions use `accessibility-diff`. Use it for 'fix the a11y issues in X', 'make this accessible', 'add missing alt text and labels', 'apply these accessibility fixes', 'remediate these violations'.01Accessibility Inspectaccesslint/skillsOne page, hands-on manual tier — drive a live page through the web accessibility (a11y) checks a rule engine can't decide: keyboard operation and focus order, screen-reader names, roles and states from the accessibility tree, reflow and zoom, reduced motion, form errors, and target size. Grades each finding by evidence basis (verified / confirm-with-a-human / human-required) and severity, and closes every criterion in a ledger: verified, flagged, not exercised, or N/A. Locates and assesses; does not fix (use `accessibility-fix`). Use it for keyboard testing, focus-order checks, screen-reader or a11y-tree review, reflow and zoom at 200%, or 'is this operable, not just lint-clean'. The automated tier is `accessibility-scan`; `accessibility-audit` runs both across a sampled site.02Accessibility Issuesdylantarre/animation-principlesUse when animation excludes users with vestibular disorders, cognitive disabilities, or assistive technology needs01Accessibility Reviewanthropics/knowledge-work-pluginsRun 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.01Accessibility Scanaccesslint/skillsOne page, automated tier — run the web accessibility (a11y) rule engine against a live page and locate every violation it can detect mechanically. Pass a URL, a config target name (e.g. `accesslint:accessibility-scan dev`), or nothing to use the default target from `accesslint.config.json`. Ensures a debuggable Chrome, runs the @accesslint/core engine over CDP, and returns a worklist of live-DOM WCAG 2.2 violations, each grounded to its DOM selector and source `file:line`. Locates; doesn't edit. Use it for 'is this page accessible', 'check a11y on this URL', 'find contrast and alt-text issues', or to verify a UI change. For hands-on keyboard and screen-reader checks use `accessibility-inspect`; for a whole site or product use `accessibility-audit`; to diff against uncommitted changes or a branch use `accessibility-diff`.01Accessibility Test Planowl-listener/designer-skillsPlan accessibility testing — assistive technologies, participant criteria, WCAG coverage, and session protocol. Use when scheduling testing with real AT users. Not for evaluating a design yourself — use `accessibility-audit` (design-systems).01Accessibility Testingaj-geddes/useful-ai-prompts>09Accessibility Testingpetrkindlmann/qa-skills>-03Accessible Animationiart-ai/web-animation-skillsThis skill should be used when the user asks to "respect prefers-reduced-motion", "honor reduced motion", "make my animations accessible", "fix vestibular / motion-sickness issues", "add a useReducedMotion hook", "gate GSAP / Framer Motion / Lenis for reduced motion", or "meet WCAG 2.3.3 / C39". Provides tiered (not all-or-nothing) reduced-motion patterns in CSS and JS.03Accessible Motiondylantarre/animation-principlesUse when implementing reduced motion alternatives, vestibular-safe animations, WCAG compliance, or designing for users with motion sensitivity.01Accessorysetupkitdpearson2699/swift-ios-skillsDiscover and configure Bluetooth and Wi-Fi accessories using AccessorySetupKit.
