Built on real design work.
Each skill encodes the checks we actually run on client work, shaped by hundreds of design reviews and shipped projects.
Free and open source.
MIT-licensed, zero network calls, no telemetry. Drop into any project. Fork, extend, or pull request to your heart's content.
Works where you work.
Claude Code, Cursor, Windsurf, or plain CLI. Each skill ships as a plugin, an npm package, and a clone-able repo.
Severity-tiered output
Blockers gate CI. Advisories nudge. No flat lists, no false-positive fatigue.
Fix-ready, not just report
Each violation comes with a concrete fix suggestion Claude can apply via the Edit tool, not just a complaint.
Configurable, not opinionated
Ignore rules, override severities, scope to changed files. Each skill respects a project-level config.
Accessibility
Accessibility Pass
Static auditor that scans JSX, HTML, Vue, and Svelte files for accessibility violations. Reports blockers, serious, and advisory issues with concrete fix suggestions and exact WCAG references.
Internationalization
Internationalization Audit
Finds hardcoded user-facing strings, missing locale keys, broken pluralization, and components that break under right-to-left or text-expansion locales like German.
UX
UX Heuristics Review
Walks a flow against a structured rubric of usability heuristics. Flags missing feedback, recovery, and consistency violations with screenshots and specific recommendations.
Content
Microcopy Pass
Reviews UI copy for voice consistency, sentence vs title case, and unclear error messages. Suggests rewrites that match a configurable tone of voice.
Design System
Design Token Compliance
Detects raw hex colors and off-grid spacing in code that should be using design tokens.
