Invoke when developing uni-app pages, using uView components (u-button, u-input, u-form, etc.), or needing UI elements like forms, buttons, modals, toasts, navigation.0131UX Auditjezweb/claude-skillsWalk through a live web app AS a real user to find usability + behavioural bugs that static reviews miss. REQUIRES proof of interaction (typing, clicking, sending, observing) before any verdict — a sweep that didn't interact terminates with verdict 'Incomplete'. Walks threads, exercises every element, runs the multi-pane stress matrix, visual polish sweep, component perfection checklist, automated a11y (axe-core), pragmatic performance budget (LCP/CLS/INP), scenario battery (11 scenarios), and stress recipes including the real-flavour data battery. Hard gates: console errors/warnings = 0, network 5xx = 0, layout collapse = 0, axe Critical/Serious = 0, perf budget green. Audit-the-audit meta-check rejects rushed reports. Each finding has reproduction steps, evidence path, and suspected code location. Trigger with 'ux audit', 'walkthrough', 'qa sweep', 'audit the app', 'dogfood this', 'check all pages', 'find what's broken', 'stress the UI'.023UX Audit Rethinkmastepanoski/claude-skillsComprehensive UX audit using IxDF's 7 factors, 5 usability characteristics, and 5 interaction dimensions.

Produces an opinionated comparison document with recommendations for a new build. No browser needed — pure markdown analysis. Trigger with 'compare UX patterns', 'how do top apps handle X', 'ux comparison', 'pattern comparison across reference apps'.02UX Copyanthropics/knowledge-work-pluginsWrite or review UX copy — microcopy, error messages, empty states, CTAs. Trigger with "write copy for", "what should this button say?", "review this error message", or when naming a CTA, wording a confirmation dialog, filling an empty state, or writing onboarding text.01UX Designmindrally/skillsUX design principles for creating intuitive, accessible, and user-centered digital experiences01UX Designeraj-geddes/claude-code-bmad-skillsDesigns user experiences, creates wireframes, defines user flows, ensures accessibility. Trigger keywords - UX design, wireframe, user flow, accessibility, WCAG, mobile-first, responsive, UI design, user journey, interface design, user experience, design system, component design, interaction design010UX Designerszilu/ux-designer-skillUX/UI design principles for building and critiquing interfaces.

Produces a reusable pattern library that other audits can compare against. The inverse of ux-audit — asks 'what is the bar?' rather than 'does this match the bar?'. Trigger with 'learn from X', 'extract patterns from X', 'study X's UX', 'reverse engineer the UX of X', 'build a pattern library from X'.03UX Frictiondylantarre/animation-principlesUse when animation causes user confusion, delays task completion, or creates frustration01UX Heuristicswondelai/skillsEvaluate and improve interface usability using heuristic analysis. Use when the user mentions "usability audit", "users are confused", "form usability", "navigation problems", "Nielsen heuristics", "cognitive walkthrough", or "is this easy to use". Also trigger when reviewing a design for usability issues, improving form-completion rates, or evaluating information architecture and navigation. Covers Krug''s laws, Nielsen''s 10 heuristics, severity ratings, dark-pattern recognition, and accessibility. For visual design fixes, see refactoring-ui. For conversion-focused audits, see cro-methodology.08UX Principlesmanutej/luxor-claude-marketplaceUser research, usability heuristics, user psychology, accessibility, inclusive design, user testing, and UX metrics03UX Researcherdylantarre/animation-principlesUse when evaluating animation usability, conducting motion studies, or when researching how animation affects user perception and task completion.01UX Researcher Designerdavila7/claude-code-templatesUX research and design toolkit for Senior UX Designer/Researcher including data-driven persona generation, journey mapping, usability testing frameworks, and research synthesis. Use for user research, persona creation, journey mapping, and design validation.02UX Writingcontent-designer/ux-writing-skillCreate user-centered, accessible interface copy (microcopy) for digital products including buttons, labels, error messages, notifications, forms, onboarding, empty states, success messages, and help text. Use when writing or editing any text that appears in apps, websites, or software interfaces, designing conversational flows, establishing voice and tone guidelines, auditing product content for consistency and usability, reviewing UI strings, or improving existing interface copy. Applies UX writing best practices based on four quality standards — purposeful, concise, conversational, and clear. Includes accessibility guidelines, research-backed benchmarks (sentence length, comprehension rates, reading levels), expanded error patterns, tone adaptation frameworks, and comprehensive reference materials.025UX Writingowl-listener/designer-skillsWrite interface copy — microcopy, error messages, empty states, and CTAs. Use when the words are the deliverable. For content structure and ownership, use `content-strategy` (ux-strategy).01Uzi Skill Stock Analyzerreason-machines/trending-skillsAI-powered deep stock analysis engine for A-share/HK/US markets with 51 investor personas, 22 data dimensions, 180 quantitative rules, and 17 institutional methods01V3 CLI Modernizationruvnet/rufloCLI modernization and hooks system enhancement for claude-flow v3.
