Extract and consolidate reusable components, design tokens, and patterns into your design system. Identifies opportunities for systematic reuse and enriches your component library. Use when the user asks to create components, refactor repeated UI patterns, build a design system, or extract tokens.

Strip designs to their essence by removing unnecessary complexity. Great design is simple, powerful, and clean. Use when the user asks to simplify, declutter, reduce noise, remove elements, or make a UI cleaner and more focused.

Add moments of joy, personality, and unexpected touches that make interfaces memorable and enjoyable to use. Elevates functional to delightful. Use when the user asks to add polish, personality, animations, micro-interactions, delight, or make an interface feel fun or memorable.

Evaluate design from a UX perspective, assessing visual hierarchy, information architecture, emotional resonance, cognitive load, and overall quality with quantitative scoring, persona-based testing, and actionable feedback. Use when the user asks to review, critique, evaluate, or give feedback on a design or component.

Add strategic color to features that are too monochromatic or lack visual interest, making interfaces more engaging and expressive. Use when the user mentions the design looking gray, dull, lacking warmth, needing more color, or wanting a more vibrant or expressive palette.

Improve unclear UX copy, error messages, microcopy, labels, and instructions to make interfaces easier to understand. Use when the user mentions confusing text, unclear labels, bad error messages, hard-to-follow instructions, or wanting better UX writing.

Amplify safe or boring designs to make them more visually interesting and stimulating. Increases impact while maintaining usability. Use when the user says the design looks bland, generic, too safe, lacks personality, or wants more visual impact and character.

Run technical quality checks across accessibility, performance, theming, responsive design, and anti-patterns. Generates a scored report with P0-P3 severity ratings and actionable plan. Use when the user wants an accessibility check, performance audit, or technical quality review.

Improve layout, spacing, and visual rhythm. Fixes monotonous grids, inconsistent spacing, and weak visual hierarchy. Use when the user mentions layout feeling off, spacing issues, visual hierarchy, crowded UI, alignment problems, or wanting better composition.

Review a feature and enhance it with purposeful animations, micro-interactions, and motion effects that improve usability and delight. Use when the user mentions adding animation, transitions, micro-interactions, motion design, hover effects, or making the UI feel more alive.

Adapt designs to work across different screen sizes, devices, contexts, or platforms. Implements breakpoints, fluid layouts, and touch targets. Use when the user mentions responsive design, mobile layouts, breakpoints, viewport adaptation, or cross-device compatibility.

Run impeccable design quality commands on frontend code — audit, critique, polish, animate, normalize, and more. Built on top of the frontend-design skill with 20 steering commands and 10 domain-specific reference files. Use when doing a design QA pass, reviewing UI quality, or refining a frontend component before shipping.

Create HTML-based video compositions, animated title cards, social overlays, captioned talking-head videos, audio-reactive visuals, and shader transitions using HyperFrames. HTML is the source of truth for video. Use when the user wants a rendered MP4/WebM from an HTML composition, wants to animate text/logos/charts over media, needs captions synced to audio, wants TTS narration, or wants to convert a website into a video.

Use when creating animation-rich HTML presentations or convert PPT to web.

Create distinctive, production-grade frontend interfaces with high design quality. Generates creative, polished code that avoids generic AI aesthetics. Use when the user asks to build web components, pages, artifacts, posters, or applications, or when any design skill requires project context.

Use when creating hand-drawn style Excalidraw diagrams via the Excalidraw MCP at https://mcp.excalidraw.com/mcp. Use for flow diagrams, architecture diagrams, slide visuals, and any time a sketchy/hand-drawn diagram is needed as a PNG file.

Run a product design review on a feature or site. Answers 13 design questions, runs Nielsen Norman heuristic evaluation, builds before/after visual fixes, and deploys a shareable report to Surge. Use when asked to review a design, audit UX, do a design review, or analyze a product's user experience.

Complement to frontend-design — embodies Anthropic's design-surface system prompt (the "expert designer" persona that produces HTML artifacts, decks, prototypes, and animations in a filesystem-based project). Use when the user wants to enter "design mode" and operate as a design-artifact generator with the full Anthropic design workflow (asking questions first, exploring design systems, Tweaks, speaker notes, starter components, verifier agent), or when frontend-design has set aesthetic direction and the next step is producing the artifact. Trigger phrases: "design mode", "design artifact", "make a deck", "hi-fi prototype", "Anthropic design mode", "Claude design sys prompt", "design like claude.ai/design".

Use when creating, editing, or validating DESIGN.md files, design tokens, DTCG token specs, Tailwind theme exports, design system documentation, WCAG contrast checks, or Google Stitch-compatible design specs.

Design one-off HTML artifacts (landing, deck, prototype).

Build a complete brand identity from scratch or refresh an existing one — for solopreneurs, apps, and consumer products. Covers brand purpose, values, personality, voice and tone, visual identity system (colors, typography, logo direction, imagery style), and brand guidelines. Includes a Claude/Anthropic case study showing what world-class brand identity looks like in practice — counter-positioning, palette strategy, naming, and consistency. Use when creating a new brand, rebranding, auditing visual identity, or making brand decisions consistent. Trigger on "create my brand", "brand identity", "brand guidelines", "define my brand voice", "brand personality", "what should my brand look like", "brand strategy", "rebrand", "brand tone", "what makes a strong brand", "brand case study".

Post-merge deploy verification. Waits for deploy, benchmarks production, monitors for regressions. Use after merging a PR to confirm the deploy is healthy.

Use when encountering any bug, test failure, or unexpected behavior. 4-phase root cause investigation — NO fixes without understanding the problem first.

Review changed code for reuse, quality, and efficiency, then fix any issues found. TRIGGER when user says "simplify", "clean up code", "review my changes", "code review and fix", or "/simplify".
