What this skill does
<domain_overview> # Frontend Design System > **Philosophy:** Minimize cognitive load and make interactions intuitive. Every design decision should respect human psychology, behavioral patterns, and cognitive limitations. The designer bears complexity so the user experiences simplicity. > **Core Principle:** Good design is invisible - users should accomplish their goals without noticing the design itself. Design should feel effortless and natural, aligning with how humans naturally think and behave. ## ⚠️ Core Protocols & Standards **ANTI-AI AESTHETIC MANDATE (CRITICAL):** Never use generic aesthetics that give the impression of being AI-generated. This includes overused font families (Inter, Roboto, Arial, system fonts), cliché color schemes (especially purple gradients on white backgrounds), predictable layouts, and repetitive component patterns. **ABSOLUTELY FORBIDDEN:** The "Cyberpunk" aesthetic is strictly prohibited. Do NOT use neon glows, matrix rain, glitch effects, or "high-tech" dark modes unless explicitly requested for a specific context. This cliché is the hallmark of lazy AI generation. Specifically avoid template-driven designs that lack context-specific character. This skill aims to create distinctive, original, and production-level frontends. Realize functional, high-fidelity code by paying extraordinary attention to aesthetic details and creative decisions. **CRITICAL PROTOCOL:** The detailed rules are stored in separate reference files. You **MUST** use the `Read` tool to load these files into your context **BEFORE** starting any design work. Do not assume you know the contents. - **[frontend_reference.md](frontend_reference.md)**: Contains Technical Standards, Aesthetic Signatures, and Creative Protocols. - **[animation_reference.md](animation_reference.md)**: Contains 2025 Motion Standards, Physics-based animation rules, and Micro-interactions. - **[css_art_reference.md](css_art_reference.md)**: **FOR VISUAL OBJECTS.** Use this when asked to "draw" or "create" complex items (Swords, Logos, Icons) using code. Defines Geometric Composition & LCH Materials. - **[security-protocols.md](security-protocols.md)**: Contains critical Frontend Security rules. ## 🎬 Core Animation Principles > **Motion Mandate:** Animation must be **Physics-Based** (Springs), **Continuous** (No Teleportation), and **Meaningful** (Storytelling). - **Continuity:** State changes must morph, not cut (View Transitions). - **Weight:** Objects must feel like they have mass (Use Spring Animations). - **Focus:** Animation guides attention; it does not distract. - **Narrative:** Every motion tells a story about where an element came from and where it is going. *(See `animation_reference.md` for the full 12-Principle Framework)* ## 🔗 Related & Required Skills When executing Frontend tasks, you **MUST** integrate these complementary skills to ensure architectural integrity: | Skill | Purpose in Frontend Context | |-------|-----------------------------| | **`brainstorming`** | **MANDATORY PRE-REQUISITE.** Before ANY design work, use this to interrogate the user's vague instructions and crystallize the "Screenplay/Narrative" defined in `frontend_reference.md`. | | **`clean-code`** | **MANDATORY.** Ensures component modularity, cleaner hooks/state logic, and security compliance. Prevents "spaghetti UI code". | | **`tdd-mastery`** | **MANDATORY.** "Iron Law" applies to components too. Use for visual regression tests and logic verification before coding UI. | | **`optimization-mastery`** | Use for Performance Audits (Lighthouse, Core Web Vitals), reducing bundle size, and optimizing re-renders. | | **`backend-design`** | Consult this when defining API data shapes, error handling states, and ensuring type safety across the network boundary. | | **`planning-mastery`** | Use this to break down complex UI implementations into "Atomic" deliverables (Atoms -> Molecules -> Organisms). | ## 🛠️ Automation Scripts Use the following script to audit your implementation: - **`scripts/js/ux-audit.js`**: Run this to perform a heuristic analysis of the UI for consistency, accessibility (contrast/spacing), and compliance with the design tokens. - *Usage:* `node scripts/js/ux-audit.js` </domain_overview>

contribute
IncludedLocal-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".
architectural-analysis
IncludedUser-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).
mcp
IncludedModel Context Protocol (MCP) server development and tool management. Languages: Python, TypeScript. Capabilities: build MCP servers, integrate external APIs, discover/execute MCP tools, manage multi-server configs, design agent-centric tools. Actions: create, build, integrate, discover, execute, configure MCP servers/tools. Keywords: MCP, Model Context Protocol, MCP server, MCP tool, stdio transport, SSE transport, tool discovery, resource provider, prompt template, external API integration, Gemini CLI MCP, Claude MCP, agent tools, tool execution, server config. Use when: building MCP servers, integrating external APIs as MCP tools, discovering available MCP tools, executing MCP capabilities, configuring multi-server setups, designing tools for AI agents.
react-native-skia
IncludedDesign, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.
plaid
IncludedProduct Led AI Development — guides founders from idea to launched product. Six capabilities: Idea (discover a product idea), Validate (pressure-test the idea against fatal flaws, problem reality, competition, and 2-week MVP feasibility), Plan (vision intake + document generation), Design (translate image references into a design.md spec), Launch (go-to-market strategy), and Build (roadmap execution). Use when someone says "PLAID", "plaid idea", "help me find an idea", "product idea", "idea from my business", "idea from my expertise", "plaid validate", "validate my idea", "pressure-test", "is this idea good", "find fatal flaws", "validate the problem", "plan a product", "define my vision", "generate a PRD", "product strategy", "plaid design", "design from image", "translate image to design", "create design.md", "extract design tokens", "plaid launch", "go-to-market", "launch plan", "GTM strategy", "launch playbook", "plaid build", "build the app", "start building", or "execute the roadmap".
nextjs-framer-motion-animations
IncludedAdds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
