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: Contains Technical Standards, Aesthetic Signatures, and Creative Protocols.
• animation_reference.md: Contains 2025 Motion Standards, Physics-based animation rules, and Micro-interactions.
• 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: 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>
