High-Agency Frontend Skill

0. ANTI-SLOP BASELINE [MANDATORY]

Before applying anything below, read references/ui-anti-slop.md and apply every rule in it. That file is the canonical anti-slop ruleset (typography, color, layout, motion, states, content, icons, code quality, accessibility). This skill adds the following stricter / additional stances on top of it:

• Serif is strictly banned on Dashboard/Software UI (anti-slop allows editorial serif; this skill forbids serif on data UI entirely).
• Aesthetic target is "Vercel-core meets Dribbble-clean": absolute neutral bases, single high-contrast accent, dial-driven variance (Section 1).
• Everything in the dial system, React/Next architecture, Framer technique sections, Creative Arsenal, and Bento paradigm below is unique to this skill and not in the anti-slop reference.

1. ACTIVE BASELINE CONFIGURATION

• DESIGN_VARIANCE: 8 (1=Perfect Symmetry, 10=Artsy Chaos)
• MOTION_INTENSITY: 6 (1=Static/No movement, 10=Cinematic/Magic Physics)
• VISUAL_DENSITY: 4 (1=Art Gallery/Airy, 10=Pilot Cockpit/Packed Data)

AI Instruction: The standard baseline for all generations is strictly set to these values (8, 6, 4). Do not ask the user to edit this file. Otherwise, ALWAYS listen to the user: adapt these values dynamically based on what they explicitly request in their chat prompts. Use these baseline (or user-overridden) values as your global variables to drive the specific logic in Sections 3 through 7.

2. DEFAULT ARCHITECTURE & CONVENTIONS

Unless the user explicitly specifies a different stack, adhere to these structural constraints to maintain consistency:

• DEPENDENCY VERIFICATION [MANDATORY]: Before importing ANY 3rd party library (e.g. framer-motion, lucide-react, zustand), you MUST check package.json. If the package is missing, you MUST output the installation command (e.g. npm install package-name) before providing the code. Never assume a library exists.
• Framework & Interactivity: React or Next.js. Default to Server Components (RSC).
  • RSC SAFETY: Global state works ONLY in Client Components. In Next.js, wrap providers in a "use client" component.
  • INTERACTIVITY ISOLATION: If Sections 4 or 7 (Motion/Liquid Glass) are active, the specific interactive UI component MUST be extracted as an isolated leaf component with 'use client' at the very top. Server Components must exclusively render static layouts.
• State Management: Use local useState/useReducer for isolated UI. Use global state strictly for deep prop-drilling avoidance.
• Styling Policy: Use Tailwind CSS (v3/v4) for 90% of styling.
  • TAILWIND VERSION LOCK: Check package.json first. Do not use v4 syntax in v3 projects.
  • T4 CONFIG GUARD: For v4, do NOT use tailwindcss plugin in postcss.config.js. Use @tailwindcss/postcss or the Vite plugin.
• ANTI-EMOJI POLICY [CRITICAL]: NEVER use emojis in code, markup, text content, or alt text. Replace symbols with high-quality icons (Radix, Phosphor) or clean SVG primitives. Emojis are BANNED.
• Responsiveness & Spacing:
  • Standardize breakpoints (sm, md, lg, xl).
  • Contain page layouts using max-w-[1400px] mx-auto or max-w-7xl.
  • Viewport Stability [CRITICAL]: NEVER use h-screen for full-height Hero sections. ALWAYS use min-h-[100dvh] to prevent catastrophic layout jumping on mobile browsers (iOS Safari).
  • Grid over Flex-Math: NEVER use complex flexbox percentage math (w-[calc(33%-1rem)]). ALWAYS use CSS Grid (grid grid-cols-1 md:grid-cols-3 gap-6) for reliable structures.
• Icons: You MUST use exactly @phosphor-icons/react or @radix-ui/react-icons as the import paths (check installed version). Standardize strokeWidth globally (e.g., exclusively use 1.5 or 2.0).
