What problem does it solve? Building visually distinctive frontend interfaces requires design judgment that a general-purpose agent often lacks. This Skill lets the main agent delegate all frontend design work to a specialized DESIGN subagent, ensuring fullstack apps, landing pages, and mockup variants get deliberate visual direction instead of generic layouts. ## Core Features & Use Cases - Subagent Delegation: Launch a DESIGN-specialized subagent via startAsyncSubagent with a rich creative brief covering product identity, vibe, pages, data types, and API hooks. - Three Task Modes: Supports fullstack react-vite apps with backend hooks, mockup sandbox prototypes, and variant exploration with distinct vibes per variant. - Brand Grounding: Extracts real brand context (colors, fonts, logos, messaging) from existing company sites using extractBranding, imageSearch, and webFetch before delegating. - Use Case: When building a CRM dashboard, you write a brief with the product identity, route list, data types, and generated API hooks, then the DESIGN subagent makes all layout, color, typography, and motion decisions autonomously. ## Quick Start Ask the agent to delegate the frontend design of your app to the DESIGN subagent with a creative brief describing the product identity and vibe.
