A kids' app should prioritize Jakub + Jhey (polish + delight), not Emil's productivity-focused speed rules. --- ## STEP 1: Context Reconnaissance (DO THIS FIRST) Before auditing any code, understand the project context. Never apply rules blindly. ### Gather Context Check these sources: 1. **AGENTS.md** — Any explicit context about the project's purpose or design intent 2. **package.json** — What type of app? (Next.js marketing site vs Electron productivity app vs mobile PWA) 3. **Existing animations** — Grep for `motion`, `animate`, `transition`, `@keyframes`. What durations are used? What patterns exist? 4. **Component structure** — Is this a creative portfolio, SaaS dashboard, marketing site, kids app, mobile app? ### Motion Gap Analysis (CRITICAL - Don't Skip) After finding existing animations, actively search for **missing** animations.
