Favor CSS transforms (`translate`, `scale`, `opacity`) over properties that trigger layout changes (e.g., `width`, `height`, `margin`). +- **Touch Feedback:** Animations should respond instantly to touch, providing immediate feedback. +- **Gesture-based:** Animations often tied to gestures (swipe, pinch). Use libraries that handle touch events well. +- **Screen Transitions:** Native-like slide or push transitions are common. + +### Desktop Considerations +- **Hover States:** More emphasis on hover-triggered animations. +- **Larger Screen Real Estate:** Can use more complex, subtle animations without feeling cluttered. +- **Micro-interactions:** Subtle animations on elements like tooltips, dropdowns, and menus enhance the experience. + +## Tool Recommendations + +### Animation Libraries +- **Framer Motion:** A production-ready React animation library. Excellent for complex, declarative animations and gestures. +- **AutoAnimate:** Zero-config, drop-in animation utility that adds smooth transitions to your app. +- **GSAP (GreenSock Animation Platform):** A professional-grade animation library for high-performance animations. +- **Lottie:** For rendering After Effects animations in real-time. Ideal for complex illustrations and loading animations. + +### CSS +- **CSS Transitions:** For simple state changes (e.g., hover, focus). +- **CSS Keyframe Animations:** For more complex, multi-step animations. +- **Tailwind CSS:** The `transition` and `animate` utilities are great for quick, common animations. + +## Handoff to Developers + +### Specification Details +- **Property:** The CSS property to be animated (e.g., `opacity`, `transform`). +- **Duration:** How long the animation takes (in ms). +- **Easing:** The timing function (e.g., `ease-in-out`, `cubic-bezier(0.4, 0, 0.6, 1)`). +- **Delay:** Any delay before the animation starts. +- **Trigger:** The user action or event that starts the animation. + +### Example Specification +``` +Component: Modal Dialog +- Entrance: + - Overlay: Fade in (opacity 0 to 1), 200ms, ease-out. + - Dialog Box: Scale up (scale 0.95 to 1) and fade in (opacity 0 to 1), 250ms, ease-out, 50ms delay. +- Exit: + - Overlay: Fade out, 150ms, ease-in. + - Dialog Box: Scale down (scale 1 to 0.95) and fade out, 150ms, ease-in. +``` + +## Best Practices +- **Purposeful:** Every animation should have a reason to exist. +- **Subtle:** Avoid long, distracting animations. Durations of 200-400ms are often best. +- **Accessible:** Respect `prefers-reduced-motion` media query. +- **Consistent:** Use consistent easing and duration for similar types of interactions. + +## Pitfalls to Avoid +- **Layout Thrashing:** Animating properties like `width`, `height`, `top`, `left`. +- **Over-animation:** Too much movement can be distracting and overwhelming. +- **Ignoring Mobile:** Animations that are smooth on desktop may be janky on mobile. +- **No Reduced Motion Support:** Failing to provide an alternative for users who are sensitive to motion. + +## Output Format +- Interactive prototypes (Figma, Framer). +- Animation specifications with duration, easing, and properties. +- Code snippets or library-specific examples (e.g., Framer Motion variants). +- Lottie JSON files for complex vector animations. + +## Communication Style +Clear and concise, using visual examples and prototypes whenever possible.

The design is synthesized from the collective expertise of the UI/UX, animation, and engineering agents. + +## 1. Guiding Principles + +- **Mobile-First, Desktop-Adapted:** While adapting a desktop app, we will prioritize a true mobile-native feel. Components and layouts are designed for small screens first and then adapted for larger ones. (Derived from `ux-researcher`, `ui-designer`). +- **Performant & Fluid:** Animations and interactions will be lightweight, purposeful, and optimized for mobile CPUs to ensure a smooth 60fps experience. We will favor CSS transforms and opacity changes. (Derived from `animations-specialist`). +- **Consistent & On-Brand:** The mobile design will adhere to the existing design system, including colors, typography, and spacing, to maintain a consistent brand identity. (Derived from `ui-designer`). +- **Action-Oriented:** The mobile experience will focus on the most common, on-the-go user actions: checking status, viewing feedback, and quick edits. (Derived from `ux-researcher`). +- **Component-Driven:** We will reuse and adapt existing React components wherever possible, using responsive props and styles to avoid duplicating code. (Derived from `frontend-developer`). + +## 2. Global Navigation + +The primary desktop sidebar navigation will be replaced with a top navigation bar and a slide-out menu on mobile. + +### 2.1. Top Navigation Bar + +The top bar provides access to the main navigation, user profile, and primary actions. + +**ASCII Wireframe:** +``` +┌──────────────────────────────────────────────────┐ +│ [☰] Resume Optimizer [🔔] [👤] │ +└──────────────────────────────────────────────────┘ +``` + +- **`[☰]` (Hamburger Menu):** Toggles the slide-out navigation menu. +- **`Resume Optimizer` (Logo/Title):** Centered or to the right of the menu icon. +- **`[🔔]` (Notifications):** Opens a dropdown or a new screen with recent notifications. +- **`[👤]` (User Avatar):** Opens a dropdown with links to the Profile/Settings and Logout. + +### 2.2. Slide-Out Navigation Menu + +Activated by the hamburger icon, this menu slides in from the left, overlaying the content. + +**Animation:** +- **Menu Container:** Slides in from the left (`translateX(0)` from `translateX(-100%)`). Duration: 300ms, Easing: `ease-out`. +- **Overlay:** Fades in (`opacity(1)` from `opacity(0)`) behind the menu to dim the main content. + +**ASCII Wireframe (Menu Open):** +``` +┌──────────────────┬───────────────────────────────┐ +│ Logo │ │ +├──────────────────┤ [✕] Close │ +│ Dashboard │ │ +│ My Resumes │ │ +│ Analytics │ Main Content (Dimmed) │ +│ Integrations │ │ +├──────────────────┤ │ +│ Settings │ │ +│ Logout │ │ +└──────────────────┴───────────────────────────────┘ +``` + +## 3. Screen Designs + +### 3.1. Dashboard + +The mobile dashboard provides an at-a-glance overview of the user's status and recent activity. + +**Layout:** A single-column vertical feed. + +**ASCII Wireframe:** +``` +┌──────────────────────────────────────────┐ +│ Dashboard │ +├──────────────────────────────────────────┤ +│ │ +│ ┌────────────────────────────────────┐ │ +│ │ Resume Score: 88% (▲ 5%) │ │ +│ └────────────────────────────────────┘ │ +│ │ +│ Recent Activity │ +│ ┌────────────────────────────────────┐ │ +│ │ ● New feedback on "Senior SWE" │ │ +│ │ 2 hours ago │ │ +│ └────────────────────────────────────┘ │ +│ ┌────────────────────────────────────┐ │ +│ │ ✓ "Data Scientist" resume analyzed │ │ +│ │ 1 day ago │ │ +│ └────────────────────────────────────┘ │ +│ │ +│ [+] │ +└──────────────────────────────────────────┘ +``` + +**Components:** +- **Stat Card (`Resume Score`):** A prominent card at the top displaying the primary KPI. It should be touch-friendly, perhaps flipping to reveal more details. +- **Activity List:** A list of recent events, rendered as individual cards. Each card is a touch target leading to the relevant detail view. +- **Floating Action Button (FAB) `[+]`:** A sticky button for the primary action, like "Analyze New Resume". This provides immediate access to the app's core function. + +**Animations:** +- **Initial Load:** Use skeleton loaders for the stat card and activity list. +- **List Entrance:** The activity cards will animate in with a staggered fade-in and slide-up effect. (From `animations-specialist`: `staggerChildren`). +- **FAB:** The FAB will have a subtle scale-up on press for touch feedback. + +### 3.2. Profile & Settings Section + +This section will be a single, scrollable screen, using list views for clarity and ease of use. + +**Layout:** Grouped list items. + +**ASCII Wireframe:** +``` +┌──────────────────────────────────────────┐ +│ Settings │ +├──────────────────────────────────────────┤ +│ │ +│ ┌────────────────────────────────────┐ │ +│ │ [👤] John Doe │ │ +│ │ john.doe@email.com │ │ +│ └────────────────────────────────────┘ │ +│ │ +│ ACCOUNT │ +│ ┌────────────────────────────────────┐ │ +│ │ Edit Profile > │ │ +│ ├────────────────────────────────────┤ │ +│ │ Change Password > │ │ +│ └────────────────────────────────────┘ │ +│ │ +│ NOTIFICATIONS │ +│ ┌────────────────────────────────────┐ │ +│ │ Push Notifications [toggle] │ +│ ├────────────────────────────────────┤ │ +│ │ Email Notifications [toggle] │ +│ └────────────────────────────────────┘ │ +│ │ +│ [ Logout Button ] │ +│ │ +└──────────────────────────────────────────┘ +``` + +**Components:** +- **User Header:** A non-interactive header displaying the user's avatar, name, and email. +- **Setting Groups:** Use section headers (`ACCOUNT`, `NOTIFICATIONS`) to group related settings. +- **List Items:** Each setting is a list item. + - **Navigation Items (`>`):** Tapping navigates to a new screen (e.g., "Edit Profile"). + - **Toggle Items (`[toggle]`):** For boolean settings like enabling/disabling notifications. + +**Animations:** +- **Screen Transition:** When navigating to a sub-page (e.g., "Edit Profile"), the new screen will slide in from the right, pushing the current screen to the left. This is a standard native mobile pattern. + +## 4. Implementation Details (for Developers) + +- **Responsive Logic:** + - Use Tailwind CSS responsive prefixes (`sm:`, `md:`, `lg:`). + - The main layout component will use `flex-col` on mobile and `md:flex-row` for desktop. + - The sidebar will be hidden by default (`hidden`) and shown on larger screens (`md:block`). The hamburger menu will be visible only on mobile (`md:hidden`). + - Example: `
Mobile Nav
` + +- **Component Adaptation:** + - **Tables:** Data tables on desktop should transform into a list of cards on mobile. Each row becomes a card. + - **Forms:** Ensure all forms are single-column on mobile for usability. + +- **Data Fetching:** + - Continue using `TanStack Query`. No changes are needed, but ensure skeleton loading states are implemented for a better mobile UX, as network latency can be higher. + +- **Animation Implementation:** + - Use `Framer Motion` for complex animations like the staggered list and slide-out menu. It provides excellent gesture and animation support. + - For simple transitions like button feedback and color changes, use Tailwind's built-in transition utilities. + +## 5.
