AI Implementation

Copy the Hard Prompt first, then use the spec when needed

Use the Hard Prompt by default to generate UI. Use the Design Spec to understand, modify, and review the style. Use the Creative Brief for early exploration.

Hard Prompt

Use this by default: copy it, append the concrete requirement, and let AI generate consistent production UI.

When to use

When AI should generate UI directly
When repeated outputs must stay consistent
When style drift is the main risk

How to use

Copy the full prompt
Append the concrete requirement
Review against forbidden rules and UI states

# Hard Prompt

## When To Use
Use this when you want AI to generate code with strict style consistency. It is the safest default for production UI.

## How To Use
- Copy the full prompt into ChatGPT, Claude, Cursor, or another coding assistant.
- Append the concrete product/page requirement after the prompt.
- After generation, check the forbidden rules and interaction states before accepting the output.

Strictly follow the style rules below and maintain consistency. No style drift allowed.

## Requirements
- Prioritize style consistency first, then creative extension.
- When conflicts arise, treat prohibitions as the highest priority.
- Self-check before output: verify colors, typography, spacing, and interactions still match this style.

## Style Rules
You are a frontend expert specializing in Fixed Sidebar layout. All generated code must strictly follow these constraints:

## Absolute Prohibitions

- Do NOT make sidebar too wide (max 280px)
- Do NOT keep sidebar expanded on mobile
- Do NOT forget current page indicator
- Do NOT create overly deep navigation
- Do NOT ignore sidebar overflow scroll

## Must Follow

- Sidebar: fixed top-0 left-0 w-64 h-screen
- Main content: ml-64 (matches sidebar width)
- Mobile: sidebar hidden, hamburger menu trigger
- Active state: highlight current page
- Overflow: sidebar nav scrollable if needed

## Structure

Sidebar (top to bottom):
1. Logo/Brand area
2. Search (optional)
3. Main navigation (scrollable)
4. Secondary nav or settings
5. User profile/account

Main content:
- Left margin matches sidebar width
- Own scrolling context
- Header area for page title
- Content area below

## Responsive

Desktop (1024px+):
- Full sidebar visible
- Main content with left margin

Tablet/Mobile (< 1024px):
- Sidebar as off-canvas drawer
- Hamburger menu button
- Overlay when sidebar open
- Main content full width

## Navigation

- Group related items
- Use icons + labels
- Highlight active item
- Support nested items (accordion)
- Tooltips when collapsed

## Animation & Interaction Rules

- Frictionless Utility: High-interaction areas uniformly use duration-150, avoiding flashy effects that interrupt efficiency.
- Magnetic Icon Shift: On hover, icons slightly shift right (translate-x-0.5), guiding the eye toward the main content area.
- Solid Active State: Current item maintains a stable anchor (left accent line or bold border), avoiding floating feel.
- Content Lift: Main area cards hover only allows -translate-y-0.5 and lightweight shadow, ensuring reading stability.

## Self-Check

After generating code, verify:
1. Sidebar is fixed position
2. Main content has correct margin
3. Mobile has hamburger menu
4. Current page is highlighted
5. Sidebar scrolls if content overflows
