Design

⚠️ CRITICAL RULES - READ FIRST

1. CHECK EXISTING DESIGNS: Always check

   docs/reference/frontend/designs/

   first
2. READ DESIGN SYSTEM: Must read

   docs/reference/frontend/design-system.md

   before designing
3. READ CONSTRAINTS: Must read

   docs/reference/frontend/constraints.md

   for tech stack
4. SAVE TO CORRECT PATH:

   docs/reference/frontend/designs/{name}.md

Language Configuration

Before generating any content, check

aico.json

in project root for

language

field to determine the output language. If not set, default to English.

Process

1. Read design system: Load

   docs/reference/frontend/design-system.md

2. Read constraints: Load

   docs/reference/frontend/constraints.md

3. Read PRD/story: Load the source document from

   docs/reference/pm/

4. For each page/feature:
   • Define user flow (entry → actions → outcome)
   • Create ASCII layout
   • List all components with variants and props
   • Write content/copy
   • Document all interactions
   • Generate frontend prompt
5. Save output: ALWAYS write to

   docs/reference/frontend/designs/{name}.md

Design File Template

# [Name] Design Spec

> Project: [project-name]
> Created: YYYY-MM-DD
> Last Updated: YYYY-MM-DD

## User Flow

1. User enters from [entry point]
2. User sees [initial state]
3. User can [actions]
4. Success: [outcome]

## Layout (ASCII)

┌─────────────────────────────────────┐
│ Header │
├─────────────────────────────────────┤
│ Content │
└─────────────────────────────────────┘

## Sections

### 1. [Section Name]

- **Purpose**: What this section achieves
- **Components**: List of UI components used
- **Content**: Actual text/copy
- **Design notes**: Specific styling details

## Component List

| Component | Variants           | Props          | Notes        |
| --------- | ------------------ | -------------- | ------------ |
| Button    | primary, secondary | size, disabled | Use for CTAs |

## Responsive

- **Desktop**: [layout notes]
- **Tablet**: [layout notes]
- **Mobile**: [layout notes]

## Interactions

| Trigger   | Action      | Feedback                     |
| --------- | ----------- | ---------------------------- |
| Click CTA | Submit form | Show loading → success toast |

---

## Frontend Prompt

<context>
You are implementing [page/component name] for [project].
</context>

<constraints>
Read and follow:
- Design system: docs/reference/frontend/design-system.md
- Frontend constraints: docs/reference/frontend/constraints.md
</constraints>

<requirements>
1. Follow the design system tokens exactly
2. Implement all sections as specified
3. Handle all responsive breakpoints
4. Implement all interactions listed
</requirements>

Key Rules

• ALWAYS define user flow with entry point and success state
• MUST list specific props and variants for each component
• ALWAYS document all triggers and feedback for interactions
• Reference design system, don't duplicate it

Common Mistakes

• ❌ Skip user flow → ✅ Always define entry point and success state
• ❌ Vague component specs → ✅ List specific props and variants
• ❌ Forget interactions → ✅ Document all triggers and feedback
• ❌ Duplicate design system → ✅ Reference it, don't copy
