UX Spec

Turn product requirements into concrete flows, screens, and interactions that coding agents can implement.

Why This Exists

Bridges the gap between product requirements and implementation by defining how the product looks and behaves.

Input Requirements

This skill expects:

• PRD (from prd-generation or user-provided)
• Any existing sketches, wireframes, or references (optional)
• Design preferences or constraints (optional)

Workflow

Step 1: Ingest PRD

Extract from the PRD:

• User stories (especially Must Have)
• Features and acceptance criteria
• Target user characteristics
• Technical constraints

Step 2: Map User Flows

For each core user story, define the flow:

Questions to answer:

• Where does the user start?
• What's the happy path?
• What are the decision points?
• Where does the user end up?
• What can go wrong?

Step 3: Define Screens

For each screen in the flows:

• What's the purpose?
• What components are needed?
• What data is displayed?
• What actions are available?
• What states exist?

Step 4: Specify Interactions

For key interactions:

• What triggers the action?
• What feedback does the user get?
• What changes on screen?
• How long does it take?

Step 5: Clarify Gaps

Ask targeted questions if needed:

• "Should this be a modal or a new page?"
• "What happens if the list is empty?"
• "How does the user know it's loading?"
• "Any specific layout preference—sidebar, tabs, single page?"

Output Format

Automatically save the output todesign/06-ux-spec.md using the Write tool while presenting it to the user.

# UX Spec: [Project Name]

## Overview
[Brief summary of the product and primary user goal]

---

## Information Architecture

### Navigation Structure

[App Name] ├── [Primary Nav Item 1] │ ├── [Sub-item] │ └── [Sub-item] ├── [Primary Nav Item 2] └── [Primary Nav Item 3]

### Key User Paths
1. **[Path Name]:** [Start] → [Step] → [Step] → [End]
2. **[Path Name]:** [Start] → [Step] → [End]

---

## User Flows

### Flow 1: [Flow Name]
**Trigger:** [What initiates this flow]
**User goal:** [What they're trying to accomplish]

[Start State] ↓ [Action/Decision] ↓ [Screen/State] ──→ [Alternative path if applicable] ↓ [End State]

**Steps:**
1. User [action]
2. System [response]
3. User [action]
4. System [response]
5. User reaches [end state]

**Error paths:**
- If [condition]: [what happens]
- If [condition]: [what happens]

### Flow 2: [Flow Name]
[Same structure]

---

## Screens

### Screen: [Screen Name]
**URL/Route:** `/path`
**Purpose:** [What the user accomplishes here]
**Entry points:** [How users get here]

#### Layout

┌─────────────────────────────────┐ │ [Header/Nav] │ ├─────────────────────────────────┤ │ │ │ [Main Content Area] │ │ │ │ [Component] [Component] │ │ │ ├─────────────────────────────────┤ │ [Footer/Actions] │ └─────────────────────────────────┘

#### Components
| Component | Description | Behavior |
|-----------|-------------|----------|
| [Name] | [What it displays] | [How it behaves] |
| [Name] | [What it displays] | [How it behaves] |

#### States
| State | Appearance | Trigger |
|-------|------------|---------|
| Default | [Description] | Initial load |
| Loading | [Description] | Data fetching |
| Empty | [Description] | No data exists |
| Error | [Description] | Request failed |
| Success | [Description] | Action completed |

#### Actions
| Action | Trigger | Result |
|--------|---------|--------|
| [Action] | [Click/tap/etc.] | [What happens] |
| [Action] | [Trigger] | [Result] |

### Screen: [Screen Name]
[Same structure]

---

## Components

### Component: [Component Name]
**Used in:** [List of screens]
**Purpose:** [What it does]

#### Props/Inputs
| Prop | Type | Description |
|------|------|-------------|
| [name] | [type] | [what it controls] |

#### Variants
- **[Variant 1]:** [Description]
- **[Variant 2]:** [Description]

#### States
- Default: [Description]
- Hover: [Description]
- Active: [Description]
- Disabled: [Description]

### Component: [Component Name]
[Same structure]

---

## Interactions

### Interaction: [Name]
**Trigger:** [User action]
**Response:** [System behavior]
**Duration:** [Instant / 200ms / async]
**Feedback:** [What user sees/feels]

### Interaction: [Name]
[Same structure]

---

## Responsive Behavior
**Breakpoints:**
- Mobile: < 768px
- Tablet: 768px - 1024px
- Desktop: > 1024px

**Key adaptations:**
- [Component/layout]: [How it changes]
- [Component/layout]: [How it changes]

---

## Design Notes
[Optional — any specific visual direction, references, or constraints]

- **Style:** [Minimal / Dense / Playful / etc.]
- **Reference:** [Any inspiration or similar products]
- **Constraints:** [Accessibility, brand, etc.]

Adaptation Guidelines

Simple project (1-3 screens):

• Skip Information Architecture
• Combine Flows and Screens
• Minimal Components section
• Skip Responsive Behavior

Medium project (4-8 screens):

• Full structure as shown
• Focus on core flows, not edge cases

Complex project (10+ screens):

• Add screen-by-screen detail
• Document all component variants
• Include edge case flows
• Add Design Notes section

Writing Guidelines

• ASCII layouts are sufficient — Don't overcomplicate, just show structure
• States are critical — Loading, empty, error states prevent agent guesswork
• Be specific about triggers — "Click" vs "hover" vs "focus" matters
• Name things consistently — Use same component names across screens

Handoff

After presenting the UX spec, ask:

"Ready to generate prompts.md with /prompt-export, or want to refine any screens first?"

Note: File is automatically saved to design/06-ux-spec.md. This feeds into development prompts.
