# {{Project Name}} UI/UX Specification

[[LLM: Review provided documents including Project Brief, PRD, and any user research to gather context. Focus on understanding user needs, pain points, and desired outcomes before beginning the specification.]]

## Introduction

[[LLM: Establish the document's purpose and scope. Keep the content below but ensure project name is properly substituted.]]

This document defines the user experience goals, information architecture, user flows, and visual design specifications for {{Project Name}}'s user interface. It serves as the foundation for visual design and frontend development, ensuring a cohesive and user-centered experience.

### Overall UX Goals & Principles

[[LLM: Work with the user to establish and document the following. If not already defined, facilitate a discussion to determine:

1. Target User Personas - elicit details or confirm existing ones from PRD
2. Key Usability Goals - understand what success looks like for users
3. Core Design Principles - establish 3-5 guiding principles

After presenting this section, apply `tasks#advanced-elicitation` protocol]]

### Target User Personas

{{persona_descriptions}}

@{example: personas}

- **Power User:** Technical professionals who need advanced features and efficiency
- **Casual User:** Occasional users who prioritize ease of use and clear guidance
- **Administrator:** System managers who need control and oversight capabilities
  @{/example}

### Usability Goals

{{usability_goals}}

@{example: usability_goals}

- Ease of learning: New users can complete core tasks within 5 minutes
- Efficiency of use: Power users can complete frequent tasks with minimal clicks
- Error prevention: Clear validation and confirmation for destructive actions
- Memorability: Infrequent users can return without relearning
  @{/example}

### Design Principles

{{design_principles}}

@{example: design_principles}

1. **Clarity over cleverness** - Prioritize clear communication over aesthetic innovation
2. **Progressive disclosure** - Show only what's needed, when it's needed
3. **Consistent patterns** - Use familiar UI patterns throughout the application
4. **Immediate feedback** - Every action should have a clear, immediate response
5. **Accessible by default** - Design for all users from the start
   @{/example}

### Change Log

[[LLM: Track document versions and changes]]

| Date | Version | Description | Author |
| :--- | :------ | :---------- | :----- |

## Information Architecture (IA)

[[LLM: Collaborate with the user to create a comprehensive information architecture:

1. Build a Site Map or Screen Inventory showing all major areas
2. Define the Navigation Structure (primary, secondary, breadcrumbs)
3. Use Mermaid diagrams for visual representation
4. Consider user mental models and expected groupings

After presenting this section, apply `tasks#advanced-elicitation` protocol]]

### Site Map / Screen Inventory

```mermaid
{{sitemap_diagram}}
```

@{example: sitemap}

```mermaid
graph TD
    A[Homepage] --> B[Dashboard]
    A --> C[Products]
    A --> D[Account]
    B --> B1[Analytics]
    B --> B2[Recent Activity]
    C --> C1[Browse]
    C --> C2[Search]
    C --> C3[Product Details]
    D --> D1[Profile]
    D --> D2[Settings]
    D --> D3[Billing]
```

@{/example}

### Navigation Structure

**Primary Navigation:** {{primary_nav_description}}

**Secondary Navigation:** {{secondary_nav_description}}

**Breadcrumb Strategy:** {{breadcrumb_strategy}}

## User Flows

[[LLM: For each critical user task identified in the PRD:

1. Define the user's goal clearly
2. Map out all steps including decision points
3. Consider edge cases and error states
4. Use Mermaid flow diagrams for clarity
5. Link to external tools (Figma/Miro) if detailed flows exist there

Create subsections for each major flow. After presenting all flows, apply `tasks#advanced-elicitation` protocol]]

<<REPEAT: user_flow>>

### {{flow_name}}

**User Goal:** {{flow_goal}}

**Notes:** {{flow_notes}}
<</REPEAT>>

@{example: user_flow}

### User Registration

**User Goal:** Create a new account to access the platform

**Entry Points:** Homepage CTA, Login page link, Marketing landing pages

**Success Criteria:** User successfully creates account and reaches dashboard

#### Flow Diagram

```mermaid
graph TD
    Start[Landing Page] --> Click[Click Sign Up]
    Click --> Form[Registration Form]
    Form --> Fill[Fill Required Fields]
    Fill --> Submit[Submit Form]
    Submit --> Validate{Valid?}
    Validate -->|No| Error[Show Errors]
    Error --> Form
    Validate -->|Yes| Verify[Email Verification]
    Verify --> Complete[Account Created]
    Complete --> Dashboard[Redirect to Dashboard]
```

**Edge Cases & Error Handling:**

- Duplicate email: Show inline error with password recovery option
- Weak password: Real-time feedback on password strength
- Network error: Preserve form data and show retry option
  @{/example}
