# Accessibility Assessment Report
**Generated**: [timestamp]
**Project**: [name]
**Target WCAG Level**: [A/AA/AAA]

## Executive Summary
[Overview of accessibility requirements and key findings]

## WCAG Compliance Assessment

### Target Level: [AA]
| Principle | Guidelines | Status |
|-----------|------------|--------|
| Perceivable | 1.1-1.4 | [status] |
| Operable | 2.1-2.5 | [status] |
| Understandable | 3.1-3.3 | [status] |

## Component Accessibility Specifications

### Component: [Name]
**ARIA Role**: [role]
**Keyboard Interaction**:
| Key | Action |
|-----|--------|
| Tab | Move focus |
| Enter/Space | Activate |
| Escape | Close/Cancel |
| Arrow keys | Navigate |

**Required Attributes**:
\`\`\`html
<div role="[role]"
     aria-label="[label]"
     aria-describedby="[id]"
     tabindex="0">
</div>
\`\`\`

**Screen Reader Announcement**: [what should be announced]

[Repeat for each interactive component]

## Keyboard Navigation Design

### Tab Order
| Order | Element | Notes |
|-------|---------|-------|
| 1 | Skip to main link | Hidden until focused |
| 2 | Logo/Home link | |
| 3 | Main navigation | |
| [n] | [element] | [notes] |

### Focus Management

|------------|-------|---------|----------|
| Text on background | [ratio] | Pass/Fail | Pass/Fail |

### Non-Color Indicators
| Information | Color | Additional Indicator |
|-------------|-------|---------------------|
| Error | Red | Icon + text |

| Required | * | aria-required="true" |

## Screen Reader Support

### Landmark Structure
\`\`\`html
<header role="banner">

Build Mode Advisory

During Build Mode, this specialist's recommendations are applied by the Frontend Specialist:

The Testing Specialist should also implement accessibility tests based on these requirements.

Working Guidelines

1. Start Early: Build accessibility in, don't retrofit
2. Test with Users: Involve people with disabilities when possible
3. Use Semantic HTML: It's accessible by default
4. Progressive Enhancement: Core functionality without JS
5. Document Patterns: Create an accessibility pattern library

Prerequisites

Before starting, review outputs from:

• Frontend Specialist: Component architecture
• API Designer: Error response formats (for accessible errors)
• Planner: User requirements and compliance needs
