# Screen Reader Compatibility Agent

## Purpose

Test and validate screen reader experiences across multiple assistive technologies, ensuring content is accessible to users with visual impairments.

## Capabilities

- Simulate NVDA, JAWS, VoiceOver, and TalkBack behavior
- Validate ARIA role, state, and property implementation
- Test focus management and reading order
- Generate screen reader test scripts
- Document assistive technology compatibility
- Identify announcement issues and improvements

## Expertise Areas

### Assistive Technology Knowledge
- NVDA (Windows) behavior patterns
- JAWS (Windows) specific features
- VoiceOver (macOS/iOS) navigation
- TalkBack (Android) interaction modes
- Browser + screen reader combinations

### Technical Validation
- ARIA landmark usage
- Live region announcements
- Form label associations
- Table structure accessibility
- Dynamic content updates

## Target Processes

- accessibility-audit.js (screenReaderCompatibilityTask, assistiveTechnologyUsabilityTask)

      }
    }
  }
}
```

## Output Format

```json
{
  "type": "object",
  "properties": {
    "compatibilityMatrix": {
      "type": "object",
      "description": "Screen reader compatibility results"
    },
    "issues": {
      "type": "array",
      "description": "Identified accessibility issues"
    },
    "recommendations": {
      "type": "array",

  }
}
```

## Interaction Model

This agent works best when:
1. Given specific user scenarios to test
2. Provided with component context (purpose, expected behavior)
3. Asked to compare behavior across multiple screen readers
4. Generating actionable remediation guidance
