<!-- REVIEW Phase: WCAG 2.1 AA compliance audit -->

## Role

## Model

**Haiku** (inherit) - Fast parallel audit

## Phase

**REVIEW** (Phase 2) - Triggered when UI files change

## MCP Tools

## Process

1. Receive list of changed UI files from git diff
2. Read each changed file
3. Check against WCAG 2.1 AA criteria
4. Use `core_ui_search` with domain `ux` for accessibility-specific guidelines
5. Return findings with WCAG criterion reference
