Accessibility Auditor — ultrathink

Overview

Execute a comprehensive accessibility, visual regression, and performance audit on the BoardClaude dashboard using Playwright MCP. Captures screenshots at multiple viewports, runs axe-core violation checks, validates color contrast for all agent colors, tests keyboard navigation, and produces Lighthouse scores. Results feed into Lydia and Ado agent evaluations as structured context.

Prerequisites

Before running, verify:

• •Playwright MCP available: !echo "Check mcp__playwright tools are registered"
• •Dev server running: !curl -s -o /dev/null -w "%{http_code}" http://localhost:3000 || echo "NOT RUNNING"
• •Node modules: !ls node_modules/.package-lock.json 2>/dev/null || echo "NOT FOUND — run npm install"
• •Validation directory: !ls .boardclaude/validation/ 2>/dev/null || echo "NOT FOUND — will create"

Steps

1. •

   Ensure dev server is running: Check curl -s http://localhost:3000. If not responding, start it with npm run dev & and wait up to 15 seconds for it to become available. If it still fails, abort Lighthouse steps and note in report.

2. •

   Prepare output directory: Ensure .boardclaude/validation/screenshots/ exists. Create it if missing.

3. •

   Use Playwright MCP to navigate to key pages: /, /audit/latest, /dashboard. For each page:

   a. Take screenshot at default viewport (1440px wide). Save to .boardclaude/validation/screenshots/{page}-{timestamp}.png.

   b. Run axe-core accessibility audit via browser_evaluate. Inject axe-core from CDN, run axe.run(), and collect violations. Record each violation with its impact level (critical, serious, moderate, minor), affected nodes, and WCAG criteria.

   c. Check color contrast ratios against the agent color palette:

   • •Boris=#3b82f6, Cat=#8b5cf6, Thariq=#06b6d4, Lydia=#f59e0b, Ado=#10b981, Jason=#ef4444, Synthesis=#6366f1
   • •Verify each agent color meets WCAG AA contrast ratio (4.5:1 for normal text, 3:1 for large text) against both the dark background and any card backgrounds.

   d. Verify keyboard navigation: Use Playwright to tab through all interactive elements. Check that focus indicators are visible, tab order is logical, and no focus traps exist.

   e. Check responsive layout at three viewports: 1440px, 768px, 375px. Take a screenshot at each breakpoint. Flag layout overflow, overlapping elements, or unreadable text.

4. •

   Run Lighthouse audit via Playwright: Navigate to each page and collect scores for performance, accessibility, best practices, and SEO categories. Average scores across all pages.

5. •

   Save results to .boardclaude/validation/accessibility.json in the output format below.

6. •

   Feed results to agents: Format the accessibility report as structured context and make it available to the Lydia agent (code quality / patterns) and the Ado agent (documentation / integration) for their next evaluation cycle.

Error Handling

• •Playwright MCP unavailable: Skip all visual testing (screenshots, keyboard nav, responsive checks). Note "playwright_available": false in the report. Fall back to static analysis of component source files for accessibility patterns (e.g., missing alt text, missing aria labels).
• •Dev server won't start: Skip Lighthouse and all browser-based checks. Use static analysis only. Note "dev_server": false in the report.
• •Dashboard not built yet: Report "dashboard_status": "not_available" and exit gracefully with a skeleton report. This is expected during early hackathon days.
• •axe-core CDN unreachable: Bundle a local copy as fallback. If both fail, skip axe audit and note in report.
• •Page navigation fails: Record the page as "status": "error" in the report and continue with remaining pages. Do not abort the entire audit for a single page failure.
