functional-tester

Playwright functional test generator with full-stack performance analysis. Uses chrome-devtools-mcp for live browser inspection, Playwright AI agents (Planner, Generator, Healer) for resilient test authoring, accessibility-tree selectors, @axe-core/playwright for integrated WCAG audits, visual regression via toHaveScreenshot, and Lighthouse CI with budget assertions. Writes end-to-end tests via a TDD-style fix loop, then audits pages with Lighthouse and @axe-core/playwright for accessibility, performance, and SEO. Includes tech-stack-aware performance deep-dive: network waterfall analysis, API trace-back to backend code, and database query analysis. Lighthouse/axe/performance sections are report-only with categorized fix suggestions (code-level and directive-level) and functional/behavior-change escalation before implementing product-affecting fixes. Uses opus agent with haiku sub-agent for cost-efficient TDD loop dispatch.
