What problem does it solve? Manually verifying that a deployed feature actually works across pages, viewports, and user journeys is slow and error-prone. This Skill automates post-deploy QA by driving a real browser to catch console errors, broken links, layout regressions, and accessibility violations before users do. ## Core Features & Use Cases - Smoke Testing: Checks console errors, failed network requests, and Core Web Vitals (LCP, CLS, INP) on desktop and mobile viewports. - Interaction & Journey Testing: Clicks navigation links, submits valid and invalid form data, and exercises auth flows and critical user journeys with read-only safety defaults. - Visual Regression & Accessibility: Captures screenshots at 375px, 768px, and 1440px breakpoints, compares against baselines, and runs axe-core WCAG 2.2 AA audits. - Use Case: After deploying a new checkout page to staging, run this Skill to verify forms, screenshots, and accessibility, then receive a structured QA report with a SHIP / SHIP WITH FIXES / DO NOT SHIP verdict. ## Quick Start Run a browser QA pass on the staging deployment at https://staging.example.com and report any console errors, broken interactions, visual regressions, and accessibility violations.
