What problem does it solve? Manually clicking through a web app to find bugs is slow and inconsistent, and teams often ship changes without verifying pages actually work. This Skill performs systematic browser-based QA testing and produces an evidence-backed report — without ever modifying your code. ## Core Features & Use Cases - Report-only testing: Explores pages, fills forms, clicks interactive elements, and documents issues with screenshots and repro steps, but never fixes anything. - Multiple modes: Diff-aware mode tests only pages affected by your feature branch, Quick mode runs a 30-second smoke test, and Regression mode diffs results against a saved baseline. - Health scoring: Computes a weighted 0-100 health score across console errors, links, visual, functional, UX, performance, content, and accessibility categories. - Use Case: You just shipped a new checkout flow on a feature branch. Run the Skill with no URL and it auto-detects your local dev server, tests the pages changed in your diff, and writes a report with screenshots and a health score to .gstack/qa-reports/. ## Quick Start Ask the agent to run a report-only QA pass on your local app at localhost:3000 and produce a structured bug report with screenshots.
