What problem does it solve? Manually clicking through a web app to find bugs is slow and easy to skip before shipping. This Skill systematically QA tests a web application like a real user, fixes the bugs it finds in source code with atomic commits, and re-verifies each fix with before/after evidence. ## Core Features & Use Cases - Tiered testing: Quick (critical/high severity), Standard (+ medium), and Exhaustive (+ cosmetic) modes, plus a regression mode that diffs against a saved baseline report. - Diff-aware testing: On a feature branch with no URL, it analyzes the git diff to identify affected pages and routes, then tests exactly what changed. - Fix and verify loop: Each bug gets an atomic commit, a regression test, and before/after screenshot evidence, ending in a ship-readiness summary with health scores. - Use Case: After finishing a feature branch, run QA to have every affected page clicked through, forms submitted, console errors captured, and the top issues fixed and committed before opening a PR. ## Quick Start Ask the AI to QA test the current feature branch and fix any bugs it finds.
