What problem does it solve? After making frontend code changes, developers often assume the fix works without checking, leading to broken layouts, console errors, and failed interactions reaching users. This Skill closes that gap by autonomously opening the app in a browser, observing the actual rendered state, and iterating fixes until the change is confirmed working. ## Core Features & Use Cases - Autonomous verification loop: Observe the page, compare against success criteria, fix failures, and re-verify, with a circuit breaker after three failed attempts on the same issue. - Token-efficient inspection: Uses the agent-browser CLI accessibility tree with element refs for structure checks, reserving screenshots for layout and styling verification. - Debugging support: Inspects console messages, page errors, and failed network requests to root-cause issues before escalating. - Use Case: After fixing a login form bug, the Skill opens the login page, fills credentials via element refs, submits, re-snapshots after navigation, and confirms the dashboard renders correctly. ## Quick Start Verify in the browser that the frontend change you just made works correctly on the local app.
