What problem does it solve? Verifying UI behavior that depends on real browser focus, keyboard input, scrolling, or rendering is hard to do from code alone. This Skill builds or reuses a local browser/CDP harness to drive a web, IDE, or Electron app and capture concrete evidence of its behavior. ## Core Features & Use Cases - Local UI Automation: Connect to a dev server or a Chromium/Electron remote debugging port and interact with the app using accessibility roles and stable selectors. - Evidence Capture: Take screenshots, accessibility snapshots, console logs, network logs, CPU profiles, traces, and heap snapshots for before/after comparisons. - Structured Interaction Loop: Perform one structural action at a time (click, type, scroll, resize) and verify the resulting state change with fresh snapshots. - Use Case: You fixed a rendering bug in an Electron app. Launch it with a remote debugging port, connect over CDP, select the correct window by an app-root marker, reproduce the bug scenario, and save before/after screenshots as proof. ## Quick Start Start the app locally and use this Skill to connect to it with Playwright or CDP, reproduce the UI issue, and capture a screenshot showing the result.
