What problem does it solve? Frontend changes often look correct in code but break in the browser, and a quick visual glance misses console errors, failed network requests, and broken interaction states. This Skill runs a real verification pass against a running local app and returns a structured findings report instead of a vague "it renders" claim. ## Core Features & Use Cases - Dev Server Management: Finds the correct run command from repo docs or package.json, reuses an already-running server, and waits until the app is actually reachable. - Real Flow Exercising: Walks the actual user path relevant to the change, covering modals, form validation, navigation, loading states, and edge cases beyond the happy path. - Browser Signal Inspection: Captures console errors, failed network requests, layout breakage, and interaction regressions, plus a mandatory final-state screenshot as evidence. - Use Case: After implementing a new checkout form, ask the agent to verify it locally; it starts the dev server, submits valid and invalid inputs, checks console and network traffic, screenshots the result, and reports a Pass/Fail verdict with findings. ## Quick Start Verify my recent UI changes by starting the dev server, opening the affected page in the browser, exercising the flow, and reporting any console or layout issues.
