What problem does it solve?
Manual web application testing is slow, inconsistent, and hard to reproduce across team members. This skill eliminates browser QA friction by providing a persistent, scriptable headless browser that maintains state between commands.
Core Features & Use Cases
- Persistent Browser Sessions: Auto-starts a long-lived Chromium daemon that maintains cookies, tabs, and login sessions across commands, turning multi-step browser workflows into reproducible sequences.
- Visual Verification & Debugging: Capture annotated screenshots with element labels, diff page states to verify interactions worked, inspect console and network logs, and test responsive layouts across devices.
- Use Case: Test a checkout flow by navigating to the staging site, snapshotting interactive elements, filling forms using stable refs, verifying the success state, and collecting screenshots for bug reports.
Quick Start
Use the gstack browse skill to verify the staging deployment at https://staging.yourapp.com by navigating to the site, checking for console errors, taking a screenshot, and confirming the dashboard loads correctly.
