SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires playwright, diff.

What problem does it solve?

Traditional QA workflows are slow and brittle, requiring manual browser interactions and manual captures of evidence. gstack provides a persistent headless browser that you can drive with simple commands to automate navigation, content reading, interactions, diffs, and annotated screenshots for bug reports and QA validation.

Core Features & Use Cases

  • Persistent headless Chromium daemon that stays alive across commands for sub-second responses.
  • Navigate, read, interact, diff, screenshot, and test responsive layouts in real-world QA scenarios.
  • Produce evidence for bugs and deployments by capturing annotated screens and diffs, then feed results into PRs or bug reports.

Quick Start

Invoke the browse skill to navigate to a URL and run QA checks.
