SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manual browser testing, deployment verification, and bug documentation require repetitive actions that are slow and easy to forget. This Skill automates headless browser control so you can navigate pages, interact with elements, capture screenshots, and verify site behavior in seconds.

Core Features & Use Cases

  • Persistent Headless Browser: Auto-starts a Chromium daemon that maintains cookies, tabs, and sessions across commands — first call takes ~3 seconds, subsequent calls take ~100-200ms.
  • Element Interaction & Verification: Navigate URLs, click elements, fill forms, check element states, and diff snapshots to verify UI changes without manual inspection.
  • Visual Evidence Capture: Take full-page screenshots, responsive layout sweeps, annotated snapshots with element refs, and element crops to document bugs or verify designs.

Quick Start

Use the gstack skill to navigate to your staging URL, take a screenshot of the homepage, and verify the page loads correctly by checking for console errors and confirming key elements are visible.

Frequently Asked Questions about gstack

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate headless browser screenshots for QA testing?▼

Automate headless browser screenshots by using a persistent Chromium daemon that executes navigation and interaction commands to capture full-page or annotated snapshots for QA testing.

Can I verify deployed site layouts without manual browser inspection?▼

Yes, you can verify deployed site layouts without manual inspection by automating headless browser navigation and diffing visual snapshots to confirm UI changes and check element states.

How do I capture bug evidence with annotated screenshots during user flow testing?▼

Capture bug evidence with annotated screenshots by automating a headless browser to navigate user flows, interact with elements, and crop visual snapshots with element references for documentation.

Does headless browser automation support responsive layout testing across viewports?▼

Headless browser automation supports responsive layout testing by executing visual regression sweeps across different viewport sizes to capture and compare full-page screenshots automatically.

What do I need to run headless browser automation for deployment checks?▼

To run headless browser automation for deployment checks, you need a persistent Chromium daemon environment configured with Bearer token authentication to execute navigation and inspection commands.

Why does the first headless browser command take longer than subsequent calls?▼

The first headless browser command takes approximately three seconds because it initializes the persistent Chromium daemon, while subsequent calls execute in 100-200ms by reusing the active session.
