SYSTEM DOCUMENTATION & REQUIREMENTS

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.

FAQPage Schema
How do I automate QA testing with a persistent headless browser session?

Automate QA testing by running a long-lived headless browser daemon that maintains cookies, tabs, and login sessions across commands. This allows you to execute deterministic browser commands and turn multi-step workflows into reproducible sequences without losing state.

Can I capture screenshots and verify responsive layouts during web application testing?

Yes, you can capture annotated screenshots with element labels and test responsive layouts across devices. Visual verification allows you to diff page states, inspect console and network logs, and verify that interactive elements loaded correctly.

How do I test a checkout flow using Playwright and headless browser automation?

Test a checkout flow by navigating to your staging site, snapshotting interactive elements, and filling forms using stable refs. The headless browser executes commands with sub-second latency, allowing you to verify the success state and collect screenshots for bug reports.

Do I need Playwright installed to run headless browser automation for site dogfooding?

Yes, Playwright and the compiled browse binary are required to execute deterministic browser commands. These dependencies enable the persistent session state and sub-second latency needed for reliable site dogfooding and QA testing workflows.

What is the best way to maintain login state across multiple browser automation commands?

Use a persistent headless browser daemon that auto-starts and maintains session state, cookies, and tabs between commands. This approach eliminates browser QA friction by keeping login sessions active across reproducible testing sequences.
