gstack

SKILL.md

Fast headless browser for QA testing, deployment verification, and user flow dogfooding.

Navigate URLs, interact with elements, verify page state, and take annotated screenshots with element labels and reference IDs

Supports responsive layout testing (mobile/tablet/desktop), file uploads, form validation, and dialog handling with auto-accept

Includes snapshot diffing to show exactly what changed after interactions, plus console and network inspection for debugging

Persistent browser state across commands (cookies, sessions, tabs) with ~100–200ms per command after initial startup

When to invoke this skill

Sends any gstack request to the right skill
(planning, review, QA, shipping, debugging, docs, security, design). For browser/QA
and dogfooding it points you at /browse. Use when you invoke gstack without a specific
skill, or ask "which gstack skill fits this?".
