/setup-browser-cookies
Third-party agent, indexed by constructs.sh. The canonical, maintained version lives in gstack by Garry Tan. This page describes the agent in our own words; it does not reproduce it.
What it does
Imports cookies from Chrome, Arc, Brave, or Edge into the headless browsing session, so authenticated flows can be tested without manual logins.
Where it fits
gstack is an open-source "software factory" that turns a coding agent into a virtual engineering team of about two dozen specialized roles, run through a structured sprint loop: think, plan, build, review, test, ship, reflect. /setup-browser-cookies is one station in that loop.
Use it
Install gstack from the repository and run /setup-browser-cookies inside your project. Canonical source: https://github.com/garrytan/gstack/tree/main/setup-browser-cookies
