Design guide adopted.
The Hatchery now ships every surface against the Brand, Doc, and Pet tests before merge.
build note · hatchery.pet

The marketplace, docs, and install path start from the same question: where does an agent actually belong.

A small note from the person building the product.
GD
I built The Hatchery for the moment when Codex stops feeling like a window and starts feeling like a place.
The pets are tiny, but the product around them should be serious: clean docs, copyable commands, honest pricing, and art that earns its pixels.
The goal is simple: make something OpenAI engineers would inspect, understand, and remember.
