Install
npx @pascal-app/cli editor
For an agent

Use it for architectural and interior layouts that a person and an agent edit together. It is a full editor, so treat it as an app to run, not a component to embed.

Why it is here. It is a large open-source example of a 3D editor built for both people and agents.
