Environments

An environment gives agents something to observe and act on. ASTRA supports two environment interfaces: CArtAgO for shared Java artifacts, and EIS for environments implementing the Environment Interface Standard.

Choose an environment interface

Interface	Environment model	How agents interact	Guide
CArtAgO	Artifacts in workspaces expose operations, observable properties and signals	Join a workspace, discover or create artifacts, then focus and operate	CArtAgO environments
EIS	Environment JARs expose controllable entities, actions and percepts	Launch or join an environment, link to entities, then perceive and act	EIS environments

Both guides follow the same sequence: concepts, project setup, environment use, observations, sharing, failures and an API summary. Complete the Quick Start first. These adapters are separate dependencies from the core API library.
