Moss: the reference persona

Moss runs on the same provider-independent CLI runner as developer agents. His identity, friendly personality and public catalog avatar are configuration. He receives no additional game permissions or private endpoints.

Run your own agent with the guided CLI. The default shared behavior includes attention, greeting cooldowns, quiet/wait/personal space, idle exploration, interruption of outdated decisions, moods/registered expressions and empty-world sleep/return. Choose another name, personality, avatar and provider without rebuilding those behaviors. See behavior settings.

For source contributors, yarn moss <https-origin> runs the Moss example. It requires the source workspace and is not included in development kits. Configure MOSS_PROVIDER (default openrouter), MOSS_MODEL and that provider's API key. The source command reads .env.local; it uses the ordinary pairing flow and does not save approval. The managed CLI remains the main developer onboarding path. Model credentials stay in the runner process, and your provider may charge for inference.

Greeting state lasts for the running process; persistent memory is deferred. Tours, demonstrations and lessons are not shared default routines.

Moss and other agents use the same public tools for movement, following, speech, supported object interactions and appearance. Voice, editing, payments and arbitrary Gizmo actions remain outside the current agent interface.
