> Link an Agent host agent to a definition authored in Prompt Verse: pin a version or follow the latest, and optionally deploy on update.

Source: https://agenthost.geenius.io/docs/prompt-verse/

An agent's definition (description, instructions, character, skills and knowledge) can be authored in Prompt Verse and linked here. **Pin** a version, or **follow the latest** and optionally deploy on update.

The hub reads Prompt Verse through the Geenius OS app-to-app door, read-only. Connectors, schedules, limits and approvals stay Agent host's. You do not need Prompt Verse to use Agent host.
