Overview
An Expert is a reusable Cosmos agent configuration. It packages the workflow instructions, integrations, runtime environment, model, launch guidance, workers, and triggers that make a repeatable engineering workflow feel like a product surface instead of a one-off prompt. Experts are the most powerful Cosmos concept. When one AI-forward engineer perfects an Expert and shares it with the organization, everyone can start standardized, high-quality agent sessions for that workflow. This lets the productivity gains from your most advanced agent users benefit the entire team.What an Expert includes
An Expert brings together everything Cosmos needs to run a repeatable agent workflow:- Identity and sharing: a display name, description, visibility, and stable Expert ID.
- Instructions: the system prompt, optional default system prompt, user-facing instructions, and placeholder text shown when someone starts a session.
- Model: the model the Expert uses by default, with room for managed alternatives as the workflow evolves.
- Capabilities and integrations: the tools the Expert can use, such as web access, code hosting, ticketing, communication, or organization-specific integrations.
- Environment: the VM, runtime environment, repositories, and resources the Expert uses when it runs.
- Launch experience: initial messages, user instructions, and input guidance that make it clear what someone should provide.
- Workers: the other Experts this Expert can launch for delegated tasks, plus whether it can use all available Experts as workers.
