# Cosmos Experts

> Reusable agent configurations for engineering workflows like authoring code, reviewing code, investigating incidents, and more.

## Overview

An **Expert** is a reusable agent in Cosmos. It packages a system prompt, user instructions, integrations, environment, model, and workers that make a repeatable engineering workflow feel like a product surface instead of a one-off prompt.

## How to Engage an Expert

* **Start a Session**: From the Cosmos sidebar, click New Session and select an Expert to begin chatting, coding or kicking off a task.
* **Schedule It**: Set a recurring schedule and timezone for the Expert to run under [Automations](/cosmos/automations).
* **Automate It**: Trigger your Expert using event-based integrations with GitHub, GitLab, Linear, Slack, PagerDuty, and more.

## Sharing Your Expert

You have full control over who gets to use your Expert. Choose the level of access that works best for your workflow:

* **Private**: Keep your Expert completely private for your own personal use.
* **Specific teammates**: Invite specific team members to use your Expert.
* **Spaces**: Restrict access to a specific [Space](/cosmos/spaces/overview) so only relevant groups can use your Expert.
* **Organization**: Share with your entire organization.

## 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.

<Note>The fastest way to set up an Expert is to ask [Cosmos Advisor](/cosmos/advisor/overview) to do it for you — and it's strongly recommended to manage Experts by prompting the Advisor rather than hand-editing the configuration form. Describe the workflow you want in plain language and the Advisor deploys a Template Expert or designs a custom one end-to-end — picking the environment, capabilities, and triggers — rather than you configuring it by hand.</Note>

## Next steps

* [Cosmos Advisor](/cosmos/advisor/overview) — have the Advisor set up and tune Experts for you conversationally.
* [Template Experts](/cosmos/experts-templates) — start from a built-in Template Expert for common SDLC workflows.
* [Configure a custom Expert](/cosmos/experts-configure-custom) — create a team-specific Expert when no template fits.
* [Delegating Work](/cosmos/workers-subagents) — learn how Experts delegate work to other agents.
* [Triggers, Subscriptions, and Integrations](/cosmos/experts-triggers-subscriptions-integrations) — understand how Experts respond to events and interact with the outside world.
