# Assistants

> An Assistant is an instance of a supported harness running on a connected server.

An Assistant is an instance of a harness running on one of your connected servers. RelayCloud connects to the assistant, records its conversations, and lets you connect to it any way you want.

## Agents

Each assistant can have multiple agents. An agent bundles common configuration into reusable profiles:

* A **system prompt** that defines how the assistant behaves
* A **model preference** for which model and provider it uses
* **Tool permissions** that control what the assistant can do

When you start a conversation, you can select which agent the assistant should use. You can also add your own agents through the harness configuration.

## Supported harnesses

RelayCloud currently supports OpenCode as a harness for Assistants.

* OpenCode

## More harnesses coming soon

Support for more harnesses is coming soon:
