# Internal agents

> Run your own agent next to Sidekick, in Ask Sidekick.

[Sidekick](/docs/product/agents/sidekick) is the built-in internal agent. You can run your own in the same place:

* Click **Ask Sidekick** from any page and pick your agent
* Send a prompt. The agent posts messages and tool calls. Sensitive actions wait on **Approve** or **Deny**
* Start one automatically with the **Start Sidekick discussion** [workflow](/docs/product/workflows) step
