# Create a sub-agent {#ariaid-title1}

Release version: Brazil  
Updated September 27, 2026

Create a custom sub-agent to hand off a specialized task, such as code review or security analysis, to a reusable agent with focused instructions and limited access. A narrow scope helps produce consistent results, limiting
the sub-agent to only the skills and MCP servers it requires.

## Before you begin

Role required: sn_app_arc.user

## Procedure

1. Navigate to SettingsSub-Agents.
2. Select the add icon.  
   The New Sub-Agent dialog opens.
3. Enter the sub-agent details.  
   {#create-sub-agent__table-subagent-fields__entry__2}

   | Field | Description |
   |-|-|
   | Name (slug format) | Unique name in lowercase letters and hyphens only, used to reference the sub-agent in `spawn_subagent`. |
   | Description | A short summary of what the sub-agent does. |
   | Skills (optional) | The skills the sub-agent can use. |
   | MCP Servers (optional) | The MCP servers the sub-agent can use. |
