# Custom Agents

> Specialized AI agents that power Agentic Applications.

Custom Agents are specialized AI agents configured with the right skills, tools, knowledge, and permissions for a defined use case.

They are the backend of Agentic Applications. They accept text, files, and images, and can return text or run tasks on behalf of the user.

## When to use a Custom Agent

Use a Custom Agent when a workflow needs an agent that is shaped for a specific job - a Redshift Analyzer, a customer escalation triager, or a KYC reviewer - rather than a general assistant.

## Examples

Custom Agents come in many shapes. Here are a few built for specific business workflows:

<Tabs>
  <Tab title="DataSec Review">
    A custom agent built for secure code review and live analysis. It scans a codebase for vulnerabilities and writes a detailed report with fixes, checks current CVEs and security advisories, and generates a live, interactive report of findings and remediation steps in the chat.

## What a Custom Agent includes

Every Custom Agent brings together a model that powers its reasoning, the skills and tools it uses to take action, and the knowledge and data access it needs for the systems it works with. A system prompt defines its role and output, while permissions control what it can do automatically.

## How they power applications

A Custom Agent does the work behind an Agentic Application's frontend. The application presents chat, live surfaces, and reports; the Custom Agent understands the task, uses tools, accesses data, and performs the actions.

To configure a Custom Agent's backend, see [Manage Agents](/guides/omni/manage-agents/agent-configuration).
