# Custom Tools

## What are Custom Tools?

Tools are capabilities that agents use to do work. Think of them as skills or functions the agent can perform.

### Agent Missing Required Tools

**Issue:** Agent can't do something it should be able to do

**Solutions:**

```
1. Check tool selection
   - Did you enable the right tools?
   - Are all necessary tools included?

2. Review tool documentation
   - Understand what each tool does
   - Match tools to your needs

3. Ask agent directly
   - "What tools do you have available?"
   - "Can you [specific task]?"
```

## Custom Tools vs Integrations

**What's the difference?**

<CardGroup cols={2}>
  <Card title="Custom Tools" icon="wrench">
    **Built into Emergent**

    * File operations
    * Testing capabilities
    * Search and analysis
    * Internal workflows

    **Platform features**
  </Card>

  <Card title="Integrations" icon="plug">
    **External services**

    * Stripe, Twilio, etc.
    * Third-party APIs
    * Cloud services
    * External platforms

    **Outside connections**

**Both work together!**

* Custom agent uses tools (internal capabilities)
* Integration tools connect to external services
* Combined = powerful custom workflows
