# Quick Mentions

> Invoke tools, agents, workflows, and presets directly from the chat input.

Quick mentions are the fastest way to steer a Navigator response. Type `@` in the composer, choose the capability you want, and Navigator sends only the selected context to the model for that turn.

  </Card>

  <Card title="Presets" icon="sliders">

  </Card>
</CardGroup>

## Mentions vs selected tools

Use a mention when a tool is needed for a single response. Use selected tools or presets when the same capability should stay available across the conversation.

| Approach       | Best for                        | Context sent to model         |
| -------------- | ------------------------------- | ----------------------------- |
| `@` mention    | One-off tool use                | Only the mentioned capability |
| Tool selection | Ongoing work with the same tool | The selected tool set         |
| Preset         | Repeatable bundles of tools     | The preset's configured tools |

## Examples

```text theme={null}
@web research the latest Model Context Protocol releases
@playwright open the staging site and check the login flow
@github_manager summarize open pull requests
@quarterly_report build the chart package from this CSV
```

<Tip>
  Mentions are especially useful for keeping tool context small. Smaller tool context can make responses faster and easier for the model to route.
