# Using Agents

> Call deployed agents from your app with the SDKs

This page covers the app-side integration path:

* create a filesystem
* create a task
* send events
* inspect messages and files

## Client Setup

<CodeGroup>
  ```typescript TypeScript theme={"dark"}
  import { TerminalUseClient } from '@terminaluse/sdk';

  const client = new TerminalUseClient({
    environment: process.env.TERMINALUSE_BASE_URL ?? 'https://api.terminaluse.com',
    bearerAuth: { token: process.env.TERMINALUSE_API_KEY! },
  });
  ```

  ```python Python theme={"dark"}
  from terminaluse import AsyncTerminalUse

  client = AsyncTerminalUse(token="your_api_key")
  ```
</CodeGroup>

## Create A Filesystem

Filesystems belong to projects. Projects are the permission boundary; filesystems are the storage.

<CodeGroup>
  ```typescript TypeScript theme={"dark"}
  const project = await client.projects.create({
    namespace_id: 'ns_123',
    name: 'my-project'
  });

  const filesystem = await client.filesystems.create({
    project_id: project.id,
    name: 'customer-123'
  });
  ```

  ```python Python theme={"dark"}
  project = await client.projects.create(
      namespace_id="ns_123",
      name="my-project"
  )

  filesystem = await client.filesystems.create(
      project_id=project.id,
      name="customer-123"
  )
  ```
</CodeGroup>

## Put Files Into It

There are three different file flows:

| Use case                                         | Surface                                                          |
| ------------------------------------------------ | ---------------------------------------------------------------- |
| Upload or download the entire filesystem archive | `tu fs push` / `tu fs pull` or `getUploadUrl` / `getDownloadUrl` |
| Upload or download one file                      | `uploadFile` / `download_file` / `downloadFile`                  |
| Sync `/workspace` inside the running agent       | Python ADK `sync_down` / `sync_up`                               |

See [Workspaces and Filesystems](/concepts/workspaces-and-filesystems) for the full breakdown.

## Create A Task

Attach either an existing filesystem or a project:

<CodeGroup>
  ```typescript TypeScript theme={"dark"}
  const task = await client.tasks.create({
    agent_name: 'my-namespace/my-agent',
    filesystem_id: filesystem.id,
    params: {
      goal: 'summarize this repo'
    }
  });
  ```

  ```python Python theme={"dark"}
  task = await client.tasks.create(
      agent_name="my-namespace/my-agent",
      filesystem_id=filesystem.id,
      params={
          "goal": "summarize this repo"
      },
  )
  ```
</CodeGroup>

If you pass `project_id` instead of `filesystem_id`, Terminal Use creates a filesystem for the task automatically.

## Send Events

<CodeGroup>
  ```typescript TypeScript theme={"dark"}
  await client.tasks.sendEvent({
    task_id: task.id,
    content: {
      type: 'text',
      text: 'please analyze the files'
    }
  });
  ```

  ```python Python theme={"dark"}
  from terminaluse.types import TextPart

  await client.tasks.send_event(
      task_id=task.id,
      content=TextPart(text="please analyze the files"),
  )
  ```
</CodeGroup>

## Inspect Files

### File Metadata And Content

<CodeGroup>
  ```typescript TypeScript theme={"dark"}
  const files = await client.filesystems.listFiles({
    filesystem_id: filesystem.id,
    recursive: true
  });

  const file = await client.filesystems.getFile({
    filesystem_id: filesystem.id,
    file_path: 'output/report.md',
    include_content: true
  });
  ```

  ```python Python theme={"dark"}
  files = await client.filesystems.list_files(
      filesystem_id=filesystem.id,
      recursive=True,
  )

  file = await client.filesystems.get_file(
      filesystem_id=filesystem.id,
      file_path="output/report.md",
      include_content=True,
  )
  ```
</CodeGroup>

### Single-File Download

<CodeGroup>
  ```typescript TypeScript theme={"dark"}
  const response = await client.filesystems.downloadFile({
    filesystem_id: filesystem.id,
    path: 'output/report.md'
  });
  ```

  ```python Python theme={"dark"}
  chunks = client.filesystems.download_file(
      filesystem_id=filesystem.id,
      path="output/report.md",
  )
  ```
</CodeGroup>

For whole-filesystem transfers, use `tu fs push`, `tu fs pull`, `getUploadUrl`, or `getDownloadUrl` instead.
