# File Analyst

File Analyst
============

An agent that downloads files shared in Slack, analyzes their content,
and can upload results back to the channel.

Key concepts:
  - ``SlackTools`` with ``enable_download_file`` and ``enable_upload_file``
    gives the agent access to Slack's file APIs.
  - Works with CSV, code, text, and other file types.
  - Uses Claude for strong document comprehension.

Slack scopes: app_mentions:read, assistant:write, chat:write, im:history,
             files:read, files:write, channels:history

## Run the Example

<Steps>
  <Snippet file="create-venv-step.mdx" />

  <Step title="Install dependencies">
    ```bash theme={null}
    uv pip install -U "agno[os,slack]" anthropic
    ```
  </Step>

  <Step title="Export environment variables">
    <CodeGroup>
      ```bash Mac/Linux theme={null}
      export ANTHROPIC_API_KEY="your_anthropic_api_key_here"
      export SLACK_SIGNING_SECRET="your_slack_signing_secret_here"
      export SLACK_TOKEN="your_slack_token_here"
      export SLACK_USER_TOKEN="your_slack_user_token_here"
      ```

      ```bash Windows theme={null}
      $Env:ANTHROPIC_API_KEY="your_anthropic_api_key_here"
      $Env:SLACK_SIGNING_SECRET="your_slack_signing_secret_here"
      $Env:SLACK_TOKEN="your_slack_token_here"
      $Env:SLACK_USER_TOKEN="your_slack_user_token_here"
      ```
    </CodeGroup>
  </Step>

  <Step title="Configure Slack">
    Complete [Slack setup](/agent-os/interfaces/slack/setup): create and install the app, expose the server through public HTTPS, and add the scopes listed in the example. The default event request URL is `<public-url>/slack/events`; HITL examples also use `<public-url>/slack/interactions` for interactivity. Use any custom prefix shown in the example instead of `/slack`.
  </Step>

  <Step title="Run the example">
    Save the code above as `file_analyst.py`, then run:

    ```bash theme={null}
    python file_analyst.py
    ```
  </Step>
</Steps>
