# Task
Using the dg CLI (Deepgram), transcribe a sample audio file:

1. Download this sample audio file:
   https://storage.googleapis.com/aai-web-samples/5_common_sports_injuries.mp3
2. Use the dg CLI to transcribe the audio file
3. If the CLI expects a local file path, use the downloaded file
4. Print the transcribed text to stdout

Use the CLI directly for the operation — do not use the Python SDK.

You MUST use the `dg` CLI to accomplish this task.
Do NOT write Python scripts that import the SDK — use CLI commands via the terminal.

If you need help with CLI commands, check the documentation: https://github.com/deepgram/cli
You can also use `dg --help` and `dg <command> --help` to discover available commands.

## Setup
You need to install and authenticate the `dg` CLI yourself.

### Installation
Run: `pip install deepctl`

### Authentication
The following environment variables are already set in this environment: `DEEPGRAM_API_KEY`
The CLI should pick these up automatically, or pass them to commands as needed.

## Execution
1. Install the `dg` CLI using the command above
2. Verify the installation: `dg --help`
3. Authenticate using the credentials above
4. Perform the task described above

Work in the /home/daytona/app directory. Run commands and print output to stdout.
If there are errors, debug and fix them until the task runs successfully.

## Summary
When you are done, write a JSON summary file to /home/daytona/app/results.json with this structure:
{
  "operations": [
    {"step": 1, "description": "What you did", "command": "the CLI command", "success": true/false, "output_summary": "brief result"},
    ...
  ],
  "overall_success": true/false,
  "notes": ["any relevant notes about the execution"]
}
