CNAME

# Assuming the repository is in Python

def create_cname_file():
    file_path = "CNAME"
    content = "www.agiaify.info"

    with open(file_path, "w") as file:
        file.write(content)

create_cname_file()
```

Unit Test:
```python
def test_create_cname_file():
    # Create a temporary directory for testing
    with tempfile.TemporaryDirectory() as temp_dir:
        # Set the current working directory to the temporary directory
        os.chdir(temp_dir)

        # Call the function to create the CNAME file
        create_cname_file()

        # Check if the CNAME file exists
        assert os.path.exists("CNAME")

        # Read the content of the CNAME file
        with open("CNAME", "r") as file:
            content = file.read()

        # Check if the content is correct
        assert content == "www.agiaify.info"
