as prior comment re: yaml.
if an untrusted party can influence output_folder, they could overwrite files anywhere on the filesystem.

Mid-to-high level of AI involvement in code generation to be noted for potential hidden security flaws.

This code in it's current state is okay to be run in local, trusted environments, where the attack surface is controlled. But would not be ready to use in a public-facing app.
