check_category and metadata_vs_api are very similar

[simoncozens]

For both of them:

description = (
    "This script compares the info on local METADATA.pb files"
    " with data fetched from the Google Fonts Developer API.\n\n"
    " In order to use it you need to provide an API key."
)

and there's a lot of common code. We need to choose one and kill the other. metadata_vs_api looks more complete.

I'd say kill both. I've personally never used these tools. The backend team's fork of gftools has diverged so much I think we'll be able to do this without upsetting anyone.
