You don't need to use gcloud if you already have:

1. A GCP project (needed for OAuth) 2. Enabled APIs in said project

You can skip that setup if you already have the OAuth credentials.

There are many gotchas in this process and unfortunately there is no easy way to deal with the OAuth setup.

Yeah, still no way around this unfortunately.

I was using Jules for AI assistance with my blog (tagging, components, linking, etc), but git LFS stopped working and I decided to reassess its usage in today's dev environment.
