By the way, the excellent discussion here got me thinking about the next logical step for vet: supporting private environments.
Running public scripts is great, but what about running deployment scripts from a private GitHub repo or setup scripts from an internal server?
Based on this, I've opened a new feature request to add authentication support to vet, with a roadmap that includes .netrc support, a VET_TOKEN environment variable, and a future goal of integrating with secret managers like HashiCorp Vault by reading tokens from stdin.
If you're interested in that direction, I'd love to get your thoughts on the feature request over on GitHub:

Thanks again for all the great feedback!
