Pre-Repository Creation / Validation webhooks


I work at an organization that has a Github Enterprise account. And, we were thinking about enforcing naming conventions or other organizational policies during the repository creation process. I was wondering if there was a webhook that would execute during the creation of repository (within an organization) which would validate the creation request? Something that could be used to check if the naming policy is being followed and prevent the creation if it didn’t pass validation?

I imagine others have sought something similar before. Do you know of any previous work that might guide us to a practical solution?
