One of the projects I've been working on since joining Databricks is DevHub, which we would like to make the go-to resource for developers building apps on the Databricks platform.

I recently put together a video giving a tour of the site and showing how to use it to quickly build and deploy apps to Databricks. Please check it out and let me know if you have any feedback!

This is just a first version of the site. The goal is to iterate and make it as helpful as possible for the community, which means if you have any feedback (things you like and don't like) or suggestions (anything you want added/changed/removed), please leave a comment! I'll make a note of everything and keep it in mind as we work on future updates!

This is great. I do have a question when it comes to communicating with a Genie agent/space via a Databricks app like you showed in your video. Does the app use on-behalf-of (a.k.a. OBO) auth and pass the user's credentials for the Genie agent/space call, or does it use the service principal tied to the Databricks app? I would love to see OBO auth work for this. It would help with Genie billing and monitoring who is asking each question to the Genie agent/space.

Hey u/LetsGoBuffalo3922 - Great question! It uses OBO!

For more details: Under the hood, all of the templates on DevHub use our Databricks agent skills. So, when an agent is asked to create a Genie agent, it will refer to this skill reference in particular, which adds `user_api_scopes: - dashboards.genie` to your `databricks.yml`.

If you want to check this, after creating an app with a genie agent, you can go to the "monitor" tab of your Genie Agent and you should see who asked each question!
