it would be a nice-to-have for temporary dev environments, e.g do npm run serve in your project dir and it would automatically add a "My App" application in the apps list.

I was thinking it'd also be a good thing to have a timeout, e.g the app would delete itself after 30 minutes with no requests.

@mafredri suggested that you could define apps with YAML and also mentionned that there should be a way to "lock this down or control the available apps" for the template authors.

On the other hand, I was more thinking of a thing like coderagent application add [..] but YAML is fine-ish too, even though it'd remove the "on-the-fly" capacities of it.
