I really love the idea of "View source" for base prompts.
If we simply treat the prompts as frontend / client-side (one could even argue that it can be harder to get the original code from a JS bundle than extract a prompt using prompt injection), then function calling (the backend API) could be where folks add additional value, and if reasonable, charge for it.
As long as you can audit the function calls and see what's sent and received, same as you can do with a browser, then I think it becomes closer to a familiar and well-tested model.
My thoughts exactly. It's impressive that despite relying on BFS, the tool manages to be so fast on a tiny node on google cloud. Even when there's a depth of >= 5 !
