While not specific to 12factor question. With any of these agents and solutions how is LLM Ops being handled? Also, what's the testing strategy and how do I make sure that I don't cause regression?

i try not to take a hard stance on any tool or framework - the idea is take control of the building blocks, and you can still bring most of the cool LLM ops / LLM observability techniques to bear.

I could see one of the twelve factors being around observability beyond just "whats the context" - that may be a good thing to incorporate for version 1.1
