I'd prefer taking a step back to see if this is the right approach or if this safety can be solved in a much simpler way. Looking at the title of the submission I don't consider it practical. I would welcome any other ideas, I'm thinking along the lines of a simple and boring bff which does the parsing and validation and sending strongly typed objects to the front end.

I've been thinking about this approach. How do you handle updates on this setup? For example, a status component that goes from "loading" to "success".

Does the LLM go back and modify the previous response, sending deltas to the client? Effectively changing the component from loading to success. Or is something else happening behind the scenes?

I use assistant-ui to handle my frontend rendering. It would make sense for them to adopt something like this
