Great questions:

- For extending auth, currently the framework contribution is the main option, but we've intentionally made everything modular so we will be making it extensible with custom external packages as well (or even directly in your app without a package).

- Our system prompt actually doesn't have anything TypeScript specific (only Modelence specific instructions). But the typing system is literally a miracle - the success percentage from a single prompt went from about 30% to 90%+ just by adding the type checks for the agent. It is surprisingly good at self-correcting, to the point that even when it lacks context it ends up going into the framework code itself from node_modules to find the right usage.
