Yeah, this is something we've heard as well. No particular feature right now but we did ship an agent in local dev to help people improve their prompts.
Do you think that a lot of these components like observability and evals will eventually be consumed by either providers (like OpenAI) or an orchestration framework like Mastra (when using multiple providers, though even if you're using just one provider for many tasks I can see it belonging to the orchestration framework)?
