Hey Hey - Thanks for your awesome project. I very much like you focus and being minimalistic but effective!
It's only one feature I'm missing: the option ensure the (expected) input schema are valid and make sense. E.g to avoid typos or (enum) values which doesn't make sense. I could see very effective in valuable in combination with json-schema.
One way could be a (cli) validator giving feedback on demand, or even the editor provides suggestions and does in-time validation to prevent wrong specification in first place - wyt?
