But you need to explicitly specify the prompt to check dosage. If you passed it as part of the original extraction model call, it would return a lower confidence to begin with. Or provide a different 'is_dosage_reasonable' value, which would eliminate the need for Jev.

And this is before one argues that dose <= 3 tablets is a better validation than the Jev prompt and costs nothing.

Well yes but then you'd have to manually code every set of expectations, the point of using a model like Jev is it can flag a "something is wrong here" entry without needing someone to define every thing that could go wrong
