I have had fairly bad luck specifying the JSONSchema for my structured outputs with Gemini. It seems like describing the schema with natural language descriptions works much better, though I do admit to needing that retry hack at times. Do you have any tips on getting the most out of a schema definition?

Always have a top level object for one.

But also Gemini supports contrained generation which can't fail to match a schema, so why not use that instead of prompting?

Constrained generation makes models somewhat less intelligent. Although it shouldn't be an issue in thinking mode, since it can prepare an unconstrained response and then fix it up.
