Your schema asks.
Does the API enforce it?

Find constraints documented as ignored by Gemini structured outputs. See the exact paths, then check what your application still needs to validate.

Your constraint report

A static review of documented behavior. This does not call or emulate Gemini.

Choose an example or paste a schema.

Reports include your field paths. Review them before sharing.

01Inspect the specific job

This profile reviews the schema for a final JSON response. Function calling and SDK request conversion are separate checks.

02Keep unknowns visible

A keyword outside this profile is marked not assessed. No finding is a compatibility certificate.

03Keep your own validation

Check values against your original schema in your application. Try the maxLength example to see the difference.
