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.
