Shared schema definitions

Source-generated field definitions, nested types, defaults, required flags, and constraints for this contract.

Public betaAPI v1 · 1.3.0Last verified
On this page

A dash means no default is declared, not a null value. A field can be optional in JSON Schema but conditionally required by the documented workflow. Model-specific options still require live capability discovery.
