Description

The root schema must not use anyOf

Rationale

openai.so.2026-04-30 requires a plain object root; anyOf is only valid below the root.

Bad Example

{ "type": "object", "anyOf": [{ "type": "object" }] }

Good Example

{ "type": "object", "properties": { "value": { "anyOf": [{ "type": "string" }, { "type": "number" }] } }, "required": ["value"], "additionalProperties": false }
