Description
The root schema must not use enum
Provider Evidence
| Profile | Status | Source | Basis |
|---|---|---|---|
| openai.so.2026-04-30 | inferred | OpenAI root object | The root schema is documented as an object; a root enum is therefore outside the subset. |
Rationale
openai.so.2026-04-30 requires a plain object root and rejects enum at the top level.
Bad Example
{ "type": "string", "enum": ["yes", "no"] }
Good Example
{ "type": "object", "properties": { "answer": { "type": "string", "enum": ["yes", "no"] } }, "required": ["answer"], "additionalProperties": false }
