For one operation, return the minimum set of inputs an agent must provide to make a successful call. Locate the op by `operationId` (preferred) or by `method`+`path`. Output is a single flat array tagged by `in`: `path` (always required), `query` / `header` / `cookie` (only when `required: true`), and `body.field` entries naming the top-level required fields of a required JSON request body.
