- ListEvaluatorsResponse
  - `evaluators` Evaluator[], required — A list of evaluators
    - `id` string, required — The unique identifier for the evaluator
    - `name` string, required — The name of the evaluator
    - `description` string, nullable — The description of the evaluator
    - `type` 'TEMPLATE' | 'CODE' | 'HARNESS' | 'REMOTE', required — The evaluator type: - `TEMPLATE` — LLM-based evaluator. - `CODE` — managed built-in evaluators or custom Python code (both are subtypes of `CODE`, discriminated by the nested `CodeConfig.type` = `MANAGED` | `CUSTOM`). - `HARNESS` — test harness evaluator. - `REMOTE` — remote evaluator. Applies to both the parent `Evaluator.type` field and every version's `type` discriminator — a version's `type` must always match its parent evaluator's `type`.
    - `space_id` string, required — The unique identifier for the space the evaluator belongs to
    - `created_at` string, date-time, required — When the evaluator was created
    - `updated_at` string, date-time, required — When the evaluator was last updated
    - `created_by_user_id` string, nullable, required — The unique identifier for the user who created the evaluator
  - `pagination` PaginationMetadata, required — Cursor-based pagination metadata. Use `next_cursor` in the subsequent request's `cursor` query parameter.
    - `next_cursor` string — Opaque cursor for fetching the next page. Treat as an unreadable token. Present when `has_more` is true; omitted when `has_more` is false.
    - `has_more` boolean, required — True if another page of results is available.
