## Response `200`

A page of custom behaviors.

- CustomBehaviorList
  - `results` CustomBehaviorWithTags[], required: Custom behaviors, most recently updated first.
    - `id` string, required: Custom behavior ID. It is also the behavior's key in analytics, filters and span verdicts.
    - `name` string, nullable, required: Display name. Optional and not unique; behaviors are identified by `id`.
    - `description` string, required: The plain-language definition span-01 scores each span against. Say what counts and what doesn't. At least 3 characters after trimming.
    - `polarity` 'negative' | 'positive' | 'neutral', required: Whether the behavior firing is good or bad: `negative` (an Issue), `positive` (a Win) or `neutral` (Info). Display metadata only; it does not change how spans are scored.
    - `created_at` string, date-time, required
    - `updated_at` string, date-time, required
    - `tags` BehaviorTag[], required: Tags on the behavior.

      - `updated_at` string, date-time, required
  - `count` integer, required: Number of behaviors on this page (not the total).

  - `current_filters` object: Always empty for this endpoint.
