# workflowCapabilities

> Returns which blocks (condition/action/wait steps) are available for a workflow of the given
trigger type. The builder UI sources its palette from this so the allow-list lives in the
backend, not hardcoded in the UI. E.g. SCHEDULE workflows have no thread, so they allow no
conditions/waits and only a restricted set of action types.
