Hand this action's work to another agent, with the acceptance criterion written first.

acceptance_criterion and expected_result are REQUIRED and are stored before anyone executes, so the judgement cannot be invented afterwards. deadline_at must be in the future. Only an action that is still pending and not yet executed can be delegated, and only one delegation can be active per action; the delegation changes NONE of the action's four status columns. required_capability, when given, only filters who may take it.
