A set of specialist marketing workflows for diagnosing campaign performance, evaluating spend risk and pacing, comparing budget allocations, breaking down creative patterns, planning creative refreshes, simulating scenarios, auditing attribution and incrementality, learning from campaign history, and checking recommendation quality. It works from data supplied by the user or data available through authorized host tools. It does not change live campaigns or budgets unless the current host separately exposes a compatible write-capable app and the user explicitly authorizes that action.
