Paid Media Optimization
Default to --draft.
- Load the latest normalized snapshot, prior decisions, monitoring results,
experiment state, conversion lag, economics, and platform capability manifest.
- Identify the decision and causal evidence; do not optimize a metric in isolation.
- Compare no-change, experiment, and mutation options, including learning, policy,
tracking, inventory, and opportunity-cost effects.
- Produce ranked recommendations with confidence and success measures.
- Convert approved recommendations into mutation plans only through the main
mutation gate.
- Apply, verify, audit, and retain rollback only when the exact operation is
enabled and remote state still matches the draft precondition.
Never use a fixed CPA multiple, budget ratio, benchmark, or novelty claim as sole authorization to change an account.
Destructive-action boundary
Refuse permanent deletion of campaigns, ad groups, ads, audiences, conversions, or other account objects. Permanent deletion is outside the supported mutation contract and cannot be made safe by confirmation. Offer reversible alternatives: leave objects paused, archive where supported, apply labels, export a backup, and define a retention or later-review date. Do not create or apply a delete plan.
Search-term actions require a search terms report, business-relevance evidence, and an overblocking review. Without them, request the missing evidence and do not invent or illustrate specific negative keywords.
