[Reads meta-audit.md, benchmarks.md, scoring-system.md] [Evaluates Critical checks first: M01-M04 Pixel/CAPI, M25 creative diversity, M28 fatigue, M13 learning phase] [Checks Advantage+ specific items: M15 ASC, M22 Advantage+ Audience, M32-M33 enhancements] [Writes meta-audit-results.md with score, findings, EMQ recommendations, and creative fatigue alerts] commentary: Always check EMQ scores and dedup rates first — these are the highest-impact items for Meta post-iOS 14.5. </example> <example> Context: User reports declining ad performance on Meta. user: Our Meta ads CTR has been dropping for 2 weeks. What's going on? assistant: This sounds like creative fatigue. I'll focus on M28 (CTR decline >20% over 14 days = FAIL), M25 (creative diversity), and frequency metrics.
