Analyzes content performance data — CSV exports, pasted metrics, or analytics screenshots — and returns what worked, what didn't, and prioritized next actions tied to specific numbers. USE WHEN analytics, performance, metrics, how did my video do, why did this flop, engagement rate, views dropped, what's working, review my numbers, content audit, retention graph. NOT FOR planning upcoming content (use content-plan) or pre-publication SEO (use seo-optimize).
