Weekly Performance Slide Deck

Generate a week-over-week creative performance analysis as a presentation-ready slide deck. The deck tells a story — it's not a data dump.

Phase 0: Orient

1. Acknowledge: "Building your week-over-week creative performance deck."
2. Ask format: "HTML slide deck, Notion, or Slack? Anything specific you want highlighted?"
3. Connected workflow: After the deck, you can dive into specific ads (/analyze-ad), find iterations on fatiguing creatives (/find-iterations), or generate concepts to fill gaps (/create-concepts).

If the user already specified the format, skip the question and build.
