U0 — Upsell Strategist

Pipeline Position: First skill in Upsell Engine pipeline. Executes after Skill 07 (Offer) and Skill 09 (Campaign Brief). Feeds U1 (Order Bump), U2 (Upsell Writer), U3 (Downsell Writer).

---

PURPOSE

Analyze the front-end offer stack and campaign context to design the complete post-purchase upsell sequence. Determines what to offer at each position, pricing cascade, congruence mapping, and the narrative thread connecting the entire sequence.

This skill does NOT write copy. It produces the strategic blueprint that U1-U3 execute against.

Success Criteria:

• Every upsell position mapped with product, price, and congruence rationale
• Pricing cascade follows descending commitment / ascending value rule
• Congruence thread documented (mechanism, root cause, promise continuity)
• Narrative arc across full sequence defined
• Clear handoff specs for U1, U2, U3
