What problem does it solve? Rebuilding promo campaign post-mortem analyses from scratch each quarter leads to inconsistent numbers and repeated mistakes. This Skill computes the standard recap cuts (cash, redemptions, NPL/Non-NPL, region, channel, page-level attribution) the same way every time, with documented corrections and a reusable campaign registry. ## Core Features & Use Cases - Standardized recap cuts: Produces cash, redemptions, payer-type, regional, traffic-source, and page-level attribution breakdowns for B2C promo campaigns via saved Databricks SQL queries. - Extensible campaign registry: New campaigns are added to one reference file with confirmed promotion_ids and date windows, without touching the methodology. - Documented corrections: Standing fixes (payment_order filtering, C+ Annual SKU dual detection, late-arrival trims, timezone padding) prevent known undercounting and inflation bugs. - Use Case: A stakeholder asks for a Q3 tentpole post-mortem broken out by region and channel; the Skill reuses saved query patterns and the campaign registry to produce consistent, cross-checked numbers. ## Quick Start Ask the assistant to build a post-mortem recap for a named promo campaign broken out by region and traffic channel using the Databricks MCP read-only SQL tool.
