What problem does it solve? Building a Configure-Price-Quote calculator by hand from a commercial playbook is error-prone: prices drift from the published rate card, margin formulas get misapplied, and volume discount logic is inconsistent. This Skill derives a CPQ calculator spec directly from the offering's COMMERCIAL_PLAYBOOK.md and LEAN_BUSINESS_CASE.md so every price traces back to the approved rate card. ## Core Features & Use Cases - Rate Card Extraction: Parses published rates, volume discount schedules, and bundle pricing logic from COMMERCIAL_PLAYBOOK.md sections. - Three-Sheet Calculator Design: Produces Input, Calculator, and Quote Output sheet layouts with Excel formulas, validation rules, and conditional formatting. - Optional .xlsx Generation: Generates the actual Excel file via openpyxl when available, otherwise delivers a markdown specification. - QA Gate: Runs a financial QA validation pass with a maximum of two rework cycles before escalating. - Use Case: Given an offering folder like OFFER-001, produce a CPQ_CALCULATOR.xlsx whose prices, margins, and discounts exactly match the commercial playbook, ready for IOF/COF quote generation. ## Quick Start Run the cpq skill with argument 001 to generate the CPQ calculator spec for offering OFFER-001 from its commercial playbook.
