What problem does it solve? Building an auditable financial model in Excel requires strict discipline: assumptions separated from calculations, statements that balance every period, and valuation cells with correct cached values. This Skill encodes that discipline as executable recipes and delivery gates so the output is a decision-grade .xlsx rather than a fragile spreadsheet. ## Core Features & Use Cases - Three model recipes: Runnable skeletons for 3-statement models (P&L + Balance Sheet + Cash Flow), DCF valuations (WACC, NPV, terminal value, sensitivity grid), and LBO models (Sources & Uses, multi-tranche debt schedules, cash sweep, MOIC/IRR returns). - Three-zone architecture with audits: Enforces Inputs / Calc / Outputs sheet separation, CFO 4-color code, named ranges, and zero-hardcode rules verified by executable zone audits. - Delivery gates and cache discipline: Balance checks, cash reconciliation, cache-refresh passes, and sensitivity/scenario protocols that refuse delivery on imbalanced statements. - Use Case: Ask for a DCF valuation of a company and receive a single .xlsx with an Assumptions sheet, 10-year FCF build, WACC panel, equity bridge, and a 5x5 WACC-by-growth sensitivity grid. ## Quick Start Ask the agent to build a 3-statement financial model in Excel with revenue growth, margin, and tax assumptions for the next four years.
