This builds full DCF valuation models in Excel with live formulas, not hardcoded numbers. It pulls financial data from SEC filings or user inputs, projects cash flows with proper WACC calculations, and generates sensitivity tables that actually recalculate across different assumption combinations. The skill is opinionated about doing this right: every projection must be a formula, you verify each section with the user before moving forward, and sensitivity tables use odd dimensions so the center cell shows your base case. It handles both Office.js environments and standalone Python/openpyxl generation. Honestly, the thoroughness here is what you'd want if you're building models for actual investment decisions rather than quick back-of-napkin estimates.
