What problem does it solve? Building or extending integrated financial models often results in hardcoded outputs, broken formulas, unexplained plugs, and workbooks that no other analyst can audit or update. This Skill enforces a disciplined architecture so models remain traceable, formula-consistent, and verifiable from sources through outputs. ## Core Features & Use Cases - Three-Statement Model Construction: Links Income Statement, Balance Sheet, and Cash Flow with roll-forward schedules for debt, equity, working capital, capex, and depreciation. - Existing Workbook Extension: Inspects formulas, named ranges, external links, and hidden structures before making minimal, non-destructive changes such as extending forecast periods or adding downside scenarios. - Built-in Model Checks: Validates A=L+E balance, cash flow tie-outs, roll-forwards, formula errors, and unexplained plugs, reporting a clear MODEL STATUS: PASS/FAIL. - Use Case: A user provides historical financial statements and asks for a five-year three-statement model with base and downside scenarios; the Skill builds driver-based schedules, scenario tables, a checks sheet, and a version log. ## Quick Start Ask the assistant to turn your historical financial statements into a five-year three-statement model with scenario and sensitivity schedules and a checks sheet.
