What problem does it solve?

Building complex, consistent Excel financial models manually is time-consuming and prone to human error, with mistakes in formula entry, style application, or sheet wiring leading to critical inaccuracies in high-stakes financial analysis. This skill eliminates that risk by fully automating the Phase 4 model build process to strictly follow a pre-approved design specification.

Core Features & Use Cases

• End-to-end build automation: Executes the full 23-step Phase 4 workflow via pywin32 COM, creating sheets, applying cell styles, entering formulas, setting named ranges, adding data validation, conditional formatting, and print setup exactly per the Phase 3 design spec.
• Built-in consistency guardrails: Enforces critical modeling rules like uniform R1C1 formulas across time periods, linked labels instead of retyped text, and style-before-content ordering to eliminate common modeling errors.
• Use case: Financial analysts building 3-statement models, project finance models, M&A models, or budget forecasts can use this skill to turn a completed design document into a production-ready, verified Excel workbook in minutes instead of hours of manual work.

Quick Start

Use the fm-4-build skill to construct a production-ready Excel financial model from your Phase 3 design.md and plan.md files, saving the final workbook to your specified output path.
