Skill instructions

excel-author Produce an .xlsx file on disk using openpyxl. Follow the banker-grade conventions below so the model is auditable, flexible, and reviewable by someone other than the person who built it.

Create ./out/ if it does not exist. - Return the relative path in your final message so downstream tools can pick it up. - One logical model per file. Do not append to an existing workbook unless explicitly asked. Setup bash pip install "openpyxl=3.0" Core conventions (non-negotiable) Blue / black / green cell color - Blue (Font(color="0000FF")) — hardcoded input a human entered. Revenue drivers, WACC inputs, terminal growth, market data. - Black (default) — formula. Every derived cell is a live Excel formula. - Green (Font(color="006
