Requirements for Outputs

Design guidance: For styled spreadsheets (dashboard reports, branded workbooks), see skills/design-foundations/SKILL.md for the default accent color and chart colors. Reserve color for emphasis — most cells should use default black text on white. Use the accent color sparingly (header rows, key totals). Financial model color conventions below are industry-standard overrides and take priority.

User-Facing Delivery

When reporting back to the user:

• describe what the spreadsheet does, not which library created it
• mention the structure, formulas, sheets, charts, and outputs in plain language
• say that calculations update automatically when inputs change when that is true
• do not narrate internal implementation details unless the user explicitly asks

All Excel files

Professional Font

• Use a consistent, professional font (e.g., Calibri, Arial) for all deliverables unless otherwise instructed by the user
