SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually building PowerPoint decks for finance and business use cases often leads to errors where figures drift from their source models, and the process is time-consuming without programmatic automation. This Skill solves that by enabling headless, code-driven deck generation where every number is directly bound to a validated source workbook.

Core Features & Use Cases

  • Headless Deck Generation: Build .pptx files without a live PowerPoint application session, ideal for automated workflows.
  • Model-Backed Number Binding: Automatically pull financial figures from source Excel workbooks so deck values never drift from their source data.
  • Branded Template Support: Inherit firm-standard colors, fonts, and layouts by loading a pre-mounted firm PowerPoint template.
  • Use Case: Investment teams use this Skill to generate pitch decks, internal investment committee memos, and earnings notes where every financial metric must be verifiable and traceable to a validated model.

Quick Start

Use the pptx-author skill to generate a pitch deck for Project Aurora with all valuation figures pulled directly from the attached model.xlsx workbook and saved to the ./out directory.
