What problem does it solve? Building or modifying PowerPoint decks programmatically is error-prone: text overflows shapes, fonts drift between masters, charts pick wrong types, and shell quoting corrupts values. This Skill provides a complete, disciplined workflow for producing presentation-quality .pptx files through the officecli CLI, with explicit design rules and QA gates. ## Core Features & Use Cases - Deck creation and editing: Create slides, shapes, charts, tables, pictures, connectors, animations, speaker notes, and comments via officecli commands with XPath-style element addressing. - Design enforcement: Built-in typography hierarchy, color palettes, font pairings, grid math, chart-choice tables, and layout patterns ensure every slide meets a visual delivery floor. - Reading and QA: Inspect decks with outline, annotated, text, and HTML views, query elements with CSS-like selectors, and validate overflow, contrast, and placeholder issues before delivery. - Use Case: Ask for a quarterly business review deck and receive a validated .pptx with a branded cover, data slides with charts and commentary cards, speaker notes on every slide, and zero overflow or contrast defects. ## Quick Start Create a five-slide pitch deck named pitch.pptx with a dark cover slide, one chart slide, and speaker notes on every content slide.
