pptx + excal Deck Builder

Build template-bound, validated PowerPoint decks with professional diagrams. This skill combines two CLI tools (pptx for slide generation, excal for diagrams) with consulting-grade presentation principles.

When to read the reference files

• references/pptx-workflow.md — Read when you need the full pptx CLI command reference, manifest structure, placeholder details, deck spec format, error codes, or image-handling workarounds.
• references/excal-diagrams.md — Read when you need to create Excalidraw diagrams, render them to PNG, or understand the scene JSON format.
• references/mckinsey-style.md — Read when the user asks for consulting-style, executive, strategy, or McKinsey-style presentations. Also read when you need guidance on action titles, storyline structure, slide archetypes, or the Pyramid Principle.
