Pptx Design Agent

pptx-design

A Claude Code skill for creating and editing professional PowerPoint presentations on macOS with premium design quality. macOS 上的专业 PowerPoint 演示文稿创建与编辑技能，具备高品质视觉设计。

Architecture

**Dual-engine approach** for macOS PowerPoint automation:

Engine	Technology	Role
python-pptx	python-pptx + lxml (file-based)	Bulk creation, gradients, corner radius, letter spacing, images, charts, tables
AppleScript IPC	osascript (live editing)	Text edits, font properties, positions, fills, z-order, visibility, rotation, shadows, speaker notes, slide management

**Golden Rule:** Build with python-pptx, tweak with AppleScript. For edit-only tasks on an open presentation, use AppleScript alone (no python-pptx, no file reload).

**No stale display issue:** Unlike the xlsx skill, python-pptx writes files without PowerPoint open, so AppleScript's `open POSIX file` always loads a fresh copy from disk.
