PPTX Builder
Official skill for generating and editing slide decks that keep their master layout.
Use it for
Producing a first draft deck from an existing template instead of starting from a blank file
Skip it if
Design-heavy decks where every slide is bespoke; the skill respects layout, it cannot invent taste
What it is
An official presentation skill that builds slides inside an existing master, so fonts and placeholders stay consistent. It can add slides, fill placeholders, insert tables, and duplicate layouts. Treat the output as a structured draft: correct in hierarchy, still needing a human pass for emphasis.
Install
Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.

Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
