What it does

Shadow offset must be ≥ 0 — a negative offset corrupts the file. To cast a shadow upward, use angle: 270 with a positive offset.
letterSpacing is silently ignored — the real option is charSpacing.
One new pptxgen() per output file — never reuse an instance.
rectRadius only works on ROUNDEDRECTANGLE, not RECTANGLE.
Gradient fills aren't supported — use a gradient image as the background instead.
Text boxes have built-in internal padding — set margin: 0 whenever text must align with a shape, line, or icon at the same x.
Speaker notes go in slide.addNotes("...") (plain text, once per slide), never in a text box on the slide.

Requirements & configuration

Text with leading or trailing spaces needs xml:space="preserve" on its <a:t>.
Every slide needs a visual element — image, chart, icon, or shape. Text-only slides are forgettable.
Don't skimp on size contrast — titles need 36pt+ to stand out from 14-16pt body
Don't use low-contrast elements — icons AND text need strong contrast against the background; avoid light text on light backgrounds or dark text on dark backgrounds

pptx FAQ

What does the pptx skill do?

Use this skill any time a .pptx or .potx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx or .potx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates (.potx), layouts, speaker notes, or comments. Trigger whenever the user mentions \"deck,\" \"slides,\" \"presentation,\" or references a .pptx or .potx filename, regardless of what they plan to do with the content afterward. If a .pptx or .potx file needs to be opened, created, or touched, use this skill. Shadow offset must be ≥ 0 — a negative offset corrupts the file. To cast a shadow upward, use angle: 270 with a positive offset. letterSpacing is silently ignored — the real option is charSpacing.
