pptx is agent-read markdown (skill) from ginlix-ai/langalpha: PowerPoint decks built with pptxgenjs and native charts, existing decks edited in place with python-pptx, then rendered to images and audited for overflow, overlap, bounds and typography before delivery.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# PPTX
Build or edit a PowerPoint deck and write it into the task directory (e.g. `acme_q4/acme_q4_review.pptx`). Someone will stand in front of it, or forward it to a colleague who will. That is what the format is for: **a deck is a sequence of single claims, each sized to be read from the back of a room.** A slide that needs a paragraph is not a slide, it is a page, and it belongs in a report.
This is the right output when the deck itself is the deliverable: an investment committee pack, a diligence readout, a board update, an earnings walkthrough. It is the wrong output for anything the reader will study alone at their own pace (that is `html-report`) and for anything they will change numbers in (that is `xlsx`).
> **User preferences override these defaults.** A house template, a brand palette, a required title slide, a fixed section order: those outrank every rule here. If the user hands you a deck to work in, work in it and match what is already there. The rules below are for when nothing has been specified.

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
