When you're running Claude in headless mode without an open PowerPoint instance, this skill lets you generate complete decks as file artifacts instead. It wraps python-pptx into a simple contract: write a Python script that outputs to ./out/, optionally pull from a firm template, and return the path. The conventions mirror the live pitch-deck skill (one idea per slide, every number sourced, charts as embedded PNGs when precision matters), so you get the same structured output whether you're driving Office interactively or rendering files in a managed agent session. It's the fallback for when mcp__office__powerpoint_* tools aren't available, which makes it clean separation of concerns rather than yet another way to do the same thing.

pptx-author

Use this skill when running headless (managed-agent / CMA mode) and you need to deliver a PowerPoint deck as a file artifact rather than editing a live document via mcp__office__powerpoint_*.

Output contract

  • Write to ./out/<name>.pptx. Create ./out/ if it does not exist.
  • Return the relative path in your final message so the orchestration layer can collect it.

How to build the deck

Write a short Python script and run it with Bash. Use python-pptx:

from pptx import Presentation
from pptx.util import Inches, Pt

prs = Presentation("./templates/firm-template.pptx")  # if a template is provided
# or: prs = Presentation()

slide = prs.slides.add_slide(prs.slide_layouts[5])    # title-only
slide.shapes.title.text = "Valuation Summary"
# ... add tables / charts / text boxes ...

prs.save("./out/pitch-<target>.pptx")

Conventions (mirror the live-Office pitch-deck skill)
