Headless PowerPoint generation for when you're running Claude in managed-agent mode and need a deck written to disk instead of driving a live Office document. Wraps python-pptx in a simple contract: drop the file in ./out/ and return the path. Mirrors the same one-idea-per-slide conventions as the live pitch-deck skill, supports firm templates when mounted, and expects every number to trace back to your model with proper footnotes. The source is clear about when not to use it: if the mcp__office__powerpoint_* tools are available, those are better because they give the user review checkpoints in the live document. This is the fallback for CMA sessions.

Files

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")
