Produce a .pptx file on disk (headless) instead of driving a live PowerPoint document — for managed-agent sessions with no open Office app.
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)
- One idea per slide. Title states the takeaway; body supports it.
- Every number traces to the model. If a figure comes from
./out/model.xlsx, footnote the sheet and cell.
