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.
Use the firm template when one is mounted at ./templates/; otherwise default layouts.
Charts: prefer embedding a PNG rendered from the model over native pptx charts when fidelity matters.
No external sends. This skill writes a file; it never emails or uploads.

When NOT to use

If mcp__office__powerpoint_* tools are available (Cowork plugin mode), use those instead — they drive the user's live document with review checkpoints. This skill is the file-producing fallback for headless runs.
