pptx-author
Use this skill when running headless (headless Codex mode) and you need to deliver a PowerPoint deck as a file artifact rather than editing a live document via available presentation tools.
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")
slide = prs.slides.add_slide(prs.slide_layouts[5])
slide.shapes.title.text = "Valuation Summary"
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 available presentation tools 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.
