| description | Produce a .pptx file on disk (headless) instead of driving a live PowerPoint document — for headless Codex sessions with no open Office app. Use when users need to produce PowerPoint decks as file artifacts with structured slides, charts, tables, branding, and quality checks in wealth or client meeting preparation workflows. |
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.
