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.

Hermes Profile Notes

This skill was packaged from pi-financial-services source path plugins/vertical-plugins/financial-analysis/skills/pptx-author for the Hermes financial-services profile. Use institutional data connectors first when available, cite sources, and stage outputs for qualified human review.

Common Pitfalls

1. Do not present drafts as investment, legal, tax, or accounting advice.
2. Do not use web search as the primary source when an institutional MCP/data connector is available.
3. Do not execute transactions, contact clients, post to a ledger, or approve onboarding. Stage outputs for review.

Verification Checklist

• Inputs, assumptions, dates, and currencies are explicit.
• Numbers tie across tables, models, decks, and memos.
• Sources are cited and institutional data is preferred where available.
• Output is labeled draft / for human review where appropriate.
