The facts

Its description

Produce a .pptx file on disk (headless) instead of driving a live PowerPoint document — for managed-agent sessions with no open Office app.

The description the agent reads to decide when to use it.

From its settingsline 3

When it starts

The agent picks this when it is running headless (managed-agent / CMA mode) with no open Office app and needs to deliver a PowerPoint deck as a file artifact on disk rather than editing a live document through the Office MCP tools.

Things a person might say (the model's guesses)

  • “Build me a valuation summary deck and save it as a .pptx file — I don't have PowerPoint open.”
  • “We're in a headless session, so just write the deck out to ./out/ as a pptx.”
  • “Put together a pitch deck file for the target company; there's no live Office app available here.”

10## Output contract
12- Write to `./out/<name>.pptx`. Create `./out/` if it does not exist.
13- Return the relative path in your final message so the orchestration layer can collect it.

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.

15## How to build the deck
17Write a short Python script and run it with Bash. Use `python-pptx`:
19```python
20from pptx import Presentation
21from pptx.util import Inches, Pt
23prs = Presentation("./templates/firm-template.pptx") # if a template is provided
24# or: prs = Presentation()
26slide = prs.slides.add_slide(prs.slide_layouts[5]) # title-only
27slide.shapes.title.text = "Valuation Summary"
28# ... add tables / charts / text boxes ...
30prs.save("./out/pitch-<target>.pptx")
31```

# 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")

33## Conventions (mirror the live-Office `pitch-deck` skill)
35- **One idea per slide.** Title states the takeaway; body supports it.
36- **Every number traces to the model.** If a figure comes from `./out/model.xlsx`, footnote the sheet and cell.
37- **Use the firm template** when one is mounted at `./templates/`; otherwise default layouts.
38- **Charts**: prefer embedding a PNG rendered from the model over native pptx charts when fidelity matters.
39- **No external sends.** This skill writes a file; it never emails or uploads.

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.

41## When NOT to use
43If `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.
