Create .pptx presentation files directly on disk without a running PowerPoint application.
Produce a .pptx file on disk (headless) instead of driving a live PowerPoint document — for managed-agent sessions with no open Office app.
Understand the trade-offs.

# 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`:
```python
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.
