A tool for creating, reading, and editing PowerPoint presentation files (.pptx) with Python. It can work with slide text, notes, tables, charts, images, templates, and slide order.

Use it to build pitch decks and reports, inspect shared presentations, update branded templates, change chart data, or render slides for review.

It removes the need to edit presentation files manually or have PowerPoint installed for many common deck changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00018	$0.02850
Opus 5	$0.00009	$0.01425
Sonnet 5	$0.00004	$0.00570
Haiku 4.5	$0.00002	$0.00285

Security

Grade A, and why

powerpoint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/pptx_create.py, scripts/pptx_edit.py, scripts/pptx_from_template.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Powerpoint Skill

Create, inspect, and edit PowerPoint (.pptx) presentations using the python-pptx library. Five helper scripts cover deck creation from a JSON spec, structured read-back, in-place edits, template-driven brand decks, and slide rendering — all offline, no PowerPoint installation required.

When to Use

The user asks to build a slide deck, report presentation, or pitch deck.
You need to extract text, notes, tables, chart data, or images from a .pptx someone shared.
You need to update an existing deck: replace text, refresh or patch chart data, swap a logo, duplicate/remove/reorder slides, set backgrounds, footers, hyperlinks, or speaker notes.
You must produce an on-brand deck from a company .pptx template.
Do NOT use this for .ppt (legacy binary) files — convert them first with soffice --convert-to pptx old.ppt if LibreOffice is available.

Prerequisites

Python 3.10+ with python-pptx installed (pip install python-pptx).
Optional: LibreOffice (soffice) plus poppler (pdftoppm or pdftocairo) for rendering slides to PNGs and for PDF export. pptx_render.py detects both with shutil.which and degrades gracefully (reports {"rendered": false, "missing": [...]}, exit 0) when absent — all create/read/edit operations work without them.
Check availability via terminal: python -c "import pptx; print(pptx.__version__)" and which soffice pdftoppm.

How to Run

All scripts live in scripts/, take --help, print JSON to stdout, and exit non-zero on failure. Run them with terminal:

python scripts/pptx_create.py deck.json out.pptx
python scripts/pptx_read.py deck.pptx --outline      # full JSON outline
python scripts/pptx_read.py deck.pptx --notes        # speaker notes
python scripts/pptx_read.py deck.pptx --images ./img # export pictures
python scripts/pptx_edit.py deck.pptx --replace-text "Old Corp" "New Corp"
python scripts/pptx_edit.py deck.pptx --chart-data update.json
python scripts/pptx_edit.py deck.pptx --duplicate-slide 2
python scripts/pptx_edit.py deck.pptx --remove-slide 3 --move-slide 2 0
python scripts/pptx_from_template.py brand.pptx out.pptx --values vals.json
python scripts/pptx_render.py deck.pptx --outdir ./render  # slide PNGs

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
