A tool for creating, reading, editing, and converting PowerPoint presentations (.pptx), including slide content and templates.

Use it to create briefings and pitch decks, modify existing presentations, extract slide text, and convert presentations to PDFs or images.

It avoids manually changing presentation files or extracting their contents when slides need repeatable edits or checks.

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	$0.00188	$0.04158
Opus 5	$0.00094	$0.02079
Sonnet 5	$0.00038	$0.00832
Haiku 4.5	$0.00019	$0.00416

Security

Grade B, and why

pptx scanned grade B with 1 finding 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 16 executable files (scripts/__init__.py, scripts/add_slide.py, scripts/clean.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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

L0: One-Sentence Summary

Create, edit, and process PowerPoint presentations (.pptx), with support for template editing and creation from scratch.

L1: Overview and Use Cases

Capability Description

pptx is a Procedural Skill providing full PowerPoint presentation processing capabilities. It supports creating presentations from scratch via pptxgenjs (Node.js), editing existing templates by unpacking XML, plus content extraction and visual quality checks.

Use Cases

The user needs to create a new presentation (briefing materials, pitch deck, etc.)
The user needs to edit or modify an existing .pptx file
The user needs to extract text content from a .pptx file
The user needs to convert a presentation to PDF or images

L2: Detailed Specification

Script Path Rule (mandatory)

The Python scripts bundled with this skill live inside the skill installation directory. You MUST use full paths when invoking them — never use bare relative paths.

The skill directory is provided by the <skill-dir> tag in the context. Prefix all scripts/ commands accordingly:

python "<skill-dir>/scripts/office/unpack.py" presentation.pptx unpacked/
python "<skill-dir>/scripts/office/pack.py" unpacked/ output.pptx
python "<skill-dir>/scripts/office/soffice.py" --headless --convert-to pdf output.pptx
python "<skill-dir>/scripts/thumbnail.py" presentation.pptx

NEVER run python scripts/office/unpack.py directly — that relative path does not exist in the user's working directory.

Prerequisites

Python 3 (required — needed when reading and editing existing PPTX)

Before running any Python script, check that Python is available:

python3 --version 2>/dev/null || python --version 2>/dev/null

If the command fails (Python is not available), you must stop and tell the user to install Python 3:

macOS: brew install python3, or download from https://www.python.org/downloads/
Windows: winget install Python.Python.3, or download from python.org (check "Add Python to PATH" during installation)
Linux (Debian/Ubuntu): sudo apt install python3 python3-pip
Linux (Fedora/RHEL): sudo dnf install python3 python3-pip

What ships with it

58 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.
