Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is (cd unpacked && rm -f ../out.pptx && zip -Xr ../out.pptx .) # zip from INSIDE the dir; rm first or deleted parts survive.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

Security

Grade B, and why

powerpoint 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 9d ago.

The scan reads SKILL.md. This mod also ships 15 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.

How it starts

The opening of the file, as written. The whole thing — 257 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Powerpoint Skill

Create, read, and edit PowerPoint decks — from-scratch generation with pptxgenjs, template-based editing via direct XML manipulation, speaker notes, charts, and design QA. A .pptx is a ZIP archive of XML files.

When to Use

Use this skill any time a .pptx or .potx file is involved in any way — as input, output, or both: creating slide decks, pitch decks, or presentations; reading or extracting text from any .pptx; editing existing presentations; combining or splitting slide files; working with templates (.potx), layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx/.potx filename.

Prerequisites

npm ls pptxgenjs --depth=0 2>/dev/null | grep -q pptxgenjs || npm install pptxgenjs
pip install "markitdown[pptx]" Pillow defusedxml lxml
which soffice || sudo apt install -y libreoffice     # rendering/QA
which pdftoppm || sudo apt install -y poppler-utils  # PDF → images

macOS: brew install libreoffice poppler. Icons in generated decks additionally use react-icons react react-dom sharp (npm).

Quick Reference

Task Approach
Create a new deck Write a pptxgenjs script — see gotchas below
Edit an existing deck, or build from a template unzip → edit ppt/slides/slideN.xml → zip
Read content markitdown deck.pptx (one block per slide under <!-- Slide number: N --> markers); visual grid: python scripts/thumbnail.py deck.pptx

Scripts

Paths are relative to this skill's directory. Everything else is plain Python, node, or shell.

Script What it does
scripts/thumbnail.py deck.pptx [prefix] Labeled grid of every slide, for picking template layouts. .pptx only. Pass prefix — it defaults to thumbnails, which overwrites the grids of any other deck done in the same directory
scripts/add_slide.py unpacked/ slide2.xml [--after slideN.xml] Duplicate a slide (or a slideLayoutN.xml) with all the package bookkeeping. Also takes a .pptx directly with -o out.pptx
scripts/clean.py unpacked/ Delete slides, media, and rels no longer referenced. Run after <p:sldIdLst> is final
scripts/office/validate.py deck.pptx [--original src.pptx] Schema, relationship, content-type, chart and slide checks; each failure names its fix. Pass --original for any template-derived deck — it baselines the schema checks against the template, so the template's own XSD errors don't read as yours
scripts/office/soffice.py --headless --convert-to pdf deck.pptx LibreOffice wrapper — bare soffice hangs in sandboxed environments

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.
