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.

Good fit Use it to build a new presentation, update an existing deck, work from a template, or inspect slide content and layout.

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 A, and why

pptx 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 14d 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.

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.

Origin

This is a copy

100% identical to pptx — 39 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PPTX creation, editing, and analysis

If this session offers a dedicated slide-deck artifact type or a separate slides skill, and the user has neither asked for a PowerPoint/.pptx file nor supplied a .pptx/.potx file to edit, fill in, or convert, build the deck with that type or skill instead. A .pptx/.potx file given only as source material or as an example for a new deck ("make another deck like this one") does not count as supplied: read it with this skill, then build the new deck with that type or skill. This skill remains the right tool for producing .pptx files and for reading, editing, templating, or converting existing .pptx/.potx files.

A .pptx is a ZIP archive of XML files. Choose your approach by task:

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 this sandbox

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.
