pptx is a skill for Claude Code, Codex from shahidshabbir-se/my-pi-setup. It costs 217 tokens per session (7,236 once invoked), scanned A, original, MIT.

A presentation-handling skill for creating, reading, editing, and converting PowerPoint files such as .pptx and .potx.

In plain words
What is it for?
Use it to build slide decks, modify existing presentations or templates, and extract text or visual information from slides.
Why use it?
It gives a defined way to work with slide content and layouts rather than editing presentation files blindly.

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 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 yesterday.

The scan reads SKILL.md. This mod also ships 16 executable files (scripts/__init__.py, scripts/add_slide.py, scripts/apply_theme.js, …), 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.

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 — and build it as a structured deck unless the user asks for a quick throwaway
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/apply_theme.js Node module: const { applyTheme } = require("<this skill's directory>/scripts/apply_theme.js"). await applyTheme("deck.pptx", THEME) after pres.writeFile() writes THEME's colors and name (escaped for XML) into the deck's theme, for structured decks. Also a CLI: node scripts/apply_theme.js deck.pptx theme.json
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

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.
