Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by bluzir on GitHub. Read the source before you install it.

Installation

Install the Export Pptx AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/bluzir/claude-code-design/tree/main/.claude/skills/export-pptx
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/bluzir/claude-code-design.git /tmp/claude-code-design
mkdir -p .claude/skills
cp -r /tmp/claude-code-design/.claude/skills/export-pptx .claude/skills/export-pptx

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Export Pptx in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Export Pptx on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Export Pptx is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Export PPTX

Screenshot-based PPTX export — each <section> inside <deck-stage> becomes one slide (1920×1080 image + optional speaker notes).

Preflight

Bash(which node) — if missing, tell user to install Node 20+

Check package.json has pptxgenjs + puppeteer — if not, run:


Bash(npm install -D pptxgenjs puppeteer)

(or tell user to run /doctor first)

Steps

Resolve paths:
- $0 = deck HTML (required)
- $1 = output (default: basename + .pptx)

Run the export script:


Bash(node scripts/export-pptx.mjs "<input>" "<output>")

Report size + path.

Script dependencies

scripts/export-pptx.mjs must exist. If missing, create it (see template in spec §4.5 or ask user to run /doctor).

What the script does

Launches headless Chromium (puppeteer)
Loads the deck HTML at 1920×1080
Reads <deck-stage>.totalSlides
For each slide: goToSlide(i), set noscale, page.screenshot at clip 0,0,1920,1080
Reads #speaker-notes JSON (if present) and attaches per-slide notes
Builds .pptx with pptxgenjs (16:9 layout, one PNG-background slide each)

Notes

Images can be large — 5 MB per slide at 1920×1080 is normal
For smaller files, pass --jpeg 0.8 to the script (compress to JPEG at 80% quality)
Not editable in PowerPoint — each slide is a raster image. For native-editable export, skill not supported in v3.

Frequently asked questions

What does the Export Pptx AI skill do?

Export an HTML deck to PPTX via per-slide screenshots. Requires Node + pptxgenjs + puppeteer (run /doctor first).

Why use Export Pptx on TypingMind?

Because you install it once and use it with any model. Export Pptx is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Export Pptx in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/bluzir/claude-code-design/tree/main/.claude/skills/export-pptx. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Export Pptx?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Export Pptx?

As many as you like. As long as a model supports skills, you can use Export Pptx with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Export Pptx AI skill free?

It is published on GitHub by bluzir. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
