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.
58 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by telagod on GitHub. Read the source before you install it.

Installation

Install the Creating Presentations 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/telagod/code-abyss/tree/main/skills/creating-presentations
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/telagod/code-abyss.git /tmp/code-abyss
mkdir -p .claude/skills
cp -r /tmp/code-abyss/skills/creating-presentations .claude/skills/creating-presentations

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

Use it in TypingMind

Enable Creating Presentations 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 Creating Presentations 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 Creating Presentations 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.

PPTX Processing

.pptx is a ZIP archive of XML and resources. Choose workflow by intent.

Workflow Decision

Intent	Workflow	Reference
Read text	markitdown → markdown	thumbnails-and-conversion.md
Analyze layout / comments / theme	unpack → raw XML	thumbnails-and-conversion.md
Create new from scratch	html2pptx	html2pptx.md + design-patterns.md
Create using template	rearrange + inventory + replace	template-workflow.md
Edit existing slides	unpack → OOXML → pack	ooxml.md
Visual review	thumbnail grids	thumbnails-and-conversion.md

Iron Rules

Color choice is design — see palettes.md, state your approach BEFORE code.
Web-safe fonts only — Arial, Helvetica, Times New Roman, Georgia, Courier New, Verdana, Tahoma, Trebuchet MS, Impact.
Layout matches content count — 2 items → 2 columns; 3 → 3; never force.
Validate visually — always generate thumbnails after creation, inspect for cutoff/overlap/contrast.

Create New (without template) — html2pptx

MANDATORY — READ ENTIRE FILE: html2pptx.md. NEVER set range limits.
Create HTML per slide (e.g., 720pt × 405pt for 16:9)
- Use <p>, <h1>–<h6>, <ul>, <ol>
- class="placeholder" for chart/table areas (gray bg for visibility)
- CRITICAL: Rasterize gradients & icons as PNG via Sharp first, then reference in HTML
- Use full-slide or two-column layout for charts/tables — never vertical stack
Run scripts/html2pptx.js to convert
- html2pptx() per HTML file
- Charts/tables via PptxGenJS API on placeholders
- pptx.writeFile() to save
Visual validation — python scripts/thumbnail.py output.pptx workspace/thumbnails --cols 4
- Inspect for: text cutoff, overlap, positioning, contrast
- Adjust HTML margins/spacing/colors, regenerate, repeat

Create with Template

See template-workflow.md for full 7-step workflow (extract → inventory → outline → rearrange → inventory text → generate replacements → apply).

Edit Existing Presentation

MANDATORY — READ ENTIRE FILE: ooxml.md (~500 lines). NEVER set range limits.
python ooxml/scripts/unpack.py <file> <dir>
Edit XML (primarily ppt/slides/slide{N}.xml)
CRITICAL — validate after each edit: python ooxml/scripts/validate.py <dir> --original <file>
python ooxml/scripts/pack.py <dir> <file>

Code Style

Concise code, no verbose names, no unnecessary print statements.

Dependencies

Package	Install	Purpose
markitdown	`pip install "markitdown[pptx]"`	Text extraction

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Creating Presentations AI skill do?

Why use Creating Presentations on TypingMind?

Because you install it once and use it with any model. Creating Presentations 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 Creating Presentations in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/telagod/code-abyss/tree/main/skills/creating-presentations. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Creating Presentations?

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 Creating Presentations?

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

Is the Creating Presentations AI skill free?

Yes. It is published on GitHub by telagod under the MIT license. 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.
