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

Installation

Install the Code Snippet Images 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/freekmurze/dotfiles/tree/main/config/claude/skills/code-snippet-images
Enable the skill in any chat where you want it available.

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/freekmurze/dotfiles.git /tmp/dotfiles
mkdir -p .claude/skills
cp -r /tmp/dotfiles/config/claude/skills/code-snippet-images .claude/skills/code-snippet-images

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

Use it in TypingMind

Enable Code Snippet Images 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 Code Snippet Images 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 Code Snippet Images 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.

Code Snippet Images

Generate high-resolution code snippet PNGs using HTML templates rendered with Chrome headless at 2x scale.

Quick Start

Copy the template from assets/template.html to a temp file
Replace  with the title bar text (e.g., filename or description)
Replace  with syntax-highlighted HTML (see Syntax Highlighting below)
Render with scripts/render.sh:

bash
scripts/render.sh /tmp/snippet.html /tmp/snippet.png
# Produces 2400x1350 PNG (1200x675 at 2x scale)

Design Specs

Viewport: 1200×675px, rendered at 2x scale → 2400×1350px output
Style: Light theme, warm off-white (#f0ece8 background, #faf8f6 card)
Window chrome: macOS-style red/yellow/green dots, no badges or pills
Font: JetBrains Mono (loaded from Google Fonts), ligatures disabled
Code font size: 25px default (23px if code is longer, 20px if very dense). Use large fonts to fill the card.
No footer text below the code card
Color scheme: GitHub-light inspired syntax highlighting

Syntax Highlighting

Wrap code tokens in <span> with these classes:

Class	Color	Use for
`.keyword`	green #22863a	`use`, `function`, `class`, `return`, `new`, `fn`
`.string`	blue #032f62	`'quoted strings'`
`.method`	purple #6f42c1	method/function names
`.class-name`	purple #6f42c1	class and namespace names
`.facade`	purple #6f42c1	Facade names like `Pdf`
`.comment`	gray italic #6a737d	`// comments` and `# comments`
`.variable`	orange #e36209	`$variables`
`.named-arg`	orange #e36209	PHP named args `key:`
`.arrow`	dark #24292e	`->` and `=>`
`.punctuation`	dark #24292e	`()`, `{}`, `[]`, `;`, `::`
`.env-key`	green bold #22863a	`.env` keys
`.env-val`	blue #032f62	`.env` values
`.number`	blue #005cc5	numeric literals
`.type`	purple #6f42c1	type hints

Use <br> for line breaks. Use   for indentation (4× per level).

Example

html
<span class="keyword">use</span> <span class="class-name">App\Models\User</span><span class="punctuation">;</span><br><br>
<span class="variable">$users</span> <span class="punctuation">=</span> <span class="class-name">User</span><span class="punctuation">::</span><span class="method">where</span><span class="punctuation">(</span><span class="string">'active'</span><span class="punctuation">,</span> <span class="keyword">true</span><span class="punctuation">)-&gt;</span><span class="method">get</span><span class="punctuation">();</span>

Grid Composite (2×2)

For combining 4 snippets into one image (e.g., LinkedIn posts):

Copy assets/grid-2x2.html to a temp file
Fill in the 4  and  placeholders
Render at 2400×1350 native (no scaling needed since the grid is already 2400px wide):

bash
scripts/render.sh /tmp/grid.html /tmp/grid.png 2400 1350 1

Grid uses slightly smaller fonts (17px) and padding to fit 4 cards.

Render Script

scripts/render.sh <input.html> <output.png> [width] [height] [scale]

Param	Default	Notes
width	1200	Viewport width in px
height	675	Viewport height in px
scale	2	Device scale factor (2 = retina)

Tips

Adjust font size if code doesn't fit: change .code { font-size } in the HTML
Adjust card height: the card auto-sizes to content; body height may need increasing for long snippets
Arrow ligatures: template already disables ligatures (font-variant-ligatures: none) to prevent -> from rendering as →
Multiple images: create separate HTML files per snippet, render each independently
PHP code: prefer pdf() helper style over Pdf facade when showing Laravel examples (Spatie convention)
Keep code concise — these are for social media, not documentation

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 Code Snippet Images AI skill do?

Why use Code Snippet Images on TypingMind?

Because you install it once and use it with any model. Code Snippet Images 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 Code Snippet Images in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/freekmurze/dotfiles/tree/main/config/claude/skills/code-snippet-images. 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 Code Snippet Images?

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 Code Snippet Images?

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

Is the Code Snippet Images AI skill free?

It is published on GitHub by freekmurze. 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.
