  • 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.

  • 8 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by jezweb on GitHub. Read the source before you install it.

Installation

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

1

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.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. 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.
2

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/jezweb/claude-skills.git /tmp/claude-skills
mkdir -p .claude/skills
cp -r /tmp/claude-skills/plugins/design-assets/skills/favicon-gen .claude/skills/favicon-gen
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Favicon Gen 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 Favicon Gen 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 Favicon Gen 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.

Favicon Generator

Generate a complete favicon package from a logo, initials, or brand colours. Produces all required formats and HTML integration code.

Workflow

Step 1: Choose Your Approach

Have a logo with an icon element?
 YES -> Extract icon from logo
 NO  -> Have text/initials?
         YES -> Create monogram favicon
         NO  -> Use branded shape

Step 2: Create Source SVG

Extracted icon — copy icon paths from logo, centre in 32x32 viewBox, simplify for small sizes.

Monogram — use a template from assets/:

xml
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32">
  <circle cx="16" cy="16" r="16" fill="#0066cc"/>
  <text x="16" y="21" font-size="16" font-weight="bold"
        text-anchor="middle" fill="#ffffff" font-family="sans-serif">AC</text>
</svg>

Branded shape — circle (universal), rounded square (modern), shield (security), hexagon (tech).

SVG templates available in assets/ directory.

Step 3: Generate All Formats

Requires ImageMagick (convert command). Install if needed: brew install imagemagick (macOS) or apt install imagemagick (Linux).

bash
# ICO (16x16 + 32x32)
convert favicon.svg -define icon:auto-resize=16,32 favicon.ico

# Apple Touch Icon (180x180, SOLID background — transparent = black on iOS)
convert favicon.svg -resize 180x180 -background "#0066cc" -alpha remove apple-touch-icon.png

# Android/PWA icons
convert favicon.svg -resize 192x192 icon-192.png
convert favicon.svg -resize 512x512 icon-512.png

No ImageMagick? Use https://favicon.io to convert from the SVG instead.

Step 4: Create Web Manifest

Copy and customise assets/manifest.webmanifest:

json
{
  "name": "Your Business Name",
  "short_name": "Business",
  "icons": [
    { "src": "/icon-192.png", "sizes": "192x192", "type": "image/png" },
    { "src": "/icon-512.png", "sizes": "512x512", "type": "image/png" }
  ],
  "theme_color": "#0066cc",
  "background_color": "#ffffff",
  "display": "standalone"
}

Step 5: Add HTML Tags

html
<link rel="icon" type="image/svg+xml" href="/favicon.svg">
<link rel="icon" type="image/x-icon" href="/favicon.ico">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="manifest" href="/site.webmanifest">
<meta name="theme-color" content="#0066cc">

Place all files in site root (/public/ in Vite/React).


Critical Rules

  • Always generate ALL formats — SVG, ICO, apple-touch-icon, 192, 512, manifest
  • iOS icons MUST have solid backgrounds — transparent = black square
  • Always use bold font weight for monogram text (regular disappears at 16x16)
  • Test at 16x16 — if it's not legible, simplify
  • Never launch with CMS defaults (WordPress "W", etc.)

Asset Files

  • assets/favicon-svg-circle.svg — Circle monogram template
  • assets/favicon-svg-square.svg — Rounded square template
  • assets/favicon-svg-shield.svg — Shield template
  • assets/manifest.webmanifest — Web manifest template

Reference Files

  • references/format-guide.md — Complete format specifications
  • references/extraction-methods.md — Logo icon extraction steps
  • references/monogram-patterns.md — Advanced monogram design
  • references/shape-templates.md — Industry-specific shapes with SVG code

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 Favicon Gen AI skill do?

Generate custom favicons from logos, text, or brand colours. Produces favicon.svg, favicon.ico, apple-touch-icon.png, icon-192/512.png, and web manifest. Use whenever the user wants a favicon, mentions replacing a CMS default favicon, converting a logo into a favicon, creating branded initials icons, or troubleshooting favicon not displaying / iOS black square / missing manifest.

Why use Favicon Gen on TypingMind?

Because you install it once and use it with any model. Favicon Gen 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 Favicon Gen in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/jezweb/claude-skills/tree/main/plugins/design-assets/skills/favicon-gen. 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 Favicon Gen?

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 Favicon Gen?

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

Is the Favicon Gen AI skill free?

Yes. It is published on GitHub by jezweb 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.
