  • 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.

  • 1 bundled files

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

  • Open source

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

Installation

Install the Email Html Mjml 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.
    https://github.com/podo/design-agent-skills/tree/main/skills/email-html-mjml
  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.

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/podo/design-agent-skills.git /tmp/design-agent-skills
mkdir -p .claude/skills
cp -r /tmp/design-agent-skills/skills/email-html-mjml .claude/skills/email-html-mjml
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Email Html Mjml 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 Email Html Mjml 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 Email Html Mjml 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.

email-html-mjml

Catalogue stub — full skill: framix-team/skill-email-html-mjml

Decision tree

  1. Is the full skill already installed?

    • Global: f=~/.agents/skills/email-html-mjml/SKILL.md; [ -f "$f" ] && ! grep -q "^das:" "$f" && echo "installed" || echo "pointer"
    • Project: f=.agents/skills/email-html-mjml/SKILL.md; [ -f "$f" ] && ! grep -q "^das:" "$f" && echo "installed" || echo "pointer"
    • installed → the skill is installed as email-html-mjml, invoke it and proceed
    • pointer → go to step 2

  2. Detect scope, then install:

    bash
    [ -e ~/.agents/skills/email-html-mjml ] && echo "global" || echo "project"

    Global:

    bash
    npx skills add framix-team/skill-email-html-mjml --skill email-html-mjml -g -y

    Project:

    bash
    npx skills add framix-team/skill-email-html-mjml --skill email-html-mjml -y

    Claude Code: send a command as a chat message starting with ! to run it without leaving the conversation.

Heads-up

  • Requires: Node.js 20 or later; MJML installed per project (npm install -D mjml), never globally
  • License: MIT

Invoke after install

  • Skill name: email-html-mjml
  • Trigger phrases: "MJML", "HTML email", "email template", "Outlook-safe email"

What it does

Generates production-ready HTML email using MJML 5.x as the authoring layer. MJML's responsive components compile to table-based HTML that is compatible with Outlook 2013 through 365, Gmail web and mobile, Apple Mail, and other major clients. The skill ships component references, example templates (newsletter, order confirmation, promo, basic layout) and compile instructions; it always delivers the .mjml source and the compiled .html, validated with MJML's strict mode and checked against Gmail's 102 KB clipping limit. Output follows accessibility rules (alt text, titles, contrast). The skill self-activates when asked to create, compile, or troubleshoot any HTML email.

It compiles with npx mjml, so Node.js 20 or later is required, and MJML itself is installed per project (npm install -D mjml).

When NOT to use

  • Marketing web page HTML — use design-html instead
  • Animated web content or interactive landing pages
  • Email rendering testing across clients (use a dedicated email testing service like Litmus)

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 Email Html Mjml AI skill do?

Generates cross-client responsive HTML email from MJML 5.x — Outlook 2013-365 safe, Gmail-optimized, WCAG 2.1 AA accessible. Triggers automatically when asked to create, compile, or troubleshoot HTML email. Compiles with npx mjml, so it needs Node.js 20+.

Why use Email Html Mjml on TypingMind?

Because you install it once and use it with any model. Email Html Mjml 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 Email Html Mjml in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/podo/design-agent-skills/tree/main/skills/email-html-mjml. 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 Email Html Mjml?

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 Email Html Mjml?

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

Is the Email Html Mjml AI skill free?

Yes. It is published on GitHub by podo 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.
