  • 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 AIDotNet on GitHub. Read the source before you install it.

Installation

Install the Nodemailer 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/AIDotNet/MoYuCode.git /tmp/MoYuCode
mkdir -p .claude/skills
cp -r /tmp/MoYuCode/skills/tools/nodemailer .claude/skills/nodemailer
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Nodemailer 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 Nodemailer 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 Nodemailer 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.

Usage Examples

Basic Email

typescript

    subject: 'Welcome to My App',
    text: 'Hello, welcome to our platform!',
    html: '<h1>Hello</h1><p>Welcome to our platform!</p>',
  });
  
  console.log('Message sent:', info.messageId);
}

HTML Email with Template

typescript
async function sendWelcomeEmail(user: { name: string; email: string }) {
  const html = `
    <!DOCTYPE html>
    <html>
      <head>
        <style>
          .container { max-width: 600px; margin: 0 auto; font-family: Arial; }

            <h1>Welcome, ${user.name}!</h1>
          </div>
          <div class="content">
            <p>Thank you for joining our platform.</p>
            <a href="https://myapp.com/dashboard" class="button">Get Started</a>
          </div>
        </div>
      </body>
    </html>
  `;
  
  await transporter.sendMail({
    from: '"My App" <noreply@myapp.com>',
    to: user.email,
    subject: `Welcome, ${user.name}!`,
    html,
  });
}

Email with Attachments

typescript
async function sendEmailWithAttachment() {
  await transporter.sendMail({
    from: '"Reports" <reports@myapp.com>',
    to: 'manager@company.com',
    subject: 'Monthly Report',
    text: 'Please find the monthly report attached.',
    attachments: [
      {
        filename: 'report.pdf',
        path: './reports/monthly-report.pdf',
      },
      {
        filename: 'data.xlsx',
        content: Buffer.from('...'), // Buffer content
      },
      {
        filename: 'logo.png',
        path: './assets/logo.png',
        cid: 'logo@myapp', // For embedding in HTML
      },
    ],
    html: '<img src="cid:logo@myapp" /><p>See attached report.</p>',
  });
}

OAuth2 Authentication (Gmail)

typescript
const transporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    type: 'OAuth2',
    user: process.env.GMAIL_USER,
    clientId: process.env.GOOGLE_CLIENT_ID,
    clientSecret: process.env.GOOGLE_CLIENT_SECRET,
    refreshToken: process.env.GOOGLE_REFRESH_TOKEN,
  },
});

Email Queue with Rate Limiting

typescript
class EmailQueue {
  private queue: Array<() => Promise<void>> = [];
  private processing = false;
  
  async add(emailFn: () => Promise<void>) {
    this.queue.push(emailFn);
    this.process();
  }
  
  private async process() {
    if (this.processing) return;
    this.processing = true;
    
    while (this.queue.length > 0) {
      const emailFn = this.queue.shift()!;
      await emailFn();
      await new Promise(r => setTimeout(r, 1000)); // Rate limit
    }
    
    this.processing = false;

Frequently asked questions

What does the Nodemailer AI skill do?

从Node.js应用发送邮件。最流行的邮件发送模块，支持SMTP、OAuth2、附件和HTML模板。

Why use Nodemailer on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/AIDotNet/MoYuCode/tree/main/skills/tools/nodemailer. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Nodemailer?

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 Nodemailer?

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

Is the Nodemailer AI skill free?

Yes. It is published on GitHub by AIDotNet 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.
