Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned aaronontheweb/dotnet-skills at e426ed93a9.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides access to MJML email templates, enabling developers to generate responsive HTML emails using a simple XML-like syntax. It streamlines the creation of complex email layouts that are guaranteed to render correctly across various clients and devices.

When to use it

  • You need to build marketing campaigns or transactional emails that must look consistent on desktop and mobile.
  • Your team lacks deep expertise in writing raw HTML and CSS for email compatibility.
  • You want to iterate quickly on email designs without managing multiple style sheets.
  • You are integrating email generation into a .NET application workflow.

Key capabilities

  • Generates fully responsive HTML from MJML components.
  • Ensures cross-client rendering consistency.
  • Simplifies layout creation with a declarative syntax.
  • Integrates directly into development pipelines for automated email builds.

Example prompts

  • "Generate an MJML template for a newsletter header featuring a logo and social media icons."
  • "Create a responsive two-column product showcase using MJML components."
  • "Convert this XML-based MJML structure into production-ready HTML for our .NET backend."

Tips & gotchas

MJML is primarily designed for email clients that support standard web rendering, so test final outputs in major providers like Gmail and Outlook. While the syntax is intuitive, ensure your target email clients can handle the generated HTML or use a preprocessor to compile it before sending.
