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.

About this skill

What it does

This skill enables AI agents to verify email snapshot accuracy against original rendered content. It's designed for testing email templates, particularly when using MJML, and helps identify discrepancies or unintended changes that might occur during rendering or template updates. The skill uses snapshot testing techniques to capture the rendered HTML and compare it against a baseline, flagging any unexpected differences.

When to use it

  • Testing email template rendering for regressions (ensuring new code doesn't break existing functionality).
  • Validating MJML templates compile to expected HTML output.
  • Reviewing email changes during code review by providing visual diffs of rendered HTML.
  • Ensuring variable substitution within email templates works correctly.

Key capabilities

  • Captures rendered HTML as a snapshot for comparison.
  • Identifies discrepancies between the current and baseline HTML rendering.
  • Provides visual diffs to highlight changes in rendered output.
  • Supports integration with testing frameworks like Xunit, NUnit, and MSTest.

Example prompts

  • "Run an email template verification test for the 'UserSignupInvitation' template."
  • "Show me the diff between the current rendering of the email snapshot and the baseline."
  • "Verify that variable substitution is working correctly in the email template."

Tips & gotchas

  • Requires installation of the Verify.Xunit (or equivalent for other testing frameworks) NuGet package.
  • The first time a test is run, it creates a .verified.html file containing the initial snapshot. Subsequent runs compare against this baseline.
