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 inference-sh/skills at c2d5678f14.

    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 design high-converting marketing emails using the inference.sh CLI. It leverages AI-generated visuals and provides guidelines for email width, layout, font sizes, and subject lines to optimize for readability and engagement across various devices and email clients. The tool focuses on creating visually appealing and effective email headers and banners.

When to use it

  • Generating header banners for marketing emails.
  • Creating email designs that adhere to standard rendering guidelines (e.g., Gmail, Outlook).
  • Developing subject lines using proven formulas like questions, how-to guides, or personalized greetings.
  • Designing preview text to enhance the appeal of an email in a recipient's inbox.
  • Ensuring emails are responsive and readable on mobile devices.

Key capabilities

  • Generates email header banners via the infsh/html-to-image application.
  • Provides guidelines for maximum email width (600px) and mobile responsiveness (320-414px).
  • Offers recommendations for font sizes, line heights, and layout structures (single or two-column).
  • Suggests subject line formulas to improve open rates.
  • Includes rules for effective preview text design.

Example prompts

  • "Generate an email header banner with a Spring Sale promotion."
  • "Create a subject line using the question formula about deployment practices."
  • "Design preview text that highlights the key benefit of this week's report."

Tips & gotchas

  • Requires the inference.sh CLI (infsh) to be installed and configured with infsh login.
  • Email designs should adhere to the specified constraints (e.g., max width, single-column layout) for optimal rendering across different email clients.
  • Subject lines containing spam trigger words ("free," "act now") should be avoided.
