Live repository

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 coder/mux at 54082e00e3.

    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 automatically generates screenshots for README files. It can create visual documentation of software projects, libraries, or any other tool that benefits from a graphical introduction. The generated images are suitable for inclusion directly into markdown READMEs, enhancing clarity and user understanding.

When to use it

  • Documenting CLI tools: Quickly capture the output of command-line interfaces to illustrate usage examples in a README.
  • Showcasing UI components: Generate screenshots of web or desktop application components for documentation purposes.
  • Creating tutorials: Illustrate step-by-step guides with visual aids directly within the README file.
  • Improving project onboarding: Provide new users with clear, visual instructions on how to use a project's features.

Key capabilities

  • Automated screenshot generation
  • Integration with markdown files
  • Suitable for CLI tools and UI components

Example prompts

  • "Generate screenshots of the my-cli-tool command with various flags."
  • "Create images showing how to use the 'login' button in my web application."
  • "Capture a screenshot sequence demonstrating the installation process."

Tips & gotchas

This skill likely requires access to the relevant software or UI being documented. Ensure that any necessary dependencies are installed and configured before using it.
