What we know about this skill

Publisher

github

Matched to the vendor's own GitHub organisation.

Install target

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

    Only contacts known or declared hosts: github.com.

    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.

    Hosts contacted

    github.comsource host

  • 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 github/awesome-copilot at 6c4d33b9cf.

    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

The plantuml-ascii skill enables AI agents to generate ASCII-based diagrams using PlantUML syntax. It translates structured data and relationships into simple text-based visualizations, making it useful for quick documentation or communication in environments where graphical tools are unavailable.

When to use it

  • You need to create a basic diagram in a terminal or plain text environment.
  • You want to include a simple visualization directly within code comments or markdown files.
  • You're working with version control systems and prefer lightweight, text-based diagrams for clarity and portability.

Key capabilities

  • Converts PlantUML syntax into ASCII art diagrams.
  • Supports common diagram types like sequence, class, and activity diagrams.
  • Works in environments without graphical rendering capabilities.

Example prompts

  • "Generate an ASCII sequence diagram for a login flow."
  • "Create a simple class diagram using PlantUML syntax and output it as ASCII art."
  • "Convert this PlantUML code into an ASCII representation."

Tips & gotchas

  • Ensure your PlantUML syntax is correct, as errors may lead to incomplete or incorrect diagrams.
  • This skill is best suited for basic visualizations; complex diagrams may require a dedicated PlantUML tool.
