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 mrgoonie/claudekit-skills at 80113d86bc.

    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

The Mermaid.js v11 skill enables AI agents to generate, render, and edit flowcharts, sequence diagrams, class diagrams, and other diagram types directly within chat interfaces using text-based syntax. It transforms complex structural data into visual representations without requiring external tools or manual drawing.

When to use it

  • Visualizing software architecture or system workflows during a code review session.
  • Creating sequence diagrams to explain API interactions or event flows in real-time.
  • Generating class diagrams to document object-oriented structures from natural language descriptions.
  • Quickly sketching out project timelines or dependency graphs for team alignment.

Key capabilities

  • Renders multiple diagram types including flowcharts, entity relationship diagrams (ERD), and Gantt charts.
  • Supports version 11 syntax updates for improved styling and layout options.
  • Allows inline editing of generated diagrams through natural language commands.
  • Integrates seamlessly into chat-based development environments for rapid prototyping.

Example prompts

"Create a flowchart showing the user authentication process with login, validation, and session creation steps." "Generate a sequence diagram illustrating how a frontend app communicates with a backend API to fetch user data." "Draw a class diagram for an e-commerce system including Product, Cart, and User classes with their relationships."

Tips & gotchas

Ensure your AI agent has access to the latest Mermaid.js v11 library to avoid syntax errors or rendering issues. Complex diagrams with many nodes may require simplification prompts for optimal clarity in chat interfaces.
