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 failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: dl.google.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.

    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

About this skill

What it does

This skill enables AI agents to generate, render, and export Mermaid diagrams directly within their workflow. It allows the agent to visualize complex data structures, system architectures, and process flows using text-based diagram definitions.

When to use it

  • You need to quickly visualize a software architecture or database schema without leaving your chat interface.
  • The AI agent needs to convert a textual description of a workflow into a renderable flowchart.
  • You want to generate documentation diagrams programmatically for version control integration.
  • You require the agent to produce SVG or PNG outputs from Mermaid syntax for embedding in reports.

Key capabilities

  • Generates valid Mermaid.js syntax from natural language prompts.
  • Renders diagrams directly in the chat output for immediate visual inspection.
  • Supports various diagram types including flowcharts, class diagrams, and sequence diagrams.
  • Exports rendered diagrams to image formats like SVG or PNG.

Example prompts

  • "Create a flowchart showing the user authentication process for our new mobile app."
  • "Generate a class diagram representing the relationships between Order, Customer, and Product entities in our database."
  • "Convert this text description of a deployment pipeline into a renderable Mermaid sequence diagram and save it as an SVG."

Tips & gotchas

Ensure your prompt provides sufficient context about the specific nodes and connections you want to visualize, as vague descriptions may result in generic diagrams. While the skill handles rendering, complex diagrams with many interconnections might require iterative refinement of the initial prompt to achieve the desired layout.
