SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill turns Mermaid diagrams embedded in Markdown into static image files so the content works in tools that do not render Mermaid natively, such as Confluence, PDF pipelines, and slide decks.

Core Features & Use Cases

  • Diagram extraction and rendering: Finds Mermaid fenced blocks in document order and renders each one to PNG or SVG through the Mermaid CLI.
  • Markdown rewrite workflow: Produces a rewritten copy of the source Markdown where successful diagram fences are replaced with image references.
  • Operational safeguards: Verifies that the Mermaid CLI is available, reports the output directory and rewritten file path, and keeps going when individual diagrams fail so partial results are still useful.
  • Use case: Use it when you need to prepare a Markdown report for Confluence publishing, offline HTML generation, or presentation export with baked-in diagrams.

Quick Start

Ask the agent to check for Mermaid CLI availability and render the Mermaid blocks in your Markdown file into images, then return the rewritten file path and diagram count.
