Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mermaid Diagrams Generate `.mmd` text files and export to PNG/SVG/PDF using `mmdc` (local) or Kroki API (no install). **Key advantage:** Text-based syntax with **fully automatic layout** — no x/y coordinates needed. ## When to use / when NOT to use **Use this skill for:** diagrams-as-code with automatic layout (flowchart, sequence, class, state, ER, gantt, mindmap, architecture) — text source that lives in git and embeds in Markdown. **Do NOT use it — route elsewhere — for:** - Pixel-precise placement, custom layout, branded icons, or heavy styling → **drawio**. - A hand-drawn / sketchy aesthetic → **excalidraw** or **tldraw**. - A freeform whiteboard or freehand strokes → **tldraw**. - Strict, conventional UML notation → **plantuml**. ## Prerequisites **Option A: Local (mmdc)** — also needs a headless Chrome (mmdc renders via Puppeteer) ```bash npm install -g @mermaid-js/mermaid-cli npx puppeteer browsers install chrome-headless-shell # required — mmdc has no bundled browser mmdc --version ``` …

How to install
mdr add agents365-ai/365-skills/mermaid-skill@sha256:2aef539150998344The line at the top of this page pins the label v1.3.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
