beautiful-mermaid
Render beautiful Mermaid diagrams as SVGs or ASCII art. Use when user sends Mermaid code blocks (\`\`\`mermaid ... \`\`\`) and wants to visualize them. Supports: Flowcharts, State, Sequence, Class, ER diagrams. Features: Ultra-fast (100+ diagrams <500ms), zero DOM dependencies, 15 built-in themes, Shiki theme compatibility. Perfect for: Telegram messages, terminal output, web interfaces, CLI tools.
Why use this skill?
Install the beautiful-mermaid skill to render high-speed SVG and ASCII diagrams from code. Perfect for automated documentation, system mapping, and visual flowcharts.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/ntlx/beautiful-mermaidWhat This Skill Does
The beautiful-mermaid skill for OpenClaw is a high-performance, dependency-free rendering engine designed to bridge the gap between abstract code and visual clarity. It acts as an internal transformer that converts Mermaid.js syntax into high-fidelity SVG documents or structured ASCII graphics. Designed for the AI era, it leverages an ultra-fast engine capable of processing over 100 diagrams in under 500ms, making it ideal for real-time interaction in chat interfaces, terminal windows, or web-based dashboards. It supports a comprehensive range of Mermaid diagram types, including Flowcharts, State machines, Sequence diagrams, Class structures, and Entity-Relationship (ER) models. With 15 built-in professional themes ranging from Tokyo Night to Catppuccin and Solarized, it ensures your documentation looks consistent and aesthetically pleasing across all environments.
Installation
You can integrate this skill into your OpenClaw environment using the following command:
clawhub install openclaw/skills/skills/ntlx/beautiful-mermaid
Ensure your project environment has the necessary node-based dependencies installed via your preferred package manager (npm, bun, or pnpm).
Use Cases
- Visualizing Complex Logic: Automatically render flowcharts from code blocks whenever a user shares a technical workflow.
- Terminal-Based Documentation: Provide developers with instant ASCII representations of system architectures directly in their CLI.
- Themed Reports: Generate consistent SVG visualizations for automated reports, adhering to a specific design language (e.g., matching dark mode themes of a web app).
- Rapid Prototyping: Quickly transform rough brainstorming sketches into clean, professional diagrams during an AI-assisted architecture session.
Example Prompts
- "Visualize the following logic as a professional SVG flowchart:
mermaid graph TD; A-->B; B-->C;" - "Convert this sequence diagram into a terminal-friendly ASCII block so I can copy-paste it into my commit message:
mermaid sequenceDiagram Alice->>Bob: Hello!" - "Render the current ER diagram using the 'tokyo-night' theme to match my current development environment."
Tips & Limitations
- Theme Selection: Always prefer built-in themes for consistent output. If you require specific branding, use the Enriched Theme configuration to define exact hex codes for nodes, edges, and accents.
- Performance: While the skill is optimized for speed, extremely large diagrams (e.g., thousands of nodes) may impact rendering performance. Aim for modular diagrams to maintain responsiveness.
- Zero Dependency: This skill is built without DOM dependencies, meaning it is safe to use in server-side contexts like Node.js or edge workers, making it more portable than standard browser-based Mermaid rendering tools.
