Use when the user asks to render a Mermaid diagram.\n---\n\n# Beautiful Mermaid Diagram Rendering\n\nRender Mermaid diagrams as SVG and PNG images using the Beautiful Mermaid library.\n\n## Dependencies\n\nThis skill requires the `agent-browser` skill for PNG rendering. Load it before proceeding with PNG capture.\n\n## Supported Diagram Types\n\n- **Flowchart** - Process flows, decision trees, CI/CD pipelines\n- **Sequence** - API calls, OAuth flows, database transactions\n- **State** - State machines, connection lifecycles\n- **Class** - UML class diagrams, design patterns\n- **Entity-Relationship** - Database schemas, data models\n\n## Available Themes\n\nDefault, Dracula, Solarized, Zinc Dark, Tokyo Night, Tokyo Night Storm, Tokyo Night Light, Catppuccin Latte, Nord, Nord Light, GitHub Dark, GitHub Light, One Dark.\n\nIf no theme is specified, use `default`.\n\n## Common Syntax Patterns\n\n### Flowchart Edge Labels\n\nUse pipe syntax for edge labels:\n\n```mermaid\nA -->|label| B\nA ---|label| B\n```\n\nAvoid space-dash syntax which can cause incomplete renders:\n\n```mermaid\nA -- label --> B   # May cause issues\n```\n\n### Node Labels with Special Characters\n\nWrap labels containing special characters in quotes:\n\n```mermaid\nA[\"Label with (parens)\"]\nB[\"Label with / slash\"]\n```\n\n## Workflow\n\n### Step 1: Generate or Validate Mermaid Code\n\nIf the user provides a description rather than code, generate valid Mermaid syntax. Consult `references/mermaid-syntax.md` for full syntax details.\n\n### Step 2: Render SVG\n\nRun the rendering script to produce an SVG file:\n\n```bash\nbun run scripts/render.ts --code \"graph TD; A-->B\" --output diagram --theme default\n```\n\nOr from a file:\n\n```bash\nbun run scripts/render.ts --input diagram.mmd --output diagram --theme tokyo-night\n```\n\nAlternative runtimes:\n```bash\nnpx tsx scripts/render.ts --code \"...\" --output diagram\ndeno run --allow-read --allow-write --allow-net scripts/render.ts --code \"...\" --output diagram\n```\n\nThis produces `<output>.svg` in the current working directory.\n\n### Step 3: Create HTML Wrapper\n\nRun the HTML wrapper script to prepare for screenshot:\n\n```bash\nbun run scripts/create-html.ts --svg diagram.svg --output diagram.html\n```\n\nThis creates a minimal HTML file that displays the SVG with proper padding and background.\n\n### Step 4: Capture High-Resolution PNG with agent-browser\n\nUse the agent-browser CLI to capture a high-quality screenshot. Refer to the `agent-browser` skill for full CLI documentation.\n\n```bash\n# Set 4K viewport for high-resolution capture\nagent-browser set viewport 3840 2160\n\n# Open the HTML wrapper\nagent-browser open \"file://$(pwd)/diagram.html\"\n\n# Wait for render to complete\nagent-browser wait 1000\n\n# Capture full-page screenshot\nagent-browser screenshot --full diagram.png\n\n# Close browser\nagent-browser close\n```\n\nFor even higher resolution on complex diagrams, increase the viewport further or use the `--padding` option when creating the HTML wrapper to give the diagram more space.\n\n### Step 5: Clean Up Intermediary Files\n\nAfter rendering, remove all intermediary files. Only the final `.svg` and `.png` should remain.\n\nFiles to clean up:\n- The HTML wrapper file (e.g., `diagram.html`)\n- Any temporary `.mmd` files created to hold diagram code\n- Any other files created during the rendering process\n\n```bash\nrm diagram.html\n```\n\nIf a temporary `.mmd` file was created, remove it as well.\n\n## Output\n\nBoth outputs are always produced:\n- **SVG**: Vector format, infinitely scalable, small file size\n- **PNG**: High-resolution raster, captured at 4K (3840×2160) viewport with minimum 1200px diagram width\n\nFiles are saved to the current working directory unless the user explicitly specifies a different path.\n\n## Theme Selection Guide\n\n| Theme | Background | Best For |\n|-------|------------|----------|\n| default | Light grey | General use |\n| dracula | Dark purple | Dark mode preference |\n| tokyo-night | Dark blue | Modern dark aesthetic |\n| tokyo-night-storm | Darker blue | Higher contrast |\n| nord | Dark arctic | Muted, calm visuals |\n| nord-light | Light arctic | Light mode with soft tones |\n| github-dark | GitHub dark | Matches GitHub UI |\n| github-light | GitHub light | Matches GitHub UI |\n| catppuccin-latte | Warm light | Soft pastel aesthetic |\n| solarized | Tan/cream | Solarized colour scheme |\n| one-dark | Atom dark | Atom editor aesthetic |\n| zinc-dark | Neutral dark | Minimal, no colour bias |\n\n## Troubleshooting\n\n### Theme not applied\n\nCheck the render script output for the `bg` and `fg` values, or inspect the SVG's opening tag for `--bg` and `--fg` CSS custom properties.\n\n### Diagram appears cut off or incomplete\n\n- Check edge label syntax — use `-->|label|` pipe notation, not `-- label -->`\n- Verify all node IDs are unique\n- Check for unclosed brackets in node labels\n\n### Render produces empty or malformed SVG\n\n- Validate Mermaid syntax at https://mermaid.live before rendering\n- Check for special characters that need escaping (wrap in quotes)\n- Ensure flowchart direction is specified (`graph TD`, `graph LR`, etc.)\n","tagline":"Render Mermaid diagrams as SVG and PNG using the Beautiful Mermaid library.
