Document Render Skill

Automatically render markdown documents as beautifully formatted HTML pages with syntax highlighting, math formulas, Mermaid diagrams, and scroll animations. Features sticky TOC navigation, zoom/pan Mermaid controls, enhanced tables, and collapsible code blocks.

When to Use

• User asks to "view as HTML", "render in browser", "preview as a web page", or "open in browser"
• Content contains complex tables, Mermaid diagrams, or math formulas that render poorly in terminal
• Presenting plans, specs, or documentation for review where visual formatting matters
• User says "make this readable" or "format this nicely" for long structured content
• Proactive: About to output a table with 4+ rows or 3+ columns in the terminal
• Proactive: About to output a comparison, audit, feature matrix, or status report as ASCII
• Proactive: Conversation output would exceed ~50 lines of structured content (lists, tables, code blocks)

When NOT to Use

• Short content (under 20 lines) that renders fine in the terminal
• User explicitly wants terminal/text output
• /view-doc command was already invoked in this interaction
• User is asking to edit or modify the content, not view it
• Content is not markdown or structured text

Workflow

1. Determine source: Either a file path the user specified, or inline content from the conversation
2. If file path: Run the render script directly with that path
3. If inline content: Write the content to a temp file /tmp/viz-doc-{timestamp}.md using the Write tool, then run the render script with that temp file path

Rendering

Run the render script via Bash:

bash "${CLAUDE_PLUGIN_ROOT}/lib/render.sh" "{file_path}" "doc-{name}"

The script handles base64 encoding, HTML generation, and opening in the browser.
