What problem does it solve? Source files like SQL, Python, Markdown, and YAML do not print well natively, and standard printouts leave no room for handwritten edits. This Skill converts any source file into a self-contained HTML page with mandatory double-spacing and wider margins so a reviewer can mark it up with a pen on paper. ## Core Features & Use Cases - Format-aware rendering: Handles 16+ formats including SQL, Python, JS/TS, YAML, JSON, Markdown, CSV, and shell, with print-safe syntax highlighting for code and rendered prose for Markdown. - Editing-optimized print CSS: Enforces double-spaced body text (line-height 2.0-2.2), wider @page margins (0.9in x 1.0in) for marginalia, page numbers, and document titles in headers/footers. - Mermaid diagram support: Pre-renders Mermaid blocks to inline SVG via mmdc, with a documented CDN fallback when the user is online at print time. - Use Case: A database schema.sql and an architecture.md need a paper review pass by a partner. Run the Skill on both files to produce schema-sql-print-edit.html and architecture-md-print-edit.html in the print-queue folder, then open each in a browser and press Ctrl+P. ## Quick Start Print the file docs/methodology-spec.md so I can mark it up on paper with double-spacing and wide margins.
