This is a comprehensive Mermaid diagramming tool that handles the full workflow from creation to rendering. It supports all 20+ diagram types (flowcharts, C4 architecture, AWS infrastructure with service icons, ERD, sequence, state diagrams, and more) and outputs to SVG, PNG, or ASCII. The skill shines in its opinionated approach to diagram quality, enforcing professional styling rules like soft line colors and curated color palettes instead of harsh defaults. It includes code-to-diagram analysis, syntax validation, and comes with detailed reference docs for C4 patterns and AWS architecture. The "Golden Rules" section is genuinely useful, particularly the warning about font rendering in headless Chrome. Reach for this when you need production-ready diagrams, not just quick sketches.
