cathrynlavery/diagram-design sits at 12,735 stars, packaging 29 diagram types (architecture, sequence, swimlane, state machine, Gantt, timelines) as self-contained HTML+SVG with zero dependencies. Installs via /plugin marketplace add cathrynlavery/diagram-design, extracts brand colors and fonts from your site, imports draw.io and Mermaid, exports PNG/SVG, runs WCAG AA contrast checks. The loading model is the part builders should study: a flowchart request pulls one type reference plus the skill file, not all 29. That's how a 29-template skill stays cheap in context.
