cathrynlavery/diagram-design Takes #1 on GitHub Trending With +2,855 Stars in a Day — 29 Editorial Diagram Types Shipped as a Claude Code Plugin
The repo tops GitHub Trending today at 12,735 stars after gaining 2,855 in 24 hours, packaging 29 diagram types (architecture, sequence, swimlane, state machine, Gantt, timelines) as self-contained HTML+SVG with no external dependencies. It installs via `/plugin marketplace add cathrynlavery/diagram-design`, extracts brand colors and fonts from your site, imports draw.io and Mermaid files, exports PNG/SVG, and runs WCAG AA contrast checks. The loading model is the interesting part for builders: a flowchart request pulls one type reference plus the skill file rather than all 29, which is how a 29-template skill stays cheap in context.
