- cathrynlavery/diagram-design is a skill package for Claude Code, Codex, Factory Droid, Pi and other Agent Skills-compatible hosts, now at 38.3k stars and 2.4k forks.
- It offers 39 "editorial" diagram types rendered as self-contained HTML + SVG with no Mermaid. Version 2.5.10 adds ten more layout grammars: Sankey, fishbone, Wardley map, kanban, user journey, deployment, dependency graph, UML class, story map, and database schema.
- v2.0 introduced flywheel diagrams with a shared-memory hub ("The Loop"), and v2.3 added semantic system patterns with optional accessible motion; static output remains the default. Distributed as Claude/Codex plugins for direct use in agent workflows.
