## What it is
A coding agent skill that enables Claude Code and other skill-compatible agents to generate polished Excalidraw diagrams from natural language descriptions. It includes a Playwright-based render pipeline so the agent can visually validate and iterate on its own diagram output.

## Use cases
- generate excalidraw diagrams from natural language with claude code
- have my coding agent draw architecture diagrams automatically
- create diagrams that visually validate their own layout
- generate branded diagrams matching my company color palette
- visualize how a protocol streams events between agent and frontend
- add diagram generation capability to opencode or other agents

## When to choose
- you use Claude Code, OpenCode, or any agent supporting .claude/skills and want high-quality Excalidraw diagrams
- you want diagrams with meaningful visual structure rather than generic box-and-arrow layouts
- you need automated visual validation to catch overlapping text and misaligned arrows
- you want diagrams that follow a customizable brand palette

## When to avoid
- you need a standalone diagramming tool rather than an agent skill
- your coding agent does not support the skills directory format
- you need diagram formats other than Excalidraw
- you require a maintained, licensed dependency for production use (the repo has no license)
