Excalidraw

Purpose

Hand-drawn-style diagramming tool. Ideal for architecture diagrams, flowcharts, and conceptual sketches that benefit from an informal visual style.

How we use it

Two integration paths: 1. MCP server (mcp__claude_ai_Excalidraw__*) — programmatic creation, checkpoint save/read 2. Obsidian plugin — embed Excalidraw drawings directly in vault notes (plugin installed per .obsidian/plugins/obsidian-excalidraw-plugin/)

Setup & credentials

Local use — no credentials. Obsidian plugin provides in-vault embedding.

Owner

tbd — likely code.platform (architectural diagrams) or chief.staff (governance diagrams)
