Excalidraw Architecture

Produce an architecture diagram of the current project as an Excalidraw file (docs/architecture.excalidraw). The diagram shows services, entry points, data stores, and the edges between them — the kind of whiteboard sketch you'd draw in a design review.

Inspired by Bilgin Ibryam's Medium post on "Architecture diagrams as code with Claude Code + Excalidraw" — credit: @bibryam. This skill is a lightweight reimplementation for OpenClaw-style repos.

When to use

• New contributor asks "what does this repo look like?"
• User wants to update a stale architecture diagram after a refactor
• User says "draw me the system", "excalidraw the backend", "/excalidraw-architecture"
• Preparing a design doc and needs a canonical diagram
