Skill that gives Claude the ability to generate Excalidraw diagrams.
This skill teaches Claude to produce Excalidraw .excalidraw JSON files — architecture diagrams, sequence diagrams, mind maps — that open natively in Excalidraw and stay editable. No screenshot-and-pray.
متى تستخدمه: You want a diagram you can iterate on, not a static PNG.

الخطوات
Describe the system
Using the Excalidraw skill, draw our auth flow: SPA → API gateway → auth-service → Postgres → emit event to Kafka.✓ تم النسخ
→ A .excalidraw file with labeled boxes + arrows
Iterate
Add a Redis cache between API gateway and auth-service.✓ تم النسخ
→ Updated file with the new node + correct re-routed arrows
النتيجة: A diagram you actually edit, not redraw.
المزالق
For very large diagrams (>30 nodes) auto-layout struggles — For very large diagrams (>30 nodes) auto-layout struggles — split into multiple diagrams or group by concern.

الأخطاء الشائعة وحلولها
file doesn't open in Excalidraw
Make sure the file ends with .excalidraw and is valid JSON. The skill outputs both, but check the extension.
تحقق: Open at excalidraw.com → load file
arrows pointing wrong way
Excalidraw's arrow startBinding/endBinding matters. The skill's templates handle it, but custom edits can break it.
