Claude Code skill for turning natural-language system descriptions into hand-drawn Excalidraw diagrams — SVG/PNG/editable .excalidraw export.

Agents365-ai's Excalidraw skill auto-detects when a discussion needs a diagram (3+ components, multi-tier systems, workflows) and generates the right one: flowchart, architecture, sequence, mind map, or swimlane. Export via Kroki API (no install) or local excalidraw-brute-export-cli with Firefox. Editable .excalidraw files open directly on excalidraw.com.

Warum nutzen

Hauptfunktionen

Five diagram modes with specialized layout rules (flowchart, architecture, sequence, mind map, swimlane)
Auto-invokes when Claude detects architecture-worthy discussions
Three export paths: Kroki (curl, zero-install), local CLI (PNG/SVG), editable .excalidraw
Accepts Chinese or English natural-language input
Hand-drawn aesthetic avoids the sterile-looking AI diagram problem

Anwendungsfälle

Praxisnahe Nutzung: excalidraw-skill

Sketch a microservices architecture diagram from a prose description

👤 Engineers writing design docs ⏱ ~10 min beginner

Wann einsetzen: You're writing an RFC and want a diagram without opening a separate tool.

Ablauf

Describe the system

Use the excalidraw skill — draw a microservices e-commerce architecture with clients, API gateway, 4 services, RabbitMQ, and per-service databases.✓ Kopiert

→ Claude generates layout + exports an SVG via Kroki
Tweak and re-export

Add Redis in front of the product service and regenerate.✓ Kopiert

→ Updated diagram with Redis inserted, layout re-balanced
Save editable version

Save as .excalidraw so I can edit it on excalidraw.com.✓ Kopiert

→ File saved to CWD

Ergebnis: A hand-drawn-style architecture diagram in your doc in under 5 minutes.

Fallstricke

Diagram is cluttered for 10+ components — Ask Claude to group by tier first; the skill has layout rules for that

Kombinieren mit: filesystem

Generate a sequence diagram from an API interaction you just debugged

👤 Backend engineers documenting flows for teammates ⏱ ~10 min beginner

Wann einsetzen: You finally figured out the 5-service OAuth dance and want to document it.

Ablauf

Paste the log or describe the flow

Excalidraw skill — sequence diagram: user → frontend → auth service → identity provider → callback → session.✓ Kopiert

→ Sequence diagram with correct arrows and return messages
Refine

Add the error path when the IdP returns 401.✓ Kopiert

→ Alternative flow rendered distinctly

Ergebnis: A sequence diagram you can drop into the PR description.

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

excalidraw-skill + filesystem

Save generated diagrams directly into your docs folder

Generate the architecture diagram and save it to docs/architecture/v2.svg.✓ Kopiert

excalidraw-skill + github

Attach the diagram to a PR by committing it alongside the spec

Create the diagram, commit to docs/, and reference it in the PR body.✓ Kopiert

Werkzeuge

Was dieses MCP bereitstellt

Werkzeug	Eingaben	Wann aufrufen	Kosten
generate_flowchart	process description	Process has decision points and sequential steps	0 via Kroki, 0 local
generate_architecture	components + relationships	System has tiers or service boundaries	0
generate_sequence	actors + messages	Documenting a time-ordered interaction	0
export_png	diagram ID	Need rasterized image for docs that don't support SVG	0 (requires local CLI)

Kosten & Limits

Was der Betrieb kostet

API-Kontingent: Kroki has no explicit quota but don't hammer it
Tokens pro Aufruf: Diagram specs are compact (<2k tokens typically)
Kosten in €: Free — skills are local files. Kroki is free.
Tipp: Use Kroki for one-offs, install excalidraw-brute-export-cli only if you need offline.

Sicherheit

Rechte, Secrets, Reichweite

Credential-Speicherung: No credentials — pure prompts

Datenabfluss: Kroki path sends your diagram spec to kroki.io. Local CLI path sends nothing.

If your diagrams leak system internals, use the local CLI path instead of Kroki.

Fehlerbehebung

Häufige Fehler und Lösungen

Wrong trigger keywords — Claude writes Mermaid instead

Say 'excalidraw' explicitly; 'draw a diagram' alone can pick other tools.

Alternativen

excalidraw-skill vs. andere

Alternative	Wann stattdessen	Kompromiss
Mermaid via markdown	Your docs already render Mermaid natively (GitHub, etc.)	No hand-drawn aesthetic, less layout control
drawio via desktop app	You want click-heavy manual layout	Not agent-driven
