Skill not invoked when you ask for a diagram

Mention 'excalidraw' or 'diagram' explicitly; or verify the clone exists.

SKILL.md frontmatter wrong

Re-clone; the frontmatter drives auto-activation.

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.

왜 쓰나요

핵심 기능

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

사용 사례

실전 활용법: excalidraw-skill

Sketch a microservices architecture diagram from a prose description

👤 Engineers writing design docs ⏱ ~10 min beginner

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

흐름

Describe the system

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

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

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

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

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

→ File saved to CWD

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

함정

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

함께 쓰기: filesystem

Generate a sequence diagram from an API interaction you just debugged

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

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

흐름

Paste the log or describe the flow

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

→ Sequence diagram with correct arrows and return messages
Refine

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

→ Alternative flow rendered distinctly

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

도구

이 MCP가 노출하는 것

도구	입력	언제 호출	비용
generate_flowchart	process description	Process has decision points and sequential steps	0 via Kroki, 0 local

export_png	diagram ID	Need rasterized image for docs that don't support SVG	0 (requires local CLI)

비용 및 제한

운영 비용

API 쿼터: Kroki has no explicit quota but don't hammer it
호출당 토큰: Diagram specs are compact (<2k tokens typically)
금액: Free — skills are local files. Kroki is free.
팁: Use Kroki for one-offs, install excalidraw-brute-export-cli only if you need offline.

보안

권한, 시크릿, 파급범위

자격 증명 저장: No credentials — pure prompts

데이터 외부 송신: 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.

문제 해결

자주 발생하는 오류와 해결

Wrong trigger keywords — Claude writes Mermaid instead

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