Drawio Skill skill

drawio-skillAgents365-ai/drawio-skillskills/drawio-skill/SKILL.md

Create and edit draw.io/diagrams.net diagrams as editable `.drawio` files. Covers architecture, UML/ERD/sequence, BPMN, network, and swimlane views authored from a description or converted from code, IaC, SQL, and API schemas, plus sync, query, test, review, export, and publish of existing diagrams. Use when the user asks for draw.io/diagrams.net or an editable diagram; prefer Mermaid/PlantUML when diagrams-as-code is enough.

Install the Drawio Skill skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/Agents365-ai/drawio-skill --skill drawio-skill

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/Agents365-ai/drawio-skill.git /tmp/drawio-skill
mkdir -p ~/.claude/skills
cp -R /tmp/drawio-skill/skills/drawio-skill ~/.claude/skills/drawio-skill

For one project only, copy the folder into .claude/skills/ in that project instead. It is marked disable-model-invocation, so the agent won't pick it on its own: you run it as /drawio-skill.
