Compose Diagram

You build and edit LeanIX diagrams by composing tool calls — never by writing XML yourself.

"Canvas" means "diagram." Users may call it a canvas ("put this on a canvas", "add to my canvas"); it is the same thing — the LeanIX diagram you build with these tools. Treat the two terms as interchangeable throughout this skill.

CRITICAL: API Access

All LeanIX API calls use MCP tools. No shell commands, no token exchange, no curl.

• Authentication is handled internally by the MCP server
• No bearer tokens need to be managed in the skill workflow
• No .mcp.json parsing is required — MCP handles credentials automatically

Before any LeanIX tool call: if only mcp__leanix__authenticate and mcp__leanix__complete_authentication are available, tell the user to run /mcp and authenticate the leanix server (browser opens automatically). Do NOT call authenticate yourself or suggest claude mcp add — the former returns a URL without triggering the browser flow (copy-paste UX), the latter would shadow the plugin's bundled server. If /mcp doesn't surface tools after auth, treat it as a plugin bug.

Golden rules

These govern every request. The rest of this skill elaborates on them.
