plugin-ai-drawio

Overview

Embed a self-hosted draw.io editor inside the AI Employee chat with a single shared canvas, plus tools to create, inspect, edit, and append diagrams via chat.

Features

• Single shared canvas: The plugin keeps exactly ONE draw.io screen for the whole chat. The first time the AI displays a diagram, an "Open Diagram" button appears; once opened, every later display/edit call updates the SAME canvas in place — no new screen is created per reply.
• No server session / DB records: The self-hosted draw.io server keeps its data in the browser, so the plugin only pushes XML into the iframe. A lightweight list of XML schemas (title + XML per diagram) is kept in localStorage so diagrams survive page refreshes.
• Reopen behavior: If the user closes the canvas, the next AI tool call shows the "Open Diagram" button again so they can reopen the shared canvas.
• AI Diagram Generation: Ask the AI Employee to generate architectural flows, sequence diagrams, or mind maps.
• General AI Employee tools: All enabled AI Employees receive the Draw.io tools automatically; no per-employee tool or work-context registration is needed.
• Reliable editing: The AI inspects the current diagram before editing, so it receives the live XML and cell IDs from the canvas.

Usage

1. Activate the plugin in the Plugin Manager.
2. (Optional, admin) In plugin settings, set the self-hosted draw.io base URL (defaults to https://embed.diagrams.net).
3. Open AI Chat and request "Create a flowchart for user login". Click "Open Diagram" on the first result; subsequent replies update the same canvas.
