 "steps": [
  "Run `git clone https://github.com/weike-zhang/architecture-canvas.git` and then `cd architecture-canvas`.",
  "Run `python3 start.py` to set up the environment and build the page, then open http://127.0.0.1:5093.",

 "agent_prompt": "Using the architecture-canvas repo at https://github.com/weike-zhang/architecture-canvas, run python3 demo.py --output demo-session.json, import that file into the local page, and export the diagram as SVG. Expected output: an SVG file of the sample knowledge assistant diagram. Verify that the file opens offline and that no model or search request was made.",
