## Rules for an agent

- A public notebook can be loaded as an ES module from api.observablehq.com/@user/notebook.js?v=4 and run with @observablehq/runtime; for new projects prefer the open-source Framework or Notebook Kit (ISC).
- Keep the ISC copyright notice when you copy Observable's library code
- Check each notebook's own license before reusing its code or data; notebooks belong to their authors
