What they contain
- Top‑level Nodes (Agents or Flows) that may contain other components.
- Configuration that applies to the Project scope (e.g., variables).
Exposure
- Only top‑level Agents/Flows can be exposed as APIs or Schedules (configured under Execute).
tip: Model your domain — Map your domain’s entry points (API endpoints, schedules) to top‑level Nodes and keep deeper logic inside sub‑Flows or Actions.
