 - This applies to both the intelligent agent and the intelligent communication tool.
 - If `SYSTEM.md` is missing or empty, the app falls back to built-in defaults and logs a warning.
 
+## Goal File

+- `GOAL.md` is used when autoplay is enabled (`MISTLE_AUTOPLAY=true`).
+- On startup, the app launches the intelligent agent automatically and passes the contents of `GOAL.md` as runtime instructions.
+- If `GOAL.md` is missing or empty, autoplay still starts but without extra instructions.

 ## Tool Development
 
 - Implement new tools by subclassing `tools.Tool` and overriding `observe()` and `decide()`.
