 ### Adding Slash Commands
 
-Edit `src/jdo/repl/loop.py` in `handle_slash_command()`:
+Commands are implemented as handlers in `src/jdo/commands/handlers/`.
+Register new handlers in `src/jdo/commands/handlers/__init__.py`:
 
 ```python
-if command == "mycommand":
-    _handle_mycommand(args, db_session)
-    return True
+# In _HANDLERS dict
+CommandType.MYCOMMAND: MyCommandHandler,
 ```
