switch_memory_library
Switch between memory libraries to manage data for different contexts or projects. The current session state is saved before the switch, ensuring continuity. Input the library name to activate the desired memory structure.
Instructions
Switch to a different memory library.
Allows you to switch between different memory libraries for different contexts or projects. Current session state is saved before switching.
Parameters:
library_name: Name of the library to switch to (required)
Returns success status and message.
