forget

Delete a memory by its key.

Parameters

Parameter	Type	Required	Description
key	string	Yes	The exact key of the memory to delete.

Behaviour

• Permanently deletes the memory with the given key.
• Raises an error if no memory with that key exists.

Examples

Forget the memory about the old database URL — we've migrated.

→ agent calls forget("project/old-db-url")

Delete everything we stored about the cancelled feature.

→ agent may call forget for each relevant key, or use list_memories first to find them.
