memoryoss_storeSave important information to long-term memory so you can recall it in future sessions. Store facts, decisions, user preferences, project context, and key findings. Call this whenever you learn something worth remembering - if in doubt, store it. Memories persist across sessions and are searchable by content.
memoryoss_updateUpdate an existing memory by ID. Use this when information has changed - e.g. a user preference was corrected or a fact is outdated. Pass the memory ID from a previous recall result.
memoryoss_forgetDelete memories by their IDs. Use when the user asks you to forget something or when stored information is wrong and should not be updated but removed entirely.
