“Clear the memory” is incomplete until you know which store is involved. An agent can retain: the current conversation, durable notes, stored transcripts, a search index, an external memory service, and reusable instructions or skills.
The same claim can appear in several of them. Correcting a note does not necessarily correct the transcript that supplied it; starting a chat can reload the same note; removing an index can leave its sources ready to be indexed again; a recurring task may use a skill that still contains yesterday’s bad instruction.
