Store a durable fact, preference, decision, or correction so FUTURE sessions remember it. Call this whenever the user states something worth carrying forward — a preference, a project fact, a decision, a correction — without being asked. Memory persists across sessions and processes.

Recall what you already know before answering. Call this at the START of a session, and whenever the user refers to past context, their preferences, or the project history. Returns relevant memories via MMR retrieval (not a text match). If unsure whether you know something, search first.

Summarize what is currently in memory: counts plus the most recently stored facts. Reads the store directly — no embedding call, no network. Use to orient yourself at session start, or when the user asks what you remember. (selfFacets is always 0: this server does not run the engine's consolidation pass, so crystallization never happens.)

DESTRUCTIVE. Deletes EVERY memory whose content contains the query as a case-insensitive substring — not semantic, not a single-item delete, and there is no undo. A short query deletes broadly. Use only when the user corrects a stored fact or explicitly asks you to forget something, and prefer a long distinctive phrase; check memory_state first if unsure.
