Search the user's memory in natural language. Returns the most relevant documents plus standalone facts distilled from their history. Use this first to ground any answer or action in what the user actually knows.

List the user's memory items within a recent time window, newest-first — a COMPLETE enumeration (not a relevance ranking). Use it for 'what did I do/save in the last N days' questions. Optionally restrict to one source.

Write a memory back to the user's store — a task outcome, a decision, or something the user just told you. It flows through the same distillation + reconciliation lifecycle as any ingested document.

Fetch the standing profile for the namespace — durable facts (static) plus what the user has been doing recently (dynamic). Inject this into your system prompt to start a session already knowing the user.
