This is a learning signal, not a log: positive feedback raises a memory's ranking so it surfaces faster next time (across all of the user's tools), negative feedback lowers it so other memories out-rank it — nothing is erased and nothing decays with time. Use it after an answer that relied on or rejected memories from memory_read: pass the ids of those memories as memory_ids, with outcome 1 when they helped and -1 when they were wrong or stale. For memories read from a shared room, also pass that room's address as domain; your own memories need no domain. A read-only room member cannot rate the room's memories.", + "description": "Rate memories returned by memory_read to help improve future retrieval ranking.
