Memory tools write and retrieve durable facts while filtering trivial context and secrets.
params remember tool Stores a durable fact after persistence policy classification. recall_memory tool Retrieves facts, decisions and summaries with citations. remember_user tool Writes durable user preferences/context to USER.md. finish_setup tool Completes agent genesis and can write one line about the user.
recall_memory returns cited lines, so the model can distinguish decisions, preferences, errors and summaries.
