Build and maintain a durable personal knowledge base ("brain") in a TERSE store. Use when the user asks about `terse-brain`, research wiki, llm-wiki, source-cited notes, or long-lived knowledge that compounds across sessions — not a scratchpad and not the generic `default` TERSE namespace.
Durable agent memory in the TERSE `memory` namespace - remember / forget / recall / durable notes / cross-session facts. Use when the user says remember, forget, don't forget, save this for later, what do you remember, keep track of everything, or when a preference, decision, or milestone should outlive the chat. Also use at the start of any substantive multi-turn session to orient against durable user memory (run-this-first) before making assumptions about the user - orientation must happen even when no memory keyword appears. Depends on terse-mcp (terse_command, terse_info).
Read, write, and query durable structured state in a TERSE store. Use whenever the user asks about TERSE, or when the session needs shared persistent memory / notes / project state that must survive across turns, sessions, or agents — not a scratchpad and not a general database.
