The tools mostly target distinct memory operations: observe, recall, pin, trace, status, diary, persona, dream, and compact. The only notable overlap is pm_dream and pm_compact, since both perform consolidation/compression, though the descriptions distinguish immediate dreaming from core-area overflow compression with user consent.

All tools use the same pm_ prefix followed by a single lowercase verb or noun in snake_case: pm_pin, pm_diary, pm_status, pm_recall, pm_observe, pm_dream, pm_persona, pm_compact, pm_trace. The pattern is predictable and consistent throughout.

Nine tools is well-scoped for a memory/persona management server. Each tool corresponds to a meaningful operation in the memory lifecycle, and none appears redundant or trivial.

The surface covers observation, retrieval, pinning, tracing, status, diary export, persona inspection, dreaming, and compaction, which is a coherent lifecycle. Minor gaps remain around explicit memory editing or targeted deletion/forgetting, but the system's design suggests decay and compression handle removal indirectly.
