Each tool has a clearly distinct role: remember writes, recall does query-based retrieval, list_memories enumerates all facts, list_entities enumerates people/places, and forget deletes. The recall vs. list_memories boundary (search vs. full listing) is explicitly spelled out in the descriptions, leaving no real overlap.

All names are imperative lowercase verbs, which gives a readable, predictable style. However, the pattern is not strictly verb_noun: remember/recall/forget omit the object while list_memories/list_entities include one, a minor inconsistency but not confusing.

Five tools is well-scoped for a personal memory store: one write, three read shapes, and one delete. Every tool earns its place with no redundant or speculative operations.

The lifecycle is essentially covered: remember implicitly handles updates with history, and forget handles deletion. Minor gaps exist, such as bulk deletion of all of a user's data (beyond one memory at a time) and no way to remove or merge entities explicitly.
