Each tool maps to a distinct memory operation: inspection (stats), retrieval (search), and storage (write). There is no plausible way to confuse them, and the descriptions reinforce the boundary between reading and writing.

All three names follow the identical memory_<verb> pattern (memory_stats, memory_search, memory_write), with short, predictable verbs. Naming is fully consistent and self-documenting.

Three tools is a tight, well-scoped surface for a memory service where each tool clearly earns its place. It sits at the thin edge of the ideal range, though the narrow scope justifies it.

Read (search), write, and introspection (stats) are covered, but there is no way to delete, correct, or update a stored memory, and stats gives only counts rather than per-collection detail. Agents that wrote a wrong or stale fact have no lifecycle operation to fix it, which is a notable gap for a shared memory store.
