Each tool has a distinct role: remember writes, recall searches, brief returns a curated wake-up subset, tick runs maintenance, stats reports metrics. The only mild overlap is between recall and brief (both return memories), but the descriptions clearly separate query-driven retrieval from a fixed high-importance digest.

All five names are short, lowercase, single-word tokens with no mixed casing or prefix conventions. There is a slight verb/noun mix (remember/recall/tick vs. brief/stats), but the style is uniform and readable.

Five tools cleanly cover the memory lifecycle: write, retrieve, digest, maintain, and measure. Nothing feels redundant and no operation is split into artificial variants.

The core write/read/maintenance loop is covered, but there is no way to update or delete a specific memory — errors can only be corrected by writing a new memory or waiting for tick decay. This append-only design is plausible but leaves notable gaps for agents needing correction or targeted removal.
