Each tool targets a distinct action on memory facts: search reads, assert creates, retract tombstones, audit reports quality, correct applies natural-language fixes. The only mild overlap is between memory_correct and memory_retract, since a natural-language correction may imply a retraction, but the descriptions distinguish them (NL correction vs. explicit tombstone).

All five tools use a consistent memory_verb snake_case pattern with clear, distinct verbs. No mixing of conventions or verb styles.

Five tools is well-scoped for a memory/fact-management server, covering the essential lifecycle operations without redundancy or bloat. Each tool earns its place.

The surface covers create (assert), read (search), update/delete (correct, retract), and quality (audit), which is solid lifecycle coverage. A direct fetch-by-id or explicit fact update tool is missing, though assert returning an id partially mitigates this.
