Scored across 3 tools
The three tools have completely distinct purposes: health handles readiness checks, memory.search is read-only retrieval, and memory.write is state-changing persistence. Their descriptions explicitly cross-reference each other to prevent confusion.
memory.search and memory.write follow a consistent memory.<verb> pattern, but health is a standalone noun not following the same convention. Minor deviation, still readable.
Three tools is within the ideal 3-15 range and each tool serves a distinct, necessary purpose (health, retrieval, persistence). The scope is tightly focused with no redundancy.
Core read/write operations are covered along with a health check. Missing operations like delete or list all might be absent, but search and write cover the primary memory lifecycle without clear dead ends.
