Scored across 6 tools
Each tool has a distinct operation: add, list, remove, search, summary, update. No overlap in functionality.
All tools follow the consistent pattern 'memory_' followed by a verb in imperative form (add, list, remove, search, summary, update).
6 tools cover essential CRUD plus search and summary, appropriate for a memory management server without being excessive.
Covers all basic operations: create, read (list/search), update, delete, plus a summary. No obvious gaps.
