Scored across 43 tools
The tool set has several ambiguous clusters: session_log vs session_save_decision vs event_note, and memory_search vs knowledge_search vs session_search. The loading-cache family (cache_store, cache_get, cache_stats, cache_clear) is redundant, and maintenance/utility tools (maintenance_vacuum, api_analytics) sit awkwardly alongside data tools.
Prefixes are mixed across domains (session_, memory_, knowledge_, cache_, tool_, api_), and some tools use bare verbs (prune_history, follow_up, help) that don't indicate their domain. The verb-noun structure is inconsistent — some use get_/update_/delete_, but others use action_only names like summarize.
43 tools is extreme overkill for a personal memory/assistant server. Clusters like cache_* (5 tools), memory_* (4), session_* (11), and tool_* (6) could each be collapsed into one or two parameterized tools, and the knowledge/session split creates significant redundancy.
The surface covers the core domain broadly — sessions, memory, knowledge, cache, maintenance — but is missing simple primitives like a plain 'save_note' toolholistic entry point. Coverage is scattered and defense-in-depth oriented rather than complete.
