MemAuthority has 16 tools with reasonable naming (verb_noun pattern) and descriptions present for all. However, critical gaps undermine quality: most tools lack visible input schemas in the source code, only RouteArgs is explicitly defined. Parameter descriptions exist in struct tags but are not formally validated against JSON Schema. Output schemas are entirely undocumented. Error handling is absent from tool definitions. The server conflates read-only and destructive operations without clear guidance on idempotency or retry safety. STDIO transport caps protocol readiness at 50, further limiting production viability.

• Define explicit JSON Schema for all 16 tools' input parameters. Use jsonschema struct tags consistently (as done for RouteArgs) and validate against go-sdk's schema registration. Include type, description, enum constraints, and min/max for all parameters.
• Document output schemas for every tool. Specify returned fields, types (string, number, array, object), and structure. For list tools (memory_search), include pagination fields (total_count, next_cursor) and per-item structure.
• Add error handling guidance to tool descriptions. For DESTRUCTIVE tools, state: 'This operation is irreversible. Provide expected_resource_revision to detect conflicts. Returns error if revision mismatch.' For WRITE tools, clarify retry safety via idempotency_key.
• Expand idempotency_key parameter description to: 'UUID or unique string to prevent duplicate operations if the request is retried. Same key + same parameters = idempotent; omitting this key risks duplicate writes on network failures.'
• Add composition hints to tool descriptions. E.g., memory_route returns project_id; memory_read accepts uri; memory_search returns uris. Document which tools chain together so LLMs can plan multi-step workflows without discovery detours.
