MemPalace has 8 tools with basic naming and descriptions, but significant gaps in schema completeness and parameter documentation. Tool names follow verb_noun convention (mempalace_list_*, mempalace_search, mempalace_add_drawer, mempalace_delete_drawer), which is good. However, descriptions are terse (10-50 chars), parameter descriptions are minimal or absent, and output schemas are not documented. The server lacks error handling guidance, confirmation patterns for destructive operations, and input validation documentation. No tool annotations (readOnlyHint/destructiveHint) despite clear risk levels. Schemas visible for 5/8 tools but incomplete, many parameters lack descriptions. This is typical community-server quality: functional but not production-ready.

• Document output schemas for all tools. E.g., mempalace_search should return [{drawer_id, content_preview, wing, room, similarity_score}] so agents know what fields to extract for downstream calls.
• Expand descriptions to 50 - 200 chars with WHAT/WHEN/PREREQUISITES. E.g., 'List all wings and their drawer counts. Call this first to explore palace structure before searching or filing.' instead of 'all wings with drawer counts'.
• Add tool annotations: readOnlyHint=true for read tools (mempalace_status, mempalace_list_*, mempalace_search, mempalace_check_duplicate); destructiveHint=true for mempalace_delete_drawer; idempotentHint=true for mempalace_add_drawer if it deduplicates.
• Add parameter descriptions with constraints. E.g., 'limit: max results to return (1 - 1000, default 20)' and 'wing: wing name (string, case-sensitive, e.g. "main_wing")'. Document mutually exclusive params if any.
• Implement confirmation pattern for mempalace_delete_drawer: add optional 'confirm=true' parameter and return 'Drawer deletion requires confirmation. Call again with confirm=true to proceed.' on first call.
