Memory Buddy defines 3 tools with basic schemas and descriptions, but falls short of production quality in multiple dimensions. Tool names use verb_noun pattern correctly (memory_status, memory_search, memory_compact), but descriptions are minimal (34 - 53 chars, below the 50 - 200 char LLM-optimized baseline). Input schemas are present but lack parameter descriptions for critical fields. Output schemas are not documented. No error handling guidance or recovery paths. No tool annotations (readOnlyHint/destructiveHint). Missing pagination for search results. Parameter descriptions are sparse or absent.

• Expand memory_status description to ~100 chars: 'Retrieve memory system statistics: total events stored, number of sessions, last update timestamp, and storage size. Use this to monitor memory health and trigger compaction if needed.'
• Expand memory_search description to ~120 chars: 'Search stored memories by keyword(s). Returns matching events ranked by relevance. Supports pagination (limit 1 - 100, default 20). Use this to retrieve contextually relevant memories before forming responses.'
• Expand memory_compact description to ~90 chars: 'Consolidate and compress the current session\'s memories to reduce storage. Irreversible operation that summarizes events. Run at session end or when storage exceeds thresholds.'
• Add input parameter descriptions: query for memory_search should specify 'Keywords or phrases to search (alphanumeric, spaces, hyphens; max 256 chars). Supports fuzzy matching. Case-insensitive.'
• Document output schemas in code comments and server registration. Example: memory_status returns {version: string, eventsCount: number, sessionsCount: number, lastUpdate: ISO8601 string}.
• Add pagination parameters to memory_search: limit (1 - 100, default 20), offset (0 - N). Return total_count, next_offset in response.
• Add tool annotations to server.ts: mark memory_status and memory_search with readOnlyHint: true in their tool definitions. Mark memory_compact with destructiveHint: true.
• Add error handling guidance: If query is empty, return 'Query cannot be empty. Provide one or more keywords.' If no results found, return 'No memories found matching query. Try broader keywords or search without temporal filters.'
