Four tools with complete descriptions and basic schemas. Naming follows verb_noun convention (create_, search_, get_). Descriptions are substantive (150-250 chars), exceeding the 10-char minimum but below the 1024-char cap. All tools have input schemas with type declarations. However, output schemas are not formally documented, responses are inferred from code (text content + isError flag). Parameter descriptions are present but lack constraint details (ranges, enums, format specs). No error recovery guidance or actionable error messages. Missing tool annotations (readOnlyHint, destructiveHint). create_memory is a write operation but lacks confirmation or dry-run pattern.

• Document output schemas formally. Define the response structure for each tool: e.g., create_memory returns {memory_id: number, created_at: string}, search_memories returns {memories: [{id, content, created_at}], total_count: number}.
• Add numeric constraints to parameter descriptions. E.g., 'days' → 'Number of days to include (1 - 365, default 30)'; 'range' → 'Number of surrounding memories (1 - 50, default 5)'; 'content' → 'Memory text (1 - 10000 characters)'.
• Add tool annotations via the MCP SDK. Mark create_memory with destructiveHint=true; mark search_memories, get_memory_context, get_memory_stats with readOnlyHint=true.
• Enhance error messages with recovery guidance. E.g., 'Memory ID 999 not found. Try search_memories() to find existing memory IDs.' Classify errors as retryable (network timeout) vs user-fixable (invalid ID).
• Consider adding a confirm_create_memory tool or a dry_run parameter to create_memory to prevent accidental writes by agents.
