26 tools with mostly complete schemas and descriptions, but significant gaps in error handling, parameter validation, and output documentation. Tool names follow verb_noun convention well (memory_store, memory_recall, reminder_set). Descriptions average ~80 chars, below the 194-char baseline for A+ tools. Input schemas present for all tools with proper enums (memory types, tiers, roles), but output schemas are undocumented. No error recovery guidance, no confirmation patterns for destructive ops (memory_forget, admin_reset), and no rate limiting or permission gates visible. Security concern: admin_reset accepts a boolean confirm parameter but lacks multi-factor confirmation or audit logging.

• Document output schemas for all 26 tools. Specify returned fields (e.g., memory_store returns {id, created_at, tier}), types, and which fields enable chaining (e.g., memory_id for memory_patch).
• Add confirmation patterns to destructive tools: memory_forget and admin_reset should require a second confirmation step or return a confirmation_token that must be passed in a follow-up call.
• Add min/max bounds to numeric parameters: limit (1 - 100), depth (1 - 5), version (0 - N). State these in parameter descriptions so LLMs understand constraints.
• Implement permission gates: gate admin_reset and admin_export behind a 'require_admin_role' check. Return 'Permission denied: admin role required' with clear guidance.
• Add error recovery hints to tool descriptions: 'If memory not found, try memory_search() with a partial query.' This guides LLM retry logic per pattern:recovery-guide.
