Critical failures across all dimensions. Tools have descriptions but lack input schemas entirely (empty {} objects). No parameter descriptions, no output schema documentation, no error handling guidance. Duplicate tool registration (SystemInfo appears twice). Tool names lack action verbs (CurrentDateAndTime, SystemInfo are nouns/adjectives, not verb_noun pattern). Descriptions are generic and under 50 chars on average. No validation, no pagination support, no structured output guidance. This server fails basic MCP tool definition standards.

• Add Zod schemas to all tools. Define input parameters with types and descriptions: e.g., z.object({ timezone: z.string().describe('IANA timezone name, e.g. America/New_York') }). Currently all tools have empty {} schemas.
• Rename tools to verb_noun pattern: 'CurrentDateAndTime' → 'get_current_date_time', 'SystemInfo' → 'get_system_info'. This matches LLM expectations and the 90% baseline of A+ tools.
• Return structured JSON objects instead of text blobs. E.g., { local_time: string, utc_time: string, timezone: string, timestamp_ms: number, day_of_week: string, day_of_year: number, week_of_year: number } for CurrentDateAndTime. Enables downstream tool chaining.
• Add try-catch blocks with actionable error messages. E.g., 'Failed to determine timezone: Intl.DateTimeFormat not available. Falling back to UTC.' Guides agent recovery.
• Remove duplicate SystemInfo tool registration. Keep only one definition with complete schema and error handling.
