The Current DateTime server has a single tool with extremely minimal definition. The tool name 'current-datetime' lacks a leading action verb (should be 'get_current_datetime' per verb_noun convention). The description is only 18 characters ('Get Current Date/Time'), below the 20-character minimum for actionable descriptions. Most critically, the input schema is completely empty ({}), providing zero guidance to LLMs about what parameters are accepted. There are no parameter descriptions, no output schema documentation, no error handling guidance, and no validation. The tool is functional but fails to meet baseline production quality standards for agentic tool patterns.

• Rename tool from 'current-datetime' to 'get_current_datetime' to follow verb_noun convention and help LLMs identify the action immediately.
• Expand description to 50-150 characters: 'Retrieves the current date and time. Returns ISO 8601 formatted timestamp. Call this whenever you need to know the present moment.' Include what the output format is and when to use it.
• Add explicit input schema definition. Even though the tool takes no parameters, document this clearly: inputSchema: { type: 'object', properties: {}, required: [] }. This tells LLMs 'this tool accepts no input'.
• Document the output schema in the tool registration or in the description. Specify: returns object with 'timestamp' field (string, ISO 8601 format) or clarify that it returns a raw Date.toString() result. LLMs need to know what fields to expect.
• Add error handling for edge cases: set a timeout (e.g., 5 seconds), handle system clock errors gracefully, return structured error responses with recovery hints (e.g., 'System time unavailable. Check system clock configuration.').
