Single tool 'getStringLength' has a basic but incomplete definition. Tool name lacks action verb clarity (should be 'get_string_length' per convention). Description is minimal (24 chars, below 50-char baseline for A+ tools). Input schema is present with type and description, but output schema is undocumented, LLMs cannot predict return structure. No error handling guidance, no parameter constraints, no composition hints. Tool is trivial (string length calculation) and does not demonstrate production-grade patterns.

• Rename tool to 'get_string_length' (snake_case) and update handler registration to match MCP naming conventions.
• Expand description to 80 - 150 characters: 'Returns the number of characters in the input string, correctly handling multi-byte Unicode. Useful for validating string length constraints or measuring text size.'
• Document output schema explicitly in code comments and tool metadata: 'Output: {content: [{type: "text", text: string}], isError: boolean}'.
• Add input validation and error handling: reject null/undefined inputs with message 'Input must be a non-empty string', handle very long strings gracefully (cap at 1M chars with warning).
• Migrate from STDIO to HTTP+SSE or Streamable HTTP transport to enable remote client access and production deployment.
