Single tool with minimal definition quality. Tool name 'generate_uuid_v4' follows verb_noun convention (+), but description is extremely terse (27 chars, well below 50-200 char baseline for LLM-optimized descriptions). Input schema is present but empty (no parameters needed), which is correct for this tool's purpose. No output schema documented. No error handling guidance. No parameter descriptions (N/A here). Tool is trivial but definition lacks production-grade polish.

• Expand tool description to 80-150 chars. Example: 'Generate a cryptographically random UUID v4 (RFC 4122). Returns a string in standard format: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx. Useful for creating unique identifiers, session tokens, or request IDs.'
• Document output schema in tool metadata or response. Specify: returns object with 'uuid' field (string, format: uuid) or just a plain string UUID.
• Add explicit error handling for edge cases (e.g., if uuid library fails). Return structured error with recovery hint: 'UUID generation failed. This is a system error, retry the request.'
• Consider HTTP+SSE or Streamable HTTP transport for remote accessibility and production deployment.
• Add tool annotation hints if applicable (e.g., readOnlyHint: true, idempotentHint: true) to signal to clients that this tool is safe to call repeatedly.
