Single tool with clear naming (current_time), good description (127 chars, within 10-1024 range), and well-documented output schema via CurrentTimeResponse struct with 8 typed fields. Input schema is empty (no parameters required), which is appropriate for a stateless read-only operation. Tool follows verb_noun convention and clearly states its purpose. No parameter descriptions needed since there are no parameters. Output fields are well-annotated with doc comments explaining each field's format and meaning. Lacks error handling guidance and tool annotations (readOnlyHint), but these are minor gaps for a simple utility tool.

• Add readOnlyHint annotation to current_time tool to explicitly signal it has no side effects and is safe to call repeatedly.
• Enhance tool description to mention timezone handling and note that it returns local system time (not user-configurable timezone).
• Add error handling documentation: explain what happens if system time is unavailable or timezone lookup fails, and suggest fallback behavior.
• Consider adding an optional parameter to allow requesting time in a specific timezone (e.g., timezone_name: String) to increase utility.
• Migrate from STDIO to HTTP+SSE or Streamable HTTP transport for remote accessibility and hosted client compatibility.

Inferred effective spec: <=2025-11-25.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
