Two tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names lack action verbs (hello, calculate are generic). Descriptions are present but minimal (34-72 chars, below the 50-200 char LLM-optimized baseline). Parameter descriptions exist but lack format constraints, ranges, and error guidance. No documented output schemas. Error handling is absent. This is a starter template, not production-grade.

• Rename 'hello' → 'greet_user' and 'calculate' → 'perform_math_operation' to follow verb_noun convention and clarify intent.
• Expand descriptions to 100-150 chars: 'Greet a user by name. Returns a friendly greeting message. Use when the user requests a personalized greeting.'
• Add output schema documentation: hello returns {greeting: string}; calculate returns {result: number, operation: string}.
• Add parameter constraints: name (1-100 chars, alphanumeric+spaces); a, b (numbers, -1e6 to 1e6); operation (enum: add|subtract|multiply|divide).
• Document error cases: 'Division by zero returns error code DIV_ZERO with message "Cannot divide by zero. Check parameters a and b."'

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

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