Scored across 6 tools
Each tool performs a unique mathematical operation (add, subtract, multiply, divide, power, square root) with no overlap.
All tool names are single-word or underscore-separated (e.g., square_root), using consistent imperative verbs.
Six tools cover essential arithmetic plus power and square root, appropriate for a basic calculator.
Covers addition, subtraction, multiplication, division, exponentiation, and square root. Missing common operations like modulus or floor division, but reasonable for a simple calculator.
