Scored across 4 tools
Each tool performs a single, distinct arithmetic operation with no overlap. An agent can easily select the correct tool based on the desired operation.
All tool names follow a consistent lowercase verb pattern: add, subtract, multiply, divide. The naming is predictable and uniform.
Four tools is an ideal scope for a basic calculator server. Each tool covers a fundamental operation without unnecessary bloat.
The four basic arithmetic operations are fully covered, which satisfies the core purpose. Minor gaps like modulo or exponentiation exist but are not essential for a simple calculator.
