Scored across 4 tools
Each tool performs a unique arithmetic operation (addition, subtraction, multiplication, division) with no overlap. The distinct mathematical symbols in descriptions remove any ambiguity.
All tool names follow the same verb pattern using the operation name (add, subtract, multiply, divide). This is perfectly consistent and predictable.
Four tools is an ideal scope for a basic calculator server, covering the core arithmetic operations without unnecessary bloat.
The four basic operations cover the primary use case for a calculator. A modulo or power operation could be added, but the surface is not severely incomplete.
