TDQS
Scored across 2 tools
The two tools, 'calculate' and 'convert_temperature', have clearly distinct purposes with no overlap. An agent can easily select the appropriate tool based on the task.
Both tool names follow a consistent verb_noun pattern: 'calculate' (verb) and 'convert_temperature' (verb_noun). The naming is predictable and clear.
With only 2 tools, the set is minimal but still reasonable for a focused calculator server. It covers core arithmetic calculation and temperature conversion without unnecessary clutter.
The tool surface covers basic arithmetic and temperature conversion, but lacks other common calculator operations like exponentiation, trigonometry, or memory functions, leaving notable gaps for a general-purpose calculator.
