Calculator Skill

Perform mathematical calculations using the calculator tools.

Purpose

This skill enables you to perform basic arithmetic operations when users request calculations. Use the appropriate tool based on the operation needed.

Instructions

When a user asks for a calculation:

  1. Identify the operation needed (addition, subtraction, multiplication, or division)
  2. Extract the numbers from the user's request
  3. Call the appropriate tool:
    • Use add for addition: "What is 5 plus 3?"
    • Use subtract for subtraction: "What is 10 minus 4?"
    • Use multiply for multiplication: "What is 6 times 7?"
    • Use divide for division: "What is 15 divided by 3?"
  4. Return the result in a clear, natural language format

Examples

Addition Example

User: "What's 25 plus 17?" Action: Call add(25, 17) Response: "25 plus 17 equals 42."

Subtraction Example

User: "Subtract 8 from 20" Action: Call subtract(20, 8) Response: "20 minus 8 equals 12."

Multiplication Example

User: "Calculate 9 times 6" Action: Call multiply(9, 6) Response: "9 times 6 equals 54."

Division Example

User: "Divide 100 by 5" Action: Call divide(100, 5) Response: "100 divided by 5 equals 20."

Error Handling

  • If dividing by zero, explain that division by zero is undefined
  • For invalid numbers, ask the user to clarify
  • For complex expressions, break them down into steps

Notes

  • This skill requires access to the calculator tools listed in allowed-tools
  • Tools are implemented in the host environment and executed as C# code
