Calculator

Calculator

Perform mathematical calculations with precision. Use this skill for ANY numerical calculations — never do mental math.

Usage

Run the bundled script with JSON operations:

bun .cursor/skills/calculator/scripts/cli.ts '<json_operations>'

Input Format

Pass a JSON array of operations, where each operation has:

• operator: One of add, subtract, multiply, divide
• operands: Array of numbers (minimum 2)

Examples

Single calculation:

bun .cursor/skills/calculator/scripts/calculator.ts '[{"operator":"add","operands":[1,2,3]}]'

Multiple calculations (batched):

bun .cursor/skills/calculator/scripts/calculator.ts '[{"operator":"add","operands":[10,20]},{"operator":"multiply","operands":[5,6,2]},{"operator":"divide","operands":[100,4]}]'

Output

Returns JSON with results for each operation:

{
  "results": [
    { "operation": "add(10, 20)", "result": 30 },
    { "operation": "multiply(5, 6, 2)", "result": 60 },
    { "operation": "divide(100, 4)", "result": 25 }
  ]
}

When to Use

• Always for any numerical calculation, no matter how simple
• Percentage calculations
• Unit conversions
• Aggregating numbers
• Any math where precision matters
