SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables safe arithmetic calculations by using Python's operator module instead of eval or exec, preventing code execution risks when handling user-provided expressions.

Core Features & Use Cases

  • Safe arithmetic with standard operators (+, -, *, /) using the operator module.
  • Input validation to ensure numeric operands are provided.
  • Use Case: Integrate into chat agents to perform quick, reliable calculations for user queries without executing arbitrary code.

Quick Start

Use the simple-math skill to calculate 25 + 17. The result is 42.

FAQPage Schema
How do I perform safe arithmetic calculations in Python without using eval?

Safe arithmetic calculations in Python can be performed using the operator module instead of eval. This approach validates numeric operands and applies standard operators like addition and subtraction without executing arbitrary code.

Why should I avoid eval for math operations with user inputs?

You should avoid eval for math operations because it executes arbitrary code, creating severe security risks. Using the operator module ensures numeric operands are validated and only standard arithmetic operations are performed safely.

Can I use Python's operator module for interactive agent math workflows?

Yes, the Python operator module works for interactive agent math workflows. It applies to automation tasks and chat agents by providing reliable calculations for user queries while ensuring inputs are strictly validated as numeric operands.

What is the best way to calculate user-provided expressions safely in an automation script?

The best way to calculate user-provided expressions safely is using the operator module for basic math. This prevents code execution risks by validating operands and performing operations directly rather than evaluating strings dynamically.

Are there limitations to calculating math expressions without eval or exec?

Calculating math expressions without eval or exec limits operations to basic arithmetic with standard operators like addition and division. Complex expression parsing or non-numeric operand handling is not supported, ensuring strict safety and validation.
