SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill provides a Python-based calculator to safely evaluate mathematical expressions, enabling Claude Code to perform quick, accurate arithmetic without manual computation.

Core Features & Use Cases

Safe Evaluation: Evaluates expressions using a restricted Python namespace to prevent arbitrary code execution.
Supported Operations: Addition, subtraction, multiplication, division, exponentiation, square roots, and constants like pi and e.
Use Case: When a user asks for a calculation such as "123 * 456", Claude Code can compute the result and present it clearly.

Quick Start

Run: python3/scripts/calculate.py "5 * 5" Run: python3/scripts/calculate.py "100 / 4 + 2" Run: python3/scripts/calculate.py "sqrt(25) + 10"
