Calculator tool for the Laravel AI SDK

Part of the shipfastlabs/toolkit catalog of reusable AI tools for the Laravel AI SDK.

Installation

composer require shipfastlabs/toolkit-calculator

Usage

Instantiate the tool and pass it to an agent's tools():

use Shipfastlabs\Toolkit\Calculator\CalculatorTool;

$tools = [new CalculatorTool];

Input schema

Supports +, -, *, /, %, ^ (exponent, right-associative), parentheses, unary +/- and decimal numbers.

Configuration

None. The calculator is pure and ships no config or service provider.

Safety

The expression is parsed by a small recursive-descent evaluator; PHP's eval() is never used. Invalid input, division or modulo by zero, and non-finite results are returned to the model as plain strings rather than thrown, so the model can recover.
