SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Multi-platform development reduces failures caused by operating-system differences, so your project runs reliably on Windows, Linux, and macOS.

Core Features & Use Cases

  • Platform detection: Identify OS at runtime using Node.js, Python, Shell, or PowerShell patterns to choose correct behaviors.
  • Cross-platform implementation guidance: Avoid hardcoded paths and OS-specific assumptions by using portable path handling, shell commands, and environment variable conventions.
  • Compatibility hardening: Normalize line endings, handle file permissions safely, select appropriate package managers, and validate with cross-platform CI/CD and tests.

Quick Start

Use this skill to make sure your script and project work correctly on Windows, Linux, and macOS by asking: "Explain how to write cross-platform commands and path handling for my Node.js + shell setup, including line endings and a GitHub Actions matrix for testing."

Frequently Asked Questions about multi-platform-dev

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I make my shell scripts run on Windows, Linux, and macOS?▼

Cross-platform shell scripts require detecting the operating system at runtime and using portable path handling. You must avoid hardcoded OS assumptions by implementing platform conditionals that select correct behaviors and commands for Windows, Linux, and macOS.

Why do file permissions and line endings break my code on different operating systems?▼

Cross-platform compatibility breaks because operating systems handle line endings and file permissions differently. Normalizing Git line endings and handling file permissions safely prevents execution failures and unexpected formatting changes across Windows, Linux, and macOS environments.

What is the best way to detect the OS at runtime in Node.js or Python?▼

Platform detection identifies the OS at runtime using Node.js, Python, Shell, or PowerShell patterns. This allows your application to choose correct behaviors dynamically rather than relying on hardcoded paths or OS-specific assumptions that fail on other systems.

How do I set up a CI/CD matrix build for testing across Windows, Linux, and macOS?▼

Cross-platform CI/CD matrix builds structure tests across operating systems with appropriate skips and fallbacks. You configure matrix builds to validate platform-aware tests, ensuring your project runs reliably on Windows, Linux, and macOS without platform-specific failures.

How do I handle dependency installation across different package managers for multiple platforms?▼

Cross-platform dependency installation selects appropriate package managers based on runtime environment detection. You implement platform conditionals to choose correct installation commands, ensuring dependencies install correctly across Windows, Linux, and macOS package managers.
