A standalone Node.js module that intelligently detects available package managers (npm, pnpm, yarn, bun) with configurable priority. It exposes a single async function that returns the first available manager from the priority list, or falls back to a default. The implementation is self-contained, uses spawnSync for detection, and handles Windows/Unix differences. This component can be extracted and reused in any project that needs to programmatically select a package manager for running scripts or installing dependencies.

A collection of cross-platform Python utility functions for common operations: file reading/writing, command existence checking, git detection, directory creation, and environment variable handling. Each function is self-contained with proper error handling and platform detection (Windows vs Unix). This module can be extracted and reused as a foundational utility library in any Python project that needs reliable cross-platform file and system operations without external dependencies.

A Python script that verifies academic citations by querying multiple APIs (CrossRef, arXiv, Semantic Scholar) and performing format checks and content matching. It implements a multi-layer verification pipeline: format validation, existence check across APIs, information matching, and confidence scoring. The script is parameterized, handles API rate limiting, and produces structured output. It could be extracted as a standalone citation verification tool or integrated into other research workflow automation systems.
