Nushell Pro

Summary

This is a comprehensive style guide and security checklist for Nushell scripting, covering everything from pipeline semantics to type signatures to parallel execution patterns. Use it when you're writing .nu files from scratch, converting Bash scripts to idiomatic Nushell, or reviewing code for security issues like untrusted input handling and destructive operations. The workflow is methodical: it walks you through identifying your task type, loading only the relevant reference sections (string handling, security, dataframes, anti-patterns), then applying validation checks before execution. The real value is in the critical distinctions it enforces, like pipeline input versus parameters, immutability defaults, and structured data over string parsing. Good for teams standardizing on Nushell or anyone tired of fighting the parser.
