Nushell Pro
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.

Files
Nushell Pro
Write secure, idiomatic, portable, and testable Nushell. Keep the main workflow in this file; load detailed references only when the task needs them.
Operating Workflow
-
Identify the task: new script, debugging, review, refactor, module design, migration, performance work, security audit, or Bash conversion.
-
Read the target
.nufiles, nearby tests,AGENTS.md, and existing project conventions before changing code. -
Establish both the project's supported Nu range (from CI, documentation, or project configuration) and the active local version. Do not assume the local binary defines the compatibility target. Prefer the official English docs; translations can lag. When local docs/source checkouts are available, inspect them and record their revision separately from the installed Nu version. From any shell, prefer:
nu --versionWhen already inside Nushell or when structured version data is needed, use:
version | get version -
