By name: nushell-orchestrator description: Specialized for Nushell scripting, configuration management, and shell automation. Use when the user needs to modify nushell/config.nu, nushell/env.nu, create helper scripts in helpers/*.nu, or automate tasks using Nushell's structured data and pipeline features.
Nushell Orchestrator
Overview
This skill provides expertise in Nushell (nu), a modern shell with a structured data approach. It focuses on maintaining the user's Nushell environment and creating robust, type-safe scripts for system automation.
Core Capabilities
1. Configuration Management
Manage the core Nushell configuration files located in ~/dev/dotfiles/nushell/.
config.nu: Main configuration, aliases, and hooks.env.nu: Environment variables and path setup.linux.nu,macos.nu,windows.nu: Platform-specific overrides.
2. Scripting & Automation
Create and maintain helper scripts in ~/dev/dotfiles/helpers/ (e.g., liquidcfg.nu, wow.nu, setup-aoc-recording.nu).
- Use Nushell's strong typing for script parameters (
def main [arg: string, --flag: int]). - Leverage structured data (JSON, YAML, TOML) parsing and generation.
- Utilize external commands safely using Nushell's
^prefix orrun-external.
3. Dotfiles Installation
Maintain install.nu in the root directory, which handles symlinking and environment setup across different platforms.
Guidelines
- Prefer Tables: Use Nushell's built-in table manipulation (
where,sort-by,select,get) instead ofgrep,sed, orawk. - Type Safety: Always define types for function parameters and return values in scripts.
- Error Handling: Use
try { ... } catch { ... }blocks for fragile operations like network requests or file system changes. - Completions: Implement custom completions for scripts to improve the CLI experience.
Examples
- "Add an alias to my nushell config to list files by size."
- "Create a Nushell script in helpers/ to automate my liquidctl profile switching."
- "Update install.nu to support a new configuration directory."
