Comprehensive development toolkit for architecting robust, well-documented Nushell scripts, commands, modules, overlays, and pipelines. Integrates with nu --lsp, nu --mcp, and nu-lint for professional Nushell development.
This skill should be used when the user asks to "build a CLI tool", "create command-line interface", "CLI best practices", "clig.dev guidelines", "help text patterns", "CLI arguments", "CLI error messages", "CLI output formatting", "human-first design", "CLI interactivity", "exit codes", "CLI configuration", "environment variables", or mentions building user-facing Nushell scripts, commands, or tools that should follow professional CLI design principles.
