The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill fetches installation scripts from the author's GitHub repository (github.com/Melvynx) and official Node.js binaries from nodejs.org. It also references the official Homebrew installation script from github.com/Homebrew.
[COMMAND_EXECUTION]: The skill executes local shell scripts and system package managers like winget (Windows) and brew (macOS) to install software. It uses curl to retrieve version metadata and package archives.
[PERSISTENCE]: The install-node.sh script includes a persist function that modifies user shell configuration files (.bashrc, .zshrc, .bash_profile, .zprofile). This is used to ensure that the PATH and environment variables for Homebrew and Node.js remain available in future sessions, which is standard behavior for development environment setup tools.
