zsh Setup

Configures zsh — macOS's default shell — the modern way: standalone plugins installed via Homebrew (autosuggestions, syntax highlighting), the Starship prompt, and a startup-file structure that stays fast and debuggable. No framework required. This skill owns the structure of ~/.zshrc; other skills append guarded snippets, and ~/.zprofile's brew line belongs to homebrew-setup.

When NOT to use

• Terminal emulator install (Ghostty/iTerm2/Warp) → mac-dev-apps
• CLI tools like fzf/zoxide/eza themselves → dev-cli-tools (their init lines land in .zshrc but tool choice lives there)
• Versioning the config in a repo → dotfiles-setup
• Writing shell scripts → not a setup task
