One cask, for ccwidget — a macOS desktop widget showing how much of a Claude Code subscription has been spent.
brew install --cask illvminat/tap/ccwidgetUninstalling undoes the configuration as well as removing the app: the widget
writes an exporter into ~/.claude and points the Claude Code statusLine at
it, and a cask that deleted only the bundle would leave that line running a file
that no longer exists.
brew uninstall --cask ccwidget # app and configuration
brew uninstall --zap --cask ccwidget # and the collected history
