What
A plugin is an add-on package that brings extra skills, commands or other features into Claude Code. When you install one from the command line with claude plugin install, Claude Code now passes a "replace" choice to the installer. That choice tells the installer whether to replace a copy of the plugin that is already installed. This step was not part of the install path before.
Why
This may let a plugin install overwrite a copy that was installed earlier, possibly one that came from a different marketplace (a catalogue that plugins are installed from).

* **Project scope**: the plugin is enabled for everyone who works in this repository. The entry goes in `.claude/settings.json`, which you commit. Committing that entry turns the plugin on for your collaborators but doesn't download it to …plugins/install see the edit
