What
claude plugin install in replace mode can now stop with the failure code "replace_unavailable".
More refusal codes exist for switching a plugin from one marketplace (a source you install plugins from) to another, such as "replace_needs_fresh_listing" and "invalid_plugin_id". Most of that switching path is switched off in this build, so you are unlikely to see them.
Why
This looks like groundwork for moving an installed plugin between marketplaces.

* **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
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
