What
Before, a missing plugin produced a general "not found in marketplace" error with the hint "Plugin may not exist in marketplace". When a plugin has been removed from its marketplace directory, the error now says so, and the suggested fix depends on why:
The listing was renamed: uninstall the plugin, then install it under its new name from /plugin → Discover.
The listing can no longer be installed.
The plugin's identity changed.
The plugin registry could not be read: run /reload-plugins, and if the plugin still does not load, fix or restore installed_plugins.json in the plugins directory.
Errors for a marketplace that failed to load and for a plugin blocked by policy also get messages specific to the directory. An error for a plugin missing from the local cache now points to installed_plugins.json.
Why
If a plugin you use was delisted or renamed, you now get steps you can follow instead of a general not-found message.
