What
Some plugins (add-on packages that extend Claude Code) are synced from your claude.ai account. When the folder for one of these is no longer on disk, the error now says: "claude.ai syncs this plugin and its directory is no longer on disk; restart Claude Code to refresh your synced plugins". Before, it told you to check the path in your manifest or marketplace config, which did not help for synced plugins.
Results from slash commands (commands you type starting with /) can now also carry which plugin they came from.
Why
The old message pointed at a config file you may never have edited. The new one tells you the actual fix.
