Unclear The name the marketplace entry file must have is not given.
A plugin is an add-on for Claude Code, and a marketplace is a catalogue that describes plugins. Claude Code now reads a marketplace entry file kept inside a plugin's own folder and uses it when it loads the plugin. The file:
- must be a regular file
- must be no larger than 1 MiB
- must be valid JSON in the expected format
If the file breaks these rules, Claude Code shows an error saying the marketplace entry cannot be used and asking you to fix or remove the file.
A plugin that is loaded from a folder can be reloaded each time you save. If that folder has a marketplace entry, the reload on save now stops with an error, because it does not apply the entry. Run /reload-plugins instead.
Plugin authors can describe a plugin from a file inside the plugin's own folder. When that file is present, run /reload-plugins to apply your changes, because reloading on save will not pick them up.
