What's Wrong?

superpowers only works in the Claude code desktop app. it does not work in the CLI or the vs code extension. the following error shows in the CLI

Plugin superpowers has an invalid manifest file at
/Users/rob/.claude/plugins/cache/claude-plugins-official/superpowers/4.3.1/.claude-plugin/plugin.json.

Validation errors: : Unrecognized keys: "category", "source"

Please fix the manifest or remove it. The plugin cannot load with an invalid manifest.

What Should Happen?

I should expect that a plugin in install in one place should work in others.
