What's Wrong?

When I enter /review, I get something like:

I see you're trying to use the /review command. This command has been moved to a plugin system.

To use code review functionality, you'll need to:

1. Install the plugin:

claude plugin install code-review@claude-code-marketplace

1. Run the code review:

After installation, use /code-review:code-review to perform code reviews

1. Learn more:

See the documentation at: https://github.com/anthropics/claude-code-marketplace/blob/main/plugins/code-review/README.md

What Should Happen?

It should carry out a review based on the builtin review slash command just like it has in previous version.
