What's Wrong?

When I try and use the plugin "Ui ux pro max" in Claude Code it doesn't pick it up. But when I switch to Claude's normal chat, It picks it up right away.

What Should Happen?

What should happen is when I type in / I should see /ui-ux-pro-max pop up in my command list so i can use it in my coding.
