What's Wrong?

I have a plugin installed with a skill named 'memory'. So it's visible in Claude Code as '/plugin_name:memory'. This prevents the built-in command '/memory' from running.
When I type and send '/memory' to Claude Code, it immediately get's replaced by the '/plugin_name:memory' skill invocation. See video for a demonstration.

What Should Happen?

The built-in '/memory' should be invoked
