For an instance, I have a "busybox" npm package in my local npm repository

To deprecate an entire package, run the following command, replacing <package-name> with the name of your package, and "<message>" with your deprecation message:
npm deprecate <package-name> "<message>"
Deprecated the busybox package:

Then the deprecation message will be added in the properties tab

Once the property is set, the corresponding installation requests for the busybox local package should display the deprecation message.
