This is a good sign that it's time to get packages off of NPM and come up with an alternative. For those who haven't heard of or tried Verdaccio [1], it may be an option. Relatively easy to point at your own server via NPM once you set it up.

I've had decent luck running it locally, but claude keeps screwing up the cool-down settings in my monorepo.

This is probably a common problem. Has anyone gotten verdaccio to enforce cool-down policies?

I also waste a ton of time because post-install scripts are disabled. Being able to cut them off from network access, and just run a local server with 2-4 week cool-down would help me sleep better at night + simplify the hell out of my build.
