This might be the expected behavior, but I was trying to update npm:@zed-industries/claude-agent-acp just now and it was only finding verison 0.21.0 even though 0.22.2 is out.

I kinda assumed that upgrade would bypass the the prefer_offline since it kinda requires doing online stuff, no?

Here's some out put from when I was debugging.

(☸|kind-timescape) ~/.dotfiles ❯ mise latest npm:@zed-industries/claude-agent-acp --debug                                                                                                                master ✱ ⬆ 6

  '0.20.2', '0.21.0',
  '0.22.0', '0.22.1',
  '0.22.2'
]

Then I commented out prefer_offline = true and lockfile = true in my config.toml and re-ran mise latest:

(☸|kind-timescape) ~/.dotfiles ❯ mise latest npm:@zed-industries/claude-agent-acp --debug                                                                                                                master ✱ ⬆ 6

As documented at prefer_offline this is applied to "fast" commands and was mainly introduced to avoid the (slow) version lookup use-case.

yeah I think this is working as expected

Is upgrade considered a "fast" command though? That's what gets me, feels a bit off to have upgrade upgrade to not latest versions, even with the option.

it's not considered fast

So by that logic, shouldn't upgrade bypass prefer_offline if possible?
