What
Claude Code can print an error message saying a plugin's hooks run on another machine. Hooks are your own commands that run automatically at set moments. That message used to be written out separately in each place it appeared and is now kept in one place. The logic around it is unchanged.
Why
This should make no difference to what you see or what Claude Code does.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
Whether the wording of the message itself changed was not checked.
