What
Before Claude Code runs a tool (an action such as editing a file or running a command), a permission check decides whether to allow it, deny it, or ask you. A new pre-check can now change an allow into an ask. The recorded reason then includes reroutedFrom and replaces.
This applies only when the call is not a servedCall and the current permission mode passes a check.
Why
In practice, some actions that would have gone through automatically can now stop and ask for your approval.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what a `servedCall` is or which permission modes the check lets through.
