What
A tool call is a single action Claude takes, such as running a command. A turn is one round of you sending a message and Claude responding. The check that decides whether a tool call is denied, or whether the run is stopped altogether, now records the turn number with each decision.
Why
In practice, repeated denials may now be counted with the turn they happened on, rather than across the whole run.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
