What
Before running a shell command, Claude Code tries to work out what it will do so it can apply your permission rules. Some commands run other commands given to them, which makes that check impossible. The reason shown in that case is now shorter:
Before: "'' can run its argument as a command, so what it will run cannot be checked in advance"
Now: "What '' starts can't be checked before it runs"
Separately, when a guard fails to run and blocks the command, the block now carries some extra information. A guard is a hook, a check you configure to run before commands.
Why
These messages appear when Claude Code stops or questions a command, so you will see the new wording.
How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtIt is not clear what extra information is added when a guard that could not run blocks a command.
