Ever since Opus 4.7, the model has been tuned to emit such complex commands that not only a human can’t reasonably review them in reasonable time, even a fairly sophisticated command approval framework I built over time that broke down shell commands/scripts into separately approvable/whitelistable units—with its own mini DSL—got completely lost; it worked great up to Opus 4.6.

So not surprisingly, auto mode is the only sane way to use Opus 4.7+.
