Auto-mode's safety classifier gained a new 'arbiter' mode that can skip some server checks
A new internal dispatcher for Claude Code's Bash and tool auto-mode classifier (the system that automatically decides whether a command is safe to run without asking) can now return "arbiter" as a mode, in addition to "off", depending on two remote feature checks. When arbiter mode is active, tool calls run through a fallback classifier evaluation path that skips redundant server calls and can reach a decision before the normal checks that gate auto mode, such as the outside-read-first-prompt and sandbox network list checks.
This changes how and when auto-mode's safety classification happens for some accounts, potentially making decisions faster by avoiding duplicate server round-trips, though it isn't yet clear for whom or when this activates.
