What

PreToolUse hooks (which run before a tool call executes and can block it) can return permissionDecision=defer. Warnings shown when this happens in interactive mode, or when multiple tool calls are batched together, now identify the tool using a generic classifier rather than printing its raw name.

Why

This keeps the warning informative without exposing the literal tool name, consistent with similar changes to other tool-related log messages.
