What probably matters to youSection of the release
What
A new function, $.tool.check, is available to plugin scripts (hooks that extend Claude Code's behavior). It takes the same input as an actual tool call, an object of the tool's arguments, and runs it through the same permission pipeline used for real tool calls, but only to ask whether the call would be allowed, without executing it.
Why
Plugins can now confirm a tool call is permitted before triggering it for real, letting them make decisions or ask the user ahead of time instead of finding out only after running the tool.
