Unclear Whether this changes how any permission rule is matched is not known.

What

Permission rules tell Claude Code which actions it may take without asking. The part of Claude Code that reads rules whose content starts with ! has been split in two: one part now returns the rule's content for certain tools, and a separate part does the check for a leading !. This looks like a reorganisation.

Why

It touches how permission rules are matched.
