What
When Claude Code prepares a request to ask you for permission, it already checked that some fields were text or true/false values. It now also checks other fields, such as permission_suggestions, each with its own rule. Any field that fails its check is dropped.
Why
A badly formed permission request is less likely to cause problems.
