What probably matters to youSection of the release
What

Apps that drive Claude Code through the Agent SDK send requests to change and read its settings.

  • apply_flag_settings: if the request fails, Claude Code now logs it and replies with apply_flag_settings failed. Before, some failures were caught only on a delayed path.
  • advisorModel: flag settings now apply this key, which picks the model that answers when Claude asks the advisor tool.
  • get_settings: the reply now includes details about tool permissions.
  • get_settings: when blockFileToolReadsOutsideWorkingDirectories is true, it now waits for the read limits to be set up before replying.
Why

SDK apps get a clear error instead of silence when applying settings fails. They can also choose the advisor model and see the current permission state.
