What
The check that spots the API rejecting the setting for how thinking is displayed was moved into a shared, prepared pattern. Separately, tool results coming from worker or remote agents are now processed before Claude Code passes them on.
Why
This may change how Claude Code retries after that error and what tool results look like to programs using Claude Code through its SDK.
