What probably matters to youSection of the release
The CLAUDE_CODE_TOASTY_THIMBLE ephemeral-reminder mechanism now has a modelOwn fallback: when neither the env var nor client_data supplies reminder text, it can inject the instruction "First privately list what you need next; then request every item that doesn't depend on another's result in this one response." This only fires for models the model catalog tags with the server-side fable_5_1_prompt_bundle capability flag.
