What

When Claude Code packages up the options for a session to hand them on, it now includes two more when set:

  • max_turns, the limit on how many turns Claude may take
  • builtin_tools, the list of built-in tools allowed

Before, only the custom system prompt, spending limit, and allowed and disallowed tool lists were passed along.

Why

A turn limit or a built-in tool list you set can now reach the other side, instead of being dropped.
