Plugins can call model.fork to ask a question against the live transcript, with no tools and a two-turn cap.
A new plugin hook-API operation, model.fork, lets a plugin spawn a sub-query that forks the live main-thread transcript instead of starting a fresh agent context. The forked call strips trailing tool_use blocks, disallows tool use entirely (failing with "A model fork cannot use tools"), caps the fork at 2 turns, and reserves a 24000-token budget per call. If there is no warm main-thread transcript to fork from, the operation declines quietly with a debug log rather than throwing an error.
