collaborativePlanning

Enables human-in-the-loop planning for the Deep Research agent. If set to true, the Deep Research agent will provide a research plan in its response. The agent will then proceed only if the user confirms the plan in the next turn.

Sets Builder.collaborativePlanning to an arbitrary JSON value.

You should usually call Builder.collaborativePlanning with a well-typed Boolean value instead. This method is primarily for setting the field to an undocumented or not yet supported value.
