New Features verbatim_prompts option : Added ClaudeAgentOptions.verbatim_prompts (default False ).

This prevents untrusted text inlined into prompts from triggering unintended file reads or command execution.
Claude Agent SDK 0.2.160

Follow-up turns would then fail with "Stream closed" and the model would report the tool as refused.
