Converse rejects a request that carries both toolConfig.toolChoice and an
additionalModelRequestFields.tool_choice.type, so any request that pairs
parallel_tool_calls with an explicit tool_choice 400s with "The additional field
tool_choice/type conflicts with the existing field toolConfig.toolChoice.auto".
That pairing is what agentic clients send by default; Codex CLI sends
tool_choice "auto" and parallel_tool_calls false on every turn, so tool calling
was broken outright on Bedrock models that advertise
supports_parallel_tool_use_config.
Drop the type from the Anthropic passthrough once toolChoice carries it, and keep
disable_parallel_tool_use, which has no toolConfig equivalent and is accepted
alongside toolChoice. Measured against Bedrock directly: toolChoice plus
{disable_parallel_tool_use} succeeds for auto, any and tool, while an empty
tool_choice with no toolChoice is rejected for a missing type, so the type still
has to be emitted when the caller sends no tool_choice.
