Without it, abliterated/reasoning models like huihui_ai/qwen3.5-
abliterated:9b reliably choose to write a planning response instead
of calling the tool — even with /no_think and a terse imperative
system prompt. tool_choice=required is passed through to Ollama's
chat API and removes the model's option to respond in text at all,
forcing exactly one tool call per turn.
Confirmed working with the abliterated Qwen 3.5 9B base.
