Claude Code's handling of a thinking setting of `disabled` changed. Under a certain condition, and when the setting is not marked as mechanical, it now becomes `adaptive` instead. In some cases the display is set to summarised, and an explicitly chosen display is kept.\n\n**Why**\n\nIn some situations the model may think even though thinking was set to off.\n\n- Area: Thinking\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: yes"}
