   • feature: Support custom tool parsers #2917: Support custom tool parsers - Related to AI SDK middleware support for alternative tool parsing formats
   • MiniMax M2 <think> tags #4033: MiniMax M2 tags - Related to rendering thinking/reasoning tags in the UI

   • Have an ability to turn on / off thinking mode #2875: Have an ability to turn on / off thinking mode - Related to managing thinking/reasoning mode configuration

   The core of your request is to use extractReasoningMiddleware() from the AI SDK to properly parse reasoning/thinking XML tags. This is part of a broader feature set around AI SDK middleware support (#2917) and rendering reasoning content in the UI (#4033, #3703).

   Feel free to ignore if none of these address your specific case.
