Since ~26December all Claude LLM in agent mode have had a serious regression in functionality. CONSTANTLY deviating from instructions. Horrendously bad assumptions being made. Constantly reverting to "it must be a component configuration" rather than the last 4 hours of code changes that have been worked on. I am having to repeatedly start new sessions and start over new sessions and rework work where prior to 26 December it did not operate in this manner. I don't know what LLM you are coding copilot to work with "better" but you are absolutely crippling Claude functionality with your changes. They are nearing the point of the GPT LLM's which are completely unuseable.
