What issue are you seeing?
On literal first message, even with complete lack of a global AGENTS.md, in a completely empty folder, with zero context, with all skills deleted. The first message even if its Hi takes 26% of the context immediately leaving us with 74% EVEN with gpt-5.1-codex-mini medium. This literally never happened before (last i used was .91) and I havent changed any mcps or any skills or anything for MONTHS now. If its an issue on my end, what could it possible be?
