[Bug] Sonnet Debugging: Inefficient Circular Reasoning and Limited Context Resolution

Bug Description
It seems that Opus to Sonnet is coming quicker. It also seems counter productive in that Sonnet when debugging creates circular plans and cannot find all occurences of problem code and its context is limited so it repeats old plans. Opus debug seems better, but cutting it off, makes me used 10x more prompts with Sonnet and still does not solve problem. There is always snippets of bad code left which causes circular debug plans.
