Just use the 4.6 again:
Claude --model claude-opus-4-6[1m] when you start it and /model claude-opus-4-6[1m] for in session setting of the opus 4.6. What I learned is if one is creating dynamic workflow and let Claude write it, then execute it, keeps the agents spawned in rails much better than opus 4.6 during development alone.
I also press 1 ("bad") every time the survey pops up in Claude code. It is performing BAD!
