I am ignoring Fable at the moment. It’s on and off available, twice the price and does not seem to be better.

I use Opus 4.8 with OMP/Pi coding agent and Matt Pocock Skills installed. I use professional/polite/questions-based communication pattern with Opus and it seems to work fine for coding. I am always aware that I need to justify my requests so it doesn’t barf.

Of course, I would never use Claude for anything customer-facing. It’s woke to the point of being fanatical.
