I'm a certified Superpowers hater. It's just not necessary with the modern models and fills up the context windows with garbage and adds an insane number of turns for no benefit.

I had similar prompts back when the models were terrible at instruction-following, so it was actually useful to fill up their context with a mass of instructions so they'd be less likely to forget rules.

Now I've got a few small slash commands or pasted prompts that work perfectly every time as the models follow them exactly.
