Like others I found superpowers helpful maybe 4 months ago. The models don't seem to need it anymore. I also don't have the same prompting issues the author has. Opus 5.5 tends to develop the spec, assumes I agree, and builds it. I make my sandwich and come back to a spec md, a diff, other evidence of completion. I use cc cli with a cmux-like platform it can control (ie open tabs showing specs, diffs itself).

I have agents working on plans for days on their own with just a plan doc and a relatively simple prompt. I usually check the commits once in a while to see what's happening. I'm not sure how superlite would improve that.

The “assumes I agree” part is a real regression imho. Even Opus 5.5 and Fable 5.1 put out some half-baked plans most of the time.
