The one thing Fable 5.1 still tops out on is the ability to take a simple "Let's engage in an interactive complexity-removing session" and materialize abstractions and semantics quickly.

You can wrap claude code in a harness without -p, it works fine. I think most of the concern was that -p resubmits the entire chat history on each prompt which is really bad for kv caching, and when Anthropic announced that they were ok with 3rd party harnesses that DO use -p I think they had figured out the routing and caching for thinking token hash ids

I believe you can use an OpenCode Go sub with any tool, was stated as such last time I looked at their docs.
