Any custom harness for a problem shows that harness engineering is going away. Eventually models will introspect problems, then build custom harnesses tailored to that. Then use and modify the ephemeral harness as required.
Sol Ultra style is the path forward. The models are smart enough to self serve their tooling and processes. Given a problem they can figure it out and ask for directions when needed.
Codex and Claude Code already have the workflow feature which basically does this on demand, so it's getting there.

That’s called brute force so not really.
I seriously doubt this, especially in a world in which there's not just one model.
This makes sense if the models some how become unified.
Except in this case, it isn't yet smart enough. But I agree, building this capability in is coming, and will be really awesome.
Indeed. And you can make this case about any tooling at all that is model adjacent.
