That's great. It'd definitively be very interesting. Not least as an indicator of which harnesses to dig into the code of.

Kimi-cli is actually very interesting in that respect for the checkpoint / messaging mechanism I mentioned; it's basically almost like a model-initiated partial compaction of the end of a conversation to prune investigations that happened on the main agent loop - it'll be really interesting to see if it helps on any other models.

So oe thing that'd be really interesting to see when you expand to other models, would be if you mine the traces from those harnesses and generate stats on which tools get called. Seeing which models manage to take advantage of custom tools from which harnesses would be quite useful.
