Oh, this actually re-writes tools? I assumed another prompt optimizer but looks like this is an actual harness tuner.

yeah exactly. The tool re-writes have been the biggest gains. A ton of agent issues are in the tool layer, so letting the loop optimize the tools makes instances of the agent much faster and more accurate.
