    I'm not quite sold enough to invest in migrating to the Kiln ecosystem, but it looks to be a great concept and well done project.

    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.
