1"harness engineering, which is a thing that is kind of near and dear to my heart kind of having invented the term here"Origin / framingIntro
2"I had an insane idea that I would try and get this tool to do my job."Origin storyOrigin story
3"if you're not in the habit of kind of completely retooling your stack in the way you work with every point release of the model, you are in a way missing out on what it is that you can achieve with these tools"Pace of disruptionPace of disruption
4"Human time is the fundamentally scarce resource that we have."Foundational constraintsNew constraints
5"we have to find ways to make all these nonfunctional requirements of writing good software legible to the agent"Write it downWriting down
6"I never want to give the same review feedback twice."Write-it-down ratchetReact/suspense analogy
7"Harness engineering is making context around what it means to do a good job legible. And then just in time surface to the agent over the course of its trajectories in order to steer and refine its output to make sure that every PR we get adheres to the golden thread of what we consider to be acceptable, high quality aligned software."DefinitionDefining harness engineering
8"I try and put my interventions as far right in the process as I can. In order to minimize my own synchronous time having to engage with these issues."Shift rightShift right, not left
9"it's up to us to prune latent space, to tell it which choices we want to make"Pruning latent spacePruning latent space
