>In the world of harness development I think that's an interesting question to answer!
The challenge isn't about harness development though, and a sufficiently complex harness can solve these tasks rather easily.
And presenting it as if you've made a novel development for solving ARC-AGI-3 leads me to believe you're willing to waste all of our time for your benefit at every step in the future.

I claim this is not so easily done, and earlier iterations of ARC-AGI did not have the constraint in the first place. You want something that generalizes across all puzzles (hopefully even the private ones), and these puzzles are extremely diverse ... and hard; telling the model the controls and some basic guidelines for the game is the only "obvious" thing you can do.
The other point of my reply was efficiency, both in terms of creating and using the harness; the discussed solution is something that anyone (in fact, likely even an LLM itself) can cook up in a few minutes; it's not much more than a game control wrapper so the agent can play around with the game in live python and some generalities as laid out in the prompt.
(But I'm always happy to be proven wrong. What harnesses did you have in mind?)
