I would like to see more agent harnesses adopt rules that are actually rules. Right now, most of the "rules" are really guidelines: the agent is free to ignore them and the output will still go through. I'd like to he able to set simple word filters and regenerate that can deterministically block an output completely, and kick the agent back into thinking to correct it. This wouldn't have to be terribly advanced to fix a lot of slop. Disallow "genuine," disallow "it's not x, it's y," maybe get a community blacklist going a la adblockers.
