AI coding ROI is earned in review. @Harvard / @_jellyfish_co : agents added 30% more code, but there was no significant gain in software output. PR review-to-merge time rose 49%. Most AI code review tools are getting it wrong, sending all their findings to humans, when in fact they should first discuss things with the coding agent and surface to HI only what the two could not agree on, along with supporting evidence. The bar for @QodoAI: less human review effort, fewer revision cycles, more software delivered. https://fion.ac/jellyfish.pdf
