Software Engineering Is Becoming Plan and Review — Louis Knight-Webb, Vibe Kanban

Summary

As AI coding tools eliminate traditional code-writing work, software engineering is fundamentally shifting to planning and review—but the real opportunity lies in choosing the right approach: detailed upfront planning saves 3x more time than reactive review cycles, with strategy varying dramatically by feature type and tech stack.

Key Takeaways

  1. Plan-based approach to AI coding agents requires comprehensive spec documents upfront but reduces review cycles significantly, saving roughly 3x more time than reactive review-heavy workflows with half-delivered outputs.
  2. GitHub Copilot and Claude Code haven't freed developer time—they've displaced it from coding (saving ~20 minutes per 30 minutes coded) directly into planning and review work, fundamentally reshaping the job.
  3. Frontend feature development requires different planning strategy than backend migrations; detailed specs work for backend but are 'basically impossible' for frontend due to design iteration needs requiring reactive review instead.
  4. Interrogative planning—where models ask you clarifying questions repeatedly until exhausting all edge cases—is emerging as superior to both freestyle prompting and traditional spec documents for reducing revision rounds.
  5. Engineering leadership should recognize this shift as structural, not temporary: the engineer's role evolving from 'code writer' to 'work architect and quality gate' requires different hiring, evaluation, and compensation models.

Um this I've This is So, the the title of this is is about planning and review, but I think the real point behind this is like basically what are we all going to do after AI continues to get really, really good. Uh I'm Louie. I'm the founder of a startup called Vibe Canvas, and I also started the London chapter of AI Tinkers, uh which is great community um if you're in London looking for events. And you should listen to me because I have done some stuff like get on the SweeBench verified leaderboard ahead of Open AI. This is a couple of months old now, but anyway, you know, it's always nice to know that the people talking have done some research in the space. Um the agenda for to…
