Where humans still matter when agents write the code

The traditional GitHub-style pull request review is a waste of opportunity cost for most code changes in the agentic era. Yet simply removing it without a replacement invites complexity death spirals and unbounded product behaviour that agents cannot unwind. James McGill and Haziq Nordin join Yaniv to argue that engineers should stop reading diffs line-by-line and instead scan for architectural complexity, shift accountability to spec quality, and build new verification patchworks of end-to-end tests, fuzzing, and product review. The conversation is for any engineer or founder trying to extract real leverage from AI coding tools rather than bottlenecking them with cargo-cult process. ## Key takeaways - Line-by-line diff review is dead for most changes; the value now lies in catching complexity death spirals that agents propagate across prompts. - Data mutability, not code mutability, is the hard constraint—stateless frontend changes need far less scrutiny than anything touching persistent state. - The engineer's role is shifting from writing code to steering agents, writing specs, and verifying behaviour through tests rather than inspecting implementation. - Accountability structures must change too: if organisations remain blame-distribution systems, they will hedge to maximum review and forfeit AI leverage. - Compliance inertia (SOC 2, ISO) still mandates 'thorough review', creating first-mover risk for teams redefining what review means. - Codebase malleability is higher than ever, but unbounded complexity accumulates as context for future prompts and eventually collapses agent reliability. ## Chapters - 00:00 Introduction - 00:38 The dead and the messy - 03:28 Projector reviews to GitHub - 05:31 What code review was for - 07:09 Complexity as the last reason to read diffs - 10:21 Code malleability, data hardness - 15:51 Code review as accountability mechanism - 18:50 Product review over code review - 25:39 LLMs as spec compilers - 32:48 Verification patchwork - 36:40 Accountability and leverage - 44:11 Where to find James and Haziq ## Links and tools mentioned - GitHub: https://github.com - Enhance Labs: https://www.enhancelabs.com - Actuals: https://www.actuals.ai ## About James McGill & Haziq Nordin James McGill is a founding engineer at Actuals, building AI-native finance tools; Haziq Nordin is founder and CTO at Enhance Labs, working on product guardrails for agent-generated code.
