Takeaway

As coding agents take longer per run, your job collapses to planning and reviewing — invest in specs to amortize review cost across parallel agents.

Summary

Speaker (Vibe Kanban founder, top of SWE-bench Verified) argues coding work is collapsing into planning and reviewing as writing-code share shrinks.
Two approaches: plan-heavy (spec frameworks, exhaustive question loops) which trades up-front time for less review; vs. in-the-loop YOLO which trades fewer specs for more rounds.
Matrix: front-end feature work suits in-the-loop; back-end features and migrations suit plan-heavy/test-driven approaches.
'5 minutes of planning saves 30 minutes of reviewing' — invest in plans because human time is the constraint.
Agent run-times have grown from seconds (Copilot) to 5-10 minute Claude Code sessions; when runs exceed 5 minutes engineers must change behavior toward parallel agent orchestration.

Original description

AI eats the middle, software engineers are spending all their time planning and reviewing the work of AI. If all humans are going to do is plan and review the work of AI, the biggest lever you have to ship more is to speed up planning and review.

And some examples of how teams and individuals are adapting:
- What tools are people spending their time in?
- How much time are teams spending reviewing code, how has this changed since AI?
- What are different approaches to planning work?
- Is agile and scrum dead?
