Pull-requests

In 2026, elite engineers are not measured by lines of code or hours worked. They deliver value through speed, quality, and AI leverage — shipping small changes, removing waiting, and focusing on outcomes over activity. This post explores the new formula for engineering excellence and the habits that separate average teams from elite ones.

Today's pull request is built around a diff. You review what changed, not how it came to be. With coding agents, that model is starting to leak: a clean diff can hide a messy session, skipped constraints, or a plan that was wrong for three iterations before it was right. This post explores a new kind of PR — one where the artifact under review is the agent session itself: the prompts, the tool calls, the rejected paths, the plan, and the human's choices along the way. It compares the idea to existing practices like AI review bots, stacked diffs, build provenance, and "session provenance", and argues that making the session the primary review surface is genuinely new — and probably inevitable.
