Alexey drops line-by-line code review for plan review and engineering guardrails
What happened
On October 4, a Hacker News front-page post described Alexey no longer reviewing agent code line by line. He reviews plans, sets engineering guardrails and lets merges happen automatically, and says he merged 562 PRs in two weeks. On his internal platform Sightline, a PR must pass unit tests, end-to-end tests, CI, Bugbot and Strix checks before Mergify lets it into the merge queue. A coordinator agent dispatches sub-agents to carry out the plan, with feature flags and small deployments limiting risk. For tasks running longer than a day, he follows progress through HTML reports.

Alexey changed his agent development flow to reviewing plans, setting engineering guardrails and allowing auto-merge, and says 562 PRs were merged in two weeks. On his internal platform Sightline, a PR must pass unit tests, end-to-end tests, CI, Bugbot and Strix checks before Mergify lets it into the merge queue. He uses a coordinator agent to dispatch sub-agents that execute plans, controls risk with feature flags and small deployments, and tracks long-running goals through HTML progress reports.
