So the concrete example here is we do security scanning after on our PRs in local and after our PRs even land because they will always find some things that are real that we have overlooked. And they sort of beat humans on the … code review. And it's expensive. It … us, I think like five bucks a PR or something like that to run all the checks that we want. But that's where we made an explicit decision that it's worth it.

Who is speaking

Greg Pstrucha, Developer, Sentry. Engineer describing how his own team runs scans on its pull requests; Sentry sells AI debugging and review tooling.

Sentry sells AI or agent tools or services, so it has a reason to publish flattering numbers about AI. The passage stays in the archive; read it with that in mind.

How this was checked

Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-11-04).

Whisper transcript at about 36:59, answering the moderator's 'Greg, when does a loop pay for itself?'. The ellipses cover 'code review' ('on the code review') and 'costs'. The speaker is the Sentry developer introduced as Greg. Whisper spells the surname 'Costucia', so I could not confirm the 'Pstrucha' spelling from the transcript.

And so my advice is … instead of trying to automate everything end-to-end, build these small incremental loops throughout your system, and you will wake up one day and you will be moving two to three times faster while still being able to read the code, while still owning the architecture.
