Trigger a review agent for any commit which has an open PR and has passed build. Use open weights, or at minimum a different model family from the one which wrote the code. I will be publishing a write up soon(tm), inspired by but different from, cloudflare's post.

I would napkin math the averaged cost per-review to be less than $1, which is less than our most rigorous validation pathway in CI (needs GPU for up to an hour). Time-wise around ~10-15m, with variability - and a bug in Argo with pod scheduling delays. This is fine because developers check in on their own PRs when they do and then make the changes that are needed. A key point here is that we are keeping humans in the loop in the PR.

This is a large monorepo, I would expect much lower numbers for polyrepo setups.
