Human-on-the-Loop: AI Reviewing AI PRs at cortex (769 PRs/month, while raising the quality bar)

Hi, I'm Ryan, CTO at airCloset.

Disclaimer: "cortex" in this article is the internal codename for an AI platform built in-house at airCloset. It is unrelated to existing commercial services like Snowflake Cortex or Palo Alto Networks Cortex.

In Part 1 (intro) I covered the high level -- AI driving both PR reviews and incident response on top of cortex. In Part 2 (Product Graph) I went deep on cpg, the unified knowledge graph that fuses code, docs, DB schemas and infra into a single business-aware index.

This post is about the automated PR review pipeline -- AI reviews the PR, a separate AI applies the fixes, and the system merges automatically once policy gates pass. The usual critiques of AI-assisted development ("the reviewer becomes the bottleneck" and "AI code drops the quality bar") don't really apply here. The rest of this post unpacks why.
