Build an AI code review bot in 30 minutes with Vercel Eve

Claire Vo, host of the podcast, demonstrates how to build an AI code review bot called Merge Mommy using Vercel Eve in 30 minutes, which reads pull requests, scores them across six risk dimensions, auto-approves low-risk ones, and escalates others to Slack. The bot, built in a single Codex session, is SOC 2 compatible and cleared Vo's backlog, with Intercom reporting 5x faster PR approval and reduced revert rates by using AI in the review loop.

AI writes most of my code now, and that created a new problem: a PR queue I couldn’t keep up with. In this episode, I walk through how I built Merge Mommy, a Vercel Eve agent that reads every PR after checks pass, scores it across six risk dimensions, auto-approves the low-risk ones, and pings me in Slack for anything that needs a human. I built the whole thing in one Codex session, it’s SOC 2 compatible, and it’s already cleared my backlog.

What you’ll learn:

Why AI-generated PRs create a review bottleneck and why the answer isn’t reviewing all of them

How Intercom 5x’d PR approval speed and reduced revert rates by putting AI in the review loop

Why Vercel Eve is the simplest framework I’ve found for deploying AI agents in Slack and GitHub

How I built a full PR review agent in Codex with one prompt and a few steering turns

The six components I use to score PR risk (blast radius, reversibility, data security, ops impact, verification gap, and change surface)

How I used Chrome browser use to handle Slack bot and GitHub app configuration so I never had to click through setup screens manually

Why auto-approved PRs can be SOC 2 compliant as long as the process is auditable, queryable, and in your risk policy

How to set up Slack escalation so low-risk PRs become a two-click merge with no manual review
