What they did
Daksh Gupta gave an AI Engineer talk called "how to build a code review agent" and published it in full on Greptile's blog, for teams that want to build their own instead of using Greptile.
Result (as claimed)
A full design write-up from a company that builds review agents for a living.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Pick a contained repo or task
Start on a branch or side project where mistakes are cheap.
Install and configure
Set up AI coding agent. Read what it can run on your machine and limit permissions where possible.
Run it on a real task
Give it a well-scoped issue and let it work. Review the diff like any pull request.
Add guardrails
Keep tests and CI in the loop, and never let an agent push to main or touch production secrets unattended.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
