I tried out Codex over the past few days. It's good, and the one feature that I really liked was the ability to review the diff inside the app and leave inline comments. No more referring to code by file name and line number, or saying "change this variable inside this function."

But I like using Amp Code more. So I built review-for-agent: a local web UI that shows your uncommitted changes as a diff, lets you leave inline comments, and exports a structured Markdown file you can paste straight back into your agent's chat.

It's a single Go binary that runs locally and works with any agent.
