Reasons mentat is better than every other GitHub integration I've seen:

Automatically sees and fixed CI failures

Automatically sees new discussion on PRs and Issues as it's running

Much faster than codex for some reason. Our setup scripts take 2m on our server and close to 10 on theirs

Has Internet access as it's running

Can be started from a PR. Want it to add tests to your PR? It can do that. Want it to start a followup PR? It can do that.

I thought codex would kill us but for now we're better
