Good, Cheap, Fast PR Reviews with O3 and Cursor

I’ve recently started using this prompt in cursor:

Please review <PR_LINK> . Use the GitHub CLI. Don't nitpick, but do identify major issues and inconsistencies.

I use the o3 model in cursor’s max mode with this prompt. I have the github CLI setup locally, and the model knows how to use the CLI to get the code it needs to review:

brew install gh        # one-time
gh auth login          # follow the prompt

O3 delivers some of the best PR reviews I’ve seen: far superior to other AI tools and better than all but the top human reviewers (everyone’s too busy writing their own PRs). It automatically applies your project’s cursor rules to ensure PRs follow your style guidelines.

These reviews are really good, especially for self-reviewing your own code. You should try it out.
