As AI writes more code, it gets harder for people to understand what’s shipping. cubic’s review page is built to help. Every GitHub pull request gets its own page in cubic. GitHub lists a PR’s files alphabetically. In cubic, related files are grouped together, the core change comes first, and each group comes with a short explanation. The PR reads the way a teammate would explain it. For a guided walkthrough, ask AI chat to tour the PR. It goes stop by stop, opens the code at each one, and tells you what to check. When you’re done, comment, approve, and merge from the same page. Everything syncs back to GitHub, so nobody else on the team has to switch. The page works alongside cubic’s AI code review. The AI reviewer is designed to flag technical problems, like bugs and security issues. Deciding what matters is still up to people, and that’s the step this page is for. A pull request in cubic: suggested questions in AI chat, the first of four file groups with its explanation and diff, and the grouped file list

​
Open any PR in cubic

Change github.com to cubic.dev in any pull request link:
You can also open a PR from your pull request inbox. The first time, sign in with your GitHub account. If your team hasn’t connected its repositories yet, start with the developer quickstart.

​
Read the PR in order

The Changes tab splits the PR into groups of files that work together. For example, a change to an API, its caller, and its tests can be in one group. Read the groups from top to bottom, or switch to Tree to browse by folder. See Grouped changes for how cubic orders the groups and how to track what you’ve read.

​
Take a guided tour

Open AI chat in the left sidebar and ask “tour this PR”. AI chat takes you through the change one stop at a time. At each stop, it opens the code, explains what the code does, and tells you what to check. Ask a follow-up question at any stop. To ask about one part of the change, select the code and choose Add to AI chat. See AI chat for questions to try.

​
Review only what changed

When the author pushes again, click the version label at the top of the file list. Then choose Since your last review to see only the new changes, not the whole PR. If you haven’t reviewed this PR yet, choose Since previous push to see the latest update.
