description	Review a pull request for code quality, correctness, and project conventions. Use when the user asks to review a PR, code review, or examine changes on a branch. Accepts a GitHub PR URL, PR number, or local branch name.

Code Review

Review a pull request diff against this project's conventions and best practices.

Step 1 — Obtain the diff

The user will provide one of the following:

A) GitHub PR URL

Extract the remote and PR number from the URL.

• https://github.com/openshift/lightspeed-console/pull/123 → remote upstream, PR 123

Then fetch and diff:

git fetch <remote> pull/<number>/head:pr-<number>
git diff <remote>/main...pr-<number>

B) PR number (bare number)

Assume the PR is on upstream (openshift/lightspeed-console).

git fetch upstream pull/<number>/head:pr-<number>
git diff upstream/main...pr-<number>

C) Branch name

The branch already exists locally. Determine its base branch by reading release-branches.md for the list of branches. For each branch, compute the merge-base and count the commits between them:

mb=$(git merge-base <branch> <candidate>)
git rev-list --count "$mb"..<branch>

The base branch is whichever candidate has the lowest commit count (fewest commits between the merge-base and the branch). If counts are tied, prefer main.

Then diff against the detected base:

git diff <base-branch>...<branch>
