PR Review

Review all changes between main and the current branch HEAD, plus any staged and unstaged working-tree changes.

Setup

1. Rebase — Unless the user says otherwise, fetch origin and rebase onto origin/main, resolving conflicts. If the branch has Alembic migrations, run alembic heads after rebase — if multiple heads exist, update down_revision to restore a single linear history.

2. Gather context — If a PR exists (gh pr view):

   • PR description, title, review comments (gh pr view --comments)
   • Linked issues (gh issue view N) to understand requirements If no PR exists, review from the diff alone.
