gh-stacked
gh-stacked turns the commits on your feature branch into a stack of pull requests. Each commit maps to one PR, and each PR targets the previous PR in the stack so reviewers see small, incremental diffs instead of one large branch diff.
Preview output lists commit-derived pull request actions, branches, and the base before anything is created.gh-stacked CLI · authentic preview output
