The github-stacks skill covers GitHub's native stacked pull requests through
the gh stack extension. Install it with
gh extension install github/gh-stack; it requires GitHub CLI 2.90.0 or later,
Git 2.20 or later, and stacked pull requests enabled for the repository. The
core workflow is gh stack init, gh stack add, gh stack submit, then
gh stack sync as the stack changes.
For automation, use non-interactive flags such as --auto and --yes because
some commands require a TTY, inspect state with gh stack view --json, and use
gh stack push instead of force-pushing stack branches manually. See the
detailed skill and
CLI reference.
