Sync gh-stack Stack
Use gh stack sync to fetch, rebase, push, and refresh PR state in one pass. Do not use raw git pull plus git rebase for stack synchronization.
Command contracts are based on the upstream CLI reference at https://github.github.com/gh-stack/reference/cli/.
Steps
-
Check current stack state: gh stack view --short 2>&1.
-
Run sync:
gh stack sync 2>&1
Add --prune when the user asks to clean up local branches for merged PRs:
gh stack sync --prune 2>&1
-
If sync reports a rebase conflict, it restores every branch to its original state — use the ghs:restack skill to resolve the conflicts interactively.
-
If sync reports that the local and remote stacks have diverged, it aborts without pushing anything. Report the divergence and let the user choose: adopt the remote stack, delete the stack on GitHub and recreate it with ghs:submit, or restructure locally first.
-
Report the trunk update, branches rebased or pushed, PR statuses, and any pruned branches.
gh stack sync never opens new PRs — use the ghs:submit skill for that.
