Submit the current Graphite stack to the remote and open or update pull requests. User input: $ARGUMENTS.

Decide scope

• Default gt submit pushes the current branch and everything downstack from it.
• gt submit --stack (alias gt ss) pushes the entire stack rooted at trunk.
• gt submit --stack --update-only (gt ss -u) updates PRs only — won't open new ones.

If the user didn't specify scope and the stack has more than one branch, ask whether they want --stack or just the current branch + downstack.

Steps

1. Run gt ls and show the user which branches will be submitted.
2. Run git status --short to confirm there are no uncommitted changes. If there are, ask whether to gt modify -a them in first, stash, or abort.
3. Run gt sync --no-pull or gt restack if gt ls shows any branch as needs restack — do not submit a stale stack.
4. Run the appropriate gt submit command. Pass -c / --confirm to skip interactive prompts only if the user asked for non-interactive.
5. Report each created/updated PR URL from the output.

Key flags

• --stack — submit every branch in the stack (not just current + downstack)
• --update-only, -u — update existing PRs, never create new ones
• --draft — open as draft
• -c, --confirm — skip the interactive prompts
• -e, --edit — open $EDITOR for each PR description
• -f, --force — force-push (use with care; Graphite already uses --force-with-lease by default)
• --ai — Graphite drafts the PR title/body
