Split and Ship

Ship an approved split plan as separate branches, commits, and PRs.

Context

A split plan must exist in the conversation. The plan specifies an ordered list of groups, each with a name, file list, and branch topology (stacked or independent).

Step 1: Prepare Working Tree

1. Detect the default branch: gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name'
2. Check the current branch and whether a PR already exists for it using gh pr view
3. Save all staged changes, then unstage everything (git reset)
4. Stash all changes including untracked files (git stash --include-untracked) so files can be selectively restored per group

Verify git stash list shows the saved changes before proceeding.

Step 2: Ship Each Group
