KunanonJ Split to PRs
Turn one pile of work into a few small PRs.
Hard rules
- Do not create branches, commit, push, or open PRs until the user approves the split plan.
- Never discard user work. No destructive git commands (
reset --hard,clean -fdx, branch deletion, force-push, history rewrite) without explicit approval. - Always save a recoverable snapshot before moving work around. This often starts from dirty work on
main, so do not assume there is already a safe branch. - Stage only named files or hunks. No
git add ./git add -A.
1. Check the state
Compare the current work to the repo's default branch, including committed and uncommitted changes. Summarize the real slices you see, and use the chat history to recover intent.
Before proposing slices, find ownership signals for the touched paths (CODEOWNERS, nested ownership files, tools/ownership/PRODUCTOWNERS, or repo equivalents) and use them to identify natural reviewer boundaries.
2. Propose the split
Use judgment on detail. Usually PR titles are enough. Add a one-line scope note only when a title is unclear. Show a Mermaid diagram when there are multiple slices.
Optimize for reviewer-aligned PRs with minimal unrelated diff: split independent owners or concerns, keep tightly coupled changes together, and when stacking is necessary, order foundations before consumers.
Default to independent PRs off the default branch. Stack PRs only when the dependency is real.
Ask for approval before starting.
3. Execute the split
If there is uncommitted work, save a recoverable snapshot without changing the working tree:
SHA=$(git stash create "pre-split") if [ -n "$SHA" ]; then git update-ref "refs/backup/pre-split-$(date +%s)" "$SHA" fiFor each approved slice, create a branch from the right base, stage and commit only the planned files or hunks, then push and open the PR.
4. Report back
Keep it short: PR titles and URLs, plus anything left on the starting branch or working tree. Do not delete the backup ref or original branch unless the user asks.
