# 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.

## 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.

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:

  ```bash
  SHA=$(git stash create "pre-split")
  if [ -n "$SHA" ]; then
    git update-ref "refs/backup/pre-split-$(date +%s)" "$SHA"
  fi
  ```

- For 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.
