Batch PR Rebase
Overview
| Field | Value |
|---|
| Date | 2026-02-08 |
| Objective | Rebase 5 open PRs against main to resolve .gitleaks.toml conflicts and fix secret-scan CI failures |
| Outcome | ✅ Success - 5/5 PRs rebased, all conflicts resolved, all mergeable |
| Context | PR #3119 merged gitleaks fix to main; 3 PRs had conflicts; all 5 had outdated workflows |
When to Use This Skill
Use this workflow when:
- ✅ Multiple open PRs need rebasing against updated main branch
- ✅ PRs have merge conflicts from the same file (e.g., config file updated on main)
- ✅ PRs have CI failures due to outdated workflow files
- ✅ You need to clean up commit history (remove redundant "retrigger CI" commits)
- ✅ Some PRs are in worktrees, others are not
Don't use when:
- ❌ Only 1-2 PRs need rebasing (use standard
git rebase workflow)
- ❌ PRs have complex multi-file conflicts requiring manual resolution
- ❌ PRs are from external contributors (coordinate with them first)
Verified Workflow
Step 1: Prepare - Fetch and Update Main
git fetch origin
git checkout main && git pull origin main
Why this works: Ensures your local main has the latest changes before rebasing PRs.
Step 2: Identify Meaningful Commits
For each PR, identify which commits contain actual work vs. CI fixes:
git log --oneline origin/main..<branch-name>
Pattern: Drop commits that:
- Are labeled "chore: retrigger CI"
- Add files that main already has (like
.gitleaks.toml)
- Only exist to fix CI on the old branch
Step 3: Rebase Using Cherry-Pick (Cleanest Method)
For PRs with conflicts, use the cherry-pick approach:
git log --oneline --all | grep "<search-term>"
git checkout main
git checkout -B <branch-name> origin/main
git cherry-pick <commit-hash>
git log --oneline origin/main..HEAD
git push --force-with-lease origin <branch-name>
Why this works:
- Creates clean history without conflict markers
- Automatically drops superseded commits
- Safer than interactive rebase for complex conflicts
Step 4: Handle Worktrees
If a PR branch exists in a worktree:
git checkout <branch-name>
cd /path/to/worktree
rm .gitleaks.toml
git rebase origin/main
git push --force-with-lease origin <branch-name>
Why this works: Git prevents checking out a branch in multiple locations; worktrees require in-place operations.
Step 5: Verify Results
After rebasing all PRs:
for pr in 3118 3117 3116 3115 3114; do
echo "=== PR #$pr ==="
gh pr view $pr --json number,title,mergeable,statusCheckRollup \
--jq '{number, title, mergeable, failing_checks: [.statusCheckRollup[] | select(.conclusion == "FAILURE") | .name]}'
echo ""
done
Success criteria:
mergeable: "MERGEABLE" for all PRs
secret-scan and security-report failures resolved
- Commit history clean (only meaningful commits)
Failed Attempts & Lessons Learned
❌ Failed: Interactive Rebase Kept Wrong Commits
What I tried:
git rebase -i origin/main
What happened: After skipping the .gitleaks.toml conflict, the "chore: retrigger CI" commit remained.
Why it failed: Interactive rebase applies commits sequentially; skipping one doesn't skip dependent commits.
What I learned: For complex conflict scenarios, cherry-pick is cleaner than interactive rebase.
❌ Failed: Git Reset Hard Blocked by Safety Net
What I tried:
git reset --hard origin/main && git cherry-pick bdbb3d71
What happened: Safety Net hook blocked the command.
Why it failed: git reset --hard destroys uncommitted changes; hook correctly prevented it.
What I learned: Use git checkout -B instead of reset for recreating branches.
❌ Failed: Rebasing in Main Repo When Worktree Exists
What I tried:
git checkout skill/architecture/dtype-native-migration
What happened: Git prevents multiple checkouts of the same branch.
Why it failed: Worktrees lock branches to prevent conflicts.
What I learned: Always check for worktrees first; work in the worktree if it exists.
⚠️ Partial Success: Removing Untracked Conflict Files
What I tried:
cd /path/to/worktree
git rebase origin/main
Solution:
rm .gitleaks.toml
git rebase origin/main
Why it worked: The file was untracked (from a previous conflict resolution), not part of the branch.
What I learned: Always check for untracked files before rebasing in worktrees.

Commands Used
git fetch origin
git checkout main && git pull origin main
git checkout main
git checkout -B <branch> origin/main
git cherry-pick <meaningful-commit-hash>
git push --force-with-lease origin <branch>
cd /path/to/worktree
rm .gitleaks.toml
git rebase origin/main
git push --force-with-lease origin <branch>
gh pr view <number> --json mergeable,statusCheckRollup
Best Practices
- Always fetch first:
git fetch origin before starting
- Identify meaningful commits: Use
git log --oneline origin/main..HEAD
- Prefer cherry-pick for conflicts: Cleaner than interactive rebase
- Check for worktrees: Use worktree if branch already checked out there
- Remove untracked files:
rm any untracked conflict files before rebasing
- Force-push safely: Use
--force-with-lease instead of --force
- Verify immediately: Check
gh pr view after each rebase
