sync

name: "sync" description: "Merge main, commit changes, and push"

Merges from origin/main, commits any local changes with professional message generation, and pushes to remote. This ensures the current branch is always ahead of (or equal to) origin/main, never behind or diverged.

Goal: Current branch HEAD >= origin/main (no divergence, no outdated commits)

What this means:

• "Ahead" = local branch has commits that origin/main doesn't have yet
• "Equal" = local branch is at the same commit as origin/main
• "Behind/Diverged" = ❌ Never allowed - always merge first to stay current

Optional commit message hint from user input (can be empty string)

Process

Step 1: Merge from Origin/Main

1.1: Execute Merge

git fetch origin
git merge origin/main

1.2: Solve Conflicts (if any)

Git merge automatically:

• Takes all non-conflicting changes from origin/main (newer code, new files, etc.)
• Only creates conflicts where both branches modified the same lines

For conflicts, resolve by preferring current branch changes.

If conflicts occur:

• Resolve them systematically
• Stage the resolved files
• Continue with the commit process

1.3: Merge Summary

After merge completes, provide brief summary:

• What was merged: Source branch and commit range
• Files added/modified/deleted: List key changes with file counts
• Conflicts resolved: Detail any conflicts encountered and how they were resolved
• Merge result: Success status

Result: Current branch now includes all commits from origin/main. The branch is either:

• Equal to origin/main (if no local commits existed)
• Ahead of origin/main (if local commits existed before merge)

This ensures we're never behind or diverged from origin/main.

Step 2: Analyze Changes for Commit Message

Review staged/unstaged changes to understand:

• Type of change (add, fix, update, refactor)
• Scope and impact
• Key components modified Do this using git diff. Stage all unstaged changes.

Important: If changes exist, committing them (Step 6) will make the current branch ahead of origin/main. If no changes exist, skip to Step 8 - we're already synced.

Step 3: Check Plan Progress

If task.md exists, review current phase status:

• Identify which phase is being completed
• Check if this represents a major milestone
• Note any phase transitions

Step 4: Generate Professional Commit Message

Create structured commit message:

Format:

Brief description (50 chars max)

- Detailed bullet points of key changes
- Focus on WHY not just WHAT
- Reference phase completion if applicable

Step 5: Update Plan Status (if applicable)

If task.md exists and phase completed:

• Mark completed phase with ✓
• Update status documentation

Step 6: Execute Commit

git commit -m "$(cat <<'EOF'
[Generated commit message]
EOF
)"

Step 7: Push to Remote

Push changes to remote repository:

git push

If this is the first push and the branch doesn't exist on remote yet:

git push -u origin HEAD

Result: After pushing, the current branch remains ahead of (or equal to) origin/main with all changes safely on remote.

Step 8: Confirmation

Report commit hash, push status, and summary to user.

Final State: ✓ Current branch >= origin/main (ahead or equal, never behind or diverged)
