+## Purpose
+
+Full sync operation: commit local changes, push to remote, sync with upstream/base branch, and detect stale branches.
+
+## Parameters
+
+| Parameter | Description |
+|-----------|-------------|
+| `--base` | Override default base branch |
+| `--no-rebase` | Use merge instead of rebase |
+
+## Workflow
+
+1. **Display header** - Show GIT-FLOW Commit Sync header
+2. **Run /commit** - Execute standard commit workflow
+3. **Push to remote** - Push committed changes
+4. **Fetch with prune** - `git fetch --all --prune`
+5. **Sync with base** - Rebase on base branch (per sync-workflow.md)
+6. **Handle conflicts** - Guide resolution if conflicts occur (per merge-workflow.md)
+7. **Push again** - `git push --force-with-lease` if rebased
+8. **Detect stale** - Report stale local branches
+9. **Report status** - Show sync summary
+
+## Output
