We need to produce a 2-3 sentence plain-text summary, objective, factual, no marketing, no superlatives, no calls to action. Must be at most 60 words. No quotes, no bullet points, no headings, no markdown. Just plain text. Summarize: skill syncs local and remote branches safely, handles fetch/pull/rebase/push workflows, conflict handling, branch alignment before merge. Problem: ensures branches are up-to-date, avoids conflicts, safe push. When to use: when user wants to sync with remote, branch behind base, pre-PR cleanup. Let's craft ~30 words.
