Quick Review

This skill provides a Git workflow alternative to interactive rebase for squashing commits. The task knowledge is solid with clear step-by-step commands using git merge --squash. However, the description is vague ('git rebase 另解' - 'another explanation of git rebase') and doesn't clearly explain what the skill does or when to use it. A CLI agent would struggle to know when to invoke this based solely on the description. The novelty is limited as this is a standard Git pattern that doesn't require many tokens to explain directly. Structure is adequate but could benefit from clearer sections explaining the problem, solution, and when to use this approach versus interactive rebase.
