Claude skills for refactoring: what people ask
What's the best Claude skill for refactoring?
There are 525 of them, spread over 251 repositories on GitHub. Named for it and most starred: refactor (code-yeongyu/oh-my-openagent, ★ 70k), csharp refactoring (dotnet/skills, ★ 5.8k) and deep module refactor (zebbern/claude-code-guide, ★ 4.7k). Stars rate the repository a skill sits in, not the skill.
How do I install a Claude skill for refactoring?
For refactoring, take the refactor folder from code-yeongyu/oh-my-openagent (the folder that holds SKILL.md) into ~/.claude/skills/ to use it in every Claude Code project, or into .claude/skills/ for one project. In the Claude apps, zip that folder and upload it as a custom skill in settings.
Are all these refactoring skills in English?
No: 6 of those listed, such as refactor safety and cc refactor safety, are written mainly in Chinese, Japanese, Korean or Russian rather than English, though the refactoring task is the same. Claude can follow them either way, but read them before you install.
Are these refactoring skills official?
No. None of the 525 refactoring skills comes from Anthropic's own skills repository, so all of them are community-made across 251 repositories.
Can I use these refactoring skills at work?
Of the 50 refactoring skills listed here, 43 sit in repositories under an open licence such as MIT or Apache 2.0, and preparatory refactor states no licence at all, which legally means you may not reuse it. Check the licence file before you copy one into company work.
What should I check before installing a refactoring skill?
A refactoring skill is instructions Claude follows, and it can bundle scripts Claude runs, so read SKILL.md and every script first: for refactor, that is everything in the refactor folder. 1 of the 50 here, preparatory refactor, come from repositories with under 10 stars, so few people have looked at it. Red flags: piping a download into a shell, sending files to a URL, and instructions to hide what it does from you.
