The review-first prompt is selected by default. You can switch to a direct command or download a local copy.
Read SKILL.md and any companion files shown by SkillsMP before deciding whether to install.
Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
A direct command skips the review prompt. Inspect the source before running it.
npx skills add https://github.com/ComeOnOliver/skillshub --skill unrealhub-developerThe command stays on one line. Scroll horizontally to inspect it before copying.
Prefer a local copy? Download the files currently available to SkillsMP.
Review product and feature risk before an AI coding agent starts implementation.

注意：本文件面向 Hub 代码库本身的维护与开发。 如需了解如何使用 Hub 驱动 UE 开发，请参阅
skills/use-unrealhub/SKILL.md（随 Hub 仓库一起发布）。维护规约：对 Hub 的任何功能变更（新工具、参数修改、行为变化） 都必须同步更新
skills/use-unrealhub/SKILL.md。详见下方「添加新工具检查清单」。

所有工具在 server.py 中通过 @mcp.tool() 装饰器注册。添加新工具时：
