根据视频口播文案,为视频号/抖音/小红书短视频生成 3:4 竖版封面图。当用户需要给短视频做封面、配缩略图、出竖版题图时使用。触发词包括:做视频封面、生成视频封面图、视频号封面、抖音封面、小红书视频封面、竖版封面、3:4 封面、短视频题图。即使用户只是说"帮我给这个视频做个封面"或"封面还没做",只要上下文涉及短视频发布,都应该触发。通过 ai-image-generator 的 edit 模式生成(默认 MuleRun Nano Banana 2, 也可切换 APImart/Atlas/Agnes),以主持人参考图为参考图,提供 11 种可选视觉风格(默认深色科技标题风),产出符合短视频平台爆款规律的竖版封面图。不要用于公众号宽幅题图(2.35:1)、朋友圈九宫格、头像、海报等非 3:4 短视频封面场景；本 skill 只处理 3:4 竖版短视频封面。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add wwwzhouhui/skills_collection/short-video-cover@sha256:b22358bb8abef28bThe line at the top of this page pins the label git:20260726.4787fcc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
