What it does
Short Video Cover is an agent skill from wwwzhouhui/skills_collection. 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。
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 33 other files, including reference files and assets (for example `README.md`, `references/brand_baseline.md` and `references/examples.md`).
It sits in Media & Creative, covering Image generation. It works with Google Gemini. The repository describes itself as: 本项目是个人开发的 Claude Code Skills 集合，提供实用的技能工具，助力提升开发效率和内容创作。 分享一些好用的 Claude Code Skills，自用、学习两相宜，适用于 Claude Code v2.0 及以上版本。
When your agent uses it
- Tasks that involve Image generation
Example prompts
- “帮我给这个视频做个封面”
- “/short-video-cover”
Requirements
- Python 3
- A credential in MULERUN_API_KEY
- A credential in APIMART_API_KEY
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- 主标题(顶部大字) —— 4-8 字,必须是"人话"不能用行话。把文案的核心痛点用最大众的词重写。例如
- 副标题(底部大字) —— 4-6 字,给出承诺/解决方案。例如"10秒解决""一键搞定""3步搞定"
- 辅助小标题(主标题下方) —— 6-12 字,补充上下文。例如"Claude Desktop · 避坑指南""保姆级教程"
- UI 元素叙事(画面中间的视觉故事) —— 必须是"问题→解决"的双截图对比
- 表情:稳定使用"自信微笑、看镜头、像导师"——绝不用惊讶/瞪眼/夸张表情,因为 host 的人设是"踏实分享干货",不是"震惊体博主"
- 手势 —— 不必和参考图保持一致,根据风格/构图自然选择。例如:深色科技标题风用"食指轻抬指向标题",产品主视觉风用"手指向 UI",双屏对比风用"双手分指左右"。references/brand_baseline.md 里有完整手势选项。
What it can do on your machine
Read from SKILL.md and the folder at commit b98f166. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
AGNES_API_KEYMULERUN_API_KEYAPIMART_API_KEYATLASCLOUD_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Short Video Cover loads about 1.8k tokens when it runs, and up to ~150k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 472 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 472 words (~1,796 tokens).
