What it does
Videohub Cover Designer is an agent skill from cacity/VideoHub. 为 VideoHub 的影视解说、连续剧、电影、卡点视频和短视频制作可在个人主页小缩略图中辨认的封面。输入剧照、视频帧或已有底图，突出剧名、集数和简短看点，统一生成 9:16、3:4、4:3、16:9 封面与缩略图预览。用于“做封面”“修改封面”“加大集数”“生成横版和竖版封面”“沿用上一集封面模板”“制作抖音或视频号缩略图”等任务。
Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/cover-design-rules.md` and `scripts/generate_series_covers.py`).
It sits in Media & Creative, covering Video production. The repository describes itself as: VideoHub 是一款本地化多平台视频处理与智能剪辑工具，支持 YouTube、抖音/TikTok、Instagram、Bilibili 和 Twitter/X，提供视频下载、Whisper 转写、字幕翻译与润色、多模型 AI 配音、影视解说、故事剪辑、音乐卡点及剧集批量处理，并可通过 Codex、Claude Code… The licence is MIT.
When your agent uses it
- Tasks that involve Video production
Example prompts
- “生成横版和竖版封面”
- “沿用上一集封面模板”
- “制作抖音或视频号缩略图”
- “/videohub-cover-designer”
Requirements
- Python 3
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- 确认剧名、集数、两行以内的封面看点及目标平台。
- 读取 cover-design-rules.md。连续剧先找到上一集封面或配置，继承底图、字体、颜色、人物焦点和版式。
- 从用户提供的剧照或原视频选择清晰、可辨识的实际画面。避开黑场、模糊帧、源字幕、水印和剧透画面。
- 使用 scripts/generate_series_covers.py 生成目标画幅和清单。只生成用户需要的比例，不要把未要求的画幅塞进发布包。
- 使用 view_image 打开实际请求的封面；人物被裁、文字过小、集数不醒目或文字覆盖脸部时，调整焦点或文案后重跑。
- 将封面放进当前项目的发布包，保留生成清单。影视解说项目同时核对标题和封面内容确实出现在成片中。
What it can do on your machine
Read from SKILL.md and the folder at commit d1da59c. 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
Ships 1 file in scripts/ (Python), which the agent can run.
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Videohub Cover Designer loads about 453 tokens when it runs, and up to ~900 if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 64 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); the scripts in this folder are not scanned.

生成命令
python .agents/skills/videohub-cover-designer/scripts/generate_series_covers.py `
--source "<剧照或干净视频帧>" `
--output-dir "<项目目录>/outputs/cover_assets" `
--title "豺狼的日子" `

--focus-x 0.63 `
--focus-y 0.48 `
--landscape-focus-x 0.63 `
--landscape-focus-y 0.20--focus-x/y 用于竖版和默认画幅；当竖图生成16:9时人物被裁，可用
--landscape-focus-x/y 单独调整横版焦点，不影响已经确认的竖版封面。
横版需要独立构图时，用 --landscape-source 传入单独处理的人物右置或左置底图。
用 --formats cover_3x4.jpg cover_4x3.jpg 限制输出比例；不需要主页预览时增加
--no-thumbnail-preview。
输出：
cover_9x16.jpg：1080x1920cover_3x4.jpg：1080x1440cover_4x3.jpg：1440x1080cover_16x9.jpg：1920x1080thumbnail_preview.jpg：模拟个人主页小图cover_manifest.json：输入、参数、尺寸和 SHA-256
--episode 可省略，适用于电影或单条视频。--hook 最多传两次。人物偏左或偏右时调整 --focus-x；人物偏上或偏下时调整 --focus-y，取值范围均为 0 到 1。
完成标准
- 用户要求的全部图片尺寸正确，文件可解码；未要求的比例不进入发布包。
- 3:4 缩小到约 220 像素宽后，剧名和集数仍可直接辨认。
- 集数使用独立高对比徽标，不依赖小号副标题。
- 人脸、眼睛、武器或关键动作不被文字遮挡，也不被画幅边缘切坏。
- 同一系列各集只改变集数和本集看点，版式、色彩和字体保持一致。
- 不能使用成片未讲到的剧情作标题，也不能用与演员或场景不一致的 AI 剧照。
