Nano Banana Pro 电商主图

固定使用 public_model_nano_banana_pro，用“缩略图优先”方法设计主图：先解决主体轮廓、颜色对比和视觉焦点，再增加环境与品牌语气。漂亮但在手机商品卡上看不清的画面不算合格主图。

主图视觉语法

定义商品轮廓、主体占比、焦点位置、背景对比、品牌色、允许道具、留白和渠道安全区。建立 120–180 像素缩略图测试：商品是否一眼可辨、是否与背景粘连、是否误解数量、是否有多余焦点。

场景与代码

1. 小尺寸高识别主图

python3 "$SKILL_PATH/scripts/imagegen.py" generate \
  --prompt '为参考无线鼠标制作正方形移动端主图。商品以45度角占画面约82%，深蓝鼠标与浅暖灰背景形成清晰轮廓，按键、滚轮、侧键、Logo和材质准确；只保留柔和接触阴影，不生成手、电脑、文字、光效或功能图标' \
  --image /path/to/mouse.png

2. 内容电商氛围主图

python3 "$SKILL_PATH/scripts/imagegen.py" generate \
  --prompt '为参考唇釉制作竖版内容电商商品卡：珊瑚色渐变背景，商品和刷头形成对角线，少量同色膏体质感作为背景元素，顶部留标题安全区。保持管身、刷头、标签、Logo和真实颜色，不生成嘴唇、价格、功效词或其他色号' \
  --image /path/to/lip-gloss.png \
  --param aspect_ratio=4:5

3. 食品食欲型主图

python3 "$SKILL_PATH/scripts/imagegen.py" generate \
  --prompt '为参考燕麦包装制作早餐主图：包装正面清晰，旁边只有一碗按批准配方呈现的燕麦与少量蓝莓，晨光温暖、背景简洁。保持包装、Logo、文字和净含量区域，不添加牛奶飞溅、坚果、蜂蜜、人物、营养承诺或未包含配料' \
  --image /path/to/oats-package.png

4. SKU 系列货架统一

python3 "$SKILL_PATH/scripts/imagegen.py" generate \
  --prompt '为黑、白、薄荷绿三个耳机SKU分别生成主图。所有版本统一相机、45度角、商品占比、浅灰背景、阴影和Logo位置，只替换为批准颜色；每张只出现一个SKU，不生成颜色名、色号、包装或装饰道具' \
  --image /path/to/black-sku.png \
  --image /path/to/white-sku.png \
  --image /path/to/mint-sku.png \
  --batch 3

5. 跨境 Listing 视觉

python3 "$SKILL_PATH/scripts/imagegen.py" generate \
  --prompt '为参考收纳盒生成跨境Listing首图：纯白背景，盒体打开并整齐展示批准数量的分隔件，主体完整且边缘清晰。保持结构、透明度、卡扣和配件数量，不生成文字、尺寸线、国旗、徽章、家居道具、赠品或重复部件' \
  --image /path/to/storage-box.jpg

缩略图审核

在手机尺寸确认商品轮廓、颜色、Logo和核心结构仍清楚。
确认主体是唯一视觉焦点，道具不会被误认为销售内容。
核对 SKU、套装数量、包装、色差与参考资料。
检查背景对比、边缘、阴影和反射，避免悬浮或轮廓消失。
对照目标平台当前规则，另做合规版与内容电商氛围版，不混用。

执行

pip3 install requests
python3 "$SKILL_PATH/scripts/imagegen.py" init --skill-name nano-banana-pro-ecommerce-main-image
python3 "$SKILL_PATH/scripts/imagegen.py" task --task-id <taskId>

支持多图、批量、比例参数、路由和输出目录。保留主图视觉语法和批准母版，用同一套规则扩展新品与 SKU，避免店铺货架风格漂移。

YouTube

@byungkyu

YouTube Data API integration with managed OAuth. Search videos, manage playlists, access channel data, and interact with comments. Use this skill when users want to interact with YouTube. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Calls run through the `maton` CLI with OAuth login, or over raw HTTP with a Maton API key where the CLI cannot be installed. Every call is authenticated as the user's connection and reaches only what that connection's authorization allows, which the provider enforces on every request; the endpoints documented here are the ones this skill uses, and any other endpoint of this app needs the user to ask for it by name. Default to read and list calls, and confirm every write or new connection with the user. This file also documents the three constructs that turn a YouTube connection into automation, in the order they are used: the connection (the first step), a hosted function that runs a YouTube action through the Maton SDK, and a trigger that calls that function on a schedule or on an event. Those sections are the platform's own reference text, shared with the api-gateway skill, with YouTube examples; they add no YouTube capability - YouTube is not an event source, a trigger cannot read YouTube data, and the files under `references/<source>/triggers.md` are the platform's event catalogues for the sources Maton offers (time, Calendly, GitHub, Gmail, HubSpot, Linear, Notion, Slack, Stripe).
