PREREQUISITE — load 
moda-core
once per session (step-0, write contract, free/metered map). Already loaded? Skip ahead. If you cannot load it, the non-negotiables: run 
moda doctor --json
before anything; 
moda brand list
before creating; every write carries the latest revision — on 
stale_revision
, re-read and retry once (it heals); send the canvas link the moment it exists; stuck or failed? 
moda ask "<question>"
— free and fast, never guess.
<!-- /moda:banner -->
<!-- moda:banner -->
前提条件——每个会话仅需加载一次
moda-core
（步骤0，编写合约，免费/计量映射）。已加载？请跳过。若无法加载，务必执行以下操作：先运行
moda doctor --json
；创建前先执行
moda brand list
；每次写入都要携带最新版本——遇到
stale_revision
时，重新读取并重试一次（即可恢复）；画布链接一生成就发送；遇到问题或失败？使用
moda ask "<问题>"
——免费且快速，切勿猜测。

Thumbnail1280×720
social
judged at ~320px wide — that is the real brief
Channel banner2560×1440
social
only 1546×423 centred is visible on every device
  • Thumbnail rules, not preferences: ≤4 words of on-image text; the subject or face fills a third of the frame; one high-contrast focal point; type ≥120px at 1280 wide so it survives the shrink. No thin weights, no full sentences.
  • Banner safe core: everything that must be seen — name, tagline, upload cadence, logo — lives inside the centred 1546×423. Decoration extends outward into the 2560×1440 field, which desktop shows and phones crop away.

说明
缩略图1280×720
social
需以约320px宽度的显示效果为准——这是核心要求
频道横幅2560×1440
social
仅中间1546×423的区域在所有设备上可见
  • 缩略图规则（非偏好）：图片上的文字≤4个单词；主体或面部占据画面的三分之一；一个高对比度焦点；在1280宽度下字体≥120px，确保缩小后仍清晰。禁止细字体，禁止完整句子。
  • 横幅安全核心区：所有必须展示的内容——名称、标语、更新频率、标志——都要放在中间1546×423的区域内。装饰元素可延伸至2560×1440的整个画布，该区域会在桌面端显示，在手机端被裁剪。

Recipe — thumbnail

制作流程——缩略图

  1. moda canvas create --name "[Episode] — thumb" --intent "[one-line brief]" --size 1280x720 --category social --brand [KIT]
    — send the link immediately.
  2. Subject first: a photo the user gave you (
    moda file upload [photo.jpg]
    ) or 
    moda media generate-image --prompt "[subject, high contrast, brand palette]" --model [MODEL]
    .
  3. Author in ONE apply: 
    moda canvas markup [CANVAS_REF] --file - --page [PAGE_ID]
    — ≤4 words, type ≥120px, one focal point (references/markup.md).
  4. The 320px check (this recipe's verify twist): 
    moda canvas screenshot [CANVAS_REF] -o thumb.png
    , then judge it at thumbnail scale — a thumbnail that only reads full-size is a failed thumbnail. Fix and re-screenshot.
  5. moda export [CANVAS_REF] --format png --pixel-ratio 2 -o [episode]-thumb.png
    .
  1. 执行
    moda canvas create --name "[剧集名称] — thumb" --intent "[一行简短说明]" --size 1280x720 --category social --brand [品牌套件]
    ——立即发送生成的链接。
  2. 先处理主体：使用用户提供的照片（执行
    moda file upload [photo.jpg]
    ）或通过
    moda media generate-image --prompt "[主体，高对比度，品牌配色]" --model [模型]
    生成图片。
  3. 一次性添加文字：执行
    moda canvas markup [画布引用ID] --file - --page [页面ID]
    ——文字≤4个单词，字体≥120px，一个焦点（参考references/markup.md）。
  4. 320px验证（本流程的关键验证步骤）：执行
    moda canvas screenshot [画布引用ID] -o thumb.png
    ，然后以缩略图尺寸查看效果——仅在全尺寸下清晰的缩略图视为失败。修改后重新截图验证。
  5. 执行
    moda export [画布引用ID] --format png --pixel-ratio 2 -o [剧集名称]-thumb.png
    导出。

Recipe — channel banner

制作流程——频道横幅

  1. moda canvas create --name "[Channel] — banner" --intent "[brief]" --size 2560x1440 --category social --brand [KIT]
    — link immediately.
  2. Author the safe core FIRST — the centred 1546×423 — then extend background, texture, and colour outward to the full frame in the same apply.
  3. moda canvas screenshot [CANVAS_REF]
    ; check that cropping to the core loses nothing that carries meaning; fix and re-screenshot.
  4. moda export [CANVAS_REF] --format png --pixel-ratio 2 -o [channel]-banner.png
    .
  1. 执行
    moda canvas create --name "[频道名称] — banner" --intent "[简短说明]" --size 2560x1440 --category social --brand [品牌套件]
    ——立即发送生成的链接。
  2. 先制作安全核心区——中间1546×423的区域——然后在同一操作中将背景、纹理和颜色延伸至整个画布。
  3. 执行
    moda canvas screenshot [画布引用ID]
    ；检查裁剪至核心区后是否丢失任何关键信息；修改后重新截图验证。
  4. 执行
    moda export [画布引用ID] --format png --pixel-ratio 2 -o [频道名称]-banner.png
    导出。

Examples

示例

  • "a thumbnail for this episode" → thumbnail recipe, judged at 320px.
  • "thumbnails for these 3 videos" → run the thumbnail recipe per video, one canvas each; the winning layout goes to moda-templates.
  • "refresh our channel art" → banner recipe, everything meaningful in the core.
  • "a YouTube banner AD" → not channel art: moda-social-ads owns paid formats.
  • "为本集制作缩略图" → 遵循缩略图制作流程，以320px尺寸为准进行验证。
  • "为这3个视频制作缩略图" → 为每个视频单独执行缩略图制作流程，每个视频对应一个画布；最终选定的布局将存入moda-templates。
  • "更新我们的频道视觉素材" → 遵循横幅制作流程，所有关键内容放在核心区内。
  • "YouTube横幅广告" → 不属于频道视觉素材：付费格式由moda-social-ads负责。

Errors

错误处理

Any typed error → load moda-core and read its recovery reference. Most likely here: type that passes full-size and dies at 320px — shrink the screenshot before delivering. 
stale_revision
heals — retry once.
任何输入错误 → 加载moda-core并查看其恢复参考文档。 最常见的问题：在全尺寸下清晰但在320px下模糊的文字——交付前先缩小截图查看。
stale_revision
问题可恢复——重试一次即可。

Make it recurring

实现自动化生成

Template-ize the winning thumbnail via moda-templates, then moda-automate the per-video instance — a thumbnail system beats a thumbnail.
See also: moda-social — other platforms, ad sets, one-off graphics · moda-core — the contract, recovery, everything Moda can do.
通过moda-templates将选定的缩略图保存为模板，然后通过moda-automate为每个视频自动生成实例——一套缩略图生成系统优于单个缩略图。
