About this skill

item-detail — one-click generation of a full set of product detail images

One product image + selling point copy → detail page visuals with Chinese typography。

Difference from other skills: this skill's outputcontains text. Therefore, the first criterion for model selection isChinese glyph rendering capability—most image models render Chinese as gibberish.

Generation example

Input: product image
product-flatlay.jpg — flat-lay image of an army green cable-knit sweater, 800×800

Actual command executed (first-screen banner module):

dlazy seedream-5.0-pro \
  --prompt '电商服饰详情页首屏 banner，竖版。左侧是图1 中的军绿色麻花针织圆领毛衣的模特上身图（青年男模特，半身，落肩宽松版型），毛衣颜色、麻花织法与菱形提花必须与图1一致。右上方留白区排版中文标题，大字「粗棒麻花 复古落肩」，副标题小字「羊毛混纺 · 加厚保暖 · 男女同款」。底部一行三个圆形图标配文字「亲肤不扎」「不易变形」「机洗不缩」。整体米灰色背景，暖色调，留白克制，字体为无衬线黑体，排版整齐对齐，商业电商详情页设计感，中文字必须清晰正确无乱码。' \
  --images docs/item-detail/product-flatlay.jpg --size 3:4 \
  --save docs/item-detail/example-output.jpg

Output

example-output.jpg — 3:4 / 2K, 5 credits. Model wearing the item occupies the left side, preserving the sweater's army green color, cable knit, and diamond jacquard; the top-right title "Chunky Cable Knit, Vintage Drop Shoulder" and subtitle "Wool Blend · Thickened Warmth · Unisex" have correct glyphs and clear hierarchy; at the bottom, three line-drawing icons with "Skin-friendly, non-itchy", "Resists deformation", "Machine washable, no shrinkage", on a warm beige-gray background, with aligned typography.

1. Capability boundaries

Output module Description
First-screen banner Model wearing the item / product image + main title + subtitle
Selling point icon row 3–4 circular icons + short copy
Material description block Fabric/material close-up + descriptive text
Detail display block Partial close-up + craftsmanship description
Parameter block Size chart / specification parameters
Input Description
Product image 1 image
Product category 服饰 箱包 鞋品 婴童用品 宠物 家居用品 美妆 3C数码 电器 家具灯饰 食品厨具 珠宝饰品 工业和农业 其他
Product information Selling points within 100 characters, e.g.:商品卖点：舒适透气、柔软亲肤，适合入群：1个月-2岁宝宝

Don't do: don't fabricate features and certifications the product doesn't have; don't generate fake promotional information or fake comparison data; don't alter the product's style or color.

2. Input asset rules

Self-check these hard constraints before generation:

  • Size:20KB ~ 15MB
  • Resolution:greater than 400×400
  • Format:jpg / jpeg / png / webp

Input suggestion

Practice Description
✅ Clean product image Images with text will clash with the new layout's text; first run remove-watermark
✅ Write selling points as short phrases 亲肤不扎 is easier to lay out than 采用优质柔软亲肤面料不刺激皮肤 is easier to lay out than
✅ Control copy length Main title ≤ 8 characters, subtitle ≤ 16 characters, icon copy ≤ 5 characters
❌ Cramming ten selling points into one module It won't fit and will get squeezed into gibberish
❌ Unverified efficacy claims Compliance risk

3. Four conditions for correct Chinese typography

The biggest failure mode of Chinese detail pages isgibberish. It is stable only when all four conditions are met simultaneously:

Condition How to write
1 · Write the original text of each copy segment into the prompt Enclose in 「」:大字「粗棒麻花 复古落肩」、小字「羊毛混纺 · 加厚保暖 · 男女同款」
2 · Specify font family and font weight 字体为无衬线黑体，字号层级分明
3 · Specify layout relationships 右上方留白区排版中文标题、底部一行三个圆形图标配文字
4 · Explicitly require no garbled characters 中文字必须清晰正确无乱码

The shorter the copy, the less likely it is to break. Four-character and six-character titles have a much higher success rate than long sentences.

Generating in blocks is more stable than generating the whole page at once: one prompt for the first-screen banner, one for the selling-point block, one for the material block, and finally use a design tool to assemble them into a long image. When generating the whole page at once, the text in modules further down is more likely to break.

4. Category → Layout tone

Category Background and color tone Copy focus
Apparel Beige-gray / oatmeal, warm tone, large white space Fit, fabric, occasion
Bags / footwear Dark gray gradient, hard light, texture first Material, capacity, durability
Baby / pet Light pink / cream, soft light Safety, skin-friendliness, applicable age in months
Beauty Marble / velvet, high contrast Ingredients, texture, effect
3C / appliances Dark tech style, cool light Specifications, performance, ports
Home / furniture and lighting Real room scene, natural light Dimensions, material, matching
Food and kitchenware Wooden dining table, warm light Ingredients, craftsmanship, taste
Jewelry and accessories Dark velvet, spotlight Material, weight, craftsmanship

5. Tool invocation

This skill uses dLazy's seedream-5.0-pro(professional-grade image model, inChinese glyphs and complex typographyit is clearly stronger than similar models; the output of this skill carries a large amount of Chinese copy, and glyph accuracy is the primary metric).

Invocation method

Two equivalent ways to write it, choose one. The unified entry point automatically selects the backend, retries on failure, creates directories and writes to disk, and estimates cost:

# A. 统一入口（推荐）：可切任意后端，加 --dry-run 不计费空跑
node scripts/gen.mjs --task item-detail \
  --prompt '<见下方 Prompt 模板>' \
  --images <按下表顺序> \
  --save output/item-detail-<sku>.jpg

# B. 直接用 dLazy CLI（不想引入 Node 依赖时，效果等价）
dlazy seedream-5.0-pro --prompt '...' --images ... --save output/item-detail.jpg

Parameter conventions (fixed usage for this skill)

Parameter Value Reason
--images [商品图](up to 10 images, can add detail images and fabric images) Multiple images allow each module to use different assets
--size 3:4(first-screen banner) / 1:1(selling-point squares) / 9:16(long strip modules) Generate by module, each using a suitable aspect ratio
--resolution 2k Detail page width is usually 750~1200px, 2K is enough
--batch 2 ~ 3 Chinese typography has randomness, pick the one with correct glyphs
--save docs/item-detail/output-<sku>-<模块>.jpg Archiving by module makes it easier to assemble the long image

Cost note：seedream-5.0-pro A single image is about 5 credits, running 5 module-based generations is only 25 credits, cheaper than repeatedly rerunning the whole page.

Correction sentences appended by problem

Problem Append to the end of the prompt
Chinese garbled characters Shorten the copy; repeat each original paragraph once more; append 所有中文必须是清晰可读的简体汉字，不得出现变形、缺笔或臆造字。
Text pressed on the product 文字区与商品区不得重叠，商品占画面左侧 [X]%，文字区占右侧 [Y]%。
Layout crooked 所有文字左对齐到同一条基准线，行距均匀。
Product altered 商品区域必须与图1一致，不得重绘款式、颜色或图案。
Icons too busy 图标为单色细线描风格，线宽一致，不得加渐变或阴影。
Generating the whole page at once makes text collapse Split into module-by-module generation (Section 3)

7. Execution workflow

  1. Clean the product image（remove-watermark) to avoid old and new text clashing.
  2. Determine category → choose layout tone(Section 4 table).
  3. Compress selling points into short phrases: main headline ≤8 characters, subheadline ≤16 characters, icon copy ≤5 characters.
  4. Split modules: banner / selling-point icons / material description / details / sizing——one prompt per module。
  5. Each prompt must contain four conditions(original text + font + layout + no garbled text, see Section 3).
  6. --batch 2~3 Pick the one with correct glyphs and save it to docs/item-detail/。
  7. Proofread the Chinese character by character(this is where errors are most likely) → use a design tool to assemble it into a long detail-page image.
  8. Compliance check: whether selling points have a basis, and whether there are false promotions or absolute wording.

8. Common issues

Symptom Cause Solution
Chinese turns into garbled text Copy too long / no no-garbled-text constraint written Shorten the copy + repeat the original text + append a glyph constraint sentence
The lower the module, the more the text collapses Generating the whole page at once Split into module-by-module generation
Text pressed on the product No regions divided Append a region proportion sentence
Icon style is flashy and inconsistent Style not constrained Append a sentence for monochrome thin-line strokes and consistent line width
Product redrawn No fidelity sentence written Append a product-region fidelity sentence
Selling points embellished by the model Not restricted In the prompt, only provide the original text that should appear, and append 不得添加未提供的文案
