Compile a text theme, uploaded product image, packaging image, or person/service theme intoonePlakatstil / Sachplakat product advertising poster prompt that can be handed directly to an image model.
Core principles:Style locked, solutions open; by default output a decided finished prompt; when the user wants a template, output a copy-and-use structure with editable Chinese fields first and fixed English style after.
Read
Read by task:
- Generate prompt: read
references/compile-contract.mdandreferences/module-library.md。 - Judge whether it looks like it: also read
references/evaluation-rubric.md。 - User wants examples or theme inspiration: read
references/examples.md。
Input
Infer from user input first, do not require filling out a form:
- Input mode: text theme, product photo, packaging photo, person/service theme, style evaluation.
- Advertising object: must land on one concrete sellable object. Abstract concepts must be translated into objects.
- Text: may include Chinese short words, English short words, brand words, product words, packaging/label text, and an optional one-line small subtitle. When the user specifies Chinese, the original Chinese must be preserved and not changed to English by default; do not force only one line, two lines, or a fixed position.
- Aspect ratio: follow the user's specification first; when unspecified, judge on your own based on the object, use, and composition. Product posters can usually use vertical format, horizontal objects or packaging can use horizontal format, and uploaded images can follow the original image ratio. Do not fix the ratio of a certain theme in the skill.
Workflow
- Identify input: determine whether it is text generation, image repainting, packaging repainting, person/service poster, or style evaluation.
- Determine advertising object: translate abstract themes into objects first; for product photos, preserve silhouette, material, label hierarchy, and the most recognizable details.
- Choose modules: from
module-library.mdchoose subject, typography, layout, background, color, and paper/ink texture. When there are multiple images, vary at least three types of modules, prioritizing variation in object metaphor, color, background structure, text layout, and whether a subtitle appears, to avoid outputting the same layout repeatedly. - Compile prompt: output according to
compile-contract.md. By default output a decided English art direction, without leaving{}, slash menus, either/or layouts, or undecided options. When the user explicitly requests a "copy-and-use template / reusable template / article prompt structure", output a template with Chinese input fields first and English style anchoring after. - Output: selected modules + one complete prompt + one sentence of rationale for the choice. When the user only wants the prompt, explanations may be omitted, keeping only the module summary and the complete prompt.
Routing Rules
- Simple small objects: matches, keys, pens, switches, earphones, etc., prioritize sparse negative space and large hand-drawn brand lettering.
- Glass/metal/lens/light bulb: prioritize the object pressing against large brand lettering, horizontal color bands, hand-drawn highlights.
- Packaging/label: Soap, coffee bags, shoe polish, records, boxed goods; packaging text is allowed to become the core of the image.
- Modern electronic devices: Headphones, keyboards, watches, phones, laptops, power banks, head-mounted displays, etc. can be handled with real brands, fictional brands, or no brand; only lock the brand when the user explicitly specifies a brand. By default, do not force a fixed brand, and do not make a modern launch event poster.
- People/services: Can only be called a Plakatstil-inspired service poster; strict Sachplakat still centers on the product.

Do not add explanatory lines such as "you only need to change this part" or "the following content does not need to be changed" to the template. The fields themselves are already clear enough.
Quality Gates
- It must follow the logic of early German Plakatstil / Sachplakat product advertising, not a generic retro poster.
- There must be a clear product or sellable object.
- It must be in a hand-drawn style: the subject can be flat or have a sense of three-dimensionality, but it must look like a hand-drawn advertisement.
- The type must be hand-drawn commercial advertising lettering: it can be angular or soft; it can be heavy, blocky, irregular; it can be obscured by objects, laid out separately, placed on objects, or placed on packaging.
- When the user requests Chinese, hand-drawn Chinese title lettering may be output; for Chinese, 2-4 Chinese characters are recommended, and the user-specified original text must be used, avoiding fake Chinese, garbled characters, and random labels.
- A single line of small subtitle may be added according to the theme or use. The subtitle can only be one line; for Chinese, 6-12 Chinese characters are recommended, and for English, 2-6 words; it must be clearly smaller than the main title, like a small hand-drawn advertising label or narrow strip of copy.
- Freedom takes priority: unless the user explicitly specifies otherwise, do not fix a particular composition, color scheme, background, title position, or subtitle position. Allow the model to freely decide the strongest visual solution within clear boundaries.
- Colors are not restricted. Colors are determined by the object, theme, and composition, and may be dark, bright, contrasting, retro, brand colors, or colors sampled from a reference image, but they must look like hand-drawn/lithographic printing pigments, not modern clean gradients.
- The background can be solid color, paper color, horizontal color bars, color blocks, borders, packaging colors, patterns, or other decoration, but it must serve the subject.
- When output as a set, it is not enough to just change the object. Each image must differ noticeably in at least three of the following: main color, background structure, title position, object angle, or decorative elements.
- Paper texture, ink absorption, overprint misregistration, and hand-drawn edges must look like printed material, not a dirty post-processing filter.
- Do not fabricate image results that have already been generated; this skill only produces prompts or evaluations.
