About this skill

Paper-Texture Childlike Hand-Drawn PPT

Convert the user's new content into a 16:9 horizontal PPT image with a light gray-white paper texture background, childlike hand-drawn illustrations, and a handwritten title feel, and by default call imagegen skill / built-in image_gen tool to generate the image.

Effect Preview

Effect Preview

assets/preview.png is a 16:9 sample image that the user confirmed as satisfactory when creating this Skill, used to demonstrate the target visual style. When generating new images later, there is no need to copy the preview image content; only reuse its corresponding visual system and layout language.

Default Settings

  • Aspect Ratio: 16:9 horizontal.
  • Background: Light gray-white paper texture or slightly wrinkled paper surface, clean, soft, and with ample white space.
  • Image Generation Method: Use imagegen skill, with the underlying call to the built-in image_gen tool.
  • Default Delivery: When the user wants images, image output, accompanying images, PPT images, chapter pages, table of contents pages, or presentation pages, organize the final prompt and call image_gen; when the user explicitly wants only the prompt, do not call image generation.

Applicable Scenarios

  • Course covers, chapter transition pages, table of contents pages, knowledge cards, and lightweight explanation pages.
  • Explain methodologies, workflows, product concepts, and AI Agent / Skills systems as friendly and easy-to-understand PPT illustrations.
  • Express a small number of short steps, chapters, viewpoints, capability modules, or comparison dimensions; the quantity is naturally determined by the content.
  • Generate horizontal WeChat public account illustrations or presentation illustrations with a children's picture book feel, handwritten feel, and light-color doodles.

Style Guidelines

  • Overall Positioning: Like a relaxed children's picture book-style course PPT, friendly, relaxed, and clear, suitable for explaining knowledge and chapter structure; do not make it a serious business template or a complex technical architecture diagram.
  • Canvas and White Space: 16:9 horizontal, with a large amount of white space, and the main subject concentrated in the middle or upper-middle of the image; a small number of small illustrations may be used as embellishments at the edges, but the image must not be crowded.
  • Background: Light gray-white paper texture, slight wrinkles, or soft paper surface texture, overall bright and clean; do not use strong gradients, strong shadows, dark backgrounds, glassmorphism, or photographic backgrounds.
  • Color System: Mainly black or dark gray handwritten text; low-saturation coral red is used for key words, numbering, or short emphasis; illustrations use soft colors such as pale blue, light yellow, gray-green, coral red, and warm gray, like light coloring with colored pencils or light watercolor.
  • Text Hierarchy: The main title uses a black handwritten style, with slightly irregular but clear and readable letterforms; key words may be highlighted with low-saturation red-orange; body text should be as short as possible, with small light gray English or short annotations used as assistance when necessary.
  • Layout Tendency: Depending on the content, choose centered title, chapter cover, table of contents list, top-bottom layering, horizontal process, left-right comparison, or lightweight module matrix. Do not fix on a single reference image layout.
  • Graphic Language: Black thin outlines, slightly irregular pencil lines, hand-drawn underlines, numbering, dashed flight trajectories, low-saturation colorful doodle illustrations, small houses, small vehicles, small tools, small plants, small books, small flags, and other lightweight elements that can be replaced according to the theme.
  • Texture: Flat hand-drawn, watercolor or colored pencil fill, slight coloring grain, loose but clean lines; no 3D, photos, heavy shadows, metallic texture, or strong tech light effects.
  • Information density: One image tells only one core theme; titles and module labels should be few and large, avoid long paragraphs and dense small text; decorative illustrations serve the content and do not overpower the main subject.
  • Variable content slots: The title, short subtitle, section numbering, table of contents items, step labels, module icons, and bottom small scenes can all be added, removed, merged, or rearranged according to user content.
  • Things to avoid: No logos, watermarks, WeChat official account text, real people, photos, 3D, glassmorphism, heavy shadows, complex gradients, complete original text, proprietary copyrighted characters, or fixed copying of the specific illustration combinations in the preview image.

Flexible layout principles

  • Intelligently choose the layout based on the paragraph structure of the user input: chapter pages, table of contents pages, processes, comparisons, layers, matrices, center radial layouts, and timelines are all fine, as long as the paper texture background, handwritten text, light-color doodles, and relaxed whitespace remain consistent.
  • The number of modules, title positions, illustration themes, numbering methods, underline paths, and emphasized words can all change with the content; do not mechanically copy the layout of the preview image.
  • Prioritize maintaining consistency in color scheme, paper texture, text hierarchy, hand-drawn lines, illustration density, and the sense of information breathing room.

Core Workflow

Step 1: Distill the content

Compress the user input into information suitable for expression in a single image:

  • One clear Chinese main title, suitable for presentation in large handwritten text.
  • An optional subtitle or conclusion in one sentence, kept within the range of a short sentence.
  • If it is table of contents or chapter content, distill it into several short titles.
  • If it is a process or methodology, distill it into a natural number of steps, nodes, or modules.
  • If it is a long text or complex viewpoint, first summarize it into the core theme, key branches, and key words; do not move large passages of the original text into the image.

Step 2: Intelligently choose the layout

Choose the most suitable structure based on the content:

  • Chapter cover: Enlarge the title in the center or upper-middle, with a small number of themed illustrations around it as accents.
  • Table of contents list: The title is at the top or on the central axis, and the table of contents items are divided into two left and right columns or a vertical short list, with hand-drawn underlines and red-orange key words for emphasis.
  • Horizontal process: Use low-saturation small illustrations, numbering, and hand-drawn arrows to express step progression.
  • Left-right comparison: The left side expresses the problem or old method, the right side expresses the new path or conclusion, and the middle is connected with hand-drawn symbols.
  • Lightweight module diagram: Place short labels and icons around the theme, and the number of modules is naturally determined by the content.

Keep a single image telling only one core relationship. The image should look like a carefully drawn relaxed course slide, not a screen full of stickers.

Step 3: Organize the imagegen prompt

Write the prompt in this order:

  1. Clearly specify the image type and ratio: a 16:9 horizontal PPT-style image.
  2. Describe the paper-texture childlike hand-drawn style: light gray-white paper texture, black handwritten text, low-saturation pale-color doodles, pencil underlines.
  3. Describe the theme and structure: title, modules, steps, table-of-contents items, or comparison relationships.
  4. Specify the illustration direction: choose lightweight doodle elements other than small houses, airplanes, vehicles, tools, books, plants, and character silhouettes according to the user's theme.
  5. Limit the text: short Chinese labels, a small amount of text, clear and readable, no dense small text.
  6. Add negative constraints: no Logo, watermark, photos, 3D, complex backgrounds, proprietary copyrighted characters, or copying the specific content of the preview image.

Step 4: Call imagegen

  • When the user explicitly asks to "generate an image / directly output an image / draw one / include an image / PPT image / chapter page / table-of-contents page", use the final prompt to call image_gen。
  • If the user only wants the prompt, output only the complete prompt and do not call image generation.

Image generation rules

  • By default, generate a single 16:9 landscape image.
  • Before calling, you may briefly provide the final prompt, but do not give a lengthy explanation of the design process.
  • If the user has not given a specific theme, first infer it based on the context; if it truly cannot be inferred, then ask one brief question.
  • When generating a series of images, keep the light gray-white paper texture background, black handwritten title, low-saturation pale-color illustrations, hand-drawn underlines, decoration density, and whitespace ratio consistent.
