Used to turn a topic, article viewpoint, technical concept, or business process into a 16:9 horizontal teaching PPT-style infographic, and generate the image directly through image_gen .
Default Settings
- Ratio: 16:9 horizontal.
- Background: pure white or very light gray-white, clean with whitespace.
- Primary colors: tech blue, cyan-green, light cyan, dark blue-gray; a small amount of warm color is used only for key highlights.
- Art style: flat vector, rounded cards, concise icons, process arrows, PPT course page infographic.
- Text: short Chinese title + a small number of short labels; avoid long sentences and dense small text.
- Default delivery: when the user asks for an image, generation, cover, illustration, diagram, or PPT image, first organize the final prompt, then call
image_gen. When the user only wants the prompt, do not call image generation.
Use Cases
- Concept explanations for AI Agent, MCP, workflows, context engineering, RAG, product features, technical architecture, etc.
- Three-to-five-step flowcharts, before-and-after comparison diagrams, module relationship diagrams, course knowledge point summary diagrams.
- Horizontal illustrations for WeChat official account articles, course PPT illustrations, chapter concept diagrams in presentations.
- When the user explicitly mentions keywords such as "clean white background, tech blue-green, rounded cards, flat icons, process-style infographic, teaching PPT style".
Core Workflow
Step 1: Extract Content
Compress the user input into information suitable for expression in one image:
- A 4 to 12 character Chinese title.
- One core viewpoint, preferably not placed in the image, used only to guide composition.
- 3 to 5 key nodes, modules, or steps.
- Each node keeps only a 2 to 6 character short label, with 1 short sub-label if necessary.
If the user provides a long text, do not move the original text into the image; first rewrite it into process nodes, module relationships, or comparison dimensions.
Step 2: Choose Layout
Choose one structure based on the topic, keeping a single image clear:
- Horizontal process: 3 to 5 rounded cards from left to right, connected by arrows.
- Central radial: central topic card + 3 to 5 surrounding modules.
- Top-bottom layers: upper layer input/problem, middle layer mechanism/process, lower layer result/value.
- Left-right comparison: old way vs new way, problem side vs solution side.
- Closed loop cycle: cycle processes such as plan, execute, feedback, optimize.
Do not mix too many structures. The image should look like a carefully designed teaching PPT page, not a complex poster.
Step 3: Organize the Final Prompt
Write the prompt in this order:
- Clearly specify the image type and ratio: 16:9 horizontal teaching PPT-style process infographic.
- Describe the visual style: white background, tech blue-green, rounded cards, flat vector icons, thin-line arrows, subtle shadows.
- Describe the theme and structure: title, nodes, connection relationships, visual hierarchy.
- Restrict text: short Chinese labels, no long paragraphs, no dense small text.
- Add negative constraints: no black background, no cyberpunk, no photos, no 3D, no complex gradients, no clutter.

限制:不要黑色背景;不要赛博朋克;不要写实摄影;不要 3D 渲染;不要复杂大渐变;不要密集小字;不要长段落;不要装饰性元素堆叠;不要让文字互相遮挡。图片比例必须是 16:9。
Image generation rules
- When the user explicitly asks to "generate an image / directly output an image / draw a picture / include an image / 16:9 image", you must call
image_gen。 - Before calling, you may briefly provide the final prompt in the reply, but do not give a lengthy explanation of the design process.
- If the user has not given a specific topic, first infer it based on the context; if it truly cannot be inferred, then ask one brief question.
- When generating multiple images in a series, keep the same color palette, corner radius, icon style, card density, and title font-size hierarchy.
Do / Don't
Do
- Use processes, modules, arrows, and short labels to carry information.
- Keep a white background, whitespace, a blue-green tech feel, and a PPT teaching feel.
- Prioritize making a clear horizontal infographic.
- Give every card a clear purpose.
Don't
- Do not stuff the user's original text into the image in full paragraphs.
- Do not make it a realistic poster, dark tech key visual, 3D scene, or complex web UI.
- Do not pile up too many cards, icons, arrows, and explanatory text.
- Do not let blue-green gradients cover the entire image; the white background must be the primary visual.
