Real office whiteboard hand-drawn explainer diagram

Effect preview

Turn the topic, viewpoint, article, process, or system structure given by the user into a whiteboard hand-drawn explainer diagram that looks like it was photographed in an office meeting room. The focus is "real whiteboard photographic feel + on-site Marker hand-drawing + clear explanation," rather than a clean vector poster, PPT template, or commercial illustration.

Top-level conventions

Default aspect ratio：16:9
Default language: primarily Chinese, with a small amount of mixed Chinese and English allowed
Default art style: real office whiteboard photographic feel + thick Marker hand-drawn explanation
Default output: a complete Chinese prompt that can be used directly for image models
Image generation tool: when the user requests "draw one / generate an image / directly output an image / draw it for me / start drawing," organize the final prompt and then call imagegen / image_gen
Tool boundaries: this skill is only responsible for the real office whiteboard style; when generating images, do not call other illustration-type skills to rewrite the style

Applicable scenarios

Prioritize for:

Whiteboard hand-drawn explainer diagrams, office whiteboard diagrams, meeting room whiteboard diagrams
Startup retrospectives, project retrospectives, technical solution explanations, Agent / system / process breakdowns
Problem → Analysis → Solution、Before → Process → Result, pain point → diagnosis → solution
Need simple sketch symbols such as people, robots / Agents, computers, documents, clocks, gears, magnifying glasses, warnings, check marks, and charts to help tell the story
The user provides long text and wants it compressed into a whiteboard explainer image with 2 to 3 modules

Not suitable for:

Clean white-background architecture diagrams, pure infographics, courseware-style whiteboard diagrams
E-commerce posters, official account covers, PPT templates, tech blue light, cyber style, 3D rendering

Reference Files

references/visual-style.md: fixed visual specifications and prompt skeleton. Read when writing the final prompt or when the art style needs to remain consistent.

Core Workflow

Step 1: Distill the whiteboard explanation logic

Distill from the user's content:

Title: 4 to 12 characters, like a large title on an on-site whiteboard
Core judgment: the one sentence this image should make people remember
Structure: prioritize Problem → Analysis → Solution or Before → Process → Result
Key numbers / keywords: 1 to 3, which can be enlarged, circled in red, or underlined
Visual symbols: people, Agents, documents, computers, clocks, gears, magnifying glasses, warnings, check marks, bar charts, growth arrows, etc.

If the user provides a long text, do not copy the main body; retain at most the title, module names, keywords, short sentences, and key numbers.

Step 2: Organize into an on-site whiteboard layout

Default composition:

Top: a very large handwritten Chinese title
Below the title: a line of subtitle or logic chain connected with arrows
Middle: 2 to 3 modules telling the story, with thick arrows connecting the modules
Bottom: a striking summary sentence or Quote, with keywords emphasized by red circles, blue underlines, or green check marks

Common module names:

问题 Problem
分析 Analysis
解决 Solution
之前 Before
过程 Process
结果 Result
记忆 Memory
自动化 Cron
Agent

Step 3: Read the fixed visual specification

Before preparing to output the final prompt or calling imagegen, read references/visual-style.md, and merge into the final prompt its photographic whiteboard feel, Marker strokes, color scheme, layout, text rules, and things to avoid.

Step 4: Deliver the prompt or generate the image directly

User only wants the prompt: output the final prompt.
User explicitly wants an image: after organizing the final prompt, call imagegen / image_gen。
User asks for multiple directions: give at most 3 different whiteboard story structures, and keep every direction in a realistic office whiteboard style.

Prompt Writing Rules

The final prompt must include:

"Generate a 16:9 horizontal realistic office whiteboard hand-drawn explainer image"
Whiteboard photographic feel: frame, slight reflections, eraser marks, dust, residual pen marks, pen tray, eraser, whiteboard markers, slightly blurred office meeting room background
Hand-drawn feel: thick black Marker, slightly shaky lines, imperfect, diagonal scribble fill, simple stick-figure icons and people
Color scheme: black for the main body, blue for the main flow, red for key points / errors / warnings, green for solutions / success / check marks, a small amount of yellow for light bulbs or inspiration
Text: mainly Chinese, short and clear, like whiteboard handwriting, mixed Chinese and English allowed
Prohibited: no PPT template style, flat vector style, tech blue glow, cyber style, clean UI, card-based design, gradient backgrounds, refined illustrations, 3D rendering, overly smooth icons

Generate the image directly

When the user explicitly asks to generate an image, use the organized complete prompt to call imagegen / image_gen. After generation, only give a brief response, do not output lengthy analysis.

Do / Don't

Make the image look like a real meeting room whiteboard photo
First distill the story structure, then arrange the modules
Explain clearly with thick Marker, circles, underlines, arrows, and simple symbols
Control the amount of text so keywords are readable
Keep eraser marks, residual pen marks, reflections, and whiteboard objects

Don't

Do not make it a pure white background vector infographic
Do not copy the user's original text onto the whiteboard in full paragraphs
Do not use large-area gradients, tech blue glow, glass texture, or 3D
Do not make it a card-based UI or PPT template
Do not make the whiteboard too clean, too much like a commercial illustration, or too smooth
