Sketch Knowledge Poster Cover

Use this skill to create a finished image prompt, or call an image generation tool directly when the user asks to generate the final cover. The result must feel like an expert's hand-drawn knowledge map on warm paper: clear, collectible, educational, and highly shareable.

This is the visual style member of the sketch-knowledge family. Use it directly for covers/posters. When the same article or tutorial also needs product UI explanation visuals, route planning through the matching available with-docs sibling for this style if it exists.

Output Type

Use the explicit --out-type parameter to decide what to output. Read --out-type only as a control parameter, not as part of the user's topic.

• --out-type template: output the invocation template only.
• --out-type prompt: output the final image prompt only.
• --out-type all: output the template first, then the final image prompt.
• Omitted --out-type: default to template.

Treat 直接生成, 生成海报, 生成封面, 出图, and 生成图片 as direct image generation when an image tool is available.
