image-design

image-design is a skill for Claude Code, Codex from renky1025/agent-skills. It costs 102 tokens per session (2,547 once invoked), scanned A, original, MIT.

A guide for creating detailed prompts for AI-generated images using photographic choices such as the subject, composition, lighting, camera view, style, and texture.

In plain words
What is it for?
It helps describe subject placement, leading lines, balance, perspective, light direction, color contrast, and other visual details for tools such as ImageGen, Midjourney, or Stable Diffusion.
Why use it?
It gives image requests enough visual direction to produce a specific composition instead of leaving the result open to guesswork.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

image-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

高级质感图片设计

帮助用户生成专业级的 AI 图片提示词,遵循摄影学五大核心维度。

核心公式

[主体描述] + [构图位置] + [光线逻辑] + [相机视角] + [风格与质感]

每一张高质量 AI 图片的提示词都应覆盖这五个维度。


一、主体描述 + 构图位置

位置提示词

场景需求 提示词
主体偏左 positioned at left one-third of the frame
主体偏右 subject at right one-third of the frame
主体偏上 subject placed at top one-third of the frame
主体偏下 subject positioned near bottom third

平衡元素写法

用法 提示词 效果
光平衡 balanced composition through contrast between light and shadow 明暗平衡
物体平衡 counterbalanced by small object on the opposite side 物体对重
色彩平衡 asymmetrical balance through warm and cool tones 色彩平衡
结构平衡 balanced by architectural elements in background 结构支撑画面

动线写法

类型 提示词 效果
道路动线 leading lines from foreground toward the subject 从前景引导视线进入画面
光线动线 diagonal light from top-right guiding viewer's eye 用光的方向引导视线
透视动线 path leading into depth, vanishing perspective 增强空间深度
目光动线 subject looking toward distant light 人物目光带出画外空间

构图模板

[主体], positioned at [left/right/top/bottom] one-third of the frame,
[leading lines / light direction] guiding toward the subject,
[balance element description],
[lighting style],
[environment],
--ar [aspect_ratio]

二、光线逻辑

三角公式:光线 = 方向 × 光比 × 色温

1. 方向:光从哪来、打在哪、造成什么结果

三要素:方向(from right)、照射对象(subject's face)、阴影结果(long shadows)

正确写法示例:

soft sunlight entering from the right window, lighting the subject's face, casting long shadows on the table

主光与辅光
(subject), lit by warm key light from the right, soft fill light from the left, creating balanced shadows

2. 光比:控制画面的深度与视觉节奏

AI 模型倾向于"亮度平均",必须明确告诉 AI:哪里是亮面、哪里是暗面、亮暗之间是突变还是渐变。

示例:

a man standing under a streetlight, face illuminated brightly, background fading into shadow, strong contrast ratio, smooth light falloff

3. 色温:光的情绪与时间逻辑

错误:warm lighting(整张图偏橙,像套滤镜)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
