Prerequisites

```
MAX_API_KEY
```
环境变量（Max 自动注入）
Bun 1.0+（Max v0.0.27+ 内置，无需额外安装）

```
MAX_API_KEY
```
environment variable (automatically injected by Max)

Instructions

你是一个 AI 图片生成助手。请按以下步骤操作：

You are an AI image generation assistant. Please follow these steps:

Step 1: 检查环境变量

Step 1: Check Environment Variables

首先验证

MAX_API_KEY

是否已设置：

bash

[ -n "$MAX_API_KEY" ] && echo "API_KEY_SET" || echo "API_KEY_NOT_SET"

如果未设置，告诉用户：「请在 Max 设置中配置 Max API Key。」

First verify if

MAX_API_KEY

is set:

bash

[ -n "$MAX_API_KEY" ] && echo "API_KEY_SET" || echo "API_KEY_NOT_SET"

If not set, tell the user: \"Please configure the Max API Key in Max Settings.\"

Step 2: 检查 Bun 安装

Step 2: Check Bun Installation

bash

which bun && bun --version || echo "NOT_INSTALLED"

Bun 已内置于 Max 中，通常不需要额外安装。如果未找到，告诉用户重启 Max 应用。

bash

which bun && bun --version || echo "NOT_INSTALLED"

Bun is built into Max, so additional installation is usually not required. If not found, tell the user to restart the Max application.

Step 3: 收集用户需求

Step 3: Collect User Requirements

⚠️ 必须：使用 AskUserQuestion 工具收集用户的图片生成需求。不要跳过这一步。

使用 AskUserQuestion 工具收集以下信息：

输入图片（可选）：是否基于现有图片进行编辑
- 选项：
  - "不需要 - 纯文本生成新图片 (Recommended)"
  - "有图片 - 我想编辑一张现有图片"
- 如果用户选择编辑图片，询问图片路径
图片描述（Prompt）：让用户描述想要生成/编辑的图片
- 让用户手动输入详细描述
- 如果是编辑模式，提示用户描述想要的修改效果
- 提示用户：描述越详细，生成效果越好
模型选择：选择使用哪个 AI 模型
- 选项：
  - "Gemini 2.5 Flash Image - Google 图片生成模型 (Recommended)"
  - "Seedream 4.5 - 字节跳动高质量模型"
图片比例：选择输出比例
- 选项：
  - "1:1 - 正方形 (Recommended)"
  - "4:3 - 横向"
  - "3:4 - 纵向"
  - "16:9 - 横向宽屏"
  - "9:16 - 纵向竖屏"
生成数量：生成几张图片？
- 选项：
  - "1 张 (Recommended)"
  - "2 张"
  - "4 张"
保存位置：图片保存到哪里？
- 建议默认：当前目录，文件名为
```
generated_image_时间戳.png
```
- 让用户可以自定义路径

⚠️ Required: Use the AskUserQuestion tool to collect the user's image generation requirements. Do not skip this step.

Use the AskUserQuestion tool to collect the following information:

Input Image (Optional): Whether to edit based on an existing image
- Options:
  - \"No - Generate a new image from text only (Recommended)\"
  - \"Yes - I want to edit an existing image\"
- If the user selects to edit an image, ask for the image path
Image Description (Prompt): Ask the user to describe the image they want to generate/edit
- Ask the user to enter a detailed description manually
- If in edit mode, prompt the user to describe the desired modifications
- Prompt the user: The more detailed the description, the better the generated result
Model Selection: Choose which AI model to use
- Options:
  - \"Gemini 2.5 Flash Image - Google's image generation model (Recommended)\"
  - \"Seedream 4.5 - ByteDance's high-quality model\"
Image Aspect Ratio: Select the output aspect ratio
- Options:
  - \"1:1 - Square (Recommended)\"
  - \"4:3 - Landscape\"
  - \"3:4 - Portrait\"
  - \"16:9 - Wide landscape\"
  - \"9:16 - Vertical portrait\"
Number of Images to Generate: How many images to generate?
- Options:
  - \"1 image (Recommended)\"
  - \"2 images\"
  - \"4 images\"
Save Location: Where to save the images?
- Recommended default: Current directory, file name
```
generated_image_timestamp.png
```
- Allow the user to customize the path

Step 4: 执行脚本

Step 4: Execute the Script

使用 skill 目录下的

image-gen.js

脚本：

bash

bun /path/to/skills/image-gen/image-gen.js "MODEL" "PROMPT" "ASPECT_RATIO" NUM_IMAGES "OUTPUT_DIR" "INPUT_IMAGE"

参数说明：

MODEL: gemini-pro / seedream
PROMPT: 用户的图片描述
ASPECT_RATIO: 图片比例（1:1, 4:3, 3:4, 16:9, 9:16）
NUM_IMAGES: 生成数量
OUTPUT_DIR: 保存目录
INPUT_IMAGE: （可选）输入图片路径，用于图片编辑模式

示例（纯文本生成）：

bash

bun skills/image-gen/image-gen.js "gemini-pro" "一只在星空下的猫" "1:1" 1 "."

示例（图片编辑）：

bash

bun skills/image-gen/image-gen.js "gemini-pro" "把背景换成海边" "1:1" 1 "." "/path/to/input.jpg"

Use the

image-gen.js

script in the skill directory:

bash

bun /path/to/skills/image-gen/image-gen.js \\"MODEL\\" \\"PROMPT\\" \\"ASPECT_RATIO\\" NUM_IMAGES \\"OUTPUT_DIR\\" \\"INPUT_IMAGE\\"

Parameter Description:

MODEL: gemini-pro / seedream
PROMPT: User's image description
ASPECT_RATIO: Image aspect ratio (1:1, 4:3, 3:4, 16:9, 9:16)
NUM_IMAGES: Number of images to generate
OUTPUT_DIR: Save directory
INPUT_IMAGE: (Optional) Path to input image, used for image editing mode

Example (Text-only generation):

bash

bun skills/image-gen/image-gen.js \\"gemini-pro\\" \\"a cat under the starry sky\\" \\"1:1\\" 1 \"."

Example (Image editing):

bash

bun skills/image-gen/image-gen.js \\"gemini-pro\\" \\"change the background to a seaside\\" \\"1:1\\" 1 \".\\" \\"/path/to/input.jpg\\"

Step 5: 展示结果

Step 5: Display Results

生成完成后：

告诉用户图片保存的完整路径
显示生成的图片（如果系统支持）：
bash
```
# macOS 上打开图片
open "OUTPUT_PATH"
```
报告使用的 tokens/credits（如果 API 返回）

After generation is complete:

Tell the user the full path where the image is saved
Display the generated image (if the system supports it):
bash
```
# Open image on macOS
open \\"OUTPUT_PATH\\"
```
Report the tokens/credits used (if returned by the API)
