Imagen - AI图像生成技能

Overview

概述

This skill generates images using Google Gemini's image generation model (
gemini-3-pro-image-preview
). It enables seamless image creation during any Claude Code session - whether you're building frontend UIs, creating documentation, or need visual representations of concepts.
Cross-Platform: Works on Windows, macOS, and Linux.
本技能使用Google Gemini的图像生成模型（
gemini-3-pro-image-preview
）生成图片。它能在任何Claude Code会话中无缝创建图片——无论你是构建前端UI、创建文档，还是需要将概念视觉化呈现。
跨平台兼容：支持Windows、macOS和Linux系统。

When to Use This Skill

适用场景

Automatically activate this skill when:
  • User requests image generation (e.g., "generate an image of...", "create a picture...")
  • Frontend development requires placeholder or actual images
  • Documentation needs illustrations or diagrams
  • Visualizing concepts, architectures, or ideas
  • Creating icons, logos, or UI assets
  • Any task where an AI-generated image would be helpful
在以下场景自动激活此技能：
  • 用户请求生成图片（例如：“生成一张……的图片”、“创建一幅图画……”）
  • 前端开发需要占位图或实际图片
  • 文档需要插图或图表
  • 将概念、架构或想法可视化
  • 创建图标、标志或UI资源
  • 任何AI生成图片能起到帮助作用的任务

How It Works

工作原理

  1. Takes a text prompt describing the desired image
  2. Calls Google Gemini API with image generation configuration
  3. Saves the generated image to a specified location (defaults to current directory)
  4. Returns the file path for use in your project
  1. 接收描述所需图片的文本提示词
  2. 使用图像生成配置调用Google Gemini API
  3. 将生成的图片保存到指定位置（默认保存至当前目录）
  4. 返回文件路径，以便在项目中使用
