gpt-image-2-api-skill

Use this skill whenever the user asks how to call or run GPT-Image-2 image generation or editing APIs, mentions gpt-image-2, /v1/images/generations, /v1/images/edits, response_format, b64_json, url image output, multipart image edits, or asks for curl/script examples for image generation. Prefer this skill even if the user only says "生图怎么调", "测试生图", "图片接口", "生成图片", "画图", "改图", "修图", "图片合成", "生成海报", "生成头像", or "OpenAI 图片接口".
