图片换背景（image-background-replace）

Overview

对已有图片做整体背景替换/换场景，保留前景主体不变。覆盖商品换场景、人像换背景、宠物换场景、电商白底图、证件照换底色（白/蓝/红）、文字描述任意目标场景的 AI 生成。本工具不能输出透明背景。

API Mapping

• 背景替换：image_gummy_generate_v45

Dependencies

• meitu-cli: >=2.0.6（npm install -g meitu-cli@latest）
• 凭证：CONFIG AKSK → meitu tools update；EXEC AKSK → 实际执行（见根 CONFIG.md）
• 环境变量：MEITU_OPENAPI_TOOL_TASK_MODE=command

路径别名：$VISUAL = {OPENCLAW_HOME}/workspace/visual/

Core Workflow

Preflight → Execute → Deliver

Preflight

1. meitu --version ≥ 2.0.6（否则 npm install -g meitu-cli@latest）
2. 确认已跑过 meitu tools update（用 CONFIG AKSK）
3. 当前 AKSK = EXEC，且 MEITU_OPENAPI_TOOL_TASK_MODE=command
4. 解析 output_dir：openclaw.yaml → ./output/ ｜else → $VISUAL/output/image-background-replace/；mkdir -p

Execute

触发信号 / 路由规则

场景	判定关键词	路由
整体背景替换	换背景、换场景、换底色、证件照换底	image_gummy_generate_v45

决策顺序： 0. 前置拦截：prompt 含"透明"/"透明底"/"透明背景" → 不调用本工具，提示走抠图

1. 参数齐全判断：image_url 缺失 → 追问；prompt 缺失 → 用默认"白色背景"
2. 唯一路由：调用 image_gummy_generate_v45

单 API 工具：参数齐全即调用，失败重试 1 次后返回错误；不做跨工具兜底。

参数定义
