Step 0: 前置检查
- 版本检查（必须）：请执行 las-cli install 0.3.8。若 las-cli 命令不存在，则执行 npm i -g "@volcengine/las-cli@0.3.8"
- 新版本提醒：请执行
npm info @volcengine/las-cli version查看当前可用的最新 Skill 版本（las-cli与 Skill 版本一一对应）。若返回版本高于本 Skill 标注版本，请先提示用户升级当前 Skill。升级方式：请用户发送自然语言指令帮我安装byted-las-vlm-video技能，等待自动完成安装即可。 - 认证检查：优先使用运行时自动注入的平台身份；若当前环境未自动注入，再运行
las-cli config show确认旧版凭证las.apiKey和volcengine.region已配置。 - 资源检查:
video_url需为可访问的 HTTP(S) 地址。若输入为tos://，请先转成预签名 URL（las-cli tos presign get ...），或直接使用las-cli tos upload输出中的presigned_url。
Step 1: 初始化与准备
- 上传资源: 若输入为本地视频，先上传到 TOS。
- 准备参数: 创建
params.json。{ "video_url": "tos://my-bucket/inputs/xxx.mp4", "text": "视频里有什么？" }

las-cli price las_vlm_video \ --params-file ./params.json \ --format markdown - 用户确认: 输出预估价格后，必须等待用户确认。
Step 3: 执行任务并呈现结果（⚠️ 直接输出命令执行结果，不要精简）
las-cli operators call 命令的输出结果非常重要，不要做任何精简、修改或摘要处理。
- 执行: 必须完整返回以下命令输出的结果（markdown 格式）
las-cli operators call las_vlm_video \ --params-file ./params.json \ --format markdown \ --out ./result.md
Step 4: 失败排查
