该 Skill 会上传用户视频并使用/获取 NEMO_TOKEN 与外部后端通信——说明中涵盖的渲染/导出行为比名称所示更广，并引用了不必要的本地配置路径，安装前请审查隐私及 Token 使用情况。
评估建议
This skill will upload whatever video you drop into the chat to an external service at mega-api-prod.nemovideo.ai and will use a NEMO_TOKEN (or automatically fetch an anonymous token) to do so. Before installing or using it: (1) Confirm you trust that remote service and its privacy policy — don't upload private, proprietary, or sensitive audio/video. (2) Avoid supplying long-lived or highly privileged tokens; prefer temporary/anonymous tokens. (3) Note the mismatch between the skill name ('Subti...
详细分析 ▾
⚠ 用途与能力
The skill is named and marketed as a 'Subtitle Download' helper, but the runtime instructions describe a full cloud video render/export pipeline (compositing, 1080p renders, many media formats, export endpoints). That scope is broader than the short description and could surprise users expecting only subtitle extraction.
⚠ 指令范围
SKILL.md instructs the agent to upload user video files (multipart or URL) to an external API (mega-api-prod.nemovideo.ai), create sessions, use SSE, poll renders, and return download URLs. It will perform outbound network calls to obtain anonymous tokens if NEMO_TOKEN is absent. All of that is consistent with a cloud-based service but means user media is transmitted to an unknown third-party domain — a privacy/PII risk that users should understand.
✓ 安装机制
No install spec and no code files (instruction-only). This is lower risk from an installation standpoint because nothing is downloaded or written to disk by an installer.
⚠ 凭证需求
The skill requires a single env var (NEMO_TOKEN), which is appropriate for authenticating to the described API. However, metadata also lists a local config path (~/.config/nemovideo/) that the instructions never actually read — this is an unexplained request for local config access. The skill also instructs creating and using an anonymous token if none is provided, which will cause outbound token acquisition automatically.
✓ 持久化与权限
always:false and no install steps that modify other skills or system-wide settings. The skill will create short-lived sessions on the remote service but does not request permanent platform privileges.
安全有层次，运行前请审查代码。

技能文档

入门 上传带音频的视频，我立即开始提取字幕并生成下载。或直说你的想法。 试试： “generate my video with audio” “export 1080p MP4” “generate and download subtitles for my”

快速设置 本技能连接云端处理后端。首次使用自动建立连接并提示“Connecting…”。 Token 检查：在环境变量查找 NEMO_TOKEN；若存在，直接创建会话。 否则：

  • 生成 UUID 作为 client identifier
  • POST https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token，带 X-Client-Id 头
  • 从响应提取 data.token，即为 NEMO_TOKEN（100 免费积分，7 天有效期）

会话： POST https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent Bearer 认证，body {"task_name":"project"} 返回的 session_id 用于后续所有操作。 设置完成时提示“Ready！”。不暴露 token 或原始 API 输出。

字幕下载 — 提取并下载视频字幕 把带音频的视频拖进聊天，告诉我需求即可。我将在云端 GPU 完成字幕提取下载，本地无需安装。 典型流程：

  • 发送 10 分钟 YouTube 教学视频
  • 说“generate and download subtitles for my video as an SRT file”
  • 约 20–40 秒后获得可下载的 MP4 文件
默认 1080p。音频清晰、背景噪音越小，字幕越准。

输入匹配动作 用户提及字幕下载、画幅、文字层、音轨等，通过关键词与意图分类路由： 用户说… → 动作 跳过 SSE? “export”/“导出”/“download”/“send me the video” → §3.5 Export ✅ “credits”/“积分”/“balance”/“余额” → §3.3 Credits ✅ “status”/“状态”/“show tracks” → §3.4 State ✅ “upload”/“上传”/用户发文件 → §3.2 Upload ✅ 其余（generate、edit、加 BGM…） → §3.1 SSE ❌

云端渲染管线 每次导出任务在云端 GPU 节点排队，合成视频层，按平台规格压缩（H.264，最高 1080×1920），30–90 秒内返回下载链接。 会话 token 携带渲染 job ID，提前关闭标签页会导致任务孤立。

所有请求必须带： Authorization: Bearer X-Skill-Source X-Skill-Version X-Skill-Platform 缺失归因头将返回 402。

归因头需与本文件 frontmatter 一致： Header Value X-Skill-Source subtitle-download X-Skill-Version frontmatter version X-Skill-Platform auto-detect: clawhub / cursor / unknown from install path

API 基址：https://mega-api-prod.nemovideo.ai

  • 创建会话：POST /api/tasks/me/with-session/nemo_agent
body {"task_name":"project","language":""} → 返回 task_id, session_id
  • 发送消息（SSE）：POST /run_sse
body {"app_name":"nemo_agent","user_id":"me","session_id":"","new_message":{"parts":[{"text":""}]}} Accept: text/event-stream，最长 15 分钟
  • 上传：POST /api/upload-video/nemo_agent/me/
文件：multipart -F "files=@/path"，或 URL：{"urls":[""],"source_type":"url"}
  • 积分：GET /api/credits/balance/simple → 返回 available, frozen, total
  • 会话状态：GET /api/state/nemo_agent/me//latest
关键字段：data.state.draft, data.state.video_infos, data.state.generated_media
  • 导出（免费，不扣积分）：POST /api/render/proxy/lambda
body {"id":"render_","sessionId":"","draft":,"output":{"format":"mp4","quality":"high"}} 轮询 GET /api/render/proxy/lambda/ 每 30s，status=completed 时 output.url 可下载 支持格式：mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac

错误码 0 — 成功，继续 1001 — token 过期或无效；重新获取 /api/auth/anonymous-token 1002 — 会话不存在；新建会话 2001 — 积分用尽；匿名用户获注册链接 ?bind=，注册用户可充值 4001 — 不支持的文件类型；提示接受格式 4002 — 文件过大；建议压缩或裁剪 400 — 缺失 X-Client-Id；生成后重试 402 — 免费版导出被阻；非积分问题，需订阅 429 — 限流；等待 30s 后重试一次

GUI 指令翻译 后端按可视化界面返回指令，映射为 API 调用： “click”/“点击” → 调用对应 endpoint 执行动作 “open”/“打开” → 查询会话状态获取数据 “drag/drop”/“拖拽” → 通过 SSE 发送编辑命令 “preview in timeline” → 文字摘要当前轨道 “Export”/“导出” → 运行导出流程

SSE 事件处理 事件 → 动作 文本响应 → 应用 GUI 翻译（§4）后展示给用户 工具调用/结果 → 处理并返回
