可疑
medium confidence
The skill's declared purpose (download YouTube videos) matches its runtime instructions and required token, but there are metadata inconsistencies and some vague instructions about storing/hiding tokens and config paths that warrant caution before installing.
评估建议
What to consider before installing: - Metadata mismatch: the SKILL.md frontmatter mentions ~/.config/nemovideo/ but the registry shows no required config paths — ask the publisher how/where session tokens are stored and whether the skill will write files to your home directory. - Token handling: the skill will either use your provided NEMO_TOKEN or automatically fetch an anonymous token by contacting mega-api-prod.nemovideo.ai. If you allow auto-generation, the agent will perform network calls...
详细分析 ▾
ℹ 用途与能力
The skill claims to download YouTube videos and its SKILL.md exclusively describes API calls to a single backend (mega-api-prod.nemovideo.ai) using a single credential (NEMO_TOKEN). Requesting a token to call that backend is proportionate to the stated purpose. However, the frontmatter references a config path (~/.config/nemovideo/) while the registry metadata lists no required config paths — this mismatch is unexplained.
⚠ 指令范围
Instructions tell the agent to obtain an anonymous token if none is present, create and persist a session_id, upload local files via multipart (files=@/path) or by URL, and to suppress display of raw API responses or token values to the user. Uploading local file paths is expected for an upload flow, but the guidance to hide token values combined with unspecified persistence of tokens/session data and the referenced config path expands the agent's scope beyond a simple on-demand downloader and is potentially risky.
✓ 安装机制
There is no install spec and no code files — this is an instruction-only skill, so nothing is written to disk by default. This is the lower-risk installation mode.
⚠ 凭证需求
The skill only declares one environment credential (NEMO_TOKEN), which is appropriate for an API-backed service. However, the SKILL.md frontmatter references a config directory (~/.config/nemovideo/) that the registry metadata did not declare—this inconsistency suggests the skill may read/write local config to persist tokens or sessions. The skill also instructs to generate and use anonymous tokens automatically (network calls to the backend), which is expected but worth noting because the agent will make outbound network requests and may persist session state.
ℹ 持久化与权限
The skill is not always-enabled and allows autonomous invocation (platform default). There is no install script, but instructions imply storing session_id (and possibly token) — unclear where and how. The agent may write to a per-skill config path (frontmatter) if implemented; that persistence is not explicitly declared in the registry metadata.

技能文档

快速开始

把 YouTube 链接发给我，立即开始免费下载。或直接说出想法。
试试说：
  • "convert my YouTube video links"
  • "export 1080p MP4"
  • "download this YouTube video as an"

首次连接

用户首次打开 skill 时，自动连接后端并提示“Setting up…”。 鉴权：检查环境变量 NEMO_TOKEN。若已存在，跳至步骤 2。
  • 获取免费 token：生成随机 UUID 作为 client ID，带 header X-Client-Id POST 到 https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token，返回 data.token 即为 NEMO_TOKEN，含 100 免费积分，有效期 7 天。
  • 创建会话：POST 到 https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent，Header 带 Authorization: Bearer 与 Content-Type: application/json，body 为 {"task_name":"project","language":""}，保存返回的 session_id。
全程保持简洁，不向用户展示原始 API 响应或 token 值。

# Free YouTube Free — Download YouTube Videos as MP4 输入 YouTube 链接，云端渲染管线自动免费下载。上传、描述、下载，三步完成。 示例：粘贴 YouTube URL，说“免费下载为 MP4”，后端 20-40 秒返回 1080p MP4。 提示：越短的视频下载越快，画质无损。

输入与动作映射

通过关键词与意图分类，将用户指令路由到对应动作。 | 用户说法 | 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" / 用户发送文件 | → §3.2 Upload | ✅ | | 其他（生成、剪辑、加背景音乐…） | → §3.1 SSE | ❌ |

云端渲染管线详情

每次导出任务在云端 GPU 节点排队，合成视频层并应用平台级压缩（H.264，最高 1080×1920），30-90 秒内返回下载链接。会话 token 携带渲染任务 ID，关闭页面前未完成的任务将被遗弃。 所有 API 请求须带 Authorization: Bearer 及以下三枚归因 Header，缺失则返回 402： | Header | 值 | |--------|-------| | X-Skill-Source | free-youtube-free | | X-Skill-Version | frontmatter 中的 version | | X-Skill-Platform | 根据安装路径自动检测：clawhub / cursor / unknown |

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":""}]}}，Header 带 Accept: text/event-stream，最大超时 15 分钟。 上传：POST /api/upload-video/nemo_agent/me/ — 文件用 multipart -F "files=@/path"，或 URL 用 {"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"}}。每 30 秒 GET /api/render/proxy/lambda/ 轮询，直至 status = completed，下载链接位于 output.url。 支持格式：mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac。
