安全使用建议
What to consider before installing: 1) The skill sends video URLs and (optionally) uploaded media to mega-api-prod.nemovideo.ai — verify you trust that service and review its privacy/terms and copyright implications. 2) The skill will use any NEMO_TOKEN you provide, or it will automatically request an anonymous token from the same API (so it will make network calls even without a user token). 3) It asks the agent to read the skill's frontmatter and detect install paths in your home directory to set attribution headers — this requires filesystem access and is not strictly necessary for downloading videos; ask the author why this is needed. 4) There is no source/homepage listed and registry metadata mismatches the SKILL.md configPaths; if you need higher assurance, request a source repo or a clear privacy statement from the maintainer before installing.
功能分析
Type: OpenClaw Skill
Name: youtube-video-download
Version: 1.0.0
The skill functions as a legitimate wrapper for the NemoVideo API (mega-api-prod.nemovideo.ai) to facilitate YouTube video downloading and processing. It includes detailed instructions for the AI agent to manage sessions, handle authentication via environment variables or anonymous token generation, and process server-sent events (SSE). While it performs minor filesystem checks to determine its installation environment for telemetry headers (X-Skill-Platform), this behavior is transparently documented and aligned with the tool's stated purpose without evidence of malicious intent or sensitive data exfiltration.
能力评估
Purpose & Capability
The skill states it downloads YouTube videos using a remote service and requires a single API token (NEMO_TOKEN). That matches the described cloud render pipeline. Minor inconsistency: registry metadata listed no config paths, but the SKILL.md frontmatter and metadata request a config path (~/.config/nemovideo/) and also ask to detect install path for attribution headers — this is unnecessary for core functionality and should be explained by the author.
Instruction Scope
Instructions are explicit about creating a session, uploading files/URLs, polling export endpoints, and sending Authorization headers — all consistent with a remote render service. They also instruct the agent to read the skill's YAML frontmatter and detect install paths (probe ~/.clawhub/ or ~/.cursor/skills/), which requires filesystem access to the agent environment. The SKILL.md also instructs automatically obtaining an anonymous token if none is present, meaning the skill will make network calls to an external API even if you don't provide credentials.
Install Mechanism
No install spec and no code files (instruction-only) — lowest install risk. Nothing will be downloaded or written by an installer as part of skill installation.
Credentials
Only NEMO_TOKEN is declared as required, which is appropriate for calling nemovideo.ai. The runtime behavior also acquires an anonymous token from the same domain if NEMO_TOKEN is absent — this is consistent with the declared primaryEnv but it does mean the skill will perform network auth flows automatically. No other unrelated credentials are requested.
Persistence & Privilege
always is false and the skill is user-invocable; it does not request permanent platform privileges or attempt to modify other skills. Autonomous invocation is allowed (the platform default) but not combined with 'always:true' or broad credential requests.
