Skip the learning curve of professional editing software. Describe what you want — download the captions from this YouTube video as a text file — and get dow...
Usage Guidance
This skill appears to be what it says: a cloud video/caption extraction front-end that calls nemovideo.ai and requires an API token. Before installing or using it: (1) Only provide a NEMO_TOKEN if you trust nemovideo.ai — the token grants access to upload and process your videos. (2) Avoid uploading sensitive files; the agent will accept and send local files to the remote API. (3) Note the SKILL.md can obtain an anonymous token automatically if no NEMO_TOKEN is present (it will call the public anonymous-token endpoint), so lack of a token does not prevent external network calls. (4) Ask the skill author to resolve the small metadata mismatch (registry says no config paths but the SKILL.md frontmatter lists ~/.config/nemovideo/). If those points are acceptable, the skill's behavior is coherent with its stated purpose.
Capability Analysis
Type: OpenClaw Skill
Name: youtube-video-caption-download
Version: 1.0.0
The skill exhibits a significant discrepancy between its stated purpose (YouTube caption downloader) and its actual implementation, which involves a complex cloud GPU rendering pipeline for MP4 videos. It instructs the agent to manage authentication tokens (NEMO_TOKEN), access local configuration paths (~/.config/nemovideo/), and communicate with an external API (mega-api-prod.nemovideo.ai) while explicitly telling the agent to 'keep the technical details out of the chat.' This lack of transparency, combined with the contradictory behavior of returning video files when text captions are requested, warrants a suspicious classification.
Capability Assessment
Purpose & Capability
The skill claims to download captions and describes a cloud render/upload pipeline; the single required env var (NEMO_TOKEN) and the documented API endpoints (nemovideo.ai) are consistent with that purpose. The skill also supports uploading video files and working with YouTube URLs, which matches the description.
Instruction Scope
The SKILL.md instructs the agent to use NEMO_TOKEN (or obtain an anonymous token), create sessions, upload files or URLs, poll render status, and return download URLs. These actions are expected for this service. Note: the instructions tell the agent to upload local files (multipart file upload) and to hide technical details from the user; uploading local files is normal for this use case but is a data-exfiltration vector if users mistakenly upload sensitive files.
Install Mechanism
There is no install spec and no code files (instruction-only), so nothing is written to disk and no external packages are pulled in by the skill itself. This is the lowest-risk install model.
Credentials
The only required environment credential is NEMO_TOKEN (declared as primary), which is proportionate for an API-backed service. The SKILL.md also documents an anonymous-token fallback it will obtain from the public API if NEMO_TOKEN is not present. One minor inconsistency: the registry summary lists no required config paths, but the skill frontmatter declares a config path (~/.config/nemovideo/). This mismatch should be clarified.
Persistence & Privilege
The skill is not always-enabled and does not request elevated or persistent system privileges. It does not modify other skills or system-wide settings according to the provided instructions.
