Description
Turn a 10-minute YouTube tutorial video into 1080p downloadable subtitle files just by typing what you need. Whether it's downloading subtitle files from vid...
Usage Guidance
This skill uploads whatever video you provide to mega-api-prod.nemovideo.ai and requires a NEMO_TOKEN (or will obtain a short-lived anonymous token). That is expected for a cloud subtitle/render service, but be aware: any video you send will leave your machine and be processed by their servers. Before using it with sensitive or private content, check the service's privacy/retention policy and prefer ephemeral anonymous tokens or short-lived credentials rather than a long-lived NEMO_TOKEN. Note the small metadata mismatch: the frontmatter mentions a config path while the registry did not — not a major issue, but worth asking the publisher for clarification if you need guarantees about local config access. If you need subtitles without sending media externally, consider a local tool instead.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-download-skill
Version: 1.0.0
The skill is a legitimate integration for the NemoVideo AI service, providing instructions for an AI agent to handle video uploads, subtitle extraction, and rendering via the `mega-api-prod.nemovideo.ai` API. It includes logic for session management, anonymous token acquisition, and error handling. While it performs minor environment checks (e.g., verifying installation paths like `~/.cursor/skills/` for platform attribution headers), it does not exhibit signs of data exfiltration, unauthorized command execution, or malicious intent.
Capability Assessment
Purpose & Capability
Name/description match the runtime instructions: the skill uploads video files and calls nemovideo.ai endpoints to extract subtitles and render exports. Requesting a service token (NEMO_TOKEN) is appropriate for this purpose.
Instruction Scope
Instructions direct the agent to upload user video files to the remote nemovideo.ai service, manage a session_id, poll for render status, and use SSE — all expected for a cloud render/subtitle workflow. Note: this necessarily transmits user media to a third party (the skill makes this explicit). The skill also reads its own frontmatter and attempts to detect an install path for attribution headers — reading its own metadata is expected, but 'detect install path' is a minor extra step that only affects header population.
Install Mechanism
Instruction-only skill with no install spec or downloaded code, so nothing is written to disk during install. Runtime network calls are used instead; that's expected for this cloud service integration.
Credentials
Only NEMO_TOKEN is required (primary credential). The SKILL.md also supports generating an anonymous token if none is present — a proportional fallback. Minor inconsistency: the registry metadata listed no required config paths, but the SKILL.md frontmatter mentions a config path (~/.config/nemovideo/); this is a small metadata mismatch but not a large credential overreach.
Persistence & Privilege
The skill does not request 'always: true' and does not ask to modify other skills or system-wide settings. It will act at runtime and can be invoked by the agent (normal behavior).
