extract video files into captioned video files with this skill. Works with MP4, MOV, AVI, WebM files up to 500MB. content creators use it for downloading sub...
Usage Guidance
This skill appears coherent for a cloud-based subtitle extraction service, but review these points before installing or using it: 1) It will send your video files (or file URLs) to https://mega-api-prod.nemovideo.ai for processing — do not upload sensitive videos unless you trust that service. 2) It uses a single API token (NEMO_TOKEN) for authorization; only provide that token if you trust the provider. If you don't have a token the skill will request an anonymous token from the same API and use it for the session. 3) SKILL.md mentions reading its own frontmatter and detecting install-paths and a possible local config directory (~/.config/nemovideo/) — ask the skill author to confirm whether the skill reads that directory and what it contains. 4) The skill's source/homepage is unknown and owner ID is opaque; if you need higher assurance, request a published homepage, source code, or vendor documentation before sending sensitive content. If you only need to test functionality, prefer using non-sensitive sample videos and revoke or rotate any token you provide after testing.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-downloader
Version: 1.0.0
The skill is a functional integration for the NemoVideo AI service, providing instructions for an agent to upload videos and extract subtitles via a remote API (mega-api-prod.nemovideo.ai). It includes standard API handling logic, such as session management and anonymous token acquisition, and its request for filesystem access is limited to platform attribution and configuration paths consistent with its stated purpose.
Capability Assessment
Purpose & Capability
The name/description (extract video subtitles, render 1080p MP4) matches the actions described in SKILL.md (create session, upload video, request render/export). Requesting a single service token (NEMO_TOKEN) is appropriate for this API-based workflow. One minor inconsistency: the SKILL.md frontmatter lists a config path (~/.config/nemovideo/) while the registry metadata said no required config paths.
Instruction Scope
Instructions are focused on establishing an API session, uploading video (multipart or URL), polling render status, and returning a download URL. They instruct reading the skill's own frontmatter and detecting an install path (~/.clawhub/, ~/.cursor/skills/) to set an attribution header — this requires checking standard user paths but does not instruct accessing unrelated files. The flow also includes obtaining an anonymous token if NEMO_TOKEN is absent (network POST).
Install Mechanism
Instruction-only skill with no install spec and no code files — lowest-risk install surface (nothing written to disk by an installer).
Credentials
Only NEMO_TOKEN is declared as required (primary credential), which is proportionate for a cloud API. The SKILL.md also references a config path in its metadata (possible local config read) and will use an anonymous-token fallback if no token is set. There are no unrelated credentials requested.
Persistence & Privilege
always:false and normal autonomous invocation are used. The skill does not request permanent presence, nor does it instruct modifying other skills or system-wide settings.
