Description
generate video files into captioned video files with this skill. Works with MP4, MOV, AVI, WebM files up to 500MB. YouTubers, content creators, educators use...
Usage Guidance
This skill is coherent for a cloud subtitle + render service, but it will upload your video/audio to an external domain (mega-api-prod.nemovideo.ai) and will create or use a token (NEMO_TOKEN) to do so. Before installing: 1) Confirm you trust the service and are comfortable with third-party processing of any videos you supply (do not upload sensitive or private videos). 2) Ask the publisher for a homepage/privacy policy and data-retention terms (none provided in the manifest). 3) Note the skill will auto-generate an anonymous token if none is present — if you prefer to control credentials, set NEMO_TOKEN yourself. 4) The frontmatter references a local config path (~/.config/nemovideo/) though the registry metadata did not — ask the author whether the skill will read or write files there. 5) Consider testing with non-sensitive sample videos first. If any of these points are unacceptable or you cannot verify the service owner, do not install or invoke the skill.
Capability Analysis
Type: OpenClaw Skill
Name: online-subtitle-generator
Version: 1.0.0
The skill is a legitimate integration for a cloud-based video subtitling service hosted at mega-api-prod.nemovideo.ai. The SKILL.md file contains standard instructions for an AI agent to manage API authentication, session handling, and video processing workflows. There is no evidence of malicious intent, data exfiltration beyond the stated purpose, or harmful prompt injection; the instructions even include a security best practice to avoid displaying raw tokens to the user.
Capability Assessment
Purpose & Capability
The skill is described as a cloud subtitle + render pipeline and its instructions target a single external API (mega-api-prod.nemovideo.ai) for session creation, SSE chat, upload, and export. Requesting a service token (NEMO_TOKEN) is coherent with this purpose. Note: the SKILL.md frontmatter declares a config path (~/.config/nemovideo/) but the registry metadata lists no required config paths — this inconsistency is likely a minor packaging/orchestration error but should be corrected.
Instruction Scope
Instructions stay within the stated purpose (auth, create session, upload videos, use SSE, poll exports). They explicitly direct the agent to POST user video files and metadata to an external service and to store a returned session_id for subsequent requests. They also instruct the agent to automatically obtain an anonymous token if NEMO_TOKEN is not set. There is no instruction to read unrelated local files, but the skill will transmit user video/audio data off-device — verify you consent to external uploads.
Install Mechanism
There is no install spec or code to be written to disk (instruction-only). This minimizes local install risk; all runtime activity is network calls described in SKILL.md.
Credentials
The only declared environment credential is NEMO_TOKEN, which matches the API authorization scheme. The skill also describes how to auto-generate an anonymous token when NEMO_TOKEN is missing; this is functionally reasonable but means the skill can obtain credentials without user-supplied secrets. The frontmatter's configPaths value (~/.config/nemovideo/) appears in the skill but the registry metadata shown earlier listed no config paths — this mismatch should be clarified. No other unrelated secrets are requested.
Persistence & Privilege
The skill does not request always: true and does not claim system-wide modifications. It asks to persist a session_id for ongoing jobs, which is reasonable for a multi-step render workflow. There is no instruction to modify other skills or agent-wide settings.
How to Use
