Usage Guidance
This skill uploads your video files to an external service (mega-api-prod.nemovideo.ai) and uses a NEMO_TOKEN (or it can obtain a short-lived anonymous token) to operate. Before installing or using it: 1) Confirm you're comfortable uploading the specific videos (they will leave your machine). 2) Verify the NEMO_TOKEN you provide is the intended service token and not a different secret. 3) Be aware the skill may probe install paths (~/.clawhub, ~/.cursor/skills/) to populate an attribution header — this is a minor privacy action. 4) If you need to keep content private, do not upload it to third-party services. 5) If you want stronger guarantees, ask the skill author for a privacy/data-retention policy or a trustworthy homepage before using it.
Capability Analysis
Type: OpenClaw Skill
Name: video-subtitle
Version: 1.0.0
The skill bundle provides a legitimate integration for the NemoVideo AI service, allowing users to generate and embed video subtitles via a cloud rendering pipeline. It contains detailed instructions for the agent to manage authentication (including an anonymous trial token workflow), session state, and file uploads to 'mega-api-prod.nemovideo.ai'. While it includes logic for environment discovery (checking install paths like ~/.cursor/skills/ for attribution headers) and handles remote tool calls via SSE, these behaviors are aligned with the stated purpose of a cloud-integrated video editing tool and do not exhibit malicious intent.
Capability Assessment
Purpose & Capability
The skill is a video subtitle/encoding helper and only requests a single service credential (NEMO_TOKEN) and describes API calls for uploading videos, creating sessions, checking credits, and exporting rendered MP4s — all directly aligned with the described purpose.
Instruction Scope
Instructions explicitly direct the agent to upload user-provided video files (necessary for the feature), to call the external nemovideo.ai API, and to generate an anonymous token if no NEMO_TOKEN is present. The skill also instructs detecting the install path (~/.clawhub, ~/.cursor/skills/) to set an X-Skill-Platform header — this is a minor scope creep because it requires probing install paths (privacy-sensitive but not obviously malicious).
Install Mechanism
There is no install spec and no code files (instruction-only), so nothing is written to disk or downloaded during install — lowest-risk installation behavior.
Credentials
Only one environment variable is declared (NEMO_TOKEN) and it is the expected credential for the remote API. The SKILL.md does not request other unrelated secrets or system credentials.
Persistence & Privilege
The skill is not always-enabled and does not request elevated agent privileges. It can be invoked autonomously (platform default), which is expected for skills; no evidence it modifies other skills or system-wide configs.
