Usage Guidance
This skill appears to implement a cloud subtitle+render pipeline and needs a NEMO_TOKEN (or will mint an anonymous token) and will upload your videos to mega-api-prod.nemovideo.ai for processing. Before installing or using it: 1) Verify the provider — there is no homepage or source URL in the registry, so confirm who operates nemovideo.ai and review their privacy policy; 2) Do not upload sensitive or private videos until you trust the service (uploads are sent to a third-party cloud); 3) Be aware the skill may automatically request an anonymous token and use it as NEMO_TOKEN — if you prefer control, set your own token instead of letting the agent mint one; 4) Note the name 'Chrome Extension' is misleading — this is an instruction-only cloud integration, not a browser extension, and there is a minor metadata inconsistency about config paths; 5) If you need higher assurance, ask the publisher for a homepage, source code, or a privacy/data-retention statement before proceeding.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-generator-chrome-extension
Version: 1.0.0
The skill is a legitimate integration for a cloud-based video processing service (nemovideo.ai). It provides instructions for the agent to manage authentication via anonymous tokens, upload video files, and poll for rendering status. All identified behaviors, including the automated token acquisition and file transfers to 'mega-api-prod.nemovideo.ai', are consistent with the stated purpose of generating subtitles and editing video. No evidence of data exfiltration, malicious execution, or harmful prompt injection was found.
Capability Assessment
Purpose & Capability
The skill's behavior (upload video → cloud render → download result) matches the stated subtitle-generation purpose and the single credential (NEMO_TOKEN) is appropriate for that. However, the name includes 'Chrome Extension' while the skill is instruction-only and not actually a browser extension; the SKILL.md also declares a config path (~/.config/nemovideo/) that is not present in the registry-level requirements list — an internal metadata inconsistency.
Instruction Scope
Runtime instructions are focused on the described task: check/obtain NEMO_TOKEN, create a session, upload video files, use SSE for edits, poll for render completion, and return download URLs. The instructions do not direct the agent to read unrelated system files or exfiltrate unrelated secrets. They do instruct deriving a platform header from possible install paths (which requires inspecting common skill install locations), but this is limited and explained.
Install Mechanism
No install spec or remote downloads are present (instruction-only), so nothing is written to disk by an installer. This is the lower-risk category for install mechanisms.
Credentials
Only one credential is required (NEMO_TOKEN), which is proportional to a cloud API integration. The skill will also POST to an anonymous-token endpoint to mint a token if none is present and treat the returned token as NEMO_TOKEN. That behavior is consistent with anonymous access but means the agent will make network calls to obtain and use credentials automatically. There is a metadata mismatch about configPaths between SKILL.md and the registry summary.
Persistence & Privilege
always is false and model invocation is enabled (normal). The skill stores session_id for its own operations and does not request system-wide privileges or modify other skills' configs in the instructions.
