Usage Guidance
This skill will send any video/audio files you provide to an external service at mega-api-prod.nemovideo.ai and requires a bearer token (NEMO_TOKEN) to operate; it can also obtain a short-lived anonymous token itself. Before installing or using it: (1) confirm you trust the service and owner (source/homepage is unknown), (2) do not upload sensitive or private footage unless you accept third‑party processing, (3) be aware the agent will read its own skill metadata and may inspect install paths (the SKILL.md references ~/.config/nemovideo/ even though registry metadata did not), and (4) if you want stronger guarantees, ask the publisher for a privacy policy, official homepage, or source code so you can verify where files and tokens are stored and how long they are retained.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-maker-online
Version: 1.0.0
The skill bundle provides instructions for an AI agent to interface with a cloud-based video subtitling service (nemovideo.ai). It includes standard API integration logic for authentication, session management, and file processing. While it instructs the agent to detect its installation path for platform attribution and requires a service-specific token (NEMO_TOKEN), these actions are consistent with the stated functionality and do not exhibit signs of malicious intent, data exfiltration, or unauthorized execution.
Capability Assessment
Purpose & Capability
Name/description (subtitle generation and burn-in) match the runtime instructions: uploading videos, creating a session, streaming SSE edits, and requesting a bearer token (NEMO_TOKEN). The single required credential (NEMO_TOKEN) is appropriate for an external rendering API.
Instruction Scope
Instructions explicitly direct the agent to upload user video/audio files and stream edits to mega-api-prod.nemovideo.ai, obtain/store session IDs and tokens, and stream SSE responses to the user. This is expected for the stated purpose but does mean user media and associated metadata will be transmitted to a third-party service; the skill also instructs reading its own frontmatter and detecting install path to set attribution headers (requires checking local skill/filesystem).
Install Mechanism
No install spec or external downloads — instruction-only skill (lowest install risk).
Credentials
The skill declares a single primary env var (NEMO_TOKEN), which fits the API usage. There is a small inconsistency: the SKILL.md frontmatter lists a config path (~/.config/nemovideo/) while the registry metadata summary indicated no required config paths; it's unclear whether the skill expects to read or write that config directory.
Persistence & Privilege
The skill is not always-enabled and does not request system-wide privileges. It asks to save session tokens and session_id for operation, which is normal for a remote-processing skill.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install subtitle-maker-online - After installation, invoke the skill by name or use
