Usage Guidance
This skill appears to be what it says: a thin wrapper that uploads videos to a nemo-video backend for server-side subtitle editing and rendering. Before installing, confirm: (1) you are comfortable uploading the videos (privacy/retention of content and any PII in audio/transcripts); (2) the API domain (mega-api-prod.nemovideo.ai) is trustworthy for your data; (3) where session tokens and session_id will be stored by your agent (avoid leaking tokens to logs); and (4) reconcile the small metadata mismatch (the SKILL.md frontmatter mentions ~/.config/nemovideo/). Do not provide other unrelated credentials. If you need stronger privacy, avoid uploading sensitive videos to third-party renderers.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-editor
Version: 1.0.0
The subtitle-editor skill is a legitimate integration for the NemoVideo cloud service, facilitating video captioning and rendering via remote GPU nodes. It manages authentication, file uploads, and session state through the 'mega-api-prod.nemovideo.ai' domain, which aligns perfectly with its stated purpose of server-side video processing. No indicators of data exfiltration, unauthorized local file access, or malicious prompt injection were identified in SKILL.md or the metadata.
Capability Assessment
Purpose & Capability
The skill advertises server-side subtitle editing/export and only requires a service token (NEMO_TOKEN) and API calls to a nemovideo.ai backend — these are appropriate for a remote-rendering subtitle service. Note: the SKILL.md frontmatter includes a config path (~/.config/nemovideo/) in its metadata, but the registry metadata shown earlier listed no required config paths; this discrepancy should be clarified but does not itself imply malicious intent.
Instruction Scope
Instructions direct the agent to obtain/use NEMO_TOKEN, create sessions, upload user video files, post SSE messages, and poll for render results — all expected. The doc asks the agent to auto-detect an install path to set X-Skill-Platform which could require inspecting the agent's install location; that's outside the core subtitle task and worth validating (the platform header is an attribution requirement, not a functional necessity). The instructions also tell the agent to persist a session_id/token for the session lifecycle; storing session identifiers is reasonable but confirm where/how they are stored.
Install Mechanism
No install spec and no code files (instruction-only). That minimizes filesystem changes and reduces supply-chain risk.
Credentials
Only a single credential (NEMO_TOKEN) is declared as required and is proportionate to calling the remote API. The frontmatter metadata also references a config path (~/.config/nemovideo/) which was not listed in the registry requirements — this mismatch should be reconciled. No unrelated credentials or system secrets are requested.
Persistence & Privilege
always is false (normal). The skill asks to save session identifiers and to reuse NEMO_TOKEN; this is expected for session-based remote services and does not request elevated or persistent platform privileges.
