Usage Guidance
This skill will upload your videos to a third‑party service and either use an existing NEMO_TOKEN or create and store an anonymous token for you. Before installing: 1) Confirm the service domain (mega-api-prod.nemovideo.ai) and owner — there's no homepage or source link in the registry. 2) Decide whether you want your videos sent to an external service (don't upload sensitive content). 3) Ask the developer where tokens/session state are stored (env var vs disk) and whether the config path (~/.config/nemovideo/) will be read/written. 4) Prefer supplying your own service token rather than allowing automatic anonymous token creation if you need control over retention/consent. 5) If you proceed, monitor what the skill stores (agent state or config files) and revoke any anonymous token/credits when done.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-video-online
Version: 1.0.0
The skill bundle provides a legitimate interface for a video subtitling service hosted at mega-api-prod.nemovideo.ai. The SKILL.md file contains standard instructions for an AI agent to handle authentication via tokens, manage user sessions, and interact with cloud-based GPU rendering endpoints. No evidence of data exfiltration, malicious command execution, or harmful prompt injection was found; the requested access to ~/.config/nemovideo/ and the NEMO_TOKEN environment variable is consistent with the stated purpose of the tool.
Capability Assessment
Purpose & Capability
The skill's name/description match the actions in SKILL.md: it uploads videos, requests subtitles, and exports rendered MP4s from a remote service. The declared primary env var (NEMO_TOKEN) is appropriate for that purpose. However, registry metadata says no required config paths while the SKILL.md frontmatter includes a config path (~/.config/nemovideo/) — that mismatch is unexpected and should be clarified.
Instruction Scope
Instructions will upload user video files and interact with an external API (mega-api-prod.nemovideo.ai). The skill instructs the agent to generate an anonymous token if NEMO_TOKEN is not present and to 'store' the token and session_id for subsequent requests; it is unclear where/how tokens or session state should be persisted (environment, agent memory, or disk). The SKILL.md also requires reading/writing a config path in frontmatter — reading or writing user config files is scope creep for a simple subtitle helper and is not documented in the registry metadata.
Install Mechanism
This is instruction-only with no install spec or code files, so nothing is written to disk by an installer. That minimizes install-time risk but also means there is no code to audit beyond the instructions.
Credentials
Only a single credential (NEMO_TOKEN) is declared, which is proportionate to a third‑party API client. But SKILL.md describes obtaining an anonymous token automatically and storing it, and frontmatter mentions a config path — these behaviors imply the skill may read/write credentials or config in the user's environment without explicit consent. Also the service will receive full video files, so the privacy implications are material.
Persistence & Privilege
The skill is not always-enabled and doesn't request elevated platform privileges. However, it instructs the agent to persist the anonymous token and session_id and references a per-user config directory (~/.config/nemovideo/) — that implies persistent storage of credentials/state which should be documented and consented to. Autonomous invocation is allowed (platform default) which increases the impact if persistence is misused.
How to Use
