Usage Guidance
This skill appears to do what it says: it uploads videos to nemovideo.ai and uses a single service token (NEMO_TOKEN). Before installing, consider: 1) Privacy — your video files will be sent to an external cloud service; do not upload sensitive content. 2) Token handling — the skill will try to create an anonymous token automatically if NEMO_TOKEN is not set; ask for user consent before that happens and prefer short-lived or limited-scope tokens. 3) Metadata mismatch — the SKILL.md mentions a config path (~/.config/nemovideo/) that the registry listing does not; ask the publisher to clarify why and what is stored there. 4) Source verification — there is no homepage/source repo; if possible verify the service provider (nemovideo.ai) and terms of service. 5) Testing — try with non-sensitive test videos first and revoke any token you created if you no longer need it.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-generator-best
Version: 1.0.0
The 'subtitle-generator-best' skill is a legitimate integration for the NemoVideo AI cloud service, designed to automate video subtitling and editing. It provides the AI agent with detailed instructions for managing authentication via the 'NEMO_TOKEN', handling sessions, and interacting with the 'mega-api-prod.nemovideo.ai' backend. While it requires the agent to perform network requests and manage local configuration in '~/.config/nemovideo/', these actions are strictly aligned with its stated purpose and do not exhibit signs of malicious intent, data exfiltration, or unauthorized execution.
Capability Assessment
Purpose & Capability
Name/description (generate and embed subtitles) align with the instructions: the SKILL.md describes uploading video files and calling a remote rendering/subtitling API (mega-api-prod.nemovideo.ai) and uses a single service token (NEMO_TOKEN). The requested environment variable (NEMO_TOKEN) is appropriate for a cloud backend. No unrelated credentials or binaries are requested.
Instruction Scope
Instructions are focused on session creation, uploading media, SSE-driven editing, and export polling — all consistent with the stated purpose. Important: the skill will upload user-provided video files to the external service and may automatically obtain an anonymous token if NEMO_TOKEN is not present. It also requires that specific attribution headers be added to every request. The SKILL.md tells the agent to 'not expose tokens or raw API output', which is good, but automatic network calls and token creation are effectively autonomous actions and should be disclosed to the user before running.
Install Mechanism
Instruction-only skill with no install spec and no code files — the lowest disk/write risk. All heavy work occurs on the remote API; nothing is downloaded or installed locally by the skill.
Credentials
Only one credential (NEMO_TOKEN) is declared and used, which matches the cloud API workflow. However, SKILL.md frontmatter includes a configPaths entry (~/.config/nemovideo/) while the registry metadata listed no required config paths — this metadata mismatch should be resolved. Also note the skill contains logic to obtain an anonymous NEMO_TOKEN by POSTing to an external endpoint if the token is missing, which means the agent may create and use credentials automatically.
Persistence & Privilege
always:false and no install actions. The skill does not request system-wide privileges or claim to modify other skills. Autonomous invocation is allowed (platform default) but is not combined with unusually broad credential access or persistent presence.
