Usage Guidance
This skill will upload your video files and session tokens to an external service (mega-api-prod.nemovideo.ai) for processing. That is necessary for a cloud render pipeline but means your videos and metadata leave your machine — do not use it for sensitive or private footage unless you trust the service. Note the SKILL.md asks the agent to auto-generate and store anonymous tokens and to read the skill frontmatter and certain install paths; those behaviors are not dangerous by themselves but are broader filesystem access than strictly required. Also: the registry metadata you provided omits the config path that the SKILL.md references — ask the skill author to explain the discrepancy, confirm the service operator and privacy policy, and verify where tokens/session data are stored and how long they are retained. If you want to limit risk, prefer a skill tied to a known vendor or require explicit consent before uploading each file rather than automatic session token creation.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-generator-canva
Version: 1.0.0
The skill automates video subtitling via a third-party service (nemovideo.ai) but includes instructions in SKILL.md that minimize user visibility and oversight. It directs the agent to automatically acquire 'anonymous' tokens, hide raw API responses and credentials from the user, and—most critically—internally process 'tool calls' or results received from the remote SSE stream without forwarding them to the user. While these behaviors support the stated cloud-based functionality, they establish a non-transparent execution environment where a remote backend could potentially influence agent behavior or access data without explicit user consent.
Capability Assessment
Purpose & Capability
Name and description claim cloud subtitle generation and burning-in video captions. The only required credential (NEMO_TOKEN) and the API endpoints referenced in SKILL.md align with that purpose — uploading videos and rendering on a remote GPU service is expected.
Instruction Scope
Instructions direct the agent to upload user-provided video files to an external API and to persist a session_id/token for subsequent calls — expected for a cloud render service. However, the skill also instructs the agent to read its own YAML frontmatter and to detect an install path (examining ~/, ~/.clawhub, ~/.cursor paths) to set an X-Skill-Platform header. Reading install paths is broader filesystem access than strictly needed for subtitle generation and is worth flagging as unnecessary scope.
Install Mechanism
This is an instruction-only skill with no install spec and no code files. Nothing will be written to disk by an installer step in the skill bundle itself, which minimizes install-time risk.
Credentials
The skill requires a single credential (NEMO_TOKEN), which is coherent. Concerns: SKILL.md instructs creating/storing anonymous tokens automatically if none exist (the skill will obtain an auth token from an external endpoint), and it references a config path (~/.config/nemovideo/) in the frontmatter. The registry metadata you supplied lists no required config paths while the SKILL.md includes one — this mismatch is inconsistent. Additionally, the skill will transmit user video data and session tokens to an external service (mega-api-prod.nemovideo.ai), which is expected for cloud processing but is a privacy/exfiltration consideration.
Persistence & Privilege
always is false and model invocation is allowed by default. The skill expects to store a session_id and token for the session lifecycle, which is normal for this type of service. The skill does not request elevated platform privileges or permanent 'always' inclusion.
How to Use
