/install vertical-video
Description
Get vertical MP4 clips ready to post, without touching a single slider. Upload your horizontal video footage (MP4, MOV, AVI, WebM, up to 500MB), say somethin...
Usage Guidance
This skill appears to do what it says: it uploads your videos to a third‑party service (mega-api-prod.nemovideo.ai) and returns reformatted MP4s. Before installing: (1) confirm you are comfortable uploading video content to that domain; (2) decide whether to provide your own NEMO_TOKEN (from a trusted account) or allow the skill to create an anonymous token — anonymous tokens are short‑lived but still grant the service access to uploaded media; (3) check whether session/token data will be stored on disk (~/.config/nemovideo/) if you want to avoid local persistence; (4) avoid supplying unrelated secrets. If any of these are unacceptable, do not enable the skill.
Capability Analysis
Type: OpenClaw Skill
Name: vertical-video
Version: 1.0.0
The skill is a legitimate tool designed to interface with the nemovideo.ai API for cloud-based video reformatting. It handles authentication via environment variables or anonymous token generation and manages video processing through standard REST and SSE endpoints. No evidence of data exfiltration, malicious execution, or harmful prompt injection was found; all behaviors are consistent with the stated purpose of converting videos for social media platforms.
Capability Assessment
Purpose & Capability
Name/description (convert horizontal video to vertical MP4) match the declared API calls, upload endpoints, SSE stream usage, and the single required credential (NEMO_TOKEN). Asking for an API token and session management is appropriate for a cloud render service.
Instruction Scope
SKILL.md focuses on uploading videos, starting render jobs, polling state, and returning download URLs. It does not instruct reading unrelated system files or harvesting other credentials. It does instruct automatic anonymous-token creation if NEMO_TOKEN is absent, which is consistent with establishing per-session access to the backend.
Install Mechanism
Instruction-only skill with no install spec or code files; nothing is written to disk by an installer. This minimizes risk and is proportional to the described functionality.
Credentials
Only one env var (NEMO_TOKEN) is required, which is appropriate. The skill also instructs creating an anonymous token via the service if none is present. Metadata lists a config path (~/.config/nemovideo/) which is plausible for persisting session state, but the SKILL.md does not explicitly describe writing to that path — a minor inconsistency to be aware of.
Persistence & Privilege
always:false and normal model invocation — expected. The skill mentions storing session_id and includes a config path in metadata; while storing session info locally (or in agent storage) is reasonable, users should be aware tokens/sessions might be persisted for later use.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install vertical-video - After installation, invoke the skill by name or use
/vertical-video - Provide required inputs per the skill's parameter spec and get structured output
