Usage Guidance
This skill will upload your video files to an external service (mega-api-prod.nemovideo.ai) and requires/provides a bearer token (NEMO_TOKEN). Before installing or invoking: 1) Verify you trust the remote domain/operator and find a privacy/retention policy — there's no homepage provided here. 2) Understand that the skill will read its own frontmatter and probe common install paths in your home directory to set an attribution header — if you don't want local path metadata exposed, don't install. 3) If you don't already have a NEMO_TOKEN, the skill will request an anonymous token from the backend automatically (100 free credits, 7-day expiry) — consider whether you want an unknown service to mint and manage tokens for you. 4) Avoid uploading sensitive or confidential video content until you confirm the service's storage/retention practices. 5) The registry metadata inconsistently omits the config path that SKILL.md references; ask the publisher for clarification (or a homepage) before use. If you are uncomfortable, do not install or use the skill and consider running a network/traffic inspection or using a sandbox to test its behavior first.
Capability Analysis
Type: OpenClaw Skill
Name: video-to-mp3
Version: 1.0.0
The skill provides a functional interface for a video-to-MP3 conversion service hosted at nemovideo.ai. It includes standard API interaction logic, such as session management, token acquisition (including an anonymous flow), and error handling. While it performs basic environment discovery to set attribution headers (checking for ~/.cursor or ~/.clawhub paths), its behavior is consistent with its stated purpose and lacks indicators of malicious intent or unauthorized data exfiltration.
Capability Assessment
Purpose & Capability
The skill's stated purpose (upload a video, extract MP3 via a cloud backend) aligns with the single required credential (NEMO_TOKEN) and the API endpoints in SKILL.md. However, registry metadata lists no config paths while the SKILL.md frontmatter and runtime instructions reference a config path (~/.config/nemovideo/) and require reading the SKILL.md frontmatter — an inconsistency between declared registry requirements and the runtime instructions.
Instruction Scope
Instructions tell the agent to upload user video files (up to 500MB) to https://mega-api-prod.nemovideo.ai, create sessions, poll SSE endpoints, and include attribution headers. They also instruct the agent to read this skill's YAML frontmatter and detect install paths (~/.clawhub/, ~/.cursor/skills/) to set X-Skill-Platform. Those file-system reads are not declared in the registry and expand the scope beyond just 'send this file to an API.'
Install Mechanism
No install spec and no code files — instruction-only. This is the lowest install risk because nothing is written to disk by an installer.
Credentials
Only one required environment variable is declared (NEMO_TOKEN), which is proportionate to a cloud service. However SKILL.md also describes obtaining an anonymous token by POSTing to an auth endpoint if NEMO_TOKEN is missing (it will mint a short-lived anonymous token). The registry declares NEMO_TOKEN as required but the instructions will generate one if absent — this mismatch should be noted. There are no other unrelated credentials requested.
Persistence & Privilege
The skill does not request always:true, does not modify other skills, and does not require persistent system-level privileges. It creates and uses ephemeral sessions on the backend, which is consistent with its purpose.
