Description
Turn a 2-minute green screen presentation clip into 1080p captioned green screen videos just by typing what you need. Whether it's adding subtitles to green...
Usage Guidance
Before installing or enabling this skill: 1) Confirm the domain (mega-api-prod.nemovideo.ai) is the official service you expect and check their privacy/retention policy—your video files are uploaded to that domain. 2) Ask where the skill will store the anonymous token and session_id (in-memory only vs. written to ~/.config/nemovideo/) and how long those credentials are kept. 3) Decide whether you want the skill to auto-create anonymous tokens on your behalf; if not, pre-provision NEMO_TOKEN and deny auto-creation. 4) Be aware the instructions intentionally hide raw API responses and tokens from the user—request transparency (logs, job IDs) if you need auditability. 5) If you have sensitive content, avoid uploading it until you confirm the vendor, storage/retention, and access controls.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-generator-green-screen
Version: 1.0.0
The skill is a legitimate integration for a video processing service hosted at nemovideo.ai. It implements standard API authentication (anonymous token generation), session management, and file upload/rendering workflows. The instructions in SKILL.md are consistent with the stated purpose of generating subtitles for green screen videos and do not attempt to exfiltrate sensitive data, execute unauthorized commands, or hide malicious behavior. All network activity is directed to the service's production API (mega-api-prod.nemovideo.ai).
Capability Assessment
Purpose & Capability
The skill claims to add subtitles and export composited green-screen videos and only requires a NEMO_TOKEN to talk to a nemo video backend—this is coherent. However, the SKILL.md YAML declares a required config path (~/.config/nemovideo/) while the registry metadata shown earlier listed no required config paths. That mismatch is an internal inconsistency worth confirming.
Instruction Scope
The runtime instructions are explicit about creating a session, uploading user video files to https://mega-api-prod.nemovideo.ai, streaming SSE responses, and polling render status. These actions are expected for a cloud render/subtitle service. Two things to notice: (1) if NEMO_TOKEN is not present the skill will automatically POST to an anonymous-token endpoint and treat the returned token as NEMO_TOKEN (i.e., it will acquire credentials on the user's behalf); (2) the doc says 'Don't display raw API responses or token values to the user,' which is reasonable for hiding secrets but also reduces transparency—ask how and where tokens/session IDs are stored and for what retention period. The instructions also derive platform headers by inspecting install paths (~/.clawhub/, ~/.cursor/skills/), which implies the agent will read its environment/paths to compute headers.
Install Mechanism
No install spec and no code files — this is instruction-only. That is low risk from an installation standpoint because nothing arbitrary will be downloaded or written by an installer step described here.
Credentials
Only NEMO_TOKEN is declared as a required environment variable, which is proportionate to a cloud API integration. Caveats: the skill will create an anonymous token if none is present (it expects to store that token and session_id for subsequent requests). Also the SKILL.md metadata references a local config path (~/.config/nemovideo/) which suggests the skill may read/write a config file in the user's home directory—this should be verified and justified.
Persistence & Privilege
always:false (normal). The instructions instruct the agent to persist an anonymous token and session_id for subsequent requests and reference a potential config path. Persisting tokens/sessions and writing a config under ~/.config/nemovideo/ are legitimate for a client that resumes jobs, but this is additional persistence and should be disclosed. There's no evidence the skill modifies other skills or system-wide settings.
How to Use
