Description
Skip the learning curve of professional editing software. Describe what you want — add subtitles in English and Spanish to my video — and get captioned video...
Usage Guidance
This skill appears to implement a cloud subtitle/upload workflow and only needs one token (NEMO_TOKEN), which is reasonable. Before installing, ask or confirm: (1) whether the skill will read or write files under ~/.config/nemovideo/ (the frontmatter references that path but the registry did not), (2) how and where the anonymous token (if auto‑created) and session IDs are stored and how long they're retained, and (3) that uploaded videos will be sent to https://mega-api-prod.nemovideo.ai (verify you trust that service). If you don't want tokens stored locally, decline or remove the skill or ensure the agent only accepts a token provided at runtime. Because of the config-path metadata mismatch and implicit local token storage, treat this as suspicious until the developer clarifies storage behavior and the exact need for the config path.
Capability Analysis
Type: OpenClaw Skill
Name: subtitle-generator-for-video
Version: 1.0.0
The skill is a legitimate integration for a cloud-based video processing service hosted at nemovideo.ai. It provides instructions for an AI agent to handle authentication, session management, file uploads, and video rendering via a series of documented API endpoints (e.g., mega-api-prod.nemovideo.ai). The behavior is consistent with the stated purpose of generating subtitles, and there is no evidence of data exfiltration, malicious code execution, or harmful prompt injection.
Capability Assessment
Purpose & Capability
The skill's name and description align with an online subtitle/encoding service and the single required credential (NEMO_TOKEN) is consistent with calling a third‑party API. However, the SKILL.md frontmatter lists a local config path (~/.config/nemovideo/) while the registry metadata above says 'Required config paths: none' — this mismatch is unexplained and could indicate the skill expects to read or store local credentials/config even though the registry didn't declare it.
Instruction Scope
Instructions tell the agent how to obtain an anonymous token, create and store session IDs, upload local files (multipart -F "files=@/path"), open SSE streams, poll render status, and include attribution headers. All of those are reasonable for a cloud video processing skill, but they include steps that read/upload user files and may store/use tokens locally. The guidance to 'not display raw API responses or token values' shows awareness of secrets, but the SKILL.md does not clearly define where/how tokens/session IDs are stored and whether any local config is read/written (the referenced config path increases that uncertainty).
Install Mechanism
There is no install spec and no code files — the skill is instruction-only, which minimizes install risk (nothing is downloaded or written by an installer).
Credentials
Only one environment variable (NEMO_TOKEN) is declared as required and is appropriate for a third‑party subtitle service. The SKILL.md also documents a fallback flow to obtain an anonymous token automatically; that is proportionate but implies the skill will generate, store, and reuse credentials. The implicit expectation to access or populate ~/.config/nemovideo/ (per frontmatter) is not justified by the registry metadata and should be clarified.
Persistence & Privilege
The skill is not always-enabled and doesn't request elevated or platform-wide privileges. Autonomous invocation is allowed (normal default). The only persistence concern is potential local storage of short‑lived tokens/session IDs — the SKILL.md does not explain storage location or retention policy.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install subtitle-generator-for-video - After installation, invoke the skill by name or use
/subtitle-generator-for-video - Provide required inputs per the skill's parameter spec and get structured output
