Security Scan

The skill appears to implement the claimed video-generation features and accesses only the expected provider APIs, but its declared requirements (notably curl/jq) and some metadata don't match the actual code, which is an inconsistent signal you should review before installing.

Purpose & Capability

The script implements Luma, Runway, and Kling video generation and only needs an API key per platform. However, the skill metadata and registry list required binaries 'curl' and 'jq' even though the provided Python script uses urllib and base64 and does not call curl/jq. This mismatch is unnecessary for the stated purpose and suggests sloppy metadata or possible leftover requirements from a different implementation.

Instruction Scope

SKILL.md instructs the agent to run the included Python script and to supply an API key either via --api-key or environment variables. The instructions do not request unrelated system files, other credentials, or exfiltration endpoints; network calls are only to the named provider APIs.

Install Mechanism

There is no install spec (instruction-only skill with a bundled script). Nothing is downloaded at install time and no installers or arbitrary remote archives are referenced. Risk from installation is low.

Credentials

The code expects per-platform API keys (LUMA_API_KEY, RUNWAY_API_KEY, KLING_API_KEY), which are proportionate to the skill's function. Registry metadata shows no required env vars but SKILL.md lists these as optional — practically, the script will fail unless an API key is provided for the chosen platform, so you must supply those keys. No other credentials are requested.

Persistence & Privilege

The skill is not always-enabled and does not request elevated persistence. It does write output files (videos) to paths you provide, which is expected behavior.

What to consider before installing

Before installing: (1) Understand you will need a valid API key for whichever provider you use (Luma/Runway/Kling); the script will send your key to those provider endpoints to create and download videos. (2) The skill metadata unnecessarily lists curl and jq even though the bundled Python script doesn't use them — this mismatch is not by itself malicious but is sloppy and worth asking the publisher to clarify or fixing locally. (3) Review the provider URLs in the script if you need to verify they are official endpoints. (4) Be careful with filenames/paths you pass (the script writes files to disk). (5) If you do not trust the unknown source owner, consider running the script in a sandboxed environment or inspect/modify the code (e.g., remove or correct metadata) before use.

工作流

1. 草稿：先用短 prompt 生成 5 秒视频测试
2. 迭代：调整 prompt 直到满意
3. 最终：生成 10 秒高清版本

常见错误

• Error: No API key provided → 设置环境变量或传递 --api-key
• Error: Quota exceeded → API 额度用尽，等待重置或换平台
• Error: Invalid prompt → prompt 太短或包含敏感词
