Security Scan

The skill and its files are internally consistent with an image-generation client for Volcengine (Jimeng); the requested binaries and env vars match the declared purpose and there is no unexplained access or suspicious install behavior.

Purpose & Capability

Name/description match the implementation: the skill is a Node.js client for Volcengine '即梦' image-generation (jimeng) and correctly requires node and the service Access/Secret keys. Required items (node, JIMENG_ACCESS_KEY, JIMENG_SECRET_KEY) are proportionate and expected.

Instruction Scope

SKILL.md instructs running the included Node script which reads only the declared env vars, sends prompts/optional image URLs to the official visual.volcengineapi.com endpoints, polls for results, and can save returned images to disk. The script makes network requests to the vendor and to image URLs returned by the service (for downloads) — this is expected for the stated purpose.

Install Mechanism

No install spec and the package is implemented as a single Node script using only built-in Node modules (crypto, https, fs, etc.). Nothing is downloaded from arbitrary or obscure URLs and no archive extraction or package manager installs are required.

Credentials

Only two env vars are required (ACCESS and SECRET) which are exactly the credentials needed to sign requests to the service. No unrelated secrets or system credentials are requested.

Persistence & Privilege

The skill does not request always:true, does not modify other skills or system settings, and is user-invocable. It runs on-demand and does not demand persistent elevated privileges.

Assessment

This skill appears to be a straightforward Node.js client for Volcengine '即梦' image generation. Before installing/using: 1) Understand that all prompts and any image URLs you supply will be sent to volcengine (visual.volcengineapi.com) and the generated images will be downloaded — do not send private or sensitive images or prompts you do not want sent to an external service. 2) Provide dedicated API keys with the minimum necessary privileges and monitor usage/billing (the service bills per output image). 3) The script will write files to disk when you use --save; run it in a directory you control. 4) Review the included scripts yourself (they are present and human-readable) before running. 5) If you need stronger assurance about provenance, obtain the skill from a known publisher or the official vendor SDK rather than an unknown source.

参数说明

提示词（二选一）

参数	说明
--prompt	通用文生图提示词，中英文均可，最长 800 字符
--text	字体设计模式：图片上显示的文字
--color	字体设计模式：背景主色调（默认: 蓝色）
--illustration	字体设计模式：配饰元素，逗号分隔

分辨率（三选一，不传默认 2K 自动比例）

参数	说明
--ratio	比例预设（见 ratios 命令），如 16:9、4:3、1:1、16:9-4k
--width + --height	精确宽高（需同时传）
--size	像素面积，如 4194304（2K）、16777216（4K）

图生图

参数	说明
--image-url	参考图 URL，多张用逗号分隔，最多 10 张
--scale	文本影响强度 0~1（0=完全参考图，1=完全按提示词，默认 0.5）

其他

参数	说明
--force-single	强制只生成 1 张（省钱省时，避免 AI 自动多图计费）
--save <路径>	保存图片到本地，多图自动加序号

注意事项

• 计费：按输出图片张数计费，AI 默认可能输出多张；对费用敏感时加 --force-single
• 图片 URL 有效期：24 小时，需及时下载
• 任务超时：最长等待 120 秒，超时后可用 task_id 手动查询
• 内容审核：提示词含敏感词会被拦截（code 50412/50413），修改提示词后重试
