Security Scan

The skill's code, dependencies, and instructions are consistent with an offline image-processing tool (compression, background removal/replacement, upscaling); nothing in the bundle requests unrelated credentials or network endpoints.

Purpose & Capability

The name/description match the included code: index.js implements compress, remove background, replace background, and upscale. Dependencies (@imgly/background-removal-node, sharp) are appropriate for the stated features. Minor metadata inconsistencies exist (package.json/package-lock/package bin name mismatch and SKILL.md references @imgly/background-removal vs @imgly/background-removal-node), but these are documentation/packaging issues rather than indicators of hidden behavior.

Instruction Scope

SKILL.md and CLI instruct the agent to read input image files and write output image files, and to call the exported functions. The code only reads/writes paths supplied by the user and calls a local background-removal library; it does not access unrelated system files, environment variables, or external HTTP endpoints in the provided files.

Install Mechanism

There is no platform install spec in the registry metadata, but the package includes package.json and package-lock.json indicating an npm install is expected. Dependencies are fetched from the public npm registry (registry.npmjs.org) which is standard; @imgly/background-removal-node and onnxruntime-node will pull native binaries. This is expected for local ML/image processing but means native binaries will be downloaded/installed at npm install time and Node >=18 is required.

Credentials

The skill does not request environment variables, credentials, or config paths. All operations are file-based and proportional to the declared purpose.

Persistence & Privilege

The skill does not request persistent platform privileges (always:false). It does not modify other skills or system configurations in the provided files. Autonomous invocation is allowed by default (normal), but that is not combined with any elevated privileges or broad credential access.

Assessment

This skill appears to be what it claims (an offline image-processing tool). Before installing, consider: (1) npm install will download native binaries (sharp, onnxruntime-node) — ensure you run this in an environment where installing native modules is acceptable and Node >=18 is available; (2) verify the @imgly/background-removal-node package source and license if you need vendor trust; (3) the package and lockfile show small metadata inconsistencies (different package/bin names in places) — these are likely packaging/documentation issues but you may want to confirm the intended CLI name and package identity; (4) the tool reads and writes any file paths you pass it — avoid giving it sensitive files/paths; (5) if you need stricter assurance, run npm install and execute the code in a sandbox or review the installed dependency tree before running on production data.

Image Process Skill

This skill provides image processing capabilities including compression, background removal, background replacement, and upscaling.

Features

• Image Compression: Compress images to reduce file size with adjustable quality
• Background Removal: AI-powered background removal using @imgly/background-removal
• Background Replacement: Replace background with a custom color or another image
• Image Upscaling: Enlarge images to bigger dimensions

Usage

1. Compress Image

const { compressImage } = require('./index');

const result = await compressImage({
  input: './image.jpg',
  quality: 80,
  output: './compressed.jpg'
});

2. Remove Background

const { removeBackground } = require('./index');

const result = await removeBackground({
  input: './person.jpg',
  output: './person-nobg.png'
});

3. Replace Background

const { replaceBackground } = require('./index');

// Replace with solid color
const result = await replaceBackground({
  input: './person.jpg',
  background: '#ffffff',
  output: './result.jpg'
});

// Replace with another image
const result = await replaceBackground({
  input: './person.jpg',
  background: './background.jpg',
  output: './result.jpg'
});

4. Upscale Image

const { upscaleImage } = require('./index');

// Scale by factor (2x)
const result = await upscaleImage({
  input: './image.jpg',
  scale: 2,
  output: './upscaled.jpg'
});

// Or specify exact dimensions
const result = await upscaleImage({
  input: './image.jpg',
  width: 2000,
  height: 3000,
  output: './upscaled.jpg'
});
