Description
Resize images using ImageMagick (CLI). Entrypoint is a Bash script.
README (SKILL.md)

Overview

This skill provides a single executable script scripts/resize.sh that the agent (or the openclaw CLI) can call to resize an image with ImageMagick.

Installation (manual)

Copy the folder into your OpenClaw skills directory, e.g.:

cp -r resize-magic ~/.openclaw/skills/resize-magic

# or install via CLI if available
openclaw skill install ./resize-magic
Usage Guidance
This skill appears to do exactly what it says: run ImageMagick to resize a file. Before installing, review and accept that it will run the ImageMagick binary on any file you pass to it. Important cautions: ImageMagick has historically had vulnerabilities (e.g., "ImageTragick") when processing untrusted or maliciously crafted images — keep ImageMagick up to date and consider hardening its policy.xml if you will process files from untrusted sources. The provided script is simple and readable; if you plan to use it in automation, run it with least privilege and test on benign images first. If you have any additional environment or deployment constraints (e.g., no Homebrew on your host), confirm the install step matches your environment.
Capability Analysis
Type: OpenClaw Skill Name: Developer: Version: Description: OpenClaw Agent Skill Suspicious High-Entropy/Eval files: 1 The skill is designed to resize images using ImageMagick. The `SKILL.md` clearly defines the skill's purpose and usage, without any prompt injection attempts. The core script `scripts/resize.sh` properly handles arguments, checks for input file existence, and most importantly, includes an explicit check to prevent shell injection by filtering suspicious characters from the `geometry` parameter before executing ImageMagick commands. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or other high-risk behaviors.
Capability Assessment
Purpose & Capability
Name/description match the code and install: the script simply calls ImageMagick (magick/convert) to resize images; the brew install of imagemagick is appropriate and proportional.
Instruction Scope
SKILL.md and the entrypoint are narrowly scoped to running the resize script. The instructions do not read unrelated files, environment variables, or send data to external endpoints; the script only reads the input file and writes the output file.
Install Mechanism
Install uses a standard Homebrew formula (imagemagick) which is an expected and low-risk way to obtain the required binaries. No arbitrary downloads or extraction from untrusted URLs are used.
Credentials
No credentials, environment variables, or config paths are requested. The required binaries listed (bash, magick/convert) are proportional to the stated purpose.
Persistence & Privilege
The skill is user-invocable and not forced-always; it does not request persistent elevated privileges or modify other skills' configs. Autonomous invocation is allowed (platform default) but not excessive here.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install image-magik-resize
  3. After installation, invoke the skill by name or use /image-magik-resize
  4. Provide required inputs per the skill's parameter spec and get structured output
