Pixmind Image Compress

Security checks across malware telemetry and agentic risk

Overview

This skill is a cloud image-compression tool that uploads user-selected images to Pixmind/Tencent Cloud and saves compressed copies locally.

Install only if you are comfortable sending the images you choose to Pixmind/Tencent Cloud for processing. Use a dedicated, revocable Pixmind API key, avoid broad recursive folders unless intended, and do not process confidential screenshots, IDs, medical images, or regulated business material without checking the provider's privacy terms.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The skill markets itself as cloud-powered and says local files are converted to Base64 for upload, but it does not prominently warn users that their local images are transmitted to a third-party service. This can lead to unintentional disclosure of sensitive photos, screenshots, documents, or metadata-bearing images when users believe processing is effectively local or low-risk.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
This code base64-encodes local image files and sends their full contents to a remote API for processing, but the CLI help and runtime behavior do not clearly warn users that local files are uploaded off-device. In a compression tool this is functionally expected, but the lack of explicit disclosure creates a privacy and data-handling risk, especially for sensitive personal or corporate images.
