privacy-mask

Privacy Mask

Detect and mask sensitive information in images locally before they leave your machine.

Prerequisites

This skill requires the privacy-mask CLI to be pre-installed on the system. If it is not available, inform the user that they need to install it first:

1. Install via pip: pip install privacy-mask
2. Ensure Tesseract OCR is installed: brew install tesseract (macOS) or apt install tesseract-ocr (Linux)
3. Verify installation: privacy-mask --version
4. (Optional) Install NER support: pip install privacy-mask[ner]

When to use

• User sends a screenshot or image file (.png, .jpg, .jpeg, .bmp, .tiff) that may contain private data
• User mentions privacy, masking, redacting, or anonymizing
• You need to analyze an image but want to redact sensitive info first
• IF the user shares a screenshot for debugging, THEN run privacy-mask mask <path> --dry-run first to check for PII
• IF detections are found, THEN mask the image before proceeding with analysis

Usage

Mask an image:

privacy-mask mask /path/to/screenshot.png
privacy-mask mask /path/to/screenshot.png --in-place
privacy-mask mask /path/to/screenshot.png --dry-run   # detect only, no masking
privacy-mask mask /path/to/screenshot.png --detection-engine regex  # regex only, skip NER
privacy-mask mask /path/to/screenshot.png --config /path/to/custom-config.json
