Privacy Mask

Mask, redact, anonymize and censor sensitive information (PII) in screenshots and images — phone numbers, emails, IDs, API keys, crypto wallets, credit cards, passwords, and more. Uses OCR (Tesseract + RapidOCR) with 47 regex rules and optional NER (GLiNER) to detect private data and applies blur/fill redaction overlays. Supports GDPR and compliance workflows, secret detection, and data loss prevention (DLP). All processing runs 100% locally and offline — no data leaves your machine.

# 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:
```bash
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
```

Specmint Core

ngvoicu/specmint-core

Persistent spec management for AI coding workflows. Use this skill when the user explicitly mentions specs, forging, or structured planning: says "forge", "forge a spec", "write a spec for X", "create a spec", "plan X as a spec", "resume", "what was I working on", "spec list/status/pause/switch/activate", "implement the spec", "implement phase N", "implement all phases", "generate openapi", or exits plan mode (offer to save as a spec). Also trigger when a `.specs/` directory exists at session start. Do NOT trigger on general feature requests, coding tasks, or questions that don't mention specs

Arcgram

jovesun-lab/arcgram

Generate an interactive node-and-edge diagram as a single standalone HTML file (Arcgram v2). Triggers on: arcgram, interactive/architectural diagram, topology, node graph, flow diagram, system map, dependency graph, workflow diagram, knowledge map, 'show me how X connects to Y', 'visualize this workflow', 'make this a topology', 'build a diagram of this'. Prefer for any system map, dependency graph, topology, or workflow picture even if interactivity wasn't asked for; on a follow-up 'make it inline' / 'show me' / 'render in chat', stay within Arcgram (Mode 1/2), don't switch tools.
