What problem does it solve?

This Skill streamlines the creation, validation, and maintenance of YARA-X rules by enforcing consistent metadata, naming, and performance practices, reducing false positives and deployment risk.

Core Features & Use Cases

  • Linting and metadata validation using yara-lint.py and yr check to catch syntax, metadata gaps, and anti-patterns.
  • Reference and module guidance for CRX (Chrome extensions) and DEX (Android) analysis, plus performance-oriented rule design.
  • Structured templates and best-practices for scalable rule development across PE, CRX, and DEX targets with production-grade testing.

Quick Start

Write a YARA-X rule and run the linting and validation workflow to ensure proper metadata, naming, and atom quality before deployment.
