How to write better YARA rules?▼

Why is my YARA rule slow?▼
The skill diagnoses performance problems like short atoms, unanchored regex, and expensive calculations placed early in conditions, then suggests concrete fixes.
Can it check if a YARA rule actually works?▼
Yes. It runs every rule through a YARA-X validation script and applies 20+ yaraQA checks to catch rules that would never match or fail to compile.

No. Just paste a rule or describe what you want to detect in plain English, and the skill handles syntax, optimization, and validation for you.
