Optimizes JetBrains IDE performance by generating tailored VM options for memory management and garbage collection based on specific JDK versions.

The JetBrains VM Options skill provides expert-level guidance for configuring JetBrains IDEs such as IntelliJ IDEA, PyCharm, and WebStorm for peak performance. By analyzing the specific IDE version and JDK environment (17 or 21), it generates optimized .vmoptions configurations that address memory allocation, garbage collection strategies like ZGC or G1GC, and runtime performance flags. This is an essential utility for developers looking to eliminate IDE lag, manage large project memory footprints, and leverage modern JVM optimizations across different operating systems.
