Optimize memory usage, consistency, and performance by migrating standard Java/Kotlin classes to IntelliJ's specialized com.intellij.util implementations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill: API Migration to use com.intellij.util.* classes and methods You are tasked with optimizing memory usage, consistency, and performance by migrating standard Java/Kotlin classes to IntelliJ's specialized `com.intellij.util` implementations. ## Objective Go read https://javadoc.jetbrains.net/teamcity/openapi/current/com/intellij/util/package-summary.html, and then optimize memory usage, consistency, and performance by migrating standard Java/Kotlin classes to IntelliJ's specialized `com.intellij.util` implementations. ## Candidates for Migration - `ArrayList` -> `SmartList` (for potentially empty/small lists) - `HashMap` / `ConcurrentHashMap` -> `ContainerUtil` maps - `String` manipulation -> `StringUtil` (e.g., `isEmpty`, `join`, `notNullize`) - `Path` / `File` string manipulation -> `PathUtil` - `javax.swing.Timer` -> `Alarm` (for UI-related callbacks/debouncing) - Null checks -> `ObjectUtils` (e.g., `doIfNotNull`, `coalesce`) - Array resizing/merging -> `ArrayUtil` ## Workflow Instructions ### 1. Baseline - Run `./gradlew testClasses`, `./gradlew test`, and `./gradlew verifyPlugin` to ensure project is in a good state. ### 2. Select Target …

How to install
mdr add flutter/flutter-intellij/migrate-intellij-util@sha256:ef7252b49cdbed99The line at the top of this page pins the label git:20260710.61b665d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
