145-java-refactoring-high-performance SKILL.md skillA
145-java-refactoring-high-performance from jabrena/plinth is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jabrena/plinth/145-java-refactoring-high-performance@v0.19.0Pins v0.19.0 in mdr.lock. Pin the fingerprint instead.

Use when you need to refactor Java code for high performance — including memory/allocation reduction, CPU hot-path optimization, and syntax/API/control-flow improvements. This should trigger for requests such as Review Java code for high performance; Optimize Java hot path; Reduce Java allocations; Improve Java latency/throughput. Part of Plinth Toolkit.
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
# Java rules for High Performance Identify and apply practical Java high-performance techniques using a measure-first approach, with emphasis on allocation reduction, data layout, concurrency discipline, and evidence-based validation. **What is covered in this Skill?** - Measure-first workflow for Java code optimization - JVM/runtime-aware coding guidance - Allocation reduction techniques with bad/good patterns - CPU hot-path simplification and loop-level efficiency patterns - Concurrency/backpressure and timeout/cancellation discipline - I/O, parsing, and serialization efficiency patterns - Persistence/query and caching strategy guidance - Java-centric decision workflow: keep/revert based on measured impact **Scope:** Practical optimization in application code and APIs. Apply only where profiling indicates real bottlenecks. ## Constraints Performance optimization must be evidence-driven and safe, focused on Java code changes that preserve correctness and maintainability. - **MEASURE-FIRST**: Establish baseline behavior and identify Java code hot paths before optimization - **NO PREMATURE OPTIMIZATION**: Only optimize code paths identified by profiling evidence …

How to install
mdr add jabrena/plinth/145-java-refactoring-high-performance@sha256:0e877aafee54425eThe line at the top of this page pins the label v0.19.0, 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.
