allocation-profiling SKILL.md skillA
allocation-profiling from robsonkades/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add robsonkades/agent-skills/allocation-profiling@git:20261016.c769bd8Pins git:20261016.c769bd8 in mdr.lock. Pin the fingerprint instead.

Attribute Java heap allocation to code and validate reductions in bytes per operation. Use when allocation or GC frequency regresses, JFR allocation events are empty or disagree with counters, large buffers trigger G1 humongous collections or ZGC stalls, or pooling, TLAB tuning, or assumed JIT elimination is proposed without measurements. Covers sampling semantics and allocation-specific triage; general capture selection belongs to jfr-and-async-profiler, retention diagnosis to…
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
# Allocation Profiling Find which code produces heap bytes, decide whether those bytes are avoidable, and test whether reducing them improves the reported problem. Allocation is neither retained heap nor GC cost. A large allocation site is a candidate, not automatically the cause of latency. The reference baseline is OpenJDK 25 GA and async-profiler 4.1, not a minimum target version. Before version-sensitive advice, inspect Maven/Gradle release and toolchain settings, resolved logging/profiler dependencies, CI/runtime images and actual JVM flags. Keep the project's Java and dependency versions; using this skill does not authorize upgrades or enabling preview/experimental features. HotSpot-specific events and flags are not portable Java guarantees. ## Workflow 1. **Define the comparison.** Record the JDK build, collector, heap and relevant flags, profiler version, workload/payload mix, concurrency, warm-up state, affected time window, and target metric. Reuse the existing handoff, project evidence and artifacts before asking for missing facts that change the tool or decision. With source alone, provide a hypothesis …

How to install
mdr add robsonkades/agent-skills/allocation-profiling@sha256:511527bcf55fae14The line at the top of this page pins the label git:20261016.c769bd8, 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.
