Design and diagnose ForkJoinPool workloads using work-stealing topology, task graphs, granularity, common-pool interference, managed blocking, compensation limits and approximate pool telemetry. Use when parallel computation underutilizes CPUs, parallel streams interfere, joins stall, blocking collapses effective parallelism, or copied thresholds and pool constants are being treated as universal policy. Includes Java 25 API changes with version labels.
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
# ForkJoinPool and Work Stealing ## Purpose Use `ForkJoinPool` for decomposable task graphs where workers create enough independent work to steal. Its advantage is not “more threads”; it is distributed scheduling queues plus join-aware assistance for nested computations. Correctness still comes from task ownership and Java Memory Model synchronization, and throughput still depends on useful work per task and the real bottleneck. This skill owns pool/task-graph behavior. General concurrency choice belongs to `java-concurrency`, pool capacity math to `thread-sizing-and-virtual-threads`, and benchmark validity to `jmh-microbenchmarks`. ## Decision workflow Use Java 17 as the portable baseline for the task/blocker snippets; inspect the target toolchain, runtime build and deployment limits before applying release-specific APIs. Virtual-thread executors require Java 21+; `close()` and `setParallelism` require Java 19+. Do not upgrade the project merely to apply a recommendation. API claims below are checked against Java 25 unless otherwise labelled. Reuse the requested outcome, existing profiles/configuration and accepted resource/recovery limits. …

How to install
mdr add robsonkades/agent-skills/forkjoinpool-and-work-stealing@sha256:0f7e23e796d68cf2The line at the top of this page pins the label git:20260927.9ecadfd, 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.
