executors-and-task-lifecycle from robsonkades/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Engineering the full lifecycle of tasks accepted by Java executors: ownership, admission, queue/grow behavior, execution context, result/failure observation, rejection, cancellation, scheduled/periodic semantics, context cleanup, shutdown/drain and recovery. Covers ThreadPoolExecutor, scheduled pools and thread-per-task/virtual-thread executors without treating factory defaults as capacity policy. Use when work disappears, queues grow, rejection or deploy loses work, or a virtual-thread…
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
# Executors and task lifecycle ## Purpose Make each task transition—created, admitted, queued, started, completed/failed/cancelled, observed, and drained—owned and observable. An executor schedules Java work; it is not automatically a durable queue, downstream limiter, supervisor, retry engine, context carrier or graceful-shutdown policy. Reuse the supplied executor configuration, task contract and existing test/operational evidence. Keep an adequate design, including a factory pool whose producer bounds are established. Execution model and worker-count selection belong to `thread-sizing-and-virtual-threads`; this skill owns what happens to accepted and rejected work across that executor's lifetime. Inspect compiler/runtime and executor implementation before applying examples. The references use standard platform-executor APIs available on Java 17; `ExecutorService.close` is available since 19, and virtual-thread-per-task executors since 21. Preserve the target; do not upgrade to fit a factory method. With missing workload or durability evidence, record a conditional design and the smallest saturation/restart experiment needed before selecting capacity or loss policy. …

How to install
mdr add robsonkades/agent-skills/executors-and-task-lifecycle@sha256:fee7612f2b13f89eThe line at the top of this page pins the label git:20261028.082d2f4, 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.
