SKILL.md

This skill provides patterns for testing Effect's concurrency primitives: fibers, latches, deferreds, PubSub, SubscriptionRef, and streams.

CRITICAL: Choose the correct coordination primitive based on what you need to synchronize.

| Simple fiber yield | Effect.yieldNow | | Forked PubSub subscriber ready | yieldNow after fork, yieldNow after each publish | | Wait for subscriber ready | Deferred.make() + Deferred.await | | Wait for stream element | Effect.makeLatch() + Stream.tap(() => latch.open) | | Time-dependent behavior | TestClock.adjust |

PubSub、Deferred、Latch、ファイバー調整、SubscriptionRef、Stream などのテスト効果の同時実行プリミティブ。このスキルは、同時効果、イベント駆動型システム、またはファイバー調整をテストするときに使用します。 ソース: front-depiction/claude-setup。
