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 |

Primitivas de simultaneidad de efecto de prueba que incluyen PubSub, Deferred, Latch, coordinación de fibra, SubscriptionRef y Stream. Utilice esta habilidad cuando pruebe efectos concurrentes, sistemas controlados por eventos o coordinación de fibras. Fuente: front-depiction/claude-setup.
