Effect

Ground every recommendation in the target project. Inspect repository instructions, the pinned effect version, installed package source, and local conventions before choosing APIs. Prefer project evidence over remembered signatures.

Choose the Relevant Guidance

Read only the references needed for the task, and combine them when concerns overlap:

• Schema, records, variants, brands, and typed errors: references/SCHEMA.md
• Services, layers, modules, scope ownership, and Effect.fn: references/SERVICES_LAYERS.md
• Configuration and providers: references/CONFIG.md
• Schedules, retry, repeat, polling, and pacing: references/SCHEDULING.md
• Cache, memoization, in-flight dedupe, and request batching: references/CACHING.md
• Streams, queues, PubSub, SubscriptionRef, and long-lived consumers: references/STREAMS.md
• HTTP clients, decoding, retries, and rate limits: references/HTTP_CLIENTS.md
• Effect-aware tests, TestClock, layers, and synchronization: references/TESTING.md

Model Data and Failures

• Use Schema.Struct(...) for application records.
