name: effect-facet-unstable-cluster-messagestorage description: Guidance for facet effect/unstable/cluster/MessageStorage focused on APIs like make, Encoded, and layerNoop. Load after effect-skill-router when this facet is the primary owner.

Effect Facet unstable/cluster/MessageStorage

Owned scope

• Owns only effect/unstable/cluster/MessageStorage.
• Parent module: effect/unstable/cluster.
• Source anchor: packages/effect/src/unstable/cluster/MessageStorage.ts.

What it is for

• Module-specific APIs and usage patterns for Effect programs.

API quick reference

• make
• Encoded
• layerNoop
• layerMemory
• makeEncoded
• EncodedRepliesOptions
• EncodedUnprocessedOptions
• noop
• Success
• Duplicate
• SaveResult
• Constructor
• MemoryEntry
• MemoryDriver
• DuplicateEncoded
• MessageStorage
• SaveResultEncoded
• Full API list: references/api-reference.md

How to use it

• Start with constructor-style APIs to build values/services before composing operations.
• Use schema/codec APIs to validate inputs at boundaries before business logic.
• Assume unstable APIs can evolve quickly; isolate usage behind thin local adapters.

Starter example

import { MessageStorage } from "effect/unstable/cluster/MessageStorage";

const value = MessageStorage.make();
const next = MessageStorage.Encoded(value);

Common pitfalls

• Unstable module contracts may change; avoid coupling core app logic directly to experimental details.
• Prefer explicit, typed combinators over ad-hoc casting or unchecked assumptions.

Not covered here

• Sibling facets under the same parent are out of scope:
  • effect-facet-unstable-cluster-clustercron (effect/unstable/cluster/ClusterCron)
  • effect-facet-unstable-cluster-clustererror (effect/unstable/cluster/ClusterError)
  • effect-facet-unstable-cluster-clustermetrics (effect/unstable/cluster/ClusterMetrics)
  • effect-facet-unstable-cluster-clusterschema (effect/unstable/cluster/ClusterSchema)
  • effect-facet-unstable-cluster-clusterworkflowengine (effect/unstable/cluster/ClusterWorkflowEngine)
  • effect-facet-unstable-cluster-core (effect/unstable/cluster#core)
  • effect-facet-unstable-cluster-deliverat (effect/unstable/cluster/DeliverAt)
  • effect-facet-unstable-cluster-entity (effect/unstable/cluster/Entity)
  • effect-facet-unstable-cluster-entityaddress (effect/unstable/cluster/EntityAddress)
  • effect-facet-unstable-cluster-entityid (effect/unstable/cluster/EntityId)
  • effect-facet-unstable-cluster-entityproxy (effect/unstable/cluster/EntityProxy)
  • effect-facet-unstable-cluster-entityproxyserver (effect/unstable/cluster/EntityProxyServer)
  • effect-facet-unstable-cluster-entityresource (effect/unstable/cluster/EntityResource)
  • effect-facet-unstable-cluster-entitytype (effect/unstable/cluster/EntityType)
  • plus 29 additional sibling facets.
• Parent module ownership belongs to effect-module-unstable-cluster.

Escalate to

• effect-module-unstable-cluster for parent module-wide workflows.
• effect-skill-router for cross-module routing and ownership checks.
