Jido Messaging

jido_messaging is the upstream Hex package name.

Start Here

Use this skill when the task is about moving Jido signals across external transports such as queues, brokers, or pub/sub systems.

Good triggers:

• "Bridge Jido signals onto a message bus."
• "Design a messaging adapter for this Jido app."
• "Review delivery semantics and retries for external dispatch."
• "Figure out whether this logic belongs in jido_messaging or jido_signal."

Public docs for this package are thin. Require a concrete target transport or integration before getting specific, and keep any unsupported transport behavior explicit as an assumption.

Primary Workflows

Design an adapter boundary

• Start from the signal contract, then map it onto transport topics, subjects, or queues.
• Keep serialization, headers, and correlation ids explicit.
• Separate transport delivery from core signal creation and validation.

Define delivery semantics

• Decide whether the workflow needs at-most-once, at-least-once, ordering, or replay guarantees.
• Keep retry and dead-letter behavior in the adapter boundary, not in the signal schema.
• Surface ack or failure information in a way the application can observe.

Review package boundaries

• Keep signal definitions in jido-signal.
• Keep transport adapters and delivery concerns in jido-messaging.
• Keep domain-specific message handling in the application layer.

Build Checklist

• Identify the transport first.
• Define serialization and routing keys before coding.
• Make correlation and retry behavior observable.
• Add tests for invalid payloads, redelivery, and missing consumers.

Boundaries

• Do not invent support for a broker or transport that the docs do not mention.
• Do not collapse signal schema and transport wiring into one module.
• Do not hide delivery guarantees or failure modes from callers.
