agent-communication-hub

Reliable inter-agent messaging with offline queueing is configured by registering agents in a communication hub with SQLite-backed persistence. This stores messages durably and guarantees delivery acknowledgement even when agents are temporarily offline.

Event pub/sub with payload filtering is a messaging pattern where agents subscribe to specific event types and receive filtered payloads. This skill supports it with replay capabilities to recover missed events and maintain accurate worker state in distributed workflows.

Agent presence and session history are tracked by registering agents in a communication hub that maintains online/offline states. The system logs session histories in SQLite, providing an auditable record of agent interactions and presence transitions.

Yes, SQLite persistence works for broadcasting messages to offline agents by queuing the messages in an offline queue. When the offline agent reconnects and comes online, the queued broadcast messages are delivered and acknowledged.

Yes, you can replay event subscriptions to audit agent communication history because the messaging backbone uses SQLite-backed audit logs. This allows you to recover and replay past events with their filtered payloads for auditing distributed workflows.

Using SQLite for agent message persistence provides durable local storage but may face limitations with highly concurrent writes across a large distributed workflow. It is designed for reliable delivery and audit logs rather than high-throughput distributed database scaling.
