messaging

AI Agent Addressed agent-to-agent messaging for PraisonAI Agents. Provides a first-class, addressed messaging primitive: send a message to a named recipient agent and receive/subscribe to your inbox. This complements the existing mechanisms rather than replacing them:

bus — type-filtered, in-process pub/sub (no recipient addressing).
kanban comments — shared task board (pull-based, task-scoped).
handoff — synchronous parent -> child delegation.

Protocol-first (AGENTS.md §3.2): the core SDK ships the AgentMailboxProtocol contract plus a light in-process default (:class:InProcessMailbox). The wrapper (praisonai) can add a heavy Redis-backed implementation for cross-process / cross-host fleets under an agent: namespace. Zero overhead: nothing is instantiated unless a mailbox is explicitly created. Usage:

from praisonaiagents.messaging import InProcessMailbox

mailbox = InProcessMailbox()
mailbox.send("writer", {"findings": data}, sender="researcher")
msgs = mailbox.receive("writer")
