nexo-core

Agent runtime: event bus, sessions, plugin trait, heartbeat, A2A delegation.

This crate is part of Nexo — a multi-agent Rust framework with a NATS event bus, pluggable LLM providers (MiniMax, Anthropic, OpenAI-compat, Gemini, DeepSeek), per-agent credentials, MCP support, and channel plugins for WhatsApp, Telegram, Email, and Browser (CDP).

• Documentation: https://lordmacu.github.io/nexo-rs/

What this crate does

• Agent trait + dispatcher: turns inbound events into LLM turns, tool calls, and channel responses.
• Plugin trait: contract every channel plugin implements (on_event, on_send, lifecycle hooks).
• SessionManager: per-conversation state, transcript persistence, FTS-indexed search, redaction.
• Heartbeat runtime for proactive turns (reminders, periodic checks, external-state polling).
• Agent-to-agent (A2A) routing: agent.route.{target_id} topic + correlation_id for request/response between agents.
• Per-binding capability overrides — restrict skills, tools, or LLM models per agent×channel pair.
