OpenClaw Architecture

OpenClaw puts channels, sessions, and devices behind one Gateway daemon. The agent does not speak Telegram or WhatsApp; it speaks the Gateway’s typed WebSocket. Channel plugins are ingress, not a second runtime.

One Gateway maps to one trust boundary. Extra channels, agents, and nodes stack in the same process. Split the Gateway when operators do not share trust, not when a second chat app appears.

AI Agent Architecture Patterns: Model + Harness + Memory

Building effective agents splits agentic systems in two: workflows run LLMs and tools on predetermined code paths; agents let the model choose the next tool. Production systems in 2026 are still that split, plus a harness and memory the model can retrieve. If the steps can be written down, pick a graph. If they cannot, pick a loop. Multi-agent is not the default.
