Production agentic systems need a context layer, not just LLM tool calls

A hands-on breakdown of production-grade agentic systems argues that LLM + tool use is only one layer.

The post says real systems need a context layer with shared memory, retrieval, and state; otherwise agents stay stateless, repeat themselves, and lose track of prior actions.
It also stresses observability and governance: an agent without monitoring is not truly autonomous, just unaccountable.
The attached diagram lays out an agentic engineering stack from developer interface, orchestration, tool use, and context, down to knowledge sources, execution/integrations, and monitoring/guardrails.
