A practical arXiv guide (December 2025, widely circulated now) lays out nine engineering principles for shipping agentic AI in production: tool-first design over MCP, pure-function invocation, single-tool and single-responsibility agents, externalized prompt management, and containerized deployment. The core theme: treat agents like microservices — each one should be focused, testable, and independently deployable.
