Patterns for Agentic Tools: Your agents are only as good as your tools.

The Moment Every few years, a new pattern language emerges that changes how we build software. In 1994, the Gang of Four gave us Design Patterns. In 2003, Hohpe and Woolf gave us Enterprise Integration Patterns. Since then: Microservices Patterns, Cloud Patterns, and now Agent Patterns. But there's a gap. Agents can chat and reason on their own - but they can't ‘act’ without tools. Standards like MCP have unlocked how agents discover and call tools. The protocol layer is solved. What's missin

The Birth of Machine Experience Engineering

LLMs acting on behalf of humans and interacting with real-world systems isn't theoretical anymore - with the advent of function calling, it is now a reality. And with Arcade, function calling becomes a superpower that connects LLMs to authorized APIs, user services, and complex systems. With this shift, we're seeing the emergence of a new software practice: Machine Experience Engineering (MX Engineering). The Current Reality For AI models to handle our emails, schedule appointments, and manag
