If you’ve been building AI agents or working with Large Language Models recently, you’ve likely hit the integration wall. Historically, connecting an LLM like Claude or GPT-4 to external environments—such as querying a production database, checking system logs, or interacting with a local file system—required building ad-hoc, brittle integration layers. Every single AI framework required bespoke tool definitions, custom JSON-parsing loops, and hardcoded prompt engineering just to hand
