The AI Enablement Stack is a comprehensive taxonomy that maps out the essential tools and platforms needed for AI agents to operate effectively. It comprises five interconnected layers: Infrastructure, Intelligence, Engineering, Observability and Governance, and Agent Consumer Layer. The stack provides critical capabilities that deliver value through consumer-facing AI agents, empowering them to work beyond file manipulation and utilize dynamic workspaces for testing and refinement. The AI Enablement Stack is designed to provide a five-layer structure that builds from foundational infrastructure up to the consumer-facing AI agents that deliver real-world value, with each layer providing critical capabilities that unlock an AI agent's full operational potential.
