Architecting Agentic Systems Book
Engineering Dependable AI Agents
A technical reference for senior engineers and architects: a formal pattern language for agentic systems, and the architectural discipline — bounded autonomy, governance as architecture, memory and state, the ingestion pipeline, control and coordination, the skills layer, failure-mode taxonomy, testing and trace discipline, and the harness — that turns patterns into reliable production systems. The full text is free to read online.
