Simon Willison Publishes Agentic Engineering Patterns Guide: Subagents, Context Architecture, and How Coding Agents Work
Willison published multiple new chapters of his Agentic Engineering Patterns guide covering subagent architecture (delegating subtasks to overcome context limits), the internal mechanics of coding agents (tool loops, file I/O, LLM calls), and the formal definition of agentic engineering. The guide is structured as a practitioner reference with specific attention to context window management, when spawning subagents is architecturally correct, and distinguishing agentic patterns from standard LLM usage.
