A comprehensive reference covering 30 foundational concepts in agentic engineering, organized into six layers: Foundations (what agents are, execution models, state, patterns), Configuration (config files, workflow files, prompt caching, context rot), Capability (MCP, live doc retrieval, AI-native search, persistent memory, knowledge search), Orchestration (subagents, agent loops, orchestration tools, managed agents), Guardrails (sandboxing, permissions, hooks, prompt injection defense, structural linting, pre-commit gates, CI), and Observability (tracing, logging, replay, metrics). Each concept includes practical guidance on when to use it and what failure modes it prevents. The piece emphasizes learning durable ideas over chasing specific tools, and provides a recommended starting order for developers new to agentic workflows.
