Chip Huyen's agent writeup is useful as a systems map rather than a hype post. It treats agents as planning, tool use, memory, feedback, and environment design, which is the level where most production mistakes actually happen.
I would pair this with Anthropic's piece when deciding whether a workflow should stay deterministic or earn the complexity of agentic control.
