Agentic coding Session 1 — The Agentic Mental Model

The Agentic Mental Model: what "agentic" means and the loop, the context window as the governing constraint, explore→plan→implement→commit, verification, and precise prompting.Most engineers meet AI coding tools as a smarter autocomplete. Claude Code is something else: an agent that explores, plans, and writes code on its own while you direct and review. This opening episode rewires how you think about the tool. We unpack what "agentic" actually means, why the context window is the one constraint that explains every best practice, the explore-plan-implement-commit workflow, and the discipline of verification — giving the agent a check it can run so it self-corrects. The foundation for everything that follows, and for any interview that asks how you think with an AI agent.
