An <em>agent</em> gets things done — it browses, runs code, calls APIs, queries databases, and iterates until the job is complete. The same LLM powers both, but the wrapper differs: an agent runs in a loop with tools, memory, and the ability to inspect its own work.</p> <p>This guide is the expanded version of that idea. It covers the four core capabilities (planning, memory, tool use, reflection), major framework families, multi-agent collaboration, evaluation, and the production concerns that determine whether an agent succeeds or fails.</p>
