Claude Code's agent loops provide a tangible upgrade in autonomy and structured reasoning. Remember that the terminal must be left on continuously and sessions are limited (e.g., 3-day max).

Still, agent loops significantly enhance efficiency for scoped coding tasks and allow Claude to autonomously cycle through context gathering, tool actions like code editing or testing, and result verification. New capabilities include seamless tool integration, user interruptibility, model switching (e.g., Sonnet for routine work, Opus for complex), and self-correction.
