You'll understand what the Claude Code agent loop is, how it drives autonomous multi-step task execution, and why it's the core engine behind Claude Code's agentic behavior.
You'll trace a complete agent loop cycle — from receiving a prompt to returning a final response — and identify each phase Claude Code moves through during execution.
You'll learn how Claude Code invokes tools (like file read/write and bash) within the loop, and understand how tool results feed back into the next iteration.
You'll understand the conditions that cause the agent loop to continue iterating versus stop, including task completion signals and max-turn limits.
You'll learn how to interrupt a running agent loop, when Claude Code will pause to ask for human input, and how to resume or abort execution safely.
You'll configure agent loop settings through the Claude Code Agent SDK — such as system prompts, allowed tools, and turn limits — to shape how the loop runs for your use case.
