4 Types of Loops You Can Create in Claude Code

Summary

The article introduces the concept of loops within Claude Code interactions, explaining that these cycles fundamentally involve Claude reviewing the current state of a task, deciding on the next action, performing it, and then evaluating the result. It specifically details the "Turn-Based Loop" as the standard interaction model. In this loop, a user prompts Claude, Claude acts and returns a result, and then waits for the user's subsequent review and prompt before initiating another turn. Claude can execute multiple actions, such as reading files, editing code, or running commands, within a single turn, but it will not proceed to a new turn without explicit user input. The article notes there are four types of loops in total.

Key takeaway

For AI Engineers designing interactive Claude Code workflows, understanding the turn-based loop is crucial for managing interaction flow. You should explicitly structure your prompts to define clear turns, ensuring Claude completes its actions and awaits your review before proceeding. This approach allows you to maintain precise control over the iterative development process, preventing unintended autonomous cycles and enabling effective debugging.

Key insights

Claude Code interactions fundamentally involve iterative cycles of state review, decision, action, and evaluation.

Principles

• Claude waits for user input.
• Actions precede evaluation.

Method

Claude's core loop involves reviewing the current task state, deciding the next action, performing it, and then evaluating the result before proceeding.

In practice

• Use turn-based loops for direct control.
• Structure prompts for clear turns.
