What is a Ralph Loop?

A Ralph Loop is an autonomous execution cycle where Claude iteratively performs tasks from a plan, runs mandatory validations, and logs progress until the entire goal is achieved.

What are the mandatory validation steps?

Every iteration must pass type-checking, linting, unit tests, and build checks. The loop will not signal completion until every validation returns a success code.

How do I stop an active Ralph Loop?

You can manually stop the process by using the /prp-ralph-cancel command, which removes the state file and halts the autonomous execution cycle.

How does Ralph maintain context between iterations?

It uses a state file located at .claude/prp-ralph.state.md which stores the current iteration count, progress logs, discovered codebase patterns, and the path to the active plan.

生产力与工作流

Executes and manages autonomous coding loops with integrated validation, state tracking, and iterative progress logging.

关于

The PRP Ralph Loop skill enables Claude to function as an autonomous agent by following a structured iteration protocol designed for complex engineering tasks. It manages state via a dedicated local file, ensuring that multi-step development plans are executed systematically with mandatory validation checks—including type-checking, linting, and testing—at every stage. This skill is particularly useful for long-running tasks where maintaining context across iterations and ensuring production-grade code quality through autonomous refinement are essential.
