Does Ralph execute code automatically after setup?

No, the Ralph skill follows a strict safety rule: it only sets up the files, structure, and instructions. You must manually run the provided shell command to start the autonomous loop.

How does Ralph track implementation progress?

Ralph maintains a progress.txt file and a prd.json task list within your project's .claude/ralph folder to track which stories are completed and what remains to be done.

Can I use Ralph in any programming language?

Yes, Ralph is language-agnostic. It sets up a workflow for AI agents to follow, though it requires Bun to be installed to run the resulting execution script.

What happens during the interactive PRD mode?

Claude will brainstorm with you to define your feature's scope, goals, and acceptance criteria, then automatically format these into a structured JSON file that the AI loop can follow.

What is the benefit of using Ralph over standard chat?

Ralph provides a structured framework for long-running tasks, ensuring that the AI commits after every small success and maintains context across a complex, multi-step feature build.

Productivity & Workflow

Configures an autonomous AI coding environment to implement complex features through iterative task execution and PRD management.

Ralph is a specialized productivity skill designed to establish an autonomous AI coding pipeline within any project. It automates the transition from high-level Product Requirements Documents (PRD) to structured, actionable user stories, creating a dedicated environment where AI agents can implement code and commit changes one task at a time. While the skill handles the complex file structure setup and task extraction, it maintains a safe human-in-the-loop approach by preparing the environment and providing the final execution commands for the user to trigger manually, ensuring full oversight of the development process.
