How do I start an autonomous development session?

You can start a session by providing a specification file and using the command '/marathon-ralph:run path/to/spec.md' or by asking Claude to 'marathon this spec'.

Does this skill require third-party tools?

Yes, Marathon Ralph requires the Linear MCP to be configured so it can manage project issues, track progress, and organize the development workflow.

What is Marathon Ralph?

Marathon Ralph is a specialized skill for Claude Code that enables autonomous, long-running development sessions to build software directly from specification files.

Can I stop and resume a marathon later?

Yes. Marathon Ralph saves its progress in a state file within your project directory, allowing you to cancel a session and resume exactly where it left off later.

How does it ensure code quality?

The skill follows a strict loop for every issue: it plans the change, implements the code, runs linting and type checks, and writes unit and E2E tests to verify the implementation before moving on.

Automates long-running software development cycles from specification files through autonomous coding and testing loops.

소개

Marathon Ralph is an advanced autonomous development skill for Claude Code designed to transform project specifications into fully implemented, production-ready applications. By integrating with the Linear MCP, it systematically breaks down specifications into tracked issues, executes a continuous development cycle—including planning, coding, and comprehensive testing—and manages project state across multiple sessions. This skill is ideal for developers looking to delegate large-scale feature implementation or end-to-end application builds to Claude while maintaining professional workflow standards, rigorous verification, and clear progress tracking.
