SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables autonomous development sessions that convert specifications into working software, managing progress across sessions and ensuring test coverage.

Core Features & Use Cases

  • Spec-to-Project: Turn a spec file into a Linear-based project with issues.
  • Autonomous Loop: Continuously prioritize, implement, test, and commit features.
  • Progress Tracking: Persist state across sessions and expose stop/cancel controls.

Quick Start

Start a marathon with a spec file: /marathon-ralph:run path/to/spec.md and monitor progress with /marathon-ralph:status.
