A Ralph Wiggum Loop implementation that works™

📚 Full docs: [ralphloop.sh](https://ralphloop.sh)

Ralph is a long-running AI agent loop. Ralph automates software development tasks by iteratively working through a task list until completion. This allows for long running agent loops, effectively enabling AI to code for days at a time.

This is an implementation that actually works, containing a hackable script so you can configure it to your env and favorite agentic AI CLI. It's set up by default to use Claude Code in Docker Sandboxes, and supports [multiple Docker Sandboxes agents](#running-with-a-different-agentic-cli).
