## What it is
Ralph is an autonomous AI agent loop that repeatedly runs AI coding tools like Amp or Claude Code until all items in a product requirements document (PRD) are complete. Each iteration starts with a fresh context, with memory persisted through git history, progress.txt, and prd.json.

## Use cases
- run an AI coding agent autonomously until my PRD is done
- automate implementing user stories with Claude Code
- loop an AI coding tool with fresh context each iteration
- generate PRDs and convert them to JSON for autonomous execution
- let an AI agent work through a backlog of features unattended
- orchestrate Amp or Claude Code in a repeatable loop

## When to choose
- you already use Amp or Claude Code and want autonomous multi-iteration execution
- you work PRD-driven and want tasks tracked in prd.json with git-based memory
- you want a simple shell-based loop rather than a heavy agent framework

## When to avoid
- you need a general-purpose agent framework with custom tooling and APIs
- you don't use Amp or Claude Code as your coding assistant
- you want fine-grained human review at every step rather than autonomous loops
