Core Features

Autonomous AI Agent Loop

Ralph runs AI coding tools repeatedly until all PRD items are complete, with each iteration starting with a fresh context.

Source: README
Memory Persistence

Memory persists via git history, `progress.txt`, and `prd.json`, allowing the loop to remember and build upon previous iterations.

Source: README
Skill Integration

Ralph integrates with AI coding tools like Amp and Claude Code, providing skills for generating PRDs and converting them to JSON format.

Source: README
Branch and Story Management

Ralph creates feature branches, picks the highest priority story, implements it, and updates the PRD status accordingly.

Source: README

Architecture

The architecture of Ralph involves a bash loop that spawns AI instances, integrates with AI coding tools for task execution, and manages memory persistence through various files and git history. It uses a modular approach with skills for PRD generation and conversion, and leverages feedback loops for continuous improvement.
