// summary

Ralph is an autonomous AI agent loop that repeatedly executes coding tasks using tools like Amp or Claude Code until all project requirements are met. Each iteration operates within a fresh context, maintaining project state through git history, progress logs, and a structured JSON task list. The system ensures continuous progress by breaking down large features into manageable user stories that are verified through automated quality checks.

// technical analysis

Ralph is an autonomous AI agent loop designed to execute coding tasks by repeatedly invoking AI tools like Amp or Claude Code until a project's requirements are fully met. Its core philosophy centers on maintaining a clean context for each iteration, preventing context window degradation by offloading persistent memory to git history, a progress log, and a structured JSON task list. This approach solves the problem of AI agents losing focus on large projects, ensuring that complex features are broken down into manageable, verifiable units that are systematically implemented and tested.

// key highlights

Implements an autonomous loop that spawns fresh AI instances for each task to ensure clean context and prevent performance degradation.

Utilizes a structured prd.json file to track user stories and their completion status, enabling the agent to prioritize and execute tasks sequentially.

Maintains persistent memory across iterations through git history, a progress.txt file, and AGENTS.md updates to capture project-specific learnings.

Supports modular integration with either Amp or Claude Code, allowing developers to choose their preferred AI coding tool.

Enforces a strict feedback loop by requiring quality checks, such as typechecks and tests, to pass before committing changes and marking tasks as complete.

Provides automated archiving of previous runs, ensuring that project history is preserved when starting new features.

// use cases

Automated execution of PRD-based user stories through iterative AI coding cycles.

Generation and conversion of product requirements into structured JSON formats for autonomous processing.

Continuous project documentation and learning persistence via automated updates to progress logs and AGENTS.md files.

// getting started

To begin, install either the Amp CLI or Claude Code and ensure 'jq' is available on your system. Copy the Ralph scripts and relevant prompt templates into your project directory, then generate a PRD and convert it into the required prd.json format. Finally, execute the loop using the ralph.sh script to start the autonomous development process.
