CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Repository Overview

This is the Ralph for Claude Code repository - an autonomous AI development loop system that enables continuous development cycles with intelligent exit detection and rate limiting.

Core Architecture

The system consists of four main bash scripts that work together:

1. ralph_loop.sh - The main autonomous loop that executes Claude Code repeatedly
2. ralph_monitor.sh - Live monitoring dashboard for tracking loop status
3. setup.sh - Project initialization script for new Ralph projects
4. create_files.sh - Bootstrap script that creates the entire Ralph system

Key Commands

Installation

# Install Ralph globally (run once)
./install.sh

# Uninstall Ralph
./install.sh uninstall

Setting Up a New Project

# Create a new Ralph-managed project (run from anywhere)
ralph-setup my-project-name
cd my-project-name

Running the Ralph Loop

# Start with integrated tmux monitoring (recommended)
ralph --monitor

# Start without monitoring
ralph

# With custom parameters and monitoring
ralph --monitor --calls 50 --prompt my_custom_prompt.md

# Check current status
ralph --status

Monitoring

# Integrated tmux monitoring (recommended)
ralph --monitor

# Manual monitoring in separate terminal
ralph-monitor

# tmux session management
tmux list-sessions
tmux attach -t <session-name>

Ralph Loop Configuration

The loop is controlled by several key files and environment variables:

• PROMPT.md - Main prompt file that drives each loop iteration
• @fix_plan.md - Prioritized task list that Ralph follows
• @AGENT.md - Build and run instructions maintained by Ralph
• status.json - Real-time status tracking (JSON format)
• logs/ - Execution logs for each loop iteration

Rate Limiting

• Default: 100 API calls per hour (configurable via --calls flag)
• Automatic hourly reset with countdown display
• Call tracking persists across script restarts

Intelligent Exit Detection

The loop automatically exits when it detects project completion through:

• Multiple consecutive "done" signals from Claude Code
• Too many test-only loops indicating feature completeness
• All items in @fix_plan.md marked as completed
• Strong completion indicators in responses

Project Structure for Ralph-Managed Projects

Each project created with ./setup.sh follows this structure:

project-name/
├── PROMPT.md          # Main development instructions
├── @fix_plan.md       # Prioritized TODO list
├── @AGENT.md          # Build/run instructions
├── specs/             # Project specifications
├── src/               # Source code
├── examples/          # Usage examples
├── logs/              # Loop execution logs
└── docs/generated/    # Auto-generated documentation

Template System

Templates in templates/ provide starting points for new projects:

• PROMPT.md - Instructions for Ralph's autonomous behavior
• fix_plan.md - Initial task structure
• AGENT.md - Build system template

File Naming Conventions

• Files prefixed with @ (e.g., @fix_plan.md) are Ralph-specific control files
• Hidden files (e.g., .call_count, .exit_signals) track loop state
• logs/ contains timestamped execution logs
• docs/generated/ for Ralph-created documentation

Global Installation

Ralph installs to:

• Commands: ~/.local/bin/ (ralph, ralph-monitor, ralph-setup)
• Templates: ~/.ralph/templates/
• Scripts: ~/.ralph/ (ralph_loop.sh, ralph_monitor.sh, setup.sh)

Integration Points

Ralph integrates with:

• Claude Code CLI: Uses npx @anthropic/claude-code as the execution engine
• tmux: Terminal multiplexer for integrated monitoring sessions
• Git: Expects projects to be git repositories
• jq: For JSON processing of status and exit signals
• Standard Unix tools: bash, grep, date, etc.

Exit Conditions and Thresholds

• MAX_CONSECUTIVE_TEST_LOOPS=3 - Exit if too many test-only iterations
• MAX_CONSECUTIVE_DONE_SIGNALS=2 - Exit on repeated completion signals
• TEST_PERCENTAGE_THRESHOLD=30% - Flag if testing dominates recent loops
• Completion detection via @fix_plan.md checklist items
