rules4

A universal CLI utility to configure AI rules files (e.g., .roo/rules, CLAUDE.md, .cursor/rules) for any project, based on the latest industry best practices via live Perplexity research.

Features

• Supports any language or framework via --lang and --tags options
• Configures rules for tools like Cursor, Roo, Claude, and more
• Uses live Perplexity API for up-to-date best practices
• Dry-run mode to preview changes
• Prompts before overwriting existing files
• Simple one-command install (packaged for PyPI)
• Designed for future MCP integration

Quickstart

# Create and activate a virtual environment (required)
python3 -m venv .venv
source .venv/bin/activate

# Install dependencies
pip install -r requirements.txt

# Run the CLI (auto-detects project context if possible)
rules4 --lang python --tool cursor --tags langgraph,langchain,pytest

# Run tests
make test

Options

• --lang <language>: Programming language (e.g., python, javascript)
• --tool <tool>: Which rules file/tool to configure (e.g., cursor, roo, claude)
• --tags <tag1,tag2,...>: Comma-separated list of frameworks/libraries
• --dry-run: Show what would be changed without writing files
• --yes, -y: Overwrite files without prompting
• --project-path <path>: (Optional) Target project directory

Development

• Code files are kept short and simple
• Tests and >85% coverage are required
• All lint and security issues must be fixed
