Command Line Interface

You can also use command line flags to skip the interactive prompts:

# Generate rules for a specific AI app and topic
npx agent-rules --app cursor --topics secure-code

# Generate rules for multiple topics
npx agent-rules --app github-copilot --topics secure-code --topics testing

# Include MCP (Model Context Protocol) configuration
npx agent-rules --app github-copilot --topics testing --mcp

# Include custom commands (prompts)
npx agent-rules --app github-copilot --topics secure-code --commands

# Combine multiple features
npx agent-rules --app github-copilot --topics secure-code --mcp --commands

# Use short flags
npx agent-rules -a claude-code -t security-vulnerabilities -m -c

# Show help
npx agent-rules --help

# Show version
npx agent-rules --version

Features

📋 Instructions & Rules

Scaffold AI-specific coding instructions and best practices rules into your project:

• Security-focused coding practices
• Vulnerability detection and remediation
• Testing strategies and guidelines

🔌 MCP (Model Context Protocol) Configuration

Automatically configure MCP servers for enhanced agentic coding capabilities:

• GitHub Copilot: Configures .vscode/mcp.json
• Gemini CLI: Configures .gemini/settings.json
• Non-destructive merging with existing configurations

Learn more in the MCP Feature Documentation.

⚡ Custom Commands & Prompts

Scaffold reusable commands and prompts for your AI coding assistant:

• GitHub Copilot: Deploys to .github/prompts/ as prompt files
• Pre-built commands for common workflows (e.g., implementing GitHub issues)
• Easily extensible with your own custom commands

Learn more in the Commands Feature Documentation.

Rules

Current category of rules available:

• Secure coding practices, based on Liran Tal's Node.js Secure Coding
