## What it is
Rulesync is a Node.js CLI tool that generates configuration files for various AI coding assistants (Claude Code, Cursor, Copilot, Gemini CLI, etc.) from unified AI rule files. It supports rules, commands, MCP configs, ignore files, subagents, and skills, with import/export and direct conversion between tools.

## Use cases
- sync AI assistant rules across multiple coding tools from one source
- convert cursorrules to CLAUDE.md
- import existing copilot instructions into a unified format
- generate MCP configuration files for different AI agents
- onboard team members with consistent AI coding conventions
- manage AI agent skills and subagents across tools

## When to choose
- your team uses multiple AI coding assistants and you want one set of rules
- you need to migrate or convert configs between AI tools
- you want auditable, committable generated config files

## When to avoid
- you use only one AI coding tool and never change it
- you need a GUI-based configuration manager
