Rulesync

Rulesync generates and synchronizes AI rule configuration files across 20+ coding tools (Claude Code, Cursor, Copilot, Windsurf, Cline, Gemini CLI, and more) from a single set of unified rule files in 

.rulesync/
.

Quick Start

# Install
npm install -g rulesync

# New project: initialize config, rules, and directory structure
rulesync init

# Import existing AI tool configs into unified format
rulesync import --targets claudecode    # From CLAUDE.md
rulesync import --targets cursor        # From .cursorrules
rulesync import --targets copilot       # From .github/copilot-instructions.md

# Generate tool-specific configs from unified rules
rulesync generate --targets "*" --features "*"

Core Workflow

  1. Init - 
    rulesync init
    creates 
    rulesync.jsonc
    config and 
    .rulesync/
    directory with sample rules
  2. Write rules - Add shared AI rules in 
    .rulesync/rules/
    , MCP configs in 
    .rulesync/mcp/
    , commands in 
    .rulesync/commands/
  3. Generate - 
    rulesync generate
    produces tool-specific files (CLAUDE.md, .cursorrules, .github/copilot-instructions.md, etc.)
  4. Verify - 
    rulesync generate --dry-run
    previews changes; 
    --check
    validates files are up to date (useful in CI)
