Installation

npm install -g rulesync
# or
brew install rulesync

Single Binary

curl -fsSL https://github.com/dyoshikawa/rulesync/releases/latest/download/install.sh | bash

See Installation docs for manual install and platform-specific instructions.

Getting Started

# Create necessary directories, sample rule files, and configuration file
rulesync init

# Install official skills (recommended)
rulesync fetch dyoshikawa/rulesync --features skills

# Generate unified configurations with all features
rulesync generate --targets "*" --features "*"

If you already have AI tool configurations:

# Import existing files (to .rulesync/**/*)
rulesync import --targets claudecode    # From CLAUDE.md
rulesync import --targets cursor        # From .cursorrules
rulesync import --targets copilot       # From .github/copilot-instructions.md

Want to convert configuration from one AI tool to another directly, without adopting the .rulesync/ source-of-truth workflow?

# Convert Cursor rules to Copilot and Claude Code in one shot (no .rulesync/ files written)
rulesync convert --from cursor --to copilot,claudecode

See Quick Start guide for more details.
