How to Set Up and Use Rulesync
Rulesync is a CLI utility that provides a single source of truth for AI coding agent configurations, letting you write rules, MCP server definitions, commands, and skills once and then generate the correct config files for 25+ AI tools including Claude Code, Cursor, GitHub Copilot, Gemini CLI, and Cline. It supports importing existing configurations from one tool and converting them to another format, making it easy to maintain consistent coding standards and agent behavior across every AI assistant your team uses. Teams adopt it to eliminate the manual effort of keeping tool-specific config files synchronized as AI tooling evolves.
Prerequisites
- Node.js 16 or later (for npx usage)
- npm or Homebrew (for alternative installation methods)
- At least one AI coding tool installed: Claude Code, Cursor, GitHub Copilot, Cline, or similar
- An MCP-compatible client for accessing the Rulesync MCP server
Install Rulesync
Install Rulesync globally via npm, Homebrew, or the one-line install script. The npm method is the most straightforward for most developers.
npm install -g rulesync
# OR via Homebrew:
brew install rulesync
# OR via install script:
curl -fsSL https://github.com/dyoshikawa/rulesync/releases/latest/download/install.sh | bashInitialize a Rulesync project
Run 'rulesync init' in your project root to create the .rulesync/ directory structure with starter template files for rules, MCP config, commands, and skills.
rulesync initEdit your source rules
Open the files in the .rulesync/ directory and define your project rules, MCP server configurations, and agent skills in the Rulesync format. These become the single source of truth for all generated tool configs.
Generate configurations for all tools
Run the generate command to output config files for every supported AI coding tool. Use --targets to limit output to specific tools and --features to control which feature types are generated.
rulesync generate --targets "*" --features "*"Import an existing tool configuration
If you already have a configuration for one tool and want to bring it into Rulesync, use the import command to convert it to the Rulesync format.
rulesync import --targets claudecodeConvert between tool formats
Use the convert command to translate configurations directly from one AI tool's format to another without going through the Rulesync intermediate format.
rulesync convert --from cursor --to copilot,claudecodeRulesync Examples

Example prompts for using Rulesync through an MCP client to manage AI tool configurations.
- "Generate Claude Code and Cursor configurations from my .rulesync directory"
- "Import my existing Cursor rules into Rulesync format"
- "Convert my Claude Code configuration to GitHub Copilot format"
- "Fetch the official Rulesync skill collection and add it to my project"
- "List all the AI tools Rulesync can generate configurations for"Troubleshooting Rulesync
rulesync: command not found after npm install
Ensure the global npm bin directory is in your PATH. Run 'npm bin -g' to find the directory and add it to your shell profile (e.g., export PATH="$(npm bin -g):$PATH" in ~/.zshrc). Alternatively, use 'npx -y rulesync' to run without a global install.
Generated config files are empty or missing expected entries
Check that your .rulesync/ directory contains properly formatted source files after running 'rulesync init'. The generate command only outputs entries for features that exist in the source files — if rules or MCP config files are empty, the corresponding output sections will also be empty.
Import from an existing tool config produces incomplete results
Not all features of every tool config format are fully supported by the importer. After running 'rulesync import', manually review the generated .rulesync/ files and add any entries that were not captured, then re-run 'rulesync generate' to produce the final output.
