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
- Init -
rulesync initcreatesrulesync.jsoncconfig and.rulesync/directory with sample rules - Write rules - Add shared AI rules in
.rulesync/rules/, MCP configs in.rulesync/mcp/, commands in.rulesync/commands/ - Generate -
rulesync generateproduces tool-specific files (CLAUDE.md, .cursorrules, .github/copilot-instructions.md, etc.) - Verify -
rulesync generate --dry-runpreviews changes;--checkvalidates files are up to date (useful in CI)
