Ruler is an orchestration tool designed to eliminate configuration drift in multi-agent development environments. By centralizing instructions and Model Context Protocol (MCP) settings within a dedicated .ruler/ directory, it ensures that project-specific rules, coding standards, and server connections are consistently applied across a wide array of tools including Claude Code, GitHub Copilot, Cursor, and Windsurf. It features intelligent merge strategies for existing configs, automated backup/revert functionality, and support for both local and global configuration profiles, making it essential for teams using diverse AI stacks.
