Tip: Ruler — One Rules Directory for Claude Code, Cursor, Copilot, and Every Other Agent

GitHub·medium signal

Ruler (2.6K stars) solves multi-tool rule fragmentation: store instructions once in a .ruler/ directory as Markdown files, and Ruler automatically distributes them to CLAUDE.md, .cursorrules, AGENTS.md, and other agent config files. Supports nested rule loading for monorepos. For teams using multiple AI coding tools simultaneously, this eliminates the drift between agent-specific instruction files that causes inconsistent behavior.
