Ruler Reaches 2.7K Stars — One Tool to Apply the Same Rules Across All AI Coding Agents

GitHub·medium signal

intellectronica/ruler has hit 2,701 stars by solving config fragmentation: it lets developers define coding rules once and automatically distributes them to Claude Code, Codex, Cursor, Copilot, Windsurf, and other agents via their respective config files (CLAUDE.md, AGENTS.md, .cursorrules, etc.). The TypeScript tool uses a `ruler apply` command to sync a single source of truth across all agents. As teams adopt multiple coding agents simultaneously, maintaining consistent rules without manual duplication is becoming a real operational pain point.
