Ruler — apply the same rules to all coding agents
Ruler is a TypeScript MCP server and CLI tool that solves a specific multi-agent coordination problem: developers maintaining separate instruction files for each AI coding assistant end up with duplicated, inconsistent configurations across their projects. Ruler introduces a single `.ruler/` directory of Markdown files as the authoritative source, then automatically generates the correct configuration files for each supported agent, including `CLAUDE.md` and `.mcp.json` for Claude Code, `.cursor/mcp.json` for Cursor, `.github/copilot-instructions.md` for GitHub Copilot, `.aider.conf.yml` for Aider, and equivalents for over a dozen other tools. It also propagates MCP server settings across agents that support them and handles nested `.ruler/` directories for monorepos or projects with distinct components. A `ruler.toml` file lets teams specify which agents to target and customize output paths. The `.gitignore` automation keeps generated files out of version control. Teams using multiple AI coding tools simultaneously will find the most value, particularly when onboarding new agents without rewriting existing guidance.
