Introducción

Best for: teams using multiple coding agents who want consistent instructions and MCP config propagation across tools

Works with: Node.js + npm/npx, a repo with agent config files (CLAUDE.md/AGENTS.md/.cursor), optional nested project structures

Setup time: 10 minutes

Quant Data

Supports Claude Code, Cursor, Codex, Copilot and more (repo)
Setup time ~10 minutes

How to Use It Well

Start with a short .ruler/AGENTS.md that encodes your real workflow (tests, style, safety). Then turn on nested mode only where components truly differ.

Adoption Checklist

Start with one real task and keep the scope narrow
Capture a baseline: time-to-first-success and output quality
Version your config/skills so teammates stay in sync

Guardrails

Generated files should stay generated. Avoid manual edits downstream; treat .ruler/ as the only editable surface.

FAQ

Q: Is it production-ready? A: The README labels it as a beta research preview; adopt it in one repo first and keep rollbacks simple.

Q: How does it avoid drift? A: Rules live in .ruler/ and Ruler regenerates downstream config files, so you maintain one source of truth.

Q: Can it handle monorepos? A: Yes. The repo documents nested rule loading for multiple .ruler/ directories with scoped configs.
