Intro

Rulesync distributes shared AI coding rules through npm, Homebrew, or a binary installer so Claude Code and similar tools stay aligned on one rule source.

Best for: teams struggling with rule drift across Claude Code, Gemini CLI, Codex-style tools, and shared coding standards

Works with: npm global installs, Homebrew, binary installers, shared agent rules, cross-tool coding-policy distribution

Setup time: 5-10 minutes

Main

Rulesync solves a practical governance problem: standards often exist, but each agent or client keeps a slightly different local copy.

Because installation is available through npm, brew, and a direct shell installer, it is easy to standardize even when contributors use different machines.

Use it when you already know your preferred rules and need reliable propagation, not when you are still debating what the rules should be.

Source-backed notes

  • README documents npm, Homebrew, and single-binary installation modes.
  • The project is explicitly framed as a utility CLI for AI coding agents.
  • It is referenced in Awesome Claude Code and Awesome Gemini CLI badges on the README.

FAQ

Q: Is Rulesync itself a rule set? A: No. It is a distribution utility for keeping rule sources synchronized.

Q: How can I install it? A: Via npm, Homebrew, or the release installer script in the README.

Q: When is it most useful? A: After a team already has shared standards and needs them applied consistently across tools.
