# Rulesync

Write your coding rules once, have every assistant read them

## What this does

You use several AI coding tools and each one wants its rules in a different file, so they drift apart. This keeps one source and generates each tool's own file from it, and it can pull in rules you already have. Reach for it when you are tired of copying the same instructions into a dozen places.

### Top 3 things it does for you

- Keep one set of rules for all my coding tools
- Push my rules out to each assistant's own file
- Import rules I already have scattered about

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Rulesync

This generates and syncs AI rule configuration files from a single source, producing the per-tool files such as .cursorrules, CLAUDE.md and copilot-instructions.md across a wide range of coding tools.

It handles syncing rules, running its own commands, importing rule files you already have and generating new ones. It is for anyone keeping shared AI coding configuration across more than one tool.

## Questions

### Is Rulesync safe to install?

AIR scanned this exact version of Rulesync and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 84613b709fdb, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/rulesync.

### How do I install Rulesync?

Open https://airmarket.ai/app/rulesync on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/dyoshikawa/rulesync/tree/84613b709fdb99eb7bff4fe2c3c41e9b0918dc82/skills/rulesync. Install from that link, not the branch.
