# Rules Evaluator

Find out which of your rules still earn their place

## What this does

You wrote some rules for Claude to follow, and now you are not sure they are doing anything. This walks through them one at a time, checks whether their file patterns actually match anything in your project, and asks you if each rule is still worth keeping. It can rewrite them based on what you say. Handy when you first set rules up, or months later.

### Top 3 things it does for you

- Check that my rules match real files
- Fix rules that fire constantly or never
- Do a spring clean of my rule set

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 Rules Evaluator

This audits the rule files in your project, looking at how they are put together, whether their path patterns are valid, and whether they are of any real use. Each pattern is resolved against the files actually in your project, so you can see what a rule would and would not catch.

It then asks you, rule by rule, whether the rule is still relevant and useful, and can update rules in place based on your answers.

Reach for it when you are setting rules up for the first time, when a rule fires far too often or never fires at all, or when you want a periodic tidy-up of the whole set.

## Questions

### Is Rules Evaluator safe to install?

AIR scanned this exact version of Rules Evaluator and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 73e1dec1733c, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/eval-rules.

### How do I install Rules Evaluator?

Open https://airmarket.ai/app/eval-rules on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
