Eval Rules

Category: Engineering · Sub-category: engineering-misc · Last updated: 2026-05-21

type:audit

Audit .claude/rules/ files for structural correctness, glob validity, and real-world usefulness. Resolves each paths: pattern against actual project files, then asks the user whether each rule is still relevant and useful. Can update rules in-place based on answers. Use when setting up rules for the first time, debugging rules that fire too often or never, or doing a periodic rules hygiene pass.

From the source SKILL.md

Discover all rule files, validate their structure and glob patterns against the real project, then run an interactive session to confirm (or improve) each rule with the user.
