# Anvil

> AI rules audit engine — score, detect drift, and improve rules in any AI-assisted codebase.

Anvil audits CLAUDE.md, .cursor/rules, AGENTS.md, and other AI rule files for coverage gaps, drift, conflicts, and format compliance. Zero-install, no API keys required for the baseline audit. Works with any codebase.
