Field notes
Installation is described as dropping the files into a repository; the page does not claim they enforce behavior or auto-load in every setup. Results are split by tool and behavior: for example, Claude Code showed no change on uncommitted-work checks, while the async-params rule showed no difference because the agent already got it right. The site says several included rules remain unmeasured.
