Your CLAUDE.md and AGENTS.md disagree and you don't know it

Automated excerpt

Every agent tool wants its own config file. So I built ruleherd. npx ruleherd reads every instruction file in a repo and reports: DEAD CMD: npm run x where no package. json has an x script STALE: "react 17" in the rules while package. json installs react 19 DEAD GLOB: a . mdc rule whose globs point at a deleted directory (Cursor silently never loads it) Score out of 100. I hand-sync one universal rules file into five tool locations.
