RepoGuard – CLI to stop Cursor and Copilot from bypassing architecture

RepoGuard launched as a command-line tool that enforces architectural rules on code written by AI assistants including Cursor and Copilot, offering commands such as `npx repoguard init`, `npx repoguard audit`, `npx repoguard diff`, `npx repoguard hook install`, and `npx repoguard rules`. The tool targets four failure modes the project lists — bypassing layers by calling Prisma/ORM directly inside UI components and controllers, hardcoding mock credentials and API tokens, injecting direct `window` or `localStorage` calls in Server Components, and scattering `: any` to pass compilation — and scores repository architecture health from A+ to F. RepoGuard generates `.cursorrules`, `CLAUDE.md`, and Windsurf rules files and installs a Git hook to block AI drift before commit, with 8 active architectural rules available to list.
