-Whippet keeps your code, your dependencies, your config, and your docs from quietly bloating and drifting — **automatically**. Install it once and it runs on its own: an always-on discipline that writes the least code that actually works, plus quiet background checks that flag a dependency the platform already covers, a Claude setup that has drifted, or docs that fell behind the code. The one command, `/whippet-config`, runs the full setup audit on demand.
