Grip - A git hook that quizzes you on your diff before you push.

grip is a pre-commit-style hook for the AI coding era. When you commit or push, it reads your diff and asks five questions about it: behaviour, motivation, edge cases, risk, testing. You answer in the terminal. You get a Grip Score out of 100. Under your pass mark, the push is blocked with notes on what to re-read. • One-line curl install, prebuilt binaries for Linux and macOS • pre-commit framework support, .grip.toml config, your own pass mark and difficulty

faah! get mocked on terminal errors - A shell-attached tool to play "faah" whenever you err.

- Is it AI-powered? -- No. - Does it use LLMs to suggest a fix? -- No. - Does it improve productivity? -- Arguably, it makes it worse. I built faah. It’s a small Python tool that plays the "faah" meme sound whenever you hit exit code 127 (command not found) or 126 (not executable). Not every vibe-coded project needs to change the world. Sometimes you just need a 300ms audio file to play when you type gti for the fifth time today.
