hallmark

Hallmark is a devtool that trains AI coding assistants like Claude Code, Cursor, and Codex to produce clean, intentional code by enforcing anti-“AI-slop” design principles. It’s for developers who want to maintain high code quality and avoid the generic, bloated patterns that AI models often default to. Its interesting angle is treating AI output as a craft discipline, giving devs a tool to shape model behavior rather than passively accepting its defaults.
