Google has launched Code Wiki, a platform that keeps documentation for code repositories updated in real-time. It allows developers to access interactive documentation, diagrams, and an AI chat assistant to quickly understand complex code without getting bogged down in static files.

A collection of reusable rules and knowledge documents designed for AI coding assistants like Claude Code and Cursor, facilitating development workflows, code quality analysis, problem solving, documentation generation, and automation. The repository provides a unified .mdc format for compatibility across different tools, encouraging contributions from users to enhance the library of actionable rules.
