Introducing Code Wiki: Accelerating your code understanding- Google Developers Blog

Introduces Code Wiki, a platform that generates and maintains continuously updated, structured wikis for code repositories. It integrates with a Gemini-powered chat agent that uses the wiki as context to answer repository-specific questions. The system automatically regenerates documentation after code changes and links answers directly to relevant code files, classes, and functions. It also generates architecture, class, and sequence diagrams. A Gemini CLI extension for Code Wiki is announced for internal repositories.
