About
This skill provides a comprehensive set of rules and architectural patterns to ensure your TypeScript 5.x codebases achieve the highest possible level of type safety and maintainability. It mandates the use of strict compiler flags, bans permissive types like 'any' or 'object', and promotes functional programming principles alongside modern tooling like Biome and Vitest. By integrating these standards, Claude helps you catch errors at compile-time, ensure consistent testing structures with co-located files, and maintain clean, predictable code across complex enterprise or open-source projects.
