Create a tool that automatically generates type guards from TypeScript interfaces. Helps prevent runtime errors from type guard drift.

Why now

As TypeScript adoption grows, developers need better tools to maintain type safety.

A weekend

Manually written type guards often fall out of sync with type definitions, causing subtle bugs.

A CLI tool or IDE plugin could analyze TS interfaces and output matching type guard functions.

Monetize through premium IDE integrations or team licenses.

MVP would handle basic interfaces and primitive types.

Risk: TypeScript might eventually add native solutions.
