This Skill helps developers avoid common pitfalls in input validation and data modeling by promoting a "parse, don't validate" approach, leading to more robust and maintainable code.
Use the parse-dont-validate skill to refactor a function that currently validates user input with boolean flags into one that uses discriminated unions.

Type safety at system boundaries improves by parsing unstructured data into structured types, making illegal states unrepresentable and shifting error detection to compile time.
Refactoring input validation functions involves replacing boolean flags with discriminated unions, ensuring data types correctly represent domain logic and preventing invalid states.
Type-driven design is needed when handling loosely typed string data or modeling domain logic, ensuring robust data integrity and reducing runtime errors through compile-time guarantees.
Yes, this approach applies to code review by providing principles to improve function signatures, error handling, and data type design for more maintainable software.
Type-driven design requires careful upfront data modeling and may not eliminate all runtime errors; it focuses on preventing illegal states through compile-time guarantees rather than dynamic checks.
Yes, it provides refactoring guidance for improving domain logic modeling and data types, transforming unstructured inputs into strongly-typed structures to reduce error-prone designs.
