This Skill helps developers migrate existing error handling patterns (like try/catch and Promise rejections) to a more robust and type-safe system using Result types, aligning with railway-oriented programming principles.
Result.try, async/await to Result.tryPromise, and null checks to Result.Use the better-result skill to migrate the provided try/catch block to use Result.try.

You refactor existing try/catch blocks using `Result.try`, converting thrown exceptions into typed errors to achieve type-safe error handling and adopt railway-oriented programming patterns.
Railway-oriented programming is a functional pattern where operations return explicit Result types representing success or failure, preventing uncaught exceptions and forcing developers to handle typed errors explicitly for more robust, predictable code execution.
Yes, you can convert Promise rejections to Result types using `Result.tryPromise`. This transforms asynchronous error handling by mapping rejected promises into typed errors, ensuring robust boundary checks in async/await code.
The best way to replace null checks is to transform imperative checks into Result-based patterns. This migration analyzes code boundaries and provides transformation strategies, turning null checks into explicit success or failure tracks.
Yes, refactoring to Result types works for legacy Node.js services that use extensive try/catch blocks. The migration analyzes existing code for error categories and provides targeted transformation strategies for imperative checks and callback structures.
