error-handling

What it does: This skill shows how to handle mistakes and problems in code across different programming languages like TypeScript, Python, and Go. It explains how to create organized error types, catch problems early, retry failed operations, and show helpful messages to users. When to use it: Use this when building any software that needs to be reliable and handle problems gracefully. It helps when you are connecting to outside services that might fail, or when you need to show users what went wrong in a way they can understand. This skill prevents silent failures where problems happen but nobody knows about them.
