m13-domain-error

What it does: This skill helps plan how a computer program written in Rust should react when something goes wrong, such as a failed network request or a bad piece of input. It sorts errors into groups based on who needs to see them, for example a friendly message for an everyday user versus detailed technical information for a developer or the technical operations team. It also helps decide whether an error should be automatically retried after a short wait, whether the program should fall back to a safer default, or whether it should stop and alert a person. When to use it: Use it when designing how a Rust application handles failures and errors, especially when deciding what message different types of users should see, or when building automatic retry or fallback behavior for things like network or payment failures.
