Go developers often build software that fails silently or crashes due to improper error handling. This skill provides proven patterns for returning errors, wrapping with %w, designing sentinel and structured error types, and enforcing consistent error messaging and logging to improve reliability and debuggability.
Implement robust error handling in your Go code using the patterns described above.

Wrap errors in Go by using the %w verb with fmt.Errorf to preserve the original error while adding context. This creates an error chain that allows errors.Is and errors.As to traverse and match specific errors across package layers.
Handle sentinel errors in Go by defining specific error values and checking them with errors.Is. This pattern ensures precise error matching and allows services to handle expected failure states without comparing error strings directly.
Use structured error types in Golang when you need to carry additional data or context about a failure. The errors.As function unwraps these structured types, enabling type-specific handling and logging across I/O, network, or filesystem API layers.
Propagate errors across Go package layers by returning the error as the last return value and wrapping it with %w at each boundary. This standardizes error propagation, preserves the error chain, and improves service debuggability without silent failures.
Go programs fail silently when errors from network or filesystem APIs are ignored or improperly handled. Implement consistent error checking, wrap errors with context using %w, and enforce structured logging to diagnose and prevent silent failures.
