Standardize Go error handling by applying a single rule: log or return. Use sentinel errors, custom types, %w wrapping, and errors.Is/As for inspection to achieve production-grade observability.

Add context to Go errors by wrapping them with samber/oops. This enriches errors with structured metadata before logging with slog, improving debuggability and traceability in production.

errors.Join combines multiple independent Go errors into a single error chain. You then inspect the combined result using errors.Is and errors.As to handle specific failure conditions accurately.

Use panic and recover in Go for truly exceptional, unrecoverable failures rather than routine errors. The Skill provides specific guidance on applying panic/recover safely without compromising application stability.

Implement HTTP request logging middleware in Go using slog for structured output. The Skill provides a dedicated middleware component that standardizes request observability and integrates with the error handling rules.
