Standardize Go error handling by defining doterr sentinels with contextual metadata, enforcing consistent propagation patterns across packages without relying on fmt.Errorf. This approach creates traceable, composable errors for refactoring existing codebases or building stable public APIs.

Replacing fmt.Errorf with doterr sentinels enforces safe error composition and contextual metadata attachment. Using doterr.WithErr ensures errors propagate with consistent context across package boundaries, preventing the untraceable error wrapping that often accumulates in Go projects.

The best way to add contextual metadata to Go errors is using doterr sentinels and the doterr.WithErr function. This method attaches context at the boundary and documents sentinels with metadata, providing stable API behavior and safe error composition without fmt.Errorf.

Yes, you can refactor existing Go codebases by replacing inconsistent error returns with doterr sentinels and attaching context at the boundary. This standardizes error definitions and aligns error propagation across packages using metadata-documented sentinels.

You need documented sentinels for public Go APIs when defining new errors that require stable behavior. Using doterr sentinels with contextual metadata ensures safe composition and consistent propagation, avoiding the instability of fmt.Errorf in public interfaces.

Yes, doterr integrates with Go context by attaching contextual metadata to sentinels at the boundary. This enforces consistent error propagation across packages, replacing fmt.Errorf with doterr.WithErr to maintain traceable and standardized error handling.
