What does golang-error-handling do?
golang-error-handling is a skill that sets Go error-handling rules for Claude in three modes. Coding mode follows the rules while writing new code. Review mode checks a PR diff for swallowed errors, missing wrap context, log-and-return pairs and panic misuse. Audit mode splits a codebase across up to five sub-agents: error creation, wrapping, the single handling rule, panic and recover, and structured logging. Its fifteen rules include wrapping with %w, matching with errors.Is and errors.As, lowercase messages, errors.Join, slog over log.Printf, samber/oops for stack traces, and low-cardinality log messages. Reference pages go deeper on each area.

- You are adding error returns or wrapping in Go code
