Go projects often suffer from inconsistent, ad-hoc logging that makes debugging and tracing requests difficult. This Skill promotes using the standard library log/slog to create structured, context-aware logs across services, handlers, CLIs, and background jobs.
Initialize a logger with slog and attach it to your context, then use its level methods to emit structured logs at the call sites.

Structured logging in Go uses the standard log/slog package to create context-aware logs. You initialize a slog.Logger, attach it to your context, and emit structured fields with Debug, Info, Warn, or Error methods for consistent observability.
The best way to attach a slog logger is to store the *slog.Logger instance within the standard Go context. This allows handlers and background jobs to extract consistent logging fields like request IDs without passing the logger explicitly through every function.
Yes, log/slog is fully suitable for background jobs and CLIs in Go. It provides level-aware logging with Debug, Info, Warn, and Error methods to ensure consistent severity control and traceability across all production workflows.
Go service logs lack traceability due to inconsistent, ad-hoc logging. Implementing standardized structured logging with log/slog aligns your logs with request IDs, user identifiers, and component names for reliable debugging.
No external dependencies are required. The log/slog package is part of the standard Go library, allowing you to implement context-rich observability and structured logging directly within your services.
