This is a structured Go code reviewer that enforces a four-step workflow: check go.mod for the version baseline, read full function context (not just diffs), scope the relevant checklist blocks, then run verification protocol before reporting anything. It covers the usual suspects like error handling and goroutine leaks, but also includes version-gated advice for Go 1.18+ generics, 1.21+ slog, and 1.22 loop semantics. The severity calibration is sensible, goroutine leaks and race conditions block merge while missing doc comments are minor. What I appreciate is the explicit "Valid Patterns" section that tells it not to flag intentional underscore assignments or functional options, which cuts down on false positives. Use this when you want methodical Go reviews that respect idiomatic code instead of blindly applying rules.
