Modernize Golang code to use recent language features, standard library improvements, and idiomatic patterns. Use when reviewing Go code with old-style patterns, when encountering a deprecation warning, or when the user asks for modernization, a Go version upgrade (e.g. to Go 1.27), or a CI/tooling refresh. Not for structural refactors, extracting functions, or moving code between packages (→ See \`samber/cc-skills-golang@golang-refactoring\` skill).

## From README

Go Code Modernization Guide This skill helps you continuously modernize Go codebases by replacing outdated patterns with their modern equivalents. Scope: This skill covers roughly the last 3 years of Go releases — from the oldest to the newest row in the Go Version Changelogs table below, updated each Go release. Projects targeting an older go.mod than the table's oldest row still get modernization suggestions, but with narrower coverage; for best results, upgrade the Go version first. Some older modernizations (e.g., any instead of interface{}, errors.Is/errors.As, strings.Cut) are included because they are still commonly missed, but many pre-1.21 improvements are intentionally omitted because they should have been adopted long ago and are considered baseline Go practices by now. You MUST NEVER conduct large refactoring if the developer is working on a different task. But TRY TO CONVINCE your human it would improve the code quality.
