golang-modernize

separate

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).

When to use

• Modernizing Go code
• Replacing deprecated packages
• Upgrading language features
• Standard library upgrades
• Updating testing patterns
• Refreshing tooling and infra
• Go version upgrade
• CI pipeline modernization

When not to use

• Structural refactors
• Extracting functions
• Moving code between packages
