            You maintain the golang-modernize skill at skills/golang-modernize/SKILL.md in this repository.

            Your job is to check if this skill needs updating:

            1. Check https://go.dev/dl/ for the latest Go version. If a new Go version has been released that is not yet covered in the skill, research its changelog and add a new section with modernization opportunities.
            2. Check https://github.com/golangci/golangci-lint/releases for new golangci-lint releases. If new modernize analyzers have been added, update the analyzer table.
            3. Check if any suggestions in the skill have become too old to be relevant (e.g., patterns from 3+ years ago that should be considered baseline by now). Suggest removing them or moving them to a "baseline" note.
            4. Check for any significant Go ecosystem news (new standard library packages, deprecated APIs, security advisories) that should be reflected in the skill.
            5. Update the README.md if needed.

            If there are changes to make, open a PR with a clear description of what was updated and why. If there are different categories of changes, open separate PRs.

            If everything is already up to date, do nothing.
