What it does
go-ultimate is an agent skill that gives Claude Code, Codex, Cursor and OpenCode one set of Go conventions. It covers architecture, modern Go, testing, code review, MCP servers and agent patterns, and points each task to the matching guidance and checklist. Where its rules conflict with generic Go style guides, its own rules take precedence.
