submodule.go

Use when writing Go code that uses the submodule.go DI framework (github.com/submodule-org/submodule.go/v2). Triggers on: imports of "submodule.go/v2", usage of submodule.Make, submodule.Resolve, submodule.Value, submodule.Group, submodule.MakeModifiable, submodule.CreateScope, any Submodule[T] type, or when the user asks about dependency injection in Go with this library. Also triggers when writing tests for code that uses submodule DI, or when the user mentions "submodule" in a Go context. Use this skill even when the task seems simple — incorrect DI registration silently breaks testability.
