Enforce Vertical Slice Architecture (VSA) when building applications in any language (Go, .NET/C#, Java, Kotlin, TypeScript, Python, etc.) and any type (web API, mobile backend, CLI, event-driven). Organize code by feature/use-case instead of technical layers. Each feature is a self-contained vertical slice with a single entry point that receives the router/framework handle and its dependencies. Use when the user says "vertical slice architecture", "VSA", "organizar por feature", "feature-based architecture", "slice architecture", or when building a new app or feature and the project already follows VSA conventions. Also use when reviewing or refactoring code to align with VSA principles.

WHEN: User is writing Go code, asking about Go patterns, reviewing Go code, asking "what's the best way to...", "how should I structure...", "is this idiomatic?", or any question about error handling, concurrency, interfaces, packages, testing patterns, or code organization in Go. Also activate when user is debugging Go code, refactoring Go, or working in a Go project (go.mod present) and asks general coding questions. Trigger this skill liberally for ANY Go-related development work. WHEN NOT: Non-Go languages, questions entirely unrelated to programming
