Applying Vertical Slice Architecture

Quality score: 70/100 · Category: Engineering · Sub-category: architecture

type:review

Designs, reviews, and migrates codebases using Vertical Slice Architecture (VSA) — organizing by business capability instead of technical layer. Produces slice boundaries, folder structures, sharing strategies, and migration plans. Use when designing a new VSA codebase, reviewing an existing VSA codebase for anti-patterns, migrating from layered architecture to vertical slices, deciding slice granularity or folder organization, handling shared code across slices, or when the user mentions vertical slices, feature folders, or organizing by use case.
