SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Large, multi-file changes become risky, difficult to test, and hard to revert when implemented in one pass; this Skill provides a disciplined approach to deliver changes in small, verifiable increments so the system remains buildable and testable at every step.

Core Features & Use Cases

Thin Vertical Slices: Implement one end-to-end piece of functionality at a time (DB, API, UI) so each increment delivers a working feature.
Safety Checks & Rollback Discipline: Require tests, builds, type checking, linting, descriptive commits, feature flags for incomplete work, and rollback-friendly migrations.
Use Case: Building a new CRUD feature across backend and frontend by shipping the database schema, API, and UI in separate, tested slices to reduce risk and simplify reviews.

Quick Start

Implement the next smallest vertical slice by making the minimal backend or API change, add or run tests to verify it, ensure the build and type checks succeed, and commit with a descriptive message.

FAQPage Schema

How do I break large refactoring changes into smaller, testable increments?▼

Ship large refactoring changes incrementally by breaking them into thin vertical slices that each compile and pass tests. This keeps the codebase working and testable at every step, enforcing build checks, descriptive commits, and rollback-friendly migrations.

What is vertical slicing when implementing multi-file features across database, API, and UI layers?▼

Vertical slicing implements one end-to-end piece of functionality at a time across database, API, and UI layers. Each working slice passes continuous integration independently, reducing risk and simplifying code reviews for multi-file features.

How do I ship incomplete backend and frontend features safely using feature flags?▼

Use feature flags to merge incomplete backend and frontend work safely while keeping it disabled in production. This rollback-friendly discipline ensures each incremental slice compiles and passes CI without exposing unfinished functionality.

How do I maintain commit discipline during incremental implementation?▼

Maintain commit discipline by writing descriptive messages for each minimal vertical slice. Every commit must pass tests, build checks, and type checking, ensuring continuous integration remains green throughout the incremental implementation.

When should I use incremental implementation for a new CRUD feature?▼

Use incremental implementation when building a new CRUD feature across backend and frontend. Ship the database schema, API, and UI as separate, tested slices to reduce integration risk, maintain a buildable state, and simplify rollback.

What are the limitations of delivering large changes in a single pass?▼

Large, multi-file changes implemented in one pass become risky, difficult to test, and hard to revert. Without incremental slicing, the system cannot maintain a working or testable state at every step, complicating continuous integration and code reviews.
