SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents large, risky feature drops by enforcing a thin-slice workflow that keeps the system working and testable after every increment.

Core Features & Use Cases

  • Thin Vertical Slices: Break multi-file features into end-to-end steps so each increment delivers a complete user-visible slice (e.g., create, list, edit, delete flows).
  • Test-Driven Increment Loop: After each slice, implement the smallest complete piece, run tests (or add them), verify behavior, and only then move on.
  • Slicing Strategies for Uncertainty: Use contract-first or risk-first sequencing when backend and frontend must move in parallel or when the riskiest component should be validated early.

Quick Start

Use incremental-implementation to implement a multi-file feature by executing one vertical slice at a time, running tests and verifying the result after each slice before continuing.

Frequently Asked Questions about incremental-implementation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I break down a multi-file feature for incremental development?▼

Incremental development breaks multi-file features into thin vertical slices, delivering a complete user-visible step like create or edit flows so the system stays working after each increment.

What is the best way to keep a system testable during a large refactor?▼

Keep a system testable during a large refactor by implementing changes in thin vertical slices, running tests after each step to verify behavior before moving to the next increment.

How do I manage backend and frontend development moving in parallel?▼

Manage parallel backend and frontend development using contract-first or risk-first slicing strategies, validating the riskiest component early to coordinate independent layer progression.

When should I use vertical slicing instead of a large feature drop?▼

Use vertical slicing instead of a large feature drop when multi-file changes span database, API, and UI layers, requiring stepwise implement-test-verify-commit execution with rollback-friendly boundaries.

Can I apply incremental implementation to database and API layer changes?▼

Yes, incremental implementation applies to parallel backend and frontend tasks across database, API, and UI layers, enforcing strict scope discipline and safe defaults during multi-file development.

Why does my feature flag workflow need rollback-friendly commit boundaries?▼

Rollback-friendly commit boundaries are needed in a feature flag workflow because they ensure each vertical slice remains independently verifiable and safely revertible if tests fail.
