SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Large features implemented in one pass produce bugs that are hard to locate, broken builds between steps, and commits that are impossible to review or revert. This Skill enforces an incremental workflow where every change is built, tested, and committed in small working slices. ## Core Features & Use Cases - Vertical Slicing: Breaks features into complete end-to-end paths (database migration, API route, UI form) so each slice leaves the system in a working, testable state. - Risk-First Ordering: Tackles the riskiest integration first so failures surface before significant effort is invested. - Scope & Simplicity Discipline: Prevents scope creep, premature abstraction, and unrelated refactors through explicit implementation rules and red-flag detection. - Use Case: When adding a full CRUD feature to a Next.js app, implement create, list, edit, and delete as four separate tested slices instead of one 500-line change, keeping the build green after every commit. ## Quick Start Ask the AI to implement the new feature incrementally in small tested slices, committing after each working step.

Frequently Asked Questions about incremental-implementation

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

FAQPage Schema
How do I implement a large feature without breaking the build?▼

Break the feature into thin vertical slices where each slice is a complete path through the stack, such as one CRUD operation. Test and commit after each slice so the build and test suite stay green between increments.

What is vertical slicing in software development?▼

Vertical slicing builds one complete path through all layers of the stack, such as database migration plus API route plus UI form, rather than completing one layer at a time. Each slice delivers working, testable functionality.

When should I not use incremental implementation?▼

Skip it for single-file, single-function changes where the scope is already minimal. The overhead of slicing only pays off when a change touches multiple files or exceeds roughly 100 lines of code.

How do I hide an unfinished feature in production code?▼

Use feature flags that gate the new code behind an environment variable, such as checking a FEATURE_TASK_SHARING variable before rendering new UI. This keeps incomplete work merged but invisible until ready.

Why do bugs compound when testing everything at the end?▼

A bug in an early slice silently corrupts every slice built on top of it, making the root cause hard to isolate among hundreds of changed lines. Testing each increment catches defects at the point of introduction.
