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 painful to review or roll back. This Skill enforces a disciplined increment cycle so every change lands in a working, tested state. ## Core Features & Use Cases - Increment Cycle: Implement, test, verify, commit, then move to the next slice so the codebase never sits in a broken state. - Slicing Strategies: Choose vertical slices, contract-first slicing for parallel backend/frontend work, or risk-first slicing to prove uncertain pieces early. - Scope and Simplicity Rules: Enforces one logical change per commit, feature flags for incomplete work, safe defaults, and rollback-friendly changes. - Use Case: When adding a full CRUD feature across database, API, and UI, deliver it as four tested slices (create, list, edit, delete) instead of one large unverified change. ## Quick Start Ask the AI to implement the next task from your plan incrementally, starting with only the database schema and API endpoint, running tests and build before committing each slice.

FAQPage Schema

How do I implement a large feature incrementally?▼

Break the feature into thin vertical slices where each slice delivers working end-to-end functionality. For each slice, implement the smallest complete piece, run tests, verify the build, commit with a descriptive message, then move to the next slice.

What is vertical slice development in software engineering?▼

Vertical slicing builds one complete path through the entire stack per increment, such as database plus API plus UI for a single operation. Each slice leaves the system working and testable, unlike horizontal layers that deliver nothing usable until all layers finish.

When should I not use incremental implementation?▼

Skip it for single-file, single-function changes where the scope is already minimal. The increment cycle adds overhead that only pays off when a change touches multiple files or feels too large to land safely in one step.

How do feature flags help with incomplete features?▼

Feature flags let you merge small increments to the main branch without exposing unfinished work to users. Gate the new code behind an environment variable or config check that defaults to off, then enable it when the feature is complete.

Why should each commit contain only one logical change?▼

Mixing a feature, a refactor, and config changes in one commit makes reviews harder and bugs harder to isolate. Separate commits keep each change independently revertable and make it clear which change caused a failure.
