SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Large features implemented in one pass produce bugs that are hard to locate, reviews that are hard to read, and rollbacks that are painful. This Skill enforces a disciplined increment cycle so every change leaves the codebase in a working, testable state. ## Core Features & Use Cases - Increment Cycle: Implement, test, verify, commit, then move to the next slice, keeping the build green between steps. - 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 building a task management feature, deliver create, list, edit, and delete as four separate end-to-end slices, each tested and committed, instead of one large unreviewable change. ## Quick Start Implement the next task from my plan incrementally, starting with just the database schema and API endpoint, and run the test suite after 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 the test suite, 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 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 the end.

When should I use feature flags for incomplete work?▼

Use feature flags whenever a feature is not ready for users but you need to merge increments to the main branch. Gate the new code behind an environment variable or config flag so incomplete work stays hidden while small commits keep flowing.

When is incremental implementation not needed?▼

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 big to land in one step.

Why should refactors and features be in separate commits?▼

Mixing refactors with features makes both harder to review and debug, since a regression cannot be attributed to one concern. Separate commits keep each change independently revertable and keep the history readable.
