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.
