SUMMARY

What it does

This Agent Skill provides guidance for implementing changes incrementally, emphasizing thin vertical slices, testing each increment, and keeping the system in a working state. It includes strategies for slicing work (vertical, contract-first, risk-first), implementation rules (simplicity, scope discipline, one thing at a time, compilable state, feature flags, safe defaults, rollback-friendly), and checklists for verification. The skill is intended for software development tasks involving multi-file changes or large features.
