principle-redesign-from-first-principles

What problem does it solve? When a new requirement arrives, teams often bolt it onto an existing design, creating layered patches that erode the architecture. This Skill guides the AI to instead redesign the affected code as if the requirement had been known from the start, preserving design coherence and option value. ## Core Features & Use Cases - Holistic Design Review: Reads all affected files to understand the current design before proposing changes. - First-Principles Redesign: Asks what the system would look like if built from scratch with the new requirement in mind. - Full Propagation: Updates every reference including types, docs, examples, and rationale sections. - Use Case: You need to add multi-tenancy to an app originally designed for a single tenant. Instead of scattering tenant checks everywhere, the Skill rethinks the data model and API boundaries as if multi-tenancy was a day-one assumption, then delivers the redesign incrementally. ## Quick Start Ask the AI to integrate a new requirement into the existing design by redesigning from first principles rather than bolting it on.
