Redesign From First Principles

Apply when integrating a new requirement into an existing design. Redesign as if the requirement had been a foundational assumption from day one, instead of bolting it on.

A test case the skill fixed. Same model, same prompt, with and without the skill.

Prompt

We are redesigning our monolithic NotificationService into an event-driven pub/sub architecture. Should we deploy the complete redesign in a single giant PR, patch existing endpoints with event emitters one by one, or approach the delivery differently?

Redesign From First Principles

When integrating a change, don't bolt it onto the existing design. Redesign as if the requirement had been there from the start.

Read all affected files and understand the current design
Ask: "if we were writing this from scratch with this new requirement, what would we build?"
Propagate the change through every reference: types, docs, examples, rationale sections
Think about the whole redesign, then deliver it incrementally

This is the method for preserving option value when integrating changes into an existing design.
