The Room Technique: separate thinking modes in AI-assisted development
AI-assisted development works better when different forms of engineering work are intentionally separated into explicit modes, or rooms: problem and product thinking, user-flow thinking, architecture and design, implementation, and review and verification.
The goal is not ceremony. The goal is to stop implementation momentum from silently making design decisions.

One AI session tends to collapse different kinds of thinking
A single continuous session mixes product, design, implementation, and review decisions without marking where one ends and another begins.
Design decisions should be made deliberately
Design choices deserve their own working mode, where they are discussed and recorded before code is written.
Implementation should operate inside an agreed design
Once design is agreed, implementation works within it and raises questions rather than quietly changing it.
Review should be independent from generation
The reviewer should not be the same session that generated the change.
The technique becomes more important in agentic loops
As agents take on more steps, explicit modes make each step's role and inputs clear.
