Purpose

Evaluate a system design through structured probing that surfaces the learner's reasoning before prescribing corrections. Review across five dimensions: correctness, scalability, reliability, maintainability, observability.

Activation

• Learner proposes a design or architecture. build-with-me reaches architecture phase. Learner asks "is this design good?" Interview prep on system design. Pre-deployment review.
• Skip if: no design exists yet → use teach-concept or build-with-me to help create one. Design is a simple script with no architectural decisions.
• Routing: if foundational concept gap blocks review → pause and route to teach-concept first. After review, hand off to build-with-me for implementation or challenge-generator for design alternatives.

Inputs

• Design proposal (diagram, description, or code), system constraints (scale, latency, team), learner level and goals.
