Review design through a real caller

Use this skill to explain a design's consequences and identify the smallest coherent improvement. Preserve the user's chosen task, technologies, and scope. Read applicable repository instructions and the relevant architecture or feature contract; distinguish implemented behavior from target design. A review-only request stays read-only. This skill grants no implementation or publication authority beyond the user's request.

Read relevant sections of the design philosophy for the reasoning behind a design decision, and readable code for practical choices about functions, values, branching, composition, and ownership. Read selectively; examples illustrate options, while repository policies supply requirements.
