Codebase Design

Concentrate complexity behind useful interfaces. A good module gives callers substantial capability while keeping knowledge, change, bugs, and verification local.

When another skill loads this one, apply the vocabulary and analysis below inside that skill's workflow and output format. When invoked directly, complete the full workflow and return the module-design report.

Workflow

1. Frame the module

Identify the module under review, its responsibility, callers, dependencies, public entry points, observable behavior, and constraints. A module may be a function, class, component, package, service, feature, or tier-spanning slice.
