render-code-shape
citypaul/.dotfiles
Render the shape of code — module boundaries, the types that cross them, signatures, and a cited call graph — for code that already exists or a change about to be built. Every name, type, and path is read from source and cited, or marked NEW; bodies collapse to one line of intent. Use when asking how something composes, tracing what a request actually touches, pseudocoding a change before implementing it, onboarding to an unfamiliar path, or producing the shape a plan and its tests will be checked against. Read-only: the render is the deliverable, never the edit. For judgments about whether the shape is good see codebase-design; for where files should live see structure-codebase; for a rendered picture see diagrams; for fault localization see debugging.
