skeletoncode

Skeleton code is a minimal set of source files that defines the structure and interfaces of a software project without implementing full functionality. It provides the scaffold for development, outlining components such as modules, classes, functions, data structures, and the intended control flow. Skeleton code typically includes stubs for unimplemented methods, placeholder data, and a basic execution path that compiles and can run a simple test.

Purpose and uses include guiding system design, enabling parallel work, and establishing a shared API or contract early in a project. By presenting the expected interfaces and module boundaries, skeleton code helps teams agree on responsibilities, data formats, and interaction patterns before detailed implementation begins. It is commonly produced by scaffolding tools, templates, or code generators, and may be refined as requirements evolve.

Common elements are a project structure with directory layout, minimal class or function definitions, comments describing intended behavior, and test stubs. It often includes placeholder return values or exceptions for unimplemented paths and basic wiring to show how components interact.

Lifecycle and evolution: skeleton code is expected to be progressively replaced with full implementations. It may be updated as design decisions firm up, tests are written, and documentation is expanded. It is related to but distinct from prototypes or throwaway code, as skeleton code is intended to be maintained and developed rather than discarded.

Benefits and cautions: it accelerates initial planning and integration but can become misleading if left unchanged and out of date. Care should be taken to maintain clarity of the intended design and to replace placeholders promptly as work proceeds. Related concepts include scaffolding, boilerplate, and code templates.
