Skeleton code translates a mental model into a concrete system frame. Like the framing of a house, it establishes component boundaries without implementing every detail, so the design can become operational without premature complexity. The structure may change as implementation reveals missing, unnecessary, or differently shaped parts. section 2.0
Build a useful skeleton by making the system's shape executable:
- Identify the main components and create their files or packages, such as Task, Worker, Manager, and Scheduler. section 2.0
- Define task states and component responsibilities before filling in operational behavior. section 2.7
- Use interfaces where interchangeable implementations are expected, such as schedulers with different behavior. section 2.7
- Compile and run a small test program so the structure proves it can build, start, and expose basic interactions. section 2.0 section 2.7
A generated worker command
The command `cobra-cli add worker` creates a Go command skeleton with a Run function, initialization hook, and registration with the root command. Running `worker` initially prints `worker called`; flags and worker startup behavior can then be added incrementally. section 12.6
. ├── main.go ├── manager │ └── manager.go ├── node │ └── node.go ├── scheduler │ └── scheduler.go ├── task │ └── task.go └── worker └── worker.go
A directory tree makes the skeleton's boundaries visible: the main program coordinates separate manager, node, scheduler, task, and worker components. section 2.0
