A Hacker News post details a Spec‑Driven Development workflow that extracts more value from Claude‑based coding agents. The method splits work into two dimensions: multi‑step spec generation—requirements, analysis, design—and sequential subtask execution. Clearing the context after each spec and subtask keeps prompts short, reducing token cost and improving agent focus.

The approach writes each spec to disk, creating a persistent layer that survives across runs. Persisted specs act as a reference point, allowing developers to spot divergences early when the model misinterprets intent. Layer‑by‑layer delivery catches errors before they compound, making debugging more systematic.

A community‑maintained Claude plugin implements this workflow and is available on GitHub repo at https://github.com/sermakarevich/sddw. Users can clone the repository to experiment with the decomposition strategy and benefit from the clear context handling. The project demonstrates a practical path to lower API spend while maintaining code quality.
