Specification-Driven Development
Specification-Driven Development is a software development methodology that places formal specifications at its core. The central concept is to produce clear, structured requirements specification documents prior to development, explicitly defining functional requirements, constraints, and acceptance criteria, which then guide the design, coding, and testing processes. This approach helps reduce requirements ambiguity, lower the risk of development deviation, and provides a unified reference baseline for team collaboration.

Influenced by OpenAI researcher Sean Grove's view that "specs are the new code," Pocock tried spec-driven development for several months, but code quality kept deteriorating, and he eventually abandoned the approach.
Pocock believes that the effectiveness of a methodology depends on the quality of the underlying environment: however detailed the spec, if the codebase itself is chaotic, the Agent will still produce more chaotic results.
Matt believes specification documents are not a panacea and that a maintainable code environment is the foundation; specification-driven development is better suited as an auxiliary means rather than a replacement for the foundation of a maintainable codebase.
Spec-driven development (SDD) uses Spec Kit to break work into explicit stages, each producing one file, with the flow: spec → clarify → plan → tasks → analyze → implement → verify.
In spec-driven development, rule one is that state is passed through files rather than chat, with the context cleared between each stage.
After generating code, it must be run, tested, and reviewed, and cannot be directly regarded as production-ready.
