Spec-first Vs Spec-driven Development?
5.0BRAINROT SCORESPEC-FIRST— ORIGIN, MEANING & USAGE
Spec-First An engineering approach where writing the specification is treated as the primary act of software design, with code generation — whether by AI or by hand — following as a downstream, largely mechanical step.
EXAMPLE USAGE
"We're spec-first now, code review is basically just checking it matches the doc."
SPEC-DRIVEN DEVELOPMENT— ORIGIN, MEANING & USAGE
Spec-Driven Development A coding workflow where a detailed written specification is produced first and an AI agent implements against it, treating the spec rather than the prompt as the primary artifact steering the work.
EXAMPLE USAGE
"Switched to spec-driven development, the agent stopped making things up halfway through."
