Use when starting features, projects, or refactors with AI coding agents and requirements feel informal, incomplete, or drift-prone. Triggers: AI generates code that ignores constraints, same prompt produces different implementations across sessions, team lacks shared technical understanding, complex features need traceable design decisions, or vibe-coding produces unreliable output. Keywords: spec-driven, SDD, specification-first, requirements.md, plan.md, tasks.md, constitution.md, design doc, PRD, acceptance criteria, MoSCoW, drift detection, AI planning, feature spec, context drift, hallucination, constrained generation, boundaries, risks-identification, assumption-surface, living-document.
