What you need to know The 2026 problem is drift, not speed. Coding agents generate working-looking code in seconds. The failure mode that costs you a sprint is the agent confidently building the wrong thing, beautifully, because the intent was never written down. Spec-driven development makes the spec sovereign. SDD treats a structured specification as the primary artifact from which implementation is derived, verified and governed. The code becomes a derivative; the spec is the source of truth. A good spec defines six elements. Outcomes, scope boundaries, constraints, prior decisions, task breakdown and verification criteria. Leave any one out and the agent fills the gap with a plausible guess. You already do a version of this. A CLAUDE.md or AGENTS.md context file is the low-tech form…
