The article explains how PRD, design documents, and SPEC each answer distinct questions—what, why, and how—while outlining their constraints, typical structures, real‑world examples, when to use or skip them, and how they fit into a seamless development pipeline.
The article analyzes how AI‑assisted coding evolves from a personal productivity tool to a team‑wide engineering practice by introducing Harness Engineering, detailing four core capabilities, a four‑stage workflow, concrete results, and clear boundaries for real‑world H5 development.
Augment Code’s recent article argues that spec‑driven development fails because specifications become stale, misleading AI agents, and proposes a dynamic "Intent" workflow where humans and agents co‑maintain the spec, turning agents from mere executors into collaborators.
This article explains how Spec‑Driven Development (SDD) uses structured, machine‑readable specifications as the single source of truth, introduces the open‑source OpenSpec/OPSX workflow that turns those specs into actionable AI‑driven steps, and compares it with OpenAPI, BDD, and traditional RFC processes.
