First, take a look at this. 👉 Earthquake Map Built from a 5-line memo in 45 minutes. With a spec and tests. And my actual hands-on time was under 10 minutes . Spent the rest drinking beer. This is SDD meets Agentic SDLC. According to PwC's 2026 report , by 2027 more than half of all teams will develop this way. Terminology Agentic SDLC = A development style where AI agents autonomously execute the entire SDLC. Proposed by PwC, Microsoft, and others. Agentic = Given a goal, the AI keeps acting autonomously to achieve it. SDLC = Software Development Life Cycle (requirements → design → implementation → testing → operations). SDD = Spec-Driven Development. Covers only the design → implementation portion. Narrower scope than SDLC. PwC = PricewaterhouseCoopers (Big Four consultancy). Why? I wanted to test a simple question: can AI go from a vague idea to a production-quality app — with specs and tests — in under an hour? So I built an open-source framework called gr-sw-maker and put it to th
