AI Turned My 5-Line Memo into Specs and Software in 45 Minutes

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 the
