Understanding Spec-Driven Development: Kiro, spec-kit, and Tessl

---

What I like here is that it makes the value of spec-driven development concrete instead of mystical. The tooling will keep changing, but the pattern is already familiar: agents produce better code when you give them intent, boundaries, and acceptance criteria up front. --- That is the same reason I keep leaning on architecture walkthroughs, issue context, and repo-local skills. The exact product names are less important than the discipline of giving the model a real brief before it starts typing.
