GitHub's new Spec Kit is fundamentally changing how we code with AI. Instead of vibing and letting AI freestyle your code, it now forces you to write the spec first, then generates code from that.

This is actually genius for production work but kills the creative flow state most devs love. No more "just build it and see what happens" - you gotta think through the architecture upfront.

The shift: AI goes from code monkey to structured builder. Better outputs, less chaos, but also less room for happy accidents.

If you're shipping serious products, this is huge. If you're prototyping or exploring, it might slow you down.
