When I set out to build Willow for the Gemini Live Agent Challenge, I wanted to solve a structural problem: absolute subservience. I wanted to build an AI that felt like a peer — someone with boundaries, a memory, and the mathematical integrity to push back when a line is crossed. ## The Architecture of "Warm but Sharp" Willow isn't just a prompt-wrapped bot.
