## What it does

The skill acts as a copy chief to construct a "why this works" angle. It breaks down what customers tried earlier, why those attempts fell short, and what sets the current approach apart.

The output follows four sections: `Failed Method`, `New Mechanism`, `Mechanism Name`, and `Why It Works`. The generated name must stay simple, memorable, and distinctive. Because generic explanations undermine credibility, the instructions strictly forbid vague descriptions.
