Somebody already made this, and wrote down what it cost

The library has twenty-six genre templates and six worked examples, and the examples carry something almost nobody publishes: how many rerolls each pattern actually took before it produced a usable clip. Two or three attempts at the low end and twenty-plus at the high end, for the same shot. That variance is the budget, and knowing it before you start is worth more than any amount of prompt polish.

The matcher is free and needs no account. Describe the idea and the whole library ranks itself in your browser, with the arithmetic showing — which tags matched, what each was worth, and what the nearest recorded pattern cost. Then the seven hard rules run on whatever you write. Every lane also ships a worked example that costs nothing. Writing a prompt needs credits.
