Use classes for complex state management (state machines):

class Counter {
  count = $state(0);
  incrementor = $state(1);
  increment() {
    this.count += this.incrementor;
  }
  resetCount() {
    this.count = 0;
  }
  resetIncrementor() {
    this.incrementor = 1;
  }
}
export const counter = new Counter();

2. Paste the text below wherever the tool keeps standing instructions
   — usually called system prompt, instructions, or persona.
3. Save it so it applies to every run rather than a single message.
