Before

// String concatenation nightmare

import { z } from "zod";

const systemPrompt = 
  "You are a " + role + ". " +
  "Context: " + context + ". " +
  "Rules: " + rules.join(", ") + ". " +

// No type safety. No validation.
// Hard to maintain and debug.

// String concatenation nightmare

import { z } from "zod";

const systemPrompt = 
  "You are a " + role + ". " +
  "Context: " + context + ". " +
  "Rules: " + rules.join(", ") + ". " +

// No type safety. No validation.
// Hard to maintain and debug.
