+/**
+ * OpenRouter SDK - Enhanced Tool Support Examples
+ *
+ * This file demonstrates the automatic tool execution feature.
+ * When you provide tools with `execute` functions, they are automatically:
+ * 1. Validated using Zod schemas
+ * 2. Executed when the model calls them
+ * 3. Results sent back to the model
+ * 4. Process repeats until no more tool calls (up to maxToolRounds)
+ *
+ * The API is simple: just call getResponse() with tools, and await the result.
+ * Tools are executed transparently before getMessage() or getText() returns!
+ *
+ * maxToolRounds can be:
+ * - A number: Maximum number of tool execution rounds (default: 5)
+ * - A function: (context: TurnContext) => boolean
+ *   - Return true to allow another turn
+ *   - Return false to stop execution
+ *   - Context includes: numberOfTurns, messageHistory, model/models
+ */
