+# PraisonAI Tool Registration Examples
+
+This document demonstrates the three different ways to register tool functions in PraisonAI.
+
+## Method 1: Using the `tools` array with function objects directly
+
+```typescript
+import { Agent } from 'praisonai';
+
+// Define the functions directly
+async function getWeather(location: string) {
+  console.log(`Getting weather for ${location}...`);
+  return `${Math.floor(Math.random() * 30)}°C`;
+}
+
+async function getTime(location: string) {
+  console.log(`Getting time for ${location}...`);
+  const now = new Date();
+  return `${now.getHours()}:${now.getMinutes()}`;
+}
+
+// Create an agent with directly registered functions
+const agent = new Agent({ 
+  instructions: `You provide the current weather and time for requested locations.`,
+  name: "DirectFunctionAgent",
+  // Register functions directly as an array
+  tools: [getWeather, getTime]
+});
+
+// Start the agent with a prompt that will trigger tool usage
+agent.start("What's the weather and time in Paris, France?");
+```
+
+## Method 2: Using the `toolFunctions` object with name-function pairs
+
+```typescript
+import { Agent } from 'praisonai';
+
+// Define the functions directly
+async function getWeather(location: string) {
+  console.log(`Getting weather for ${location}...`);
+  return `${Math.floor(Math.random() * 30)}°C`;
+}
+
+async function getTime(location: string) {
+  console.log(`Getting time for ${location}...`);
+  const now = new Date();
+  return `${now.getHours()}:${now.getMinutes()}`;
+}
+
+// Create an agent with directly registered functions
+const agent = new Agent({ 
+  instructions: `You provide the current weather and time for requested locations.`,
+  name: "DirectFunctionAgent",
+  // Register functions with custom names
+  toolFunctions: {
+    get_weather: getWeather,
+    get_time: getTime
+  }
+});
+
+// Start the agent with a prompt that will trigger tool usage
+agent.start("What's the weather and time in Paris, France?");
+```
+
+## Method 3: Using the `tools` array with pre-defined tool definitions
+
+```typescript
+import { Agent } from 'praisonai';
+
+// Define the functions
+async function getWeather(location: string) {
+  console.log(`Getting weather for ${location}...`);
+  return `${Math.floor(Math.random() * 30)}°C`;
+}
+
+async function getTime(location: string) {
+  console.log(`Getting time for ${location}...`);
+  const now = new Date();
+  return `${now.getHours()}:${now.getMinutes()}`;
+}
+
+// Register functions globally
+import { registerFunction } from 'praisonai';
+registerFunction('get_weather', getWeather);
+registerFunction('get_time', getTime);
+
+// Define tool definitions
+const weatherTool = {
+  type: "function",
+  function: {
+    name: "get_weather",
+    description: "Get the current weather for a location",
+    parameters: {
+      type: "object",
+      properties: {
+        location: {
+          type: "string",
+          description: "The location to get weather for"
+        }
+      },
+      required: ["location"]
+    }
+  }
+};
+
+const timeTool = {
+  type: "function",
+  function: {
+    name: "get_time",
+    description: "Get the current time for a location",
+    parameters: {
+      type: "object",
+      properties: {
+        location: {
+          type: "string",
+          description: "The location to get time for"
+        }
+      },
+      required: ["location"]
+    }
+  }
+};
+
+// Create an agent with pre-defined tool definitions
+const agent = new Agent({ 
+  instructions: `You provide the current weather and time for requested locations.`,
+  name: "ToolDefinitionAgent",
+  // Register pre-defined tool definitions
+  tools: [weatherTool, timeTool]
+});
+
+// Start the agent with a prompt that will trigger tool usage
+agent.start("What's the weather and time in Paris, France?");
+```
+
+## Combined Approach
+
+You can also combine these approaches as needed:
+
+```typescript
+import { Agent } from 'praisonai';
+
+// Define the functions
+async function getWeather(location: string) {
+  console.log(`Getting weather for ${location}...`);
+  return `${Math.floor(Math.random() * 30)}°C`;
+}
+
+async function getTime(location: string) {
+  console.log(`Getting time for ${location}...`);
+  const now = new Date();
+  return `${now.getHours()}:${now.getMinutes()}`;
+}
+
+// Define a custom tool definition
+const calculatorTool = {
+  type: "function",
+  function: {
+    name: "calculate",
+    description: "Perform a calculation",
+    parameters: {
+      type: "object",
+      properties: {
+        expression: {
+          type: "string",
+          description: "The mathematical expression to calculate"
+        }
+      },
+      required: ["expression"]
+    }
+  }
+};
+
+// Register the calculator function globally
+import { registerFunction } from 'praisonai';
+registerFunction('calculate', async (expression: string) => {
+  console.log(`Calculating ${expression}...`);
+  // Simple eval for demonstration purposes only
+  return eval(expression).toString();
+});
+
+// Create an agent with mixed tool registration approaches
+const agent = new Agent({ 
+  instructions: `You can provide weather, time, and perform calculations.`,
+  name: "MixedToolAgent",
+  // Register functions directly as an array
+  tools: [getWeather, getTime, calculatorTool]
+});
+
+// Start the agent with a prompt that will trigger tool usage
+agent.start("What's the weather in Paris, the time in Tokyo, and what is 25 * 4?");
+```
