+### Using Crews and Flows Together
+
+CrewAI's power truly shines when combining Crews with Flows to create sophisticated automation pipelines. Here's how you can orchestrate multiple Crews within a Flow:
+
+```python
+from crewai.flow.flow import Flow, listen, start, router
+from crewai import Crew, Agent, Task
+from pydantic import BaseModel
+
+# Define structured state for precise control
+class MarketState(BaseModel):
+    sentiment: str = "neutral"
+    confidence: float = 0.0
+    recommendations: list = []
+
+class AdvancedAnalysisFlow(Flow[MarketState]):
+    @start()
+    def fetch_market_data(self):
+        # Demonstrate low-level control with structured state
+        self.state.sentiment = "analyzing"
+        return {"sector": "tech", "timeframe": "1W"}  # These parameters match the task description template
+
+    @listen(fetch_market_data)
+    def analyze_with_crew(self, market_data):
+        # Show crew agency through specialized roles
+        analyst = Agent(
+            role="Senior Market Analyst",
+            goal="Conduct deep market analysis with expert insight",
+            backstory="You're a veteran analyst known for identifying subtle market patterns"
+        )
+        researcher = Agent(
+            role="Data Researcher",
+            goal="Gather and validate supporting market data",

+        # Show flow control with conditional routing
+        if self.state.confidence > 0.8:
+            return "high_confidence"
+        elif self.state.confidence > 0.5:
+            return "medium_confidence"
+        return "low_confidence"
+
+    @listen("high_confidence")
+    def execute_strategy(self):
+        # Demonstrate complex decision making
+        strategy_crew = Crew(
+            agents=[
+                Agent(role="Strategy Expert",
+                      goal="Develop optimal market strategy")
+            ],
+            tasks=[
+                Task(description="Create detailed strategy based on analysis",
+                     expected_output="Step-by-step action plan")
+            ]
+        )
+        return strategy_crew.kickoff()

+    def request_additional_analysis(self):
+        self.state.recommendations.append("Gather more data")
+        return "Additional analysis required"
+```
+
+This example demonstrates how to:
+1. Use Python code for basic data operations
+2. Create and execute Crews as steps in your workflow
+3. Use Flow decorators to manage the sequence of operations
+4. Implement conditional branching based on Crew results

 ## Connecting Your Crew to a Model
 
 CrewAI supports using various LLMs through a variety of connection options. By default your agents will use the OpenAI API when querying the model. However, there are several other ways to allow your agents to connect to models. For example, you can configure your agents to use a local model via the Ollama tool.

 ## How CrewAI Compares
 
-**CrewAI's Advantage**: CrewAI is built with production in mind. It offers the flexibility of Autogen's conversational agents and the structured process approach of ChatDev, but without the rigidity. CrewAI's processes are designed to be dynamic and adaptable, fitting seamlessly into both development and production workflows.
+**CrewAI's Advantage**: CrewAI combines autonomous agent intelligence with precise workflow control through its unique Crews and Flows architecture. The framework excels at both high-level orchestration and low-level customization, enabling complex, production-grade systems with granular control.
 
-- **Autogen**: While Autogen does good in creating conversational agents capable of working together, it lacks an inherent concept of process. In Autogen, orchestrating agents' interactions requires additional programming, which can become complex and cumbersome as the scale of tasks grows.
+- **LangGraph**: While LangGraph provides a foundation for building agent workflows, its approach requires significant boilerplate code and complex state management patterns. The framework's tight coupling with LangChain can limit flexibility when implementing custom agent behaviors or integrating with external systems.
+
+*P.S. CrewAI demonstrates significant performance advantages over LangGraph, executing 5.76x faster in certain cases like this QA task example ([see comparison](https://github.com/crewAIInc/crewAI-examples/tree/main/Notebooks/CrewAI%20Flows%20%26%20Langgraph/QA%20Agent)) while achieving higher evaluation scores with faster completion times in certain coding tasks, like in this example ([detailed analysis](https://github.com/crewAIInc/crewAI-examples/blob/main/Notebooks/CrewAI%20Flows%20%26%20Langgraph/Coding%20Assistant/coding_assistant_eval.ipynb)).*
+
+- **Autogen**: While Autogen excels at creating conversational agents capable of working together, it lacks an inherent concept of process. In Autogen, orchestrating agents' interactions requires additional programming, which can become complex and cumbersome as the scale of tasks grows.
 
 - **ChatDev**: ChatDev introduced the idea of processes into the realm of AI agents, but its implementation is quite rigid. Customizations in ChatDev are limited and not geared towards production environments, which can hinder scalability and flexibility in real-world applications.

+## Task Guardrails
+
+Task guardrails provide a way to validate and transform task outputs before they
+are passed to the next task. This feature helps ensure data quality and provides
+efeedback to agents when their output doesn't meet specific criteria.
+
+### Using Task Guardrails
+
+To add a guardrail to a task, provide a validation function through the `guardrail` parameter:
+
+```python Code
+from typing import Tuple, Union, Dict, Any
+
+def validate_blog_content(result: str) -> Tuple[bool, Union[Dict[str, Any], str]]:
+    """Validate blog content meets requirements."""
+    try:
+        # Check word count
+        word_count = len(result.split())
+        if word_count > 200:
+            return (False, {
+                "error": "Blog content exceeds 200 words",
+                "code": "WORD_COUNT_ERROR",
+                "context": {"word_count": word_count}
+            })
+
+        # Additional validation logic here
+        return (True, result.strip())
+    except Exception as e:
+        return (False, {
+            "error": "Unexpected error during validation",
+            "code": "SYSTEM_ERROR"
+        })
+
+blog_task = Task(
+    description="Write a blog post about AI",
+    expected_output="A blog post under 200 words",
+    agent=blog_agent,
+    guardrail=validate_blog_content  # Add the guardrail function
+)
+```
+
+### Guardrail Function Requirements
+
+1. **Function Signature**:
+   - Must accept exactly one parameter (the task output)
+   - Should return a tuple of `(bool, Any)`
+   - Type hints are recommended but optional
+
+2. **Return Values**:
+   - Success: Return `(True, validated_result)`
+   - Failure: Return `(False, error_details)`
+
+### Error Handling Best Practices
+
+1. **Structured Error Responses**:
+```python Code
+def validate_with_context(result: str) -> Tuple[bool, Union[Dict[str, Any], str]]:
+    try:
+        # Main validation logic
+        validated_data = perform_validation(result)
+        return (True, validated_data)
+    except ValidationError as e:
+        return (False, {
+            "error": str(e),
+            "code": "VALIDATION_ERROR",
+            "context": {"input": result}
+        })
+    except Exception as e:
+        return (False, {
+            "error": "Unexpected error",
+            "code": "SYSTEM_ERROR"
+        })
+```
+
+2. **Error Categories**:
+   - Use specific error codes
+   - Include relevant context
+   - Provide actionable feedback
+
+3. **Validation Chain**:
+```python Code
+from typing import Any, Dict, List, Tuple, Union
+
+def complex_validation(result: str) -> Tuple[bool, Union[str, Dict[str, Any]]]:
+    """Chain multiple validation steps."""
+    # Step 1: Basic validation
+    if not result:

+            "context": {"step": "content_validation"}
+        })
+```
+
+### Handling Guardrail Results
+
+When a guardrail returns `(False, error)`:
+1. The error is sent back to the agent
+2. The agent attempts to fix the issue
+3. The process repeats until:
+   - The guardrail returns `(True, result)`
+   - Maximum retries are reached
+
+Example with retry handling:
+```python Code
+from typing import Optional, Tuple, Union
+
+def validate_json_output(result: str) -> Tuple[bool, Union[Dict[str, Any], str]]:
+    """Validate and parse JSON output."""
+    try:
+        # Try to parse as JSON
+        data = json.loads(result)
+        return (True, data)
+    except json.JSONDecodeError as e:
+        return (False, {
+            "error": "Invalid JSON format",
+            "code": "JSON_ERROR",
+            "context": {"line": e.lineno, "column": e.colno}
+        })
+
+task = Task(
+    description="Generate a JSON report",
+    expected_output="A valid JSON object",
+    agent=analyst,
+    guardrail=validate_json_output,
+    max_retries=3  # Limit retry attempts
+)
+```
+
 ## Getting Structured Consistent Outputs from Tasks
-When you need to ensure that a task outputs a structured and consistent format, you can use the `output_pydantic` or `output_json` properties on a task. These properties allow you to define the expected output structure, making it easier to parse and utilize the results in your application. 
 
 <Note>
 It's also important to note that the output of the final task of a crew becomes the final output of the actual crew itself.

 These validations help in maintaining the consistency and reliability of task executions within the crewAI framework.
 
+## Task Guardrails
+
+Task guardrails provide a powerful way to validate, transform, or filter task outputs before they are passed to the next task. Guardrails are optional functions that execute before the next task starts, allowing you to ensure that task outputs meet specific requirements or formats.
+
+### Basic Usage
+
+```python Code
+from typing import Tuple, Union
+from crewai import Task
+
+def validate_json_output(result: str) -> Tuple[bool, Union[dict, str]]:
+    """Validate that the output is valid JSON."""
+    try:
+        json_data = json.loads(result)
+        return (True, json_data)
+    except json.JSONDecodeError:
+        return (False, "Output must be valid JSON")
+
+task = Task(
+    description="Generate JSON data",
+    expected_output="Valid JSON object",
+    guardrail=validate_json_output
+)
+```
+
+### How Guardrails Work
+
+1. **Optional Attribute**: Guardrails are an optional attribute at the task level, allowing you to add validation only where needed.
+2. **Execution Timing**: The guardrail function is executed before the next task starts, ensuring valid data flow between tasks.
+3. **Return Format**: Guardrails must return a tuple of `(success, data)`:
+   - If `success` is `True`, `data` is the validated/transformed result
+   - If `success` is `False`, `data` is the error message
+4. **Result Routing**:
+   - On success (`True`), the result is automatically passed to the next task
+   - On failure (`False`), the error is sent back to the agent to generate a new answer
+
+### Common Use Cases
+
+#### Data Format Validation
+```python Code
+def validate_email_format(result: str) -> Tuple[bool, Union[str, str]]:
+    """Ensure the output contains a valid email address."""
+    import re
+    email_pattern = r'^[\w\.-]+@[\w\.-]+\.\w+$'
+    if re.match(email_pattern, result.strip()):
+        return (True, result.strip())
+    return (False, "Output must be a valid email address")
+```
+
+#### Content Filtering
+```python Code
+def filter_sensitive_info(result: str) -> Tuple[bool, Union[str, str]]:
+    """Remove or validate sensitive information."""
+    sensitive_patterns = ['SSN:', 'password:', 'secret:']
+    for pattern in sensitive_patterns:
+        if pattern.lower() in result.lower():
+            return (False, f"Output contains sensitive information ({pattern})")
+    return (True, result)
+```
+
+#### Data Transformation
+```python Code
+def normalize_phone_number(result: str) -> Tuple[bool, Union[str, str]]:
+    """Ensure phone numbers are in a consistent format."""
+    import re
+    digits = re.sub(r'\D', '', result)
+    if len(digits) == 10:
+        formatted = f"({digits[:3]}) {digits[3:6]}-{digits[6:]}"
+        return (True, formatted)
+    return (False, "Output must be a 10-digit phone number")
+```
+
+### Advanced Features
+
+#### Chaining Multiple Validations
+```python Code
+def chain_validations(*validators):
+    """Chain multiple validators together."""
+    def combined_validator(result):
+        for validator in validators:
+            success, data = validator(result)
+            if not success:
+                return (False, data)
+            result = data
+        return (True, result)
+    return combined_validator
+
+# Usage
+task = Task(
+    description="Get user contact info",
+    expected_output="Email and phone",
+    guardrail=chain_validations(
+        validate_email_format,
+        filter_sensitive_info
+    )
+)
+```

+title: Using Multimodal Agents
+description: Learn how to enable and use multimodal capabilities in your agents for processing images and other non-text content within the CrewAI framework.
+icon: image
+---
+
+# Using Multimodal Agents
+
+CrewAI supports multimodal agents that can process both text and non-text content like images. This guide will show you how to enable and use multimodal capabilities in your agents.
+
+## Enabling Multimodal Capabilities
+
+To create a multimodal agent, simply set the `multimodal` parameter to `True` when initializing your agent:
+
+```python
+from crewai import Agent
+
+agent = Agent(
+    role="Image Analyst",
+    goal="Analyze and extract insights from images",
+    backstory="An expert in visual content interpretation with years of experience in image analysis",
+    multimodal=True  # This enables multimodal capabilities
+)
+```
+
+When you set `multimodal=True`, the agent is automatically configured with the necessary tools for handling non-text content, including the `AddImageTool`.
+
+## Working with Images
+
+The multimodal agent comes pre-configured with the `AddImageTool`, which allows it to process images. You don't need to manually add this tool - it's automatically included when you enable multimodal capabilities.
+
+Here's a complete example showing how to use a multimodal agent to analyze an image:
+
+```python
+from crewai import Agent, Task, Crew
+
+# Create a multimodal agent
+image_analyst = Agent(
+    role="Product Analyst",
+    goal="Analyze product images and provide detailed descriptions",
+    backstory="Expert in visual product analysis with deep knowledge of design and features",
+    multimodal=True
+)
+
+# Create a task for image analysis
+task = Task(
+    description="Analyze the product image at https://example.com/product.jpg and provide a detailed description",
+    agent=image_analyst
+)
+
+# Create and run the crew
+crew = Crew(
+    agents=[image_analyst],
+    tasks=[task]
+)
+
+result = crew.kickoff()
+```
+
+### Advanced Usage with Context
+
+You can provide additional context or specific questions about the image when creating tasks for multimodal agents. The task description can include specific aspects you want the agent to focus on:
+
+```python
+from crewai import Agent, Task, Crew
+
+# Create a multimodal agent for detailed analysis
+expert_analyst = Agent(
+    role="Visual Quality Inspector",
+    goal="Perform detailed quality analysis of product images",
+    backstory="Senior quality control expert with expertise in visual inspection",
+    multimodal=True  # AddImageTool is automatically included
+)
+
+# Create a task with specific analysis requirements
+inspection_task = Task(
+    description="""
+    Analyze the product image at https://example.com/product.jpg with focus on:
+    1. Quality of materials
+    2. Manufacturing defects
+    3. Compliance with standards
+    Provide a detailed report highlighting any issues found.
+    """,
+    agent=expert_analyst
+)
+
+# Create and run the crew
+crew = Crew(
+    agents=[expert_analyst],
+    tasks=[inspection_task]
+)
+
+result = crew.kickoff()
+```
+
+### Tool Details
+
+When working with multimodal agents, the `AddImageTool` is automatically configured with the following schema:
+
+```python
+class AddImageToolSchema:
+    image_url: str  # Required: The URL or path of the image to process
+    action: Optional[str] = None  # Optional: Additional context or specific questions about the image
+```
+
+The multimodal agent will automatically handle the image processing through its built-in tools, allowing it to:
+- Access images via URLs or local file paths
+- Process image content with optional context or specific questions
+- Provide analysis and insights based on the visual information and task requirements
+
+## Best Practices
+
+When working with multimodal agents, keep these best practices in mind:
+
+1. **Image Access**
+   - Ensure your images are accessible via URLs that the agent can reach
+   - For local images, consider hosting them temporarily or using absolute file paths
+   - Verify that image URLs are valid and accessible before running tasks
+
+2. **Task Description**
+   - Be specific about what aspects of the image you want the agent to analyze
+   - Include clear questions or requirements in the task description
+   - Consider using the optional `action` parameter for focused analysis
+
+3. **Resource Management**
+   - Image processing may require more computational resources than text-only tasks
+   - Some language models may require base64 encoding for image data
+   - Consider batch processing for multiple images to optimize performance
+
+4. **Environment Setup**
+   - Verify that your environment has the necessary dependencies for image processing
+   - Ensure your language model supports multimodal capabilities
+   - Test with small images first to validate your setup
+
+5. **Error Handling**
+   - Implement proper error handling for image loading failures
+   - Have fallback strategies for when image processing fails
+   - Monitor and log image processing operations for debugging

+description: A semantic search tool for code documentation websites using RAG capabilities
+icon: book-open
+---
+
+## CodeDocsSearchTool
+
+The CodeDocsSearchTool is a specialized Retrieval-Augmented Generation (RAG) tool that enables semantic search within code documentation websites. It inherits from the base RagTool class and provides both fixed and dynamic documentation URL searching capabilities.
+
+## Installation
+
+```bash
+pip install 'crewai[tools]'
+```
+
+## Usage Example
+
+```python
+from crewai import Agent
+from crewai_tools import CodeDocsSearchTool
+
+# Method 1: Dynamic documentation URL
+docs_search = CodeDocsSearchTool()
+
+# Method 2: Fixed documentation URL
+fixed_docs_search = CodeDocsSearchTool(
+    docs_url="https://docs.example.com"
+)
+
+# Create an agent with the tool
+researcher = Agent(
+    role='Documentation Researcher',
+    goal='Search through code documentation semantically',
+    backstory='Expert at finding relevant information in technical documentation.',
+    tools=[docs_search],
+    verbose=True
+)
+```
+
+## Input Schema
+
+The tool supports two input schemas depending on initialization:
+
+### Dynamic URL Schema
+```python
+class CodeDocsSearchToolSchema(BaseModel):
+    search_query: str  # The semantic search query
+    docs_url: str     # URL of the documentation site to search
+```
+
+### Fixed URL Schema
+```python
+class FixedCodeDocsSearchToolSchema(BaseModel):
+    search_query: str  # The semantic search query
+```
+
+## Function Signature
+
+```python
+def __init__(self, docs_url: Optional[str] = None, **kwargs):
+    """
+    Initialize the documentation search tool.
+
+    Args:
+        docs_url (Optional[str]): Fixed URL to a documentation site. If provided, 
+            the tool will only search this documentation.
+        **kwargs: Additional arguments passed to the parent RagTool
+    """
+
+def _run(self, search_query: str, **kwargs: Any) -> Any:
+    """
+    Perform semantic search on the documentation site.
+
+    Args:
+        search_query (str): The semantic search query
+        **kwargs: Additional arguments (including 'docs_url' for dynamic mode)
+
+    Returns:
+        str: Relevant documentation passages based on semantic search
+    """
+```
+
+## Best Practices
+
+1. Choose initialization method based on use case:
+   - Use fixed URL when repeatedly searching the same documentation
+   - Use dynamic URL when searching different documentation sites
+2. Write clear, semantic search queries
+3. Ensure documentation sites are accessible
+4. Consider documentation structure and size
+5. Handle potential URL access errors in agent prompts
+
+## Integration Example
+
+```python
+from crewai import Agent, Task, Crew
+from crewai_tools import CodeDocsSearchTool
+
+# Example 1: Fixed documentation search
+api_docs_search = CodeDocsSearchTool(
+    docs_url="https://api.example.com/docs"
+)
+
+# Example 2: Dynamic documentation search
+flexible_docs_search = CodeDocsSearchTool()
+
+# Create agents
+api_analyst = Agent(
+    role='API Documentation Analyst',
+    goal='Find relevant API endpoints and usage examples',
+    backstory='Expert at analyzing API documentation.',
+    tools=[api_docs_search]
+)
+
+docs_researcher = Agent(
+    role='Documentation Researcher',
+    goal='Search through various documentation sites',
+    backstory='Specialist in finding information across multiple docs.',
+    tools=[flexible_docs_search]
+)
+
+# Define tasks
+fixed_search_task = Task(
+    description="""Find all authentication-related endpoints 
+    in the API documentation.""",
+    agent=api_analyst
+)
+
+# The agent will use:
+# {
+#   "search_query": "authentication endpoints and methods"
+# }
+
+dynamic_search_task = Task(
+    description="""Search through the Python documentation at 
+    docs.python.org for information about async/await.""",
+    agent=docs_researcher
+)
+
+# The agent will use:
+# {
+#   "search_query": "async await syntax and usage",
+#   "docs_url": "https://docs.python.org"
+# }
+
+# Create crew
+crew = Crew(
+    agents=[api_analyst, docs_researcher],
+    tasks=[fixed_search_task, dynamic_search_task]
+)
+
+# Execute
+result = crew.kickoff()
+```

+title: Directory Read Tool
+description: A tool for recursively listing directory contents
+---
+
+# Directory Read Tool
+
+The Directory Read Tool provides functionality to recursively list all files within a directory. It supports both fixed and dynamic directory path modes, allowing you to specify the directory at initialization or runtime.
+
+## Installation
+
+```bash
+pip install 'crewai[tools]'
+```
+
+## Usage
+
+You can use the Directory Read Tool in two ways:
+
+### 1. Fixed Directory Path
+
+Initialize the tool with a specific directory path:
+
+```python
+from crewai import Agent
+from crewai_tools import DirectoryReadTool
+
+# Initialize with a fixed directory
+tool = DirectoryReadTool(directory="/path/to/your/directory")
+
+# Create an agent with the tool
+agent = Agent(
+    role='File System Analyst',
+    goal='Analyze directory contents',
+    backstory='I help analyze and organize file systems',
+    tools=[tool]
+)
+
+# Use in a task
+task = Task(
+    description="List all files in the project directory",
+    agent=agent
+)
+```
+
+### 2. Dynamic Directory Path
+
+Initialize the tool without a specific directory path to provide it at runtime:
+
+```python
+from crewai import Agent
+from crewai_tools import DirectoryReadTool
+
+# Initialize without a fixed directory
+tool = DirectoryReadTool()
+
+# Create an agent with the tool
+agent = Agent(
+    role='File System Explorer',
+    goal='Explore different directories',
+    backstory='I analyze various directory structures',
+    tools=[tool]
+)
+
+# Use in a task with dynamic directory path
+task = Task(
+    description="List all files in the specified directory",
+    agent=agent,
+    context={
+        "directory": "/path/to/explore"
+    }
+)
+```
+
+## Input Schema
+
+### Fixed Directory Mode
+```python
+class FixedDirectoryReadToolSchema(BaseModel):
+    pass  # No additional parameters needed when directory is fixed
+```
+
+### Dynamic Directory Mode
+```python
+class DirectoryReadToolSchema(BaseModel):
+    directory: str  # The path to the directory to list contents
+```
+
+## Function Signatures
+
+```python
+def __init__(self, directory: Optional[str] = None, **kwargs):
+    """
+    Initialize the Directory Read Tool.
+    
+    Args:
+        directory (Optional[str]): Path to the directory (optional)
+        **kwargs: Additional arguments passed to BaseTool
+    """
+
+def _run(
+    self,
+    **kwargs: Any,
+) -> str:
+    """
+    Execute the directory listing.
+    
+    Args:
+        **kwargs: Arguments including 'directory' for dynamic mode
+    
+    Returns:
+        str: A formatted string containing all file paths in the directory
+    """
+```
+
+## Best Practices
+
+1. **Path Handling**:
+   - Use absolute paths to avoid path resolution issues
+   - Handle trailing slashes appropriately
+   - Verify directory existence before listing
+
+2. **Performance Considerations**:
+   - Be mindful of directory size when listing large directories
+   - Consider implementing pagination for large directories
+   - Handle symlinks appropriately
+
+3. **Error Handling**:
+   - Handle directory not found errors gracefully
+   - Manage permission issues appropriately
+   - Validate input parameters before processing
+
+## Example Integration
+
+Here's a complete example showing how to integrate the Directory Read Tool with CrewAI:
+
+```python
+from crewai import Agent, Task, Crew
+from crewai_tools import DirectoryReadTool
+
+# Initialize the tool
+dir_tool = DirectoryReadTool()
+
+# Create an agent with the tool
+file_analyst = Agent(
+    role='File System Analyst',
+    goal='Analyze and report on directory structures',
+    backstory='I am an expert at analyzing file system organization',
+    tools=[dir_tool]
+)
+
+# Create tasks
+analysis_task = Task(
+    description="""
+    Analyze the project directory structure:
+    1. List all files recursively
+    2. Identify key file types
+    3. Report on directory organization
+    
+    Provide a comprehensive analysis of the findings.
+    """,
+    agent=file_analyst,
+    context={
+        "directory": "/path/to/project"
+    }
+)
+
+# Create and run the crew
+crew = Crew(
+    agents=[file_analyst],
+    tasks=[analysis_task]
+)
+
+result = crew.kickoff()
+```
+
+## Error Handling
+
+The tool handles various error scenarios:
+
+1. **Directory Not Found**:
+   ```python
+   try:
+       tool = DirectoryReadTool(directory="/nonexistent/path")
+   except FileNotFoundError:
+       print("Directory not found. Please verify the path.")
+   ```
+
+2. **Permission Issues**:
+   ```python
+   try:
+       tool = DirectoryReadTool(directory="/restricted/path")
+   except PermissionError:
+       print("Insufficient permissions to access the directory.")
+   ```
+
+3. **Invalid Path**:
+   ```python
+   try:
+       result = tool._run(directory="invalid/path")
+   except ValueError:
+       print("Invalid directory path provided.")
+   ```
+
+## Output Format
+
+The tool returns a formatted string containing all file paths in the directory:
+
+```
+File paths:
+- /path/to/directory/file1.txt
+- /path/to/directory/subdirectory/file2.txt
+- /path/to/directory/subdirectory/file3.py
+```
+
+
+Each file path is listed on a new line with a hyphen prefix, making it easy to parse and read the output.

+
+# Create crew
+crew = Crew(
+    agents=[web_analyst],
+    tasks=[crawl_task]
+)
+
+# Execute
+result = crew.kickoff()
+```
+
+## Configuration Options
+
+### URL Parameters

+title: MDX Search Tool
+description: A tool for semantic searching within MDX files using RAG capabilities
+---
+
+# MDX Search Tool
+
+The MDX Search Tool enables semantic searching within MDX (Markdown with JSX) files using Retrieval-Augmented Generation (RAG) capabilities. It supports both fixed and dynamic file path modes, allowing you to specify the MDX file at initialization or runtime.
+
+## Installation
+
+```bash
+pip install 'crewai[tools]'
+```
+
+## Usage
+
+You can use the MDX Search Tool in two ways:
+
+### 1. Fixed MDX File Path
+
+Initialize the tool with a specific MDX file path:
+
+```python
+from crewai import Agent
+from crewai_tools import MDXSearchTool
+
+# Initialize with a fixed MDX file
+tool = MDXSearchTool(mdx="/path/to/your/document.mdx")
+
+# Create an agent with the tool
+agent = Agent(
+    role='Technical Writer',
+    goal='Search through MDX documentation',
+    backstory='I help find relevant information in MDX documentation',
+    tools=[tool]
+)
+
+# Use in a task
+task = Task(
+    description="Find information about API endpoints in the documentation",
+    agent=agent
+)
+```
+
+### 2. Dynamic MDX File Path
+
+Initialize the tool without a specific file path to provide it at runtime:
+
+```python
+from crewai import Agent
+from crewai_tools import MDXSearchTool
+
+# Initialize without a fixed MDX file
+tool = MDXSearchTool()
+
+# Create an agent with the tool
+agent = Agent(
+    role='Documentation Analyst',
+    goal='Search through various MDX files',
+    backstory='I analyze different MDX documentation files',
+    tools=[tool]
+)
+
+# Use in a task with dynamic file path
+task = Task(
+    description="Search for 'authentication' in the API documentation",
+    agent=agent,
+    context={
+        "mdx": "/path/to/api-docs.mdx",
+        "search_query": "authentication"
+    }
+)
+```
+
+## Input Schema
+
+### Fixed MDX File Mode
+```python
+class FixedMDXSearchToolSchema(BaseModel):
+    search_query: str  # The search query to find content in the MDX file
+```
+
+### Dynamic MDX File Mode
+```python
+class MDXSearchToolSchema(BaseModel):
+    search_query: str  # The search query to find content in the MDX file
+    mdx: str  # The path to the MDX file to search
+```
+
+## Function Signatures
+
+```python
+def __init__(self, mdx: Optional[str] = None, **kwargs):
+    """
+    Initialize the MDX Search Tool.
+    
+    Args:
+        mdx (Optional[str]): Path to the MDX file (optional)
+        **kwargs: Additional arguments passed to RagTool
+    """
+
+def _run(
+    self,
+    search_query: str,
+    **kwargs: Any,
+) -> str:
+    """
+    Execute the search on the MDX file.
+    
+    Args:
+        search_query (str): The query to search for
+        **kwargs: Additional arguments including 'mdx' for dynamic mode
+    
+    Returns:
+        str: The search results from the MDX content
+    """
+```
+
+## Best Practices
+
+1. **File Path Handling**:
+   - Use absolute paths to avoid path resolution issues
+   - Verify file existence before searching
+   - Handle file permissions appropriately
+
+2. **Query Optimization**:
+   - Use specific, focused search queries
+   - Consider context when formulating queries
+   - Break down complex searches into smaller queries
+
+3. **Error Handling**:
+   - Handle file not found errors gracefully
+   - Manage permission issues appropriately
+   - Validate input parameters before processing
+
+## Example Integration
+
+Here's a complete example showing how to integrate the MDX Search Tool with CrewAI:
+
+```python
+from crewai import Agent, Task, Crew
+from crewai_tools import MDXSearchTool
+
+# Initialize the tool
+mdx_tool = MDXSearchTool()
+
+# Create an agent with the tool
+researcher = Agent(
+    role='Documentation Researcher',
+    goal='Find and analyze information in MDX documentation',
+    backstory='I am an expert at finding relevant information in documentation',
+    tools=[mdx_tool]
+)
+
+# Create tasks
+search_task = Task(
+    description="""
+    Search through the API documentation for information about authentication methods.
+    Look for:
+    1. Authentication endpoints
+    2. Security best practices
+    3. Token handling
+    
+    Provide a comprehensive summary of the findings.
+    """,
+    agent=researcher,
+    context={
+        "mdx": "/path/to/api-docs.mdx",
+        "search_query": "authentication security tokens"
+    }
+)
+
+# Create and run the crew
+crew = Crew(
+    agents=[researcher],
+    tasks=[search_task]
+)
+
+result = crew.kickoff()
+```
+
+## Error Handling
+
+The tool handles various error scenarios:
+
+1. **File Not Found**:
+   ```python
+   try:
+       tool = MDXSearchTool(mdx="/path/to/nonexistent.mdx")
+   except FileNotFoundError:
+       print("MDX file not found. Please verify the file path.")
+   ```
+
+2. **Permission Issues**:
+   ```python
+   try: 
+       tool = MDXSearchTool(mdx="/restricted/docs.mdx")
+   except PermissionError:
+       print("Insufficient permissions to access the MDX file.")
+   ```
+
+3. **Invalid Content**:
+   ```python
+   try:
+       result = tool._run(search_query="query", mdx="/path/to/invalid.mdx")
+   except ValueError:
+       print("Invalid MDX content or format.")
+   ```

+
+# Initialize the tool with database configuration
+search_tool = PGSearchTool(
+    db_uri="postgresql://user:password@localhost:5432/dbname",
+    table_name="your_table"
+)
+
+# Create an agent with the tool
+researcher = Agent(
+    role='Database Researcher',
+    goal='Find relevant information in database content',
+    backstory='Expert at searching and analyzing database content.',
+    tools=[search_tool],
+    verbose=True
+)
+```
+
+## Input Schema
+
+```python
+class PGSearchToolSchema(BaseModel):

+)
+
+# Create agent
+analyst = Agent(
+    role='Database Analyst',
+    goal='Analyze customer feedback data',
+    backstory='Expert at finding insights in customer feedback.',
+    tools=[db_search]
+)
+
+# Define task
+analysis_task = Task(
+    description="""Find all customer feedback related to product usability
+    and ease of use. Focus on common patterns and issues.""",
+    agent=analyst
+)
+
+# The tool will use:
+# {
+#   "search_query": "product usability feedback ease of use issues"
+# }
+
+# Create crew
+crew = Crew(
+    agents=[analyst],
+    tasks=[analysis_task]
+)
+
+# Execute
+result = crew.kickoff()
+```
+
+## Advanced Usage
+
+### Multiple Table Search
+```python
+# Create tools for different tables
+customer_search = PGSearchTool(
+    db_uri="postgresql://user:password@localhost:5432/dbname",
+    table_name="customers"
+)
+
+orders_search = PGSearchTool(
+    db_uri="postgresql://user:password@localhost:5432/dbname",
+    table_name="orders"
+)
+
+# Use both tools in an agent
+analyst = Agent(
+    role='Multi-table Analyst',
+    goal='Analyze customer and order data',
+    tools=[customer_search, orders_search]
+)
+```
+
+### Error Handling

+
+1. **API Key Management**:
+   - Store the API key securely in environment variables
+   - Never hardcode the API key in your code
+   - Verify API key validity before making requests
+
+2. **Search Optimization**:
+   - Use specific, targeted search queries
+   - Include relevant keywords and time frames
+   - Leverage location parameter for regional results
+
+3. **Error Handling**:
+   - Handle API rate limits gracefully
+   - Implement retry logic for failed requests
+   - Validate input parameters before making requests
+
+## Example Integration
+
+Here's a complete example showing how to integrate the SerpApi Google Search Tool with CrewAI:
+
+```python
+from crewai import Agent, Task, Crew
+from crewai_tools import SerpApiGoogleSearchTool
+
+# Initialize the tool
+search_tool = SerpApiGoogleSearchTool()
+
+# Create an agent with the tool
+researcher = Agent(
+    role='Research Analyst',
+    goal='Find and analyze current information',
+    backstory="""I am an expert at finding and analyzing 
+    information from various online sources.""",
+    tools=[search_tool]
+)
+
+# Create tasks
+research_task = Task(
+    description="""
+    Research the following topic:
+    1. Latest developments in quantum computing
+    2. Focus on practical applications
+    3. Include major company announcements
+    
+    Provide a comprehensive analysis of the findings.

+
+# Create and run the crew
+crew = Crew(
+    agents=[researcher],
+    tasks=[research_task]
+)
+
+result = crew.kickoff()
+```
+
+## Error Handling
+
+The tool handles various error scenarios:
+
+1. **Missing API Key**:
+   ```python
+   try:
+       tool = SerpApiGoogleSearchTool()
+   except ValueError as e:
+       print("API key not found. Set SERPAPI_API_KEY environment variable.")
+   ```

+   ```python
+   try:
+       results = tool._run(
+           search_query="quantum computing",
+           location="United States"
+       )
+   except HTTPError as e:
+       print(f"API request failed: {str(e)}")
+   ```
+
+3. **Invalid Parameters**:
+   ```python
+   try:
+       results = tool._run(
+           search_query="",  # Empty query
+           location="Invalid Location"
+       )
+   except ValueError as e:
+       print("Invalid search parameters provided.")
+   ```
+
+## Response Format
+
+The tool returns a filtered dictionary containing Google search results. Example response structure:
+
+```python
+{
+    "organic_results": [
+        {
+            "title": "Page Title",
+            "link": "https://...",
+            "snippet": "Page description or excerpt...",
+            "position": 1
+        }
+        # Additional results...
+    ],
+    "knowledge_graph": {
+        "title": "Topic Title",
+        "description": "Topic description...",
+        "source": {
+            "name": "Source Name",
+            "link": "https://..."
+        }

+            "answer": "Answer to related question..."
+        }
+        # Additional related questions...
+    ]
+}
+```
+
+The response is automatically filtered to remove metadata and unnecessary fields, focusing on the most relevant search information. Fields like search metadata, parameters, and pagination are omitted for clarity.

+## TXTSearchTool
+
+The TXTSearchTool is a specialized Retrieval-Augmented Generation (RAG) tool that enables semantic search within text files. It inherits from the base RagTool class and provides both fixed and dynamic text file searching capabilities.
+
+## Installation
+
+```bash
+pip install 'crewai[tools]'
+```
+
+## Usage Example
+
+```python
+from crewai import Agent
+from crewai_tools import TXTSearchTool
+
+# Method 1: Dynamic file path
+txt_search = TXTSearchTool()
+
+# Method 2: Fixed file path
+fixed_txt_search = TXTSearchTool(txt="path/to/fixed/document.txt")
+
+# Create an agent with the tool
+researcher = Agent(

+    goal='Search through text documents semantically',
+    backstory='Expert at finding relevant information in documents using semantic search.',
+    tools=[txt_search],
+    verbose=True
+)
+```
+
+## Input Schema
+
+The tool supports two input schemas depending on initialization:
+
+### Dynamic File Path Schema
+```python
+class TXTSearchToolSchema(BaseModel):
+    search_query: str  # The semantic search query
+    txt: str          # Path to the text file to search

+
+    Returns:
+        str: Relevant text passages based on semantic search
+    """
+```
+
+## Best Practices
+
+1. Choose initialization method based on use case:

+    backstory='Expert at finding relevant information in videos.',
+    tools=[video_tool],
+    verbose=True
+)
+```
+
+## Input Schema
+
+### Fixed Video Schema (when URL provided during initialization)
+```python
+class FixedYoutubeVideoSearchToolSchema(BaseModel):
+    search_query: str = Field(
+        description="Mandatory search query you want to use to search the Youtube Video content"
+    )
+```
+
+### Flexible Video Schema (when URL provided at runtime)
+```python
+class YoutubeVideoSearchToolSchema(FixedYoutubeVideoSearchToolSchema):
+    youtube_video_url: str = Field(
+        description="Mandatory youtube_video_url path you want to search"
+    )
+```
+
+## Function Signature
+
+```python
+def __init__(
+    self,
+    youtube_video_url: Optional[str] = None,
+    **kwargs
+):
+    """
+    Initialize the YouTube video search tool.
+
+    Args:
+        youtube_video_url (Optional[str]): URL of YouTube video (optional)
+        **kwargs: Additional arguments for RAG tool configuration
+    """
+
+def _run(
+    self,
+    search_query: str,
+    **kwargs: Any
+) -> str:
+    """
+    Execute semantic search on video content.
+
+    Args:
+        search_query (str): Query to search in the video
+        **kwargs: Additional arguments including youtube_video_url if not initialized
+
+    Returns:
+        str: Relevant content from the video matching the query
+    """
+```
+
+## Best Practices
+
+1. Video URL Management:
+   - Use complete YouTube URLs
+   - Verify video accessibility
+   - Handle region restrictions
+
+2. Search Optimization:
+   - Use specific, focused queries
+   - Consider video context
+   - Test with sample queries first
+
+3. Performance Considerations:
+   - Pre-initialize for repeated searches
+   - Handle long videos appropriately
+   - Monitor processing time
+
+4. Error Handling:
+   - Verify video availability
+   - Handle unavailable videos
+   - Manage API limitations
+
+## Integration Example
+
+```python
+from crewai import Agent, Task, Crew
+from crewai_tools import YoutubeVideoSearchTool
+
+# Initialize tool with specific video
+video_tool = YoutubeVideoSearchTool(
+    youtube_video_url="https://www.youtube.com/watch?v=example"
+)
+
+# Create agent
+researcher = Agent(
+    role='Video Researcher',
+    goal='Extract insights from video content',
+    backstory='Expert at analyzing video content.',
+    tools=[video_tool]
+)
+
+# Define task
+research_task = Task(
+    description="""Find all mentions of machine learning 
+    applications from the video content.""",
+    agent=researcher
+)
+
+# The tool will use:
+# {
+#   "search_query": "machine learning applications"
+# }
+
+# Create crew
+crew = Crew(
+    agents=[researcher],
+    tasks=[research_task]
+)
+
+# Execute
+result = crew.kickoff()
+```
+
+## Advanced Usage
+
+### Dynamic Video Selection
+```python
+# Initialize without video URL
+flexible_tool = YoutubeVideoSearchTool()
+
+# Search different videos
+tech_results = flexible_tool.run(
+    search_query="quantum computing",
+    youtube_video_url="https://youtube.com/watch?v=tech123"
+)
+
+science_results = flexible_tool.run(
+    search_query="particle physics",
+    youtube_video_url="https://youtube.com/watch?v=science456"
+)
+```
+
+### Multiple Video Analysis
+```python
+# Create tools for different videos
+tech_tool = YoutubeVideoSearchTool(
+    youtube_video_url="https://youtube.com/watch?v=tech123"
+)
+science_tool = YoutubeVideoSearchTool(
+    youtube_video_url="https://youtube.com/watch?v=science456"
+)
+
+# Create agent with multiple tools
+analyst = Agent(
+    role='Content Analyst',
+    goal='Cross-reference multiple videos',
+    tools=[tech_tool, science_tool]
+)
+```
+
+### Error Handling Example
+```python
+try:
+    video_tool = YoutubeVideoSearchTool()
+    results = video_tool.run(
+        search_query="key concepts",
+        youtube_video_url="https://youtube.com/watch?v=example"
+    )
+    print(results)
+except Exception as e:
+    print(f"Error processing video: {str(e)}")
+```
+

+      (AI) has rapidly evolved to become an integral part of our modern world, driving
+      significant advancements across various industries. AI refers to the simulation
+      of human intelligence in machines programmed to think and learn like humans.
+      This technology enables machines to analyze data, recognize patterns, and make
+      decisions with minimal human intervention, paving the way for innovation in
+      fields like healthcare, finance, and transportation.\\n\\nAI Agents, in particular,
+      embody the future of artificial intelligence by acting autonomously to perform
+      complex tasks. These agents leverage machine learning and natural language processing
+      to interact with users and understand their needs. They're deployed in customer
+      service applications, virtual assistants, and personal scheduling tools, showcasing
+      their capability to streamline processes and enhance user experience. By mimicking
+      human reasoning, AI Agents can adapt to changing situations and provide personalized
+      solutions.\\n\\nThe applications of AI Agents extend beyond mere task completion;
+      they are transforming the way businesses operate. In the realm of customer engagement,
+      AI Agents analyze customer behavior to provide insights that help companies
+      tailor their offerings. In healthcare, they assist in diagnosing illnesses by
+      analyzing patient data and suggesting treatments. The versatility of AI Agents
+      makes them invaluable assets in our increasingly automated world.\\n\\nAs we
+      look to the future, the potential of AI continues to expand. With ongoing advancements
+      in technology, AI Agents are set to become even more sophisticated, further
+      bridging the gap between humans and machines. The prospects of AI promise not
+      only to improve efficiency and productivity but also to change the way we live
+      and work, promising a future where intelligent, autonomous agents support us
+      in our daily lives.\",\n        \"refusal\": null\n      },\n      \"logprobs\":

+      Answer: \\n\\n**Overview of AI Agents**  \\nAI agents are advanced software
+      systems designed to autonomously perform tasks, make decisions, and learn from
+      their environments without needing constant human intervention. They leverage
+      machine learning, natural language processing, and various AI techniques to
+      simulate human-like understanding and autonomy. These agents can be categorized
+      into three types: reactive agents (which operate purely based on their environment),
+      deliberative agents (which can make decisions based on reasoning), and hybrid
+      agents that incorporate aspects of both types. Their ability to adapt and learn
+      over time makes them instrumental in automating processes across various domains.\\n\\n**Functionalities
+      of AI Agents**  \\nThe core functionalities of AI agents include perception,
+      action, learning, and interaction. They perceive data through sensors or data
+      feeds, process information through algorithms, and take actions based on this
+      data. Machine learning allows them to refine their performance over time by
+      analyzing outcomes and adjusting their strategies accordingly. Interaction capabilities
+      enable them to communicate with users, providing insights, answering queries,
+      or even negotiating in some cases. These functionalities make AI agents invaluable
+      for tasks such as predictive analytics, personal assistance, and real-time decision-making
+      in complex systems.\\n\\n**Applications in Various Industries**  \\nAI agents
+      are already being utilized across multiple industries, demonstrating their versatility
+      and efficiency. In healthcare, AI agents assist in diagnostics by analyzing
+      medical records and suggesting treatment plans tailored to individual patients.
+      In finance, they power robo-advisors that manage investment portfolios, automate
+      trading strategies, and provide financial advice based on real-time market analysis.
+      Furthermore, in customer service, AI chatbots serve as virtual assistants, enhancing
+      user experience by providing instant support and resolving queries without human
+      intervention. The logistics and supply chain industries have also seen AI agents
+      optimize inventory management and route planning, significantly improving operational
+      efficiency.\\n\\n**Future Impact on Technology and Society**  \\nThe ongoing
+      development of AI agents is poised to have a profound impact on technology and
+      society. As these agents become more sophisticated, we can anticipate a shift
+      towards increased automation in both professional and personal spheres, leading
+      to enhanced productivity and new business models. However, this automation introduces
+      challenges such as job displacement and ethical considerations regarding decision-making
+      by AI. It is essential to foster an ongoing dialogue on the implications of
+      AI agents to ensure responsible development and integration into our daily lives.
+      As AI agents continue to evolve, they will undoubtedly play a pivotal role in
+      shaping the future of technology and its intersection with societal dynamics,
+      making it critical for us to engage thoughtfully with this emerging paradigm.\",\n

+      I can compile this into a final answer following the specified format: a complete
+      four-paragraph article.\\n\\nFinal Answer: \\n\\n**Overview of AI Agents**  \\nAI
+      agents are advanced software systems designed to autonomously perform tasks,
+      make decisions, and learn from their environments without needing constant human
+      intervention. They leverage machine learning, natural language processing, and
+      various AI techniques to simulate human-like understanding and autonomy. These
+      agents can be categorized into three types: reactive agents (which operate purely
+      based on their environment), deliberative agents (which can make decisions based
+      on reasoning), and hybrid agents that incorporate aspects of both types. Their
+      ability to adapt and learn over time makes them instrumental in automating processes
+      across various domains.\\n\\n**Functionalities of AI Agents**  \\nThe core functionalities
+      of AI agents include perception, action, learning, and interaction. They perceive
+      data through sensors or data feeds, process information through algorithms,
+      and take actions based on this data. Machine learning allows them to refine
+      their performance over time by analyzing outcomes and adjusting their strategies
+      accordingly. Interaction capabilities enable them to communicate with users,
+      providing insights, answering queries, or even negotiating in some cases. These
+      functionalities make AI agents invaluable for tasks such as predictive analytics,
+      personal assistance, and real-time decision-making in complex systems.\\n\\n**Applications
+      in Various Industries**  \\nAI agents are already being utilized across multiple
+      industries, demonstrating their versatility and efficiency. In healthcare, AI
+      agents assist in diagnostics by analyzing medical records and suggesting treatment
+      plans tailored to individual patients. In finance, they power robo-advisors
+      that manage investment portfolios, automate trading strategies, and provide
+      financial advice based on real-time market analysis. Furthermore, in customer
+      service, AI chatbots serve as virtual assistants, enhancing user experience
+      by providing instant support and resolving queries without human intervention.
+      The logistics and supply chain industries have also seen AI agents optimize
+      inventory management and route planning, significantly improving operational
+      efficiency.\\n\\n**Future Impact on Technology and Society**  \\nThe ongoing
+      development of AI agents is poised to have a profound impact on technology and
+      society. As these agents become more sophisticated, we can anticipate a shift
+      towards increased automation in both professional and personal spheres, leading
+      to enhanced productivity and new business models. However, this automation introduces
+      challenges such as job displacement and ethical considerations regarding decision-making
+      by AI. It is essential to foster an ongoing dialogue on the implications of
