----
-
-# Event Listeners
-
-CrewAI provides a powerful event system that allows you to listen for and react to various events that occur during the execution of your Crew. This feature enables you to build custom integrations, monitoring solutions, logging systems, or any other functionality that needs to be triggered based on CrewAI's internal events.
-
-## How It Works
-
-CrewAI uses an event bus architecture to emit events throughout the execution lifecycle. The event system is built on the following components:
-
-1. **CrewAIEventsBus**: A singleton event bus that manages event registration and emission
-2. **CrewEvent**: Base class for all events in the system
-3. **BaseEventListener**: Abstract base class for creating custom event listeners
-
-When specific actions occur in CrewAI (like a Crew starting execution, an Agent completing a task, or a tool being used), the system emits corresponding events. You can register handlers for these events to execute custom code when they occur.
-
-## Creating a Custom Event Listener
-
-To create a custom event listener, you need to:
-
-1. Create a class that inherits from `BaseEventListener`
-2. Implement the `setup_listeners` method
-3. Register handlers for the events you're interested in
-4. Create an instance of your listener in the appropriate file
-
-Here's a simple example of a custom event listener class:
-
-```python
-from crewai.utilities.events import (
-    CrewKickoffStartedEvent,
-    CrewKickoffCompletedEvent,
-    AgentExecutionCompletedEvent,
-)
-from crewai.utilities.events.base_event_listener import BaseEventListener
-
-class MyCustomListener(BaseEventListener):
-    def __init__(self):
-        super().__init__()
-    
-    def setup_listeners(self, crewai_event_bus):
-        @crewai_event_bus.on(CrewKickoffStartedEvent)
-        def on_crew_started(source, event):
-            print(f"Crew '{event.crew_name}' has started execution!")
-        
-        @crewai_event_bus.on(CrewKickoffCompletedEvent)
-        def on_crew_completed(source, event):
-            print(f"Crew '{event.crew_name}' has completed execution!")
-            print(f"Output: {event.output}")
-        
-        @crewai_event_bus.on(AgentExecutionCompletedEvent)
-        def on_agent_execution_completed(source, event):
-            print(f"Agent '{event.agent.role}' completed task")
-            print(f"Output: {event.output}")
-```
-
-## Properly Registering Your Listener
-
-Simply defining your listener class isn't enough. You need to create an instance of it and ensure it's imported in your application. This ensures that:
-
-1. The event handlers are registered with the event bus
-2. The listener instance remains in memory (not garbage collected)
-3. The listener is active when events are emitted
-
-### Option 1: Import and Instantiate in Your Crew or Flow Implementation
-
-The most important thing is to create an instance of your listener in the file where your Crew or Flow is defined and executed:
-
-#### For Crew-based Applications
-
-Create and import your listener at the top of your Crew implementation file:
-
-```python
-# In your crew.py file
-from crewai import Agent, Crew, Task
-from my_listeners import MyCustomListener
-
-# Create an instance of your listener
-my_listener = MyCustomListener()
-
-class MyCustomCrew:
-    # Your crew implementation...
-    
-    def crew(self):
-        return Crew(
-            agents=[...],
-            tasks=[...],
-            # ...
-        )
-```
-
-#### For Flow-based Applications
-
-Create and import your listener at the top of your Flow implementation file:
-
-```python
-# In your main.py or flow.py file
-from crewai.flow import Flow, listen, start
-from my_listeners import MyCustomListener
-
-# Create an instance of your listener
-my_listener = MyCustomListener()
-
-class MyCustomFlow(Flow):
-    # Your flow implementation...
-    
-    @start()
-    def first_step(self):
-        # ...
-```
-
-This ensures that your listener is loaded and active when your Crew or Flow is executed.
-
-### Option 2: Create a Package for Your Listeners
-
-For a more structured approach, especially if you have multiple listeners:
-
-1. Create a package for your listeners:
-
-```
-my_project/
-  ├── listeners/
-  │   ├── __init__.py
-  │   ├── my_custom_listener.py
-  │   └── another_listener.py
-```
-
-2. In `my_custom_listener.py`, define your listener class and create an instance:
-
-```python
-# my_custom_listener.py
-from crewai.utilities.events.base_event_listener import BaseEventListener
-# ... import events ...
-
-class MyCustomListener(BaseEventListener):
-    # ... implementation ...
-
-# Create an instance of your listener
-my_custom_listener = MyCustomListener()
-```
-
-3. In `__init__.py`, import the listener instances to ensure they're loaded:
-
-```python
-# __init__.py
-from .my_custom_listener import my_custom_listener
-from .another_listener import another_listener
-
-# Optionally export them if you need to access them elsewhere
-__all__ = ['my_custom_listener', 'another_listener']
-```
-
-4. Import your listeners package in your Crew or Flow file:
-
-```python
-# In your crew.py or flow.py file
-import my_project.listeners  # This loads all your listeners
-
-class MyCustomCrew:
-    # Your crew implementation...
-```
-
-This is exactly how CrewAI's built-in `agentops_listener` is registered. In the CrewAI codebase, you'll find:
-
-```python
-# src/crewai/utilities/events/third_party/__init__.py
-from .agentops_listener import agentops_listener
-```
-
-This ensures the `agentops_listener` is loaded when the `crewai.utilities.events` package is imported.
-
-## Available Event Types
-
-CrewAI provides a wide range of events that you can listen for:
-
-### Crew Events
-
-- **CrewKickoffStartedEvent**: Emitted when a Crew starts execution
-- **CrewKickoffCompletedEvent**: Emitted when a Crew completes execution

-
-## Event Handler Structure
-
-Each event handler receives two parameters:
-
-1. **source**: The object that emitted the event
-2. **event**: The event instance, containing event-specific data
-
-The structure of the event object depends on the event type, but all events inherit from `CrewEvent` and include:
-
-- **timestamp**: The time when the event was emitted
-- **type**: A string identifier for the event type
-
-Additional fields vary by event type. For example, `CrewKickoffCompletedEvent` includes `crew_name` and `output` fields.
-
-## Real-World Example: Integration with AgentOps
-
-CrewAI includes an example of a third-party integration with [AgentOps](https://github.com/AgentOps-AI/agentops), a monitoring and observability platform for AI agents. Here's how it's implemented:
-
-```python
-from typing import Optional
-
-from crewai.utilities.events import (
-    CrewKickoffCompletedEvent,
-    ToolUsageErrorEvent,
-    ToolUsageStartedEvent,
-)
-from crewai.utilities.events.base_event_listener import BaseEventListener
-from crewai.utilities.events.crew_events import CrewKickoffStartedEvent
-from crewai.utilities.events.task_events import TaskEvaluationEvent
-
-try:
-    import agentops
-    AGENTOPS_INSTALLED = True
-except ImportError:
-    AGENTOPS_INSTALLED = False
-
-class AgentOpsListener(BaseEventListener):
-    tool_event: Optional["agentops.ToolEvent"] = None
-    session: Optional["agentops.Session"] = None
-
-    def __init__(self):
-        super().__init__()
-
-    def setup_listeners(self, crewai_event_bus):
-        if not AGENTOPS_INSTALLED:
-            return
-
-        @crewai_event_bus.on(CrewKickoffStartedEvent)
-        def on_crew_kickoff_started(source, event: CrewKickoffStartedEvent):
-            self.session = agentops.init()
-            for agent in source.agents:
-                if self.session:
-                    self.session.create_agent(
-                        name=agent.role,
-                        agent_id=str(agent.id),
-                    )
-
-        @crewai_event_bus.on(CrewKickoffCompletedEvent)
-        def on_crew_kickoff_completed(source, event: CrewKickoffCompletedEvent):
-            if self.session:
-                self.session.end_session(
-                    end_state="Success",
-                    end_state_reason="Finished Execution",
-                )
-
-        @crewai_event_bus.on(ToolUsageStartedEvent)
-        def on_tool_usage_started(source, event: ToolUsageStartedEvent):
-            self.tool_event = agentops.ToolEvent(name=event.tool_name)
-            if self.session:
-                self.session.record(self.tool_event)
-
-        @crewai_event_bus.on(ToolUsageErrorEvent)
-        def on_tool_usage_error(source, event: ToolUsageErrorEvent):
-            agentops.ErrorEvent(exception=event.error, trigger_event=self.tool_event)
-```
-
-This listener initializes an AgentOps session when a Crew starts, registers agents with AgentOps, tracks tool usage, and ends the session when the Crew completes.
-
-The AgentOps listener is registered in CrewAI's event system through the import in `src/crewai/utilities/events/third_party/__init__.py`:
-
-```python
-from .agentops_listener import agentops_listener
-```
-
-This ensures the `agentops_listener` is loaded when the `crewai.utilities.events` package is imported.
-
-## Advanced Usage: Scoped Handlers
-
-For temporary event handling (useful for testing or specific operations), you can use the `scoped_handlers` context manager:
-
-```python
-from crewai.utilities.events import crewai_event_bus, CrewKickoffStartedEvent
-
-with crewai_event_bus.scoped_handlers():
-    @crewai_event_bus.on(CrewKickoffStartedEvent)
-    def temp_handler(source, event):
-        print("This handler only exists within this context")
-    
-    # Do something that emits events
-    
-# Outside the context, the temporary handler is removed
-```
-
-## Use Cases
-
-Event listeners can be used for a variety of purposes:
-
-1. **Logging and Monitoring**: Track the execution of your Crew and log important events
-2. **Analytics**: Collect data about your Crew's performance and behavior
-3. **Debugging**: Set up temporary listeners to debug specific issues
-4. **Integration**: Connect CrewAI with external systems like monitoring platforms, databases, or notification services
-5. **Custom Behavior**: Trigger custom actions based on specific events
-
-## Best Practices
-
-1. **Keep Handlers Light**: Event handlers should be lightweight and avoid blocking operations
-2. **Error Handling**: Include proper error handling in your event handlers to prevent exceptions from affecting the main execution
-3. **Cleanup**: If your listener allocates resources, ensure they're properly cleaned up
-4. **Selective Listening**: Only listen for events you actually need to handle
-5. **Testing**: Test your event listeners in isolation to ensure they behave as expected
-
-By leveraging CrewAI's event system, you can extend its functionality and integrate it seamlessly with your existing infrastructure.

-## Running Flows
-
-There are two ways to run a flow:
-
-### Using the Flow API
-
-You can run a flow programmatically by creating an instance of your flow class and calling the `kickoff()` method:
-
-```python
-flow = ExampleFlow()
-result = flow.kickoff()
-```
-
-### Using the CLI
-
-Starting from version 0.103.0, you can run flows using the `crewai run` command:
-
-```shell
-crewai run
-```
-
-This command automatically detects if your project is a flow (based on the `type = "flow"` setting in your pyproject.toml) and runs it accordingly. This is the recommended way to run flows from the command line.
-
-For backward compatibility, you can also use:
-
-```shell
-crewai flow kickoff
-```
-
-However, the `crewai run` command is now the preferred method as it works for both crews and flows.

-```
-
-### Step 3: Initialize OpenLit
-
-Initialize the OpenLit OpenTelemetry instrumentation SDK to start capturing OpenTelemetry traces.
-
-
-```python
-import openlit
-
-openlit.init()
-```
-
-### Step 4: Create a Simple CrewAI Application
-
-We'll create a simple CrewAI application where multiple agents collaborate to answer a user's question.
-
-
-```python
-from crewai import Agent, Task, Crew
-
-from crewai_tools import (
-    WebsiteSearchTool
-)
-
-web_rag_tool = WebsiteSearchTool()
-
-writer = Agent(
-        role="Writer",
-        goal="You make math engaging and understandable for young children through poetry",
-        backstory="You're an expert in writing haikus but you know nothing of math.",
-        tools=[web_rag_tool],  
-    )
-
-task = Task(description=("What is {multiplication}?"),
-            expected_output=("Compose a haiku that includes the answer."),
-            agent=writer)
-
-crew = Crew(
-  agents=[writer],
-  tasks=[task],
-  share_crew=False
-)
-```
-
-### Step 5: See Traces in Langfuse
-
-After running the agent, you can view the traces generated by your CrewAI application in [Langfuse](https://cloud.langfuse.com). You should see detailed steps of the LLM interactions, which can help you debug and optimize your AI agent.

+# Portkey Integration with CrewAI
+<img src="https://raw.githubusercontent.com/siddharthsambharia-portkey/Portkey-Product-Images/main/Portkey-CrewAI.png" alt="Portkey CrewAI Header Image" width="70%" />
+
+
+[Portkey](https://portkey.ai/?utm_source=crewai&utm_medium=crewai&utm_campaign=crewai) is a 2-line upgrade to make your CrewAI agents reliable, cost-efficient, and fast.
+
+Portkey adds 4 core production capabilities to any CrewAI agent:
+1. Routing to **200+ LLMs**
+2. Making each LLM call more robust
+3. Full-stack tracing & cost, performance analytics
+4. Real-time guardrails to enforce behavior
+
+
+
+
+
+## Getting Started
+
+1. **Install Required Packages:**
+
+```bash
+pip install -qU crewai portkey-ai
+```
+
+2. **Configure the LLM Client:**
+
+To build CrewAI Agents with Portkey, you'll need two keys:
+- **Portkey API Key**: Sign up on the [Portkey app](https://app.portkey.ai/?utm_source=crewai&utm_medium=crewai&utm_campaign=crewai) and copy your API key
+- **Virtual Key**: Virtual Keys securely manage your LLM API keys in one place. Store your LLM provider API keys securely in Portkey's vault
+
+```python
+from crewai import LLM
+from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
+
+gpt_llm = LLM(
+    model="gpt-4",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy", # We are using Virtual key
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_VIRTUAL_KEY", # Enter your Virtual key from Portkey
+    )
+)
+```
+
+3. **Create and Run Your First Agent:**
+
+```python
+from crewai import Agent, Task, Crew
+
+# Define your agents with roles and goals
+coder = Agent(
+    role='Software developer',
+    goal='Write clear, concise code on demand',
+    backstory='An expert coder with a keen eye for software trends.',
+    llm=gpt_llm
+)
+
+# Create tasks for your agents
+task1 = Task(
+    description="Define the HTML for making a simple website with heading- Hello World! Portkey is working!",
+    expected_output="A clear and concise HTML code",
+    agent=coder
+)
+
+# Instantiate your crew
+crew = Crew(
+    agents=[coder],
+    tasks=[task1],
+)
+
+result = crew.kickoff()
+print(result)
+```
+
+

+</Frame>
+
+
+### 1. Use 250+ LLMs
+Access various LLMs like Anthropic, Gemini, Mistral, Azure OpenAI, and more with minimal code changes. Switch between providers or use them together seamlessly. [Learn more about Universal API](https://portkey.ai/docs/product/ai-gateway/universal-api)
+
+
+Easily switch between different LLM providers:
+
+```python
+# Anthropic Configuration
+anthropic_llm = LLM(
+    model="claude-3-5-sonnet-latest",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_ANTHROPIC_VIRTUAL_KEY", #You don't need provider when using Virtual keys
+        trace_id="anthropic_agent"
+    )
+)
+
+# Azure OpenAI Configuration
+azure_llm = LLM(
+    model="gpt-4",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_AZURE_VIRTUAL_KEY", #You don't need provider when using Virtual keys
+        trace_id="azure_agent"
+    )
+)
+```
+
+
+### 2. Caching
+Improve response times and reduce costs with two powerful caching modes:
+- **Simple Cache**: Perfect for exact matches
+- **Semantic Cache**: Matches responses for requests that are semantically similar
+[Learn more about Caching](https://portkey.ai/docs/product/ai-gateway/cache-simple-and-semantic)
+
+```py
+config = {
+    "cache": {
+        "mode": "semantic",  # or "simple" for exact matching
+    }
+}
+```
+
+### 3. Production Reliability
+Portkey provides comprehensive reliability features:
+- **Automatic Retries**: Handle temporary failures gracefully
+- **Request Timeouts**: Prevent hanging operations
+- **Conditional Routing**: Route requests based on specific conditions
+- **Fallbacks**: Set up automatic provider failovers
+- **Load Balancing**: Distribute requests efficiently
+
+[Learn more about Reliability Features](https://portkey.ai/docs/product/ai-gateway/)
+
+
+
+### 4. Metrics
+
+Agent runs are complex. Portkey automatically logs **40+ comprehensive metrics** for your AI agents, including cost, tokens used, latency, etc. Whether you need a broad overview or granular insights into your agent runs, Portkey's customizable filters provide the metrics you need.
+
+
+- Cost per agent interaction
+- Response times and latency
+- Token usage and efficiency
+- Success/failure rates
+- Cache hit rates
+

+
+### 5. Detailed Logging
+Logs are essential for understanding agent behavior, diagnosing issues, and improving performance. They provide a detailed record of agent activities and tool use, which is crucial for debugging and optimizing processes.
+
+
+Access a dedicated section to view records of agent executions, including parameters, outcomes, function calls, and errors. Filter logs based on multiple parameters such as trace ID, model, tokens used, and metadata.
+
+<details>
+  <summary><b>Traces</b></summary>

-CrewAI uses the `uv` as its dependency management and package handling tool. It simplifies project setup and execution, offering a seamless experience.
+# Setting Up Your Environment
 
-If you haven't installed `uv` yet, follow **step 1** to quickly get it set up on your system, else you can skip to **step 2**.
+Before installing CrewAI, it's recommended to set up a virtual environment. This helps isolate your project dependencies and avoid conflicts.
 
 <Steps>
-    <Step title="Install uv">
-      - **On macOS/Linux:**
+    <Step title="Create a Virtual Environment">
+        Choose your preferred method to create a virtual environment:
 
-        Use `curl` to download the script and execute it with `sh`:
-
-        ```shell
-        curl -LsSf https://astral.sh/uv/install.sh | sh
-        ```
-        If your system doesn't have `curl`, you can use `wget`:
-
-        ```shell
-        wget -qO- https://astral.sh/uv/install.sh | sh
+        **Using venv (Python's built-in tool):**
+        ```shell Terminal
+        python3 -m venv .venv
         ```
 
-      - **On Windows:**
-
-        Use `irm` to download the script and `iex` to execute it:
-
-        ```shell
-        powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
+        **Using conda:**
+        ```shell Terminal
+        conda create -n crewai-env python=3.12
         ```
-        If you run into any issues, refer to [UV's installation guide](https://docs.astral.sh/uv/getting-started/installation/) for more information.
     </Step>
 
-    <Step title="Install CrewAI 🚀">
-      - Run the following command to install `crewai` CLI:
-        ```shell
-        uv tool install crewai
-        ```
-          <Warning>
-            If you encounter a `PATH` warning, run this command to update your shell:
-            ```shell
-            uv tool update-shell
-            ```
-          </Warning>
+    <Step title="Activate the Virtual Environment">
+        Activate your virtual environment based on your platform:
 
-      - To verify that `crewai` is installed, run:
-        ```shell
-        uv tools list
+        **On macOS/Linux (venv):**
+        ```shell Terminal
+        source .venv/bin/activate
         ```
-      - You should see something like:
-        ```markdown
-        crewai v0.102.0
-        - crewai
+
+        **On Windows (venv):**
+        ```shell Terminal
+        .venv\Scripts\activate
+        ```
+
+        **Using conda (all platforms):**
+        ```shell Terminal
+        conda activate crewai-env
         ```

+Use the annotations to properly reference the agent and task in the `crew.py` file.
+
+### Annotations include:
+
+Here are examples of how to use each annotation in your CrewAI project, and when you should use them:
+
+#### @agent
+Used to define an agent in your crew. Use this when:
+- You need to create a specialized AI agent with a specific role
+- You want the agent to be automatically collected and managed by the crew
+- You need to reuse the same agent configuration across multiple tasks
+
+```python
+@agent
+def research_agent(self) -> Agent:
+    return Agent(
+        role="Research Analyst",
+        goal="Conduct thorough research on given topics",
+        backstory="Expert researcher with years of experience in data analysis",
+        tools=[SerperDevTool()],
+        verbose=True
+    )
+```
+
+#### @task
+Used to define a task that can be executed by agents. Use this when:
+- You need to define a specific piece of work for an agent
+- You want tasks to be automatically sequenced and managed
+- You need to establish dependencies between different tasks
+
+```python
+@task
+def research_task(self) -> Task:
+    return Task(
+        description="Research the latest developments in AI technology",
+        expected_output="A comprehensive report on AI advancements",
+        agent=self.research_agent(),
+        output_file="output/research.md"
+    )
+```
+
+#### @crew
+Used to define your crew configuration. Use this when:
+- You want to automatically collect all @agent and @task definitions
+- You need to specify how tasks should be processed (sequential or hierarchical)
+- You want to set up crew-wide configurations
+
+```python
+@crew
+def research_crew(self) -> Crew:
+    return Crew(
+        agents=self.agents,  # Automatically collected from @agent methods
+        tasks=self.tasks,    # Automatically collected from @task methods
+        process=Process.sequential,
+        verbose=True
+    )
+```
+
+#### @tool
+Used to create custom tools for your agents. Use this when:
+- You need to give agents specific capabilities (like web search, data analysis)
+- You want to encapsulate external API calls or complex operations
+- You need to share functionality across multiple agents
+
+```python
+@tool
+def web_search_tool(query: str, max_results: int = 5) -> list[str]:
+    """
+    Search the web for information.
+
+    Args:
+        query: The search query
+        max_results: Maximum number of results to return
+
+    Returns:
+        List of search results
+    """
+    # Implement your search logic here
+    return [f"Result {i} for: {query}" for i in range(max_results)]
+```
+
+#### @before_kickoff
+Used to execute logic before the crew starts. Use this when:
+- You need to validate or preprocess input data
+- You want to set up resources or configurations before execution
+- You need to perform any initialization logic
+
+```python
+@before_kickoff
+def validate_inputs(self, inputs: Optional[Dict[str, Any]]) -> Optional[Dict[str, Any]]:
+    """Validate and preprocess inputs before the crew starts."""
+    if inputs is None:
+        return None
+        
+    if 'topic' not in inputs:
+        raise ValueError("Topic is required")
+    
+    # Add additional context
+    inputs['timestamp'] = datetime.now().isoformat()
+    inputs['topic'] = inputs['topic'].strip().lower()
+    return inputs
+```
+
+#### @after_kickoff
+Used to process results after the crew completes. Use this when:
+- You need to format or transform the final output
+- You want to perform cleanup operations
+- You need to save or log the results in a specific way
+
+```python
+@after_kickoff
+def process_results(self, result: CrewOutput) -> CrewOutput:
+    """Process and format the results after the crew completes."""
+    result.raw = result.raw.strip()
+    result.raw = f"""
+    # Research Results
+    Generated on: {datetime.now().isoformat()}
+    
+    {result.raw}
+    """
+    return result
+```
+
+#### @callback
+Used to handle events during crew execution. Use this when:
+- You need to monitor task progress
+- You want to log intermediate results
+- You need to implement custom progress tracking or metrics
+
+```python
+@callback
+def log_task_completion(self, task: Task, output: str):
+    """Log task completion details for monitoring."""
+    print(f"Task '{task.description}' completed")
+    print(f"Output length: {len(output)} characters")
+    print(f"Agent used: {task.agent.role}")
+    print("-" * 50)
+```
+
+#### @cache_handler
+Used to implement custom caching for task results. Use this when:
+- You want to avoid redundant expensive operations
+- You need to implement custom cache storage or expiration logic
+- You want to persist results between runs
+
+```python
+@cache_handler
+def custom_cache(self, key: str) -> Optional[str]:
+    """Custom cache implementation for storing task results."""
+    cache_file = f"cache/{key}.json"
+    
+    if os.path.exists(cache_file):
+        with open(cache_file, 'r') as f:
+            data = json.load(f)
+            # Check if cache is still valid (e.g., not expired)
+            if datetime.fromisoformat(data['timestamp']) > datetime.now() - timedelta(days=1):
+                return data['result']
+    return None
+```
+
+<Note>
+These decorators are part of the CrewAI framework and help organize your crew's structure by automatically collecting agents, tasks, and handling various lifecycle events. 
+They should be used within a class decorated with `@CrewBase`.
+</Note>
+
+### Replay Tasks from Latest Crew Kickoff
+
+CrewAI now includes a replay feature that allows you to list the tasks from the last run and replay from a specific one. To use this feature, run.
+
+```shell
+crewai replay <task_id>
+```
+
+Replace `<task_id>` with the ID of the task you want to replay.
+
+### Reset Crew Memory
+
+If you need to reset the memory of your crew before running it again, you can do so by calling the reset memory feature:
+
+```shell
+crewai reset-memories --all
+```
+
+This will clear the crew's memory, allowing for a fresh start.
+

-    agents=[data_analyst],
-    tasks=[analysis_task],
-    verbose=True,
-    process=Process.sequential,
-)
-result = crew.kickoff()
-```
-
-## Implementation Details
-
-The `CodeInterpreterTool` uses Docker to create a secure environment for code execution:
-
-```python Code
-class CodeInterpreterTool(BaseTool):
-    name: str = "Code Interpreter"
-    description: str = "Interprets Python3 code strings with a final print statement."
-    args_schema: Type[BaseModel] = CodeInterpreterSchema
-    default_image_tag: str = "code-interpreter:latest"
-    
-    def _run(self, **kwargs) -> str:
-        code = kwargs.get("code", self.code)
-        libraries_used = kwargs.get("libraries_used", [])
-
-        if self.unsafe_mode:
-            return self.run_code_unsafe(code, libraries_used)
-        else:
-            return self.run_code_in_docker(code, libraries_used)
-```
-
-The tool performs the following steps:
-1. Verifies that the Docker image exists or builds it if necessary
-2. Creates a Docker container with the current working directory mounted
-3. Installs any required libraries specified by the agent
-4. Executes the Python code in the container
-5. Returns the output of the code execution
-6. Cleans up by stopping and removing the container
-
-## Security Considerations
-
-By default, the `CodeInterpreterTool` runs code in an isolated Docker container, which provides a layer of security. However, there are still some security considerations to keep in mind:
-
-1. The Docker container has access to the current working directory, so sensitive files could potentially be accessed.
-2. The `unsafe_mode` parameter allows code to be executed directly on the host machine, which should only be used in trusted environments.
-3. Be cautious when allowing agents to install arbitrary libraries, as they could potentially include malicious code.
-
-## Conclusion
-
-The `CodeInterpreterTool` provides a powerful way for CrewAI agents to execute Python code in a relatively secure environment. By enabling agents to write and run code, it significantly expands their problem-solving capabilities, especially for tasks involving data analysis, calculations, or other computational work. This tool is particularly useful for agents that need to perform complex operations that are more efficiently expressed in code than in natural language.

-
-## Tool Parameters
-
-### Required Parameters
-- `qdrant_url` (str): The URL of your Qdrant server
-- `qdrant_api_key` (str): API key for authentication with Qdrant
-- `collection_name` (str): Name of the Qdrant collection to search
-
-### Optional Parameters
-- `limit` (int): Maximum number of results to return (default: 3)
-- `score_threshold` (float): Minimum similarity score threshold (default: 0.35)
-- `custom_embedding_fn` (Callable[[str], list[float]]): Custom function for text vectorization
-
-## Search Parameters
-
-The tool accepts these parameters in its schema:
-- `query` (str): The search query to find similar documents
-- `filter_by` (str, optional): Metadata field to filter on
-- `filter_value` (str, optional): Value to filter by
-
-## Return Format
-
-The tool returns results in JSON format:
-
-```json
-[
-  {
-    "metadata": {
-      // Any metadata stored with the document
-    },
-    "context": "The actual text content of the document",
-    "distance": 0.95  // Similarity score
-  }
-]
-```
-
-## Default Embedding
-
-By default, the tool uses OpenAI's `text-embedding-3-small` model for vectorization. This requires:
-- OpenAI API key set in environment: `OPENAI_API_KEY`
-
-## Custom Embeddings
-
-Instead of using the default embedding model, you might want to use your own embedding function in cases where you:
-
-1. Want to use a different embedding model (e.g., Cohere, HuggingFace, Ollama models)
-2. Need to reduce costs by using open-source embedding models
-3. Have specific requirements for vector dimensions or embedding quality
-4. Want to use domain-specific embeddings (e.g., for medical or legal text)
-
-Here's an example using a HuggingFace model:
-
-```python
-from transformers import AutoTokenizer, AutoModel
-import torch
-
-# Load model and tokenizer
-tokenizer = AutoTokenizer.from_pretrained('sentence-transformers/all-MiniLM-L6-v2')
-model = AutoModel.from_pretrained('sentence-transformers/all-MiniLM-L6-v2')
-
-def custom_embeddings(text: str) -> list[float]:
-    # Tokenize and get model outputs
-    inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True)
-    outputs = model(**inputs)
-    
-    # Use mean pooling to get text embedding
-    embeddings = outputs.last_hidden_state.mean(dim=1)
-    
-    # Convert to list of floats and return
-    return embeddings[0].tolist()
-
-# Use custom embeddings with the tool
-tool = QdrantVectorSearchTool(
-    qdrant_url="your_url",
-    qdrant_api_key="your_key",
-    collection_name="your_collection",
-    custom_embedding_fn=custom_embeddings  # Pass your custom function
-)
-```
-
-## Error Handling
-
-The tool handles these specific errors:
-- Raises ImportError if `qdrant-client` is not installed (with option to auto-install)
-- Raises ValueError if `QDRANT_URL` is not set
-- Prompts to install `qdrant-client` if missing using `uv add qdrant-client`
-
-## Environment Variables
-
-Required environment variables:
-```bash
-export QDRANT_URL="your_qdrant_url"  # If not provided in constructor
-export QDRANT_API_KEY="your_api_key"  # If not provided in constructor
-export OPENAI_API_KEY="your_openai_key"  # If using default embeddings

-
-# Define an agent that uses the tool
-web_scraper_agent = Agent(
-    role="Web Scraper",
-    goal="Extract and analyze information from dynamic websites",
-    backstory="""You are an expert web scraper who specializes in extracting 
-    content from dynamic websites that require browser automation. You have 
-    extensive knowledge of CSS selectors and can identify the right selectors 
-    to target specific content on any website.""",
-    tools=[selenium_tool],
-    verbose=True,
-)
-
-# Create a task for the agent
-scrape_task = Task(
-    description="""
-    Extract the following information from the news website at {website_url}:
-    
-    1. The headlines of all featured articles (CSS selector: '.headline')
-    2. The publication dates of these articles (CSS selector: '.pub-date')
-    3. The author names where available (CSS selector: '.author')
-    
-    Compile this information into a structured format with each article's details grouped together.
-    """,
-    expected_output="A structured list of articles with their headlines, publication dates, and authors.",
-    agent=web_scraper_agent,
-)

-    tasks=[scrape_task],
-    verbose=True,
-    process=Process.sequential,
-)
-result = crew.kickoff(inputs={"website_url": "https://news-example.com"})
-```
-
-## Implementation Details
-
-The `SeleniumScrapingTool` uses Selenium WebDriver to automate browser interactions:
-
-```python Code
-class SeleniumScrapingTool(BaseTool):
-    name: str = "Read a website content"
-    description: str = "A tool that can be used to read a website content."
-    args_schema: Type[BaseModel] = SeleniumScrapingToolSchema
-    
-    def _run(self, **kwargs: Any) -> Any:
-        website_url = kwargs.get("website_url", self.website_url)
-        css_element = kwargs.get("css_element", self.css_element)
-        return_html = kwargs.get("return_html", self.return_html)
-        driver = self._create_driver(website_url, self.cookie, self.wait_time)
-
-        content = self._get_content(driver, css_element, return_html)
-        driver.close()
-
-        return "\n".join(content)
-```
-
-The tool performs the following steps:
-1. Creates a headless Chrome browser instance
-2. Navigates to the specified URL
-3. Waits for the specified time to allow the page to load
-4. Adds any cookies if provided
-5. Extracts content based on the CSS selector
-6. Returns the extracted content as text or HTML
-7. Closes the browser instance
-
-## Handling Dynamic Content
-
-The `SeleniumScrapingTool` is particularly useful for scraping websites with dynamic content that is loaded via JavaScript. By using a real browser instance, it can:
-
-1. Execute JavaScript on the page
-2. Wait for dynamic content to load
-3. Interact with elements if needed

-## Implementation Details
-
-The `YoutubeVideoSearchTool` is implemented as a subclass of `RagTool`, which provides the base functionality for Retrieval-Augmented Generation:
-
-```python Code
-class YoutubeVideoSearchTool(RagTool):
-    name: str = "Search a Youtube Video content"
-    description: str = "A tool that can be used to semantic search a query from a Youtube Video content."
-    args_schema: Type[BaseModel] = YoutubeVideoSearchToolSchema
-
-    def __init__(self, youtube_video_url: Optional[str] = None, **kwargs):
-        super().__init__(**kwargs)
-        if youtube_video_url is not None:
-            kwargs["data_type"] = DataType.YOUTUBE_VIDEO
-            self.add(youtube_video_url)
-            self.description = f"A tool that can be used to semantic search a query the {youtube_video_url} Youtube Video content."
-            self.args_schema = FixedYoutubeVideoSearchToolSchema
-            self._generate_description()
-```
-
-## Conclusion
-
-The `YoutubeVideoSearchTool` provides a powerful way to search and extract information from YouTube video content using RAG techniques. By enabling agents to search within video content, it facilitates information extraction and analysis tasks that would otherwise be difficult to perform. This tool is particularly useful for research, content analysis, and knowledge extraction from video sources.
