Detailed Explanation of Classes in Multi-Agent Chat Code
This document provides a detailed explanation of each class in your multi-agent chat code. Each section includes the purpose, how it works (with explanation of each step, purpose, key points, parameters, and results), and key points to remember.

1. SelectionStrategy
   class SelectionStrategy(SequentialSelectionStrategy):
   """A strategy for determining which agent should take the next turn in the chat."""

   Select the next agent that should take the next turn in the chat

   async def select_agent(self, agents, history):
   """Check which agent should take the next turn in the chat."""

    # The Incident Manager should go after the User or the Devops Assistant
    if (history[-1].name == DEVOPS_ASSISTANT or history[-1].role == AuthorRole.USER):
        agent_name = INCIDENT_MANAGER
        return next((agent for agent in agents if agent.name == agent_name), None)
        
    # Otherwise it is the DevOps Assistant's turn
    return next((agent for agent in agents if agent.name == DEVOPS_ASSISTANT), None)
   

How It Works
Purpose: Implements a strategy to determine which agent should respond next in the chat.
Key Points:
Extends the SequentialSelectionStrategy class to define custom logic for agent selection.
Uses the chat history to decide the next agent.
Parameters:
agents: A list of all agents participating in the chat.
history: A list of previous messages in the chat, used to determine context.
Results:
Returns the next agent to respond based on the last message in the history.
If the last message was from the user or the DevOps Assistant, the Incident Manager responds next.
Otherwise, the DevOps Assistant responds.
Key Points to Remember
Selection logic is based on the chat history.
This strategy ensures an alternating conversation flow between agents.
Extensibility allows for more complex selection logic in the future.
2. ApprovalTerminationStrategy
class ApprovalTerminationStrategy(TerminationStrategy):
"""A strategy for determining when an agent should terminate."""

# End the chat if the agent has indicated there is no action needed
async def should_agent_terminate(self, agent, history):
    """Check if the agent should terminate."""
    return "no action needed" in history[-1].content.lower()

How It Works
Purpose: Defines when the chat should end based on the agent's output.
Key Points:
Extends the TerminationStrategy class to implement custom termination logic.
Checks the content of the last message in the chat history to determine if termination is needed.
Parameters:
agent: The agent whose termination status is being checked.
history: A list of all messages in the chat, used to analyze the most recent message.
Results:
Returns True if the last message indicates that no further action is needed.
Otherwise, returns False, allowing the chat to continue.
Key Points to Remember
The termination logic is based on the content of the last message.
This strategy ensures that the chat ends when no further actions are required.
Custom termination logic can be extended for more complex scenarios.
3. DevopsPlugin
class DevopsPlugin:
"""A plugin that performs developer operation tasks."""

def append_to_log_file(self, filepath: str, content: str) -> None:
    with open(filepath, 'a', encoding='utf-8') as file:
        file.write('\n' + textwrap.dedent(content).strip())

@kernel_function(description="A function that restarts the named service")
def restart_service(self, service_name: str = "", logfile: str = "") -> str:
    log_entries = [
        f"[{datetime.now().strftime('%Y-%m-%d %H:%M:%S')}] ALERT  DevopsAssistant: Multiple failures detected in {service_name}. Restarting service.",
        f"[{datetime.now().strftime('%Y-%m-%d %H:%M:%S')}] INFO  {service_name}: Restart initiated.",
        f"[{datetime.now().strftime('%Y-%m-%d %H:%M:%S')}] INFO  {service_name}: Service restarted successfully.",
    ]
    log_message = "\n".join(log_entries)
    self.append_to_log_file(logfile, log_message)
    return f"Service {service_name} restarted successfully."

How It Works
Purpose: Provides functions for common DevOps tasks, such as restarting services or updating logs.
Key Points:
append_to_log_file(): Appends a message to a log file.
restart_service(): Restarts a service and logs the operation.
Parameters:
filepath: The path to the log file.
content: The message to append to the log file.
service_name: The name of the service to restart.
logfile: The log file where the operation is recorded.
Results:
Log entries are appended to the specified log file.
Returns a confirmation message indicating the success of the operation.
Key Points to Remember
The plugin extends the functionality of the DevOps Assistant agent.
Functions like restart_service() are decorated with @kernel_function to expose them to the agent.
Log file management is an essential part of the plugin's functionality.
4. LogFilePlugin
class LogFilePlugin:
"""A plugin that reads and writes log files."""

@kernel_function(description="Accesses the given file path string and returns the file contents as a string")
def read_log_file(self, filepath: str = "") -> str:
    with open(filepath, 'r', encoding='utf-8') as file:
        return file.read()

How It Works
Purpose: Provides functionality for reading log files.
Key Points:
read_log_file(): Reads the contents of a log file and returns it as a string.
Parameters:
filepath: The path to the log file to be read.
Results:
Reads the entire contents of the specified log file.
Returns the log file contents as a string.
Key Points to Remember
The plugin simplifies log file access for the Incident Manager agent.
Functionality is exposed to the agent using the @kernel_function decorator.
