import os
import autogen
from IPython.show import show, Markdown

Step 2: Calling the API

To make use of the Llama 4, we now have to load the Collectively API. The code block beneath will assist us load the APIs and configure them to the atmosphere.

with open("together_ai_api.txt") as file:
   LLAMA_API_KEY = file.learn().strip()
os.environ["LLAMA_API_KEY"] = LLAMA_API_KEY

Step 3: Creating Brokers and Defining Duties

Now, let’s create the required brokers and outline their duties, i.e., what they’ll do.

1. Shopper Enter Agent

The Shopper Enter agent acts as the first interface between the human person and the agent system. It collects mission particulars like consumer necessities, timeline, and price range from the person and passes them to the Scope Architect. It additionally relays follow-up questions and solutions, and indicators termination when the ultimate proposal is accepted.

Anticipated Output:

• Clear transmission of the person’s mission description and freelancer profile (abilities, expertise, time estimate).
• Ends the session as soon as a passable proposal is delivered, or the person will explicitly finish it.

# Agent 1: Handles Human Enter for Shopper Necessities
client_agent = autogen.UserProxyAgent(
   identify="Client_Input_Agent",
   human_input_mode="ALWAYS",  # asks the human for enter
   max_consecutive_auto_reply=1, # Solely reply as soon as
   is_termination_msg=lambda x: x.get("content material", "").rstrip().endswith("TERMINATE"),
   system_message="""You're the main level of contact for the person.
   Your first activity is to offer the preliminary mission particulars acquired from the human person (consumer necessities, product particulars, timeline, price range) to the group chat.
   After the Scope Architect asks questions, relay the human person's solutions about their abilities, expertise, instruments, and time estimate again to the chat.
   Reply TERMINATE when the ultimate proposal is generated and passable, or if the person needs to cease. In any other case, relay the person's enter.
   """,
)

2. Scope Architect Agent

The Scope Architect Agent is accountable for the preliminary mission particulars from the Shopper Enter Agent. After that, it asks particular questions to assemble the freelancer’s abilities, instruments, previous mission expertise, and estimated time to finish the work. It doesn’t proceed to proposal era itself however ensures that each one the required context is collected earlier than handing it over to the following agent.

Anticipated Output:

• Nicely-structured abstract combining each the consumer’s mission wants and the freelancer’s capabilities.
• Triggers the Price Recommender Agent as soon as all required information is collected and summarized.

# Agent 2: Gathers Consumer's Profile and Estimates
scope_architect_agent = autogen.AssistantAgent(
   identify="Scope_Architect",
   llm_config=llm_config,
   human_input_mode="ALWAYS",
   max_consecutive_auto_reply=1, # Solely reply as soon as 
   is_termination_msg=lambda x: x.get("content material", "").rstrip().endswith("TERMINATE"),
   system_message="""You're a Scope Architect. Your position is to know the mission necessities supplied initially after which collect crucial particulars *from the Client_Input_Agent (representing the person/freelancer)*.
   1. Look ahead to the preliminary mission particulars from Client_Input_Agent.
   2. Upon getting the mission particulars, formulate clear questions for the Client_Input_Agent to ask the human person about their:
       - Related previous work/tasks and collaborations.
       - Key abilities and instruments relevant to this mission.
       - Their estimated time to finish the outlined work.
   3. Do NOT proceed to proposal era. Look ahead to the Client_Input_Agent to offer the person's solutions.
   4. Upon getting each the consumer necessities AND the person's particulars (abilities, expertise, time estimate), summarize this info clearly for the Price Recommender. Sign that you've got all crucial data.
   """,
)

3. Price Recommender Agent

The Price Recommender Agent makes use of the collected info to generate an in depth mission proposal. It waits for the entire abstract from the Scope Architect. Then analyzes the mission scope and freelancer particulars to generate an expert proposal doc. This features a customized introduction, a timeline, a number of pricing tiers, and a transparent name to motion.

Anticipated Output:

• Professionally formatted mission proposal doc with a scope, pricing, and subsequent steps.
• The ultimate output is able to be delivered to the consumer for approval or additional dialogue.

rate_recommender_agent = autogen.AssistantAgent(
   identify="Rate_Recommender",
   llm_config=llm_config,
   max_consecutive_auto_reply=1, # Solely reply as soon as
   system_message=f"""
You're a Proposal Generator and Price Recommender. Your activity is to create a structured mission proposal.
Wait till the Scope_Architect shares a abstract containing BOTH the consumer's mission necessities AND the person's profile (abilities, expertise, time estimate, previous work if accessible).
Analyze all acquired information: consumer wants, person experience, estimated time, and any prior price insights.
Generate a well-structured proposal addressed to the consumer, together with the next sections:
Customized Introduction: Professionally introduce the person's companies and reference the consumer's firm and mission.
Challenge Scope & Timeline: Clearly define the deliverables with estimated timelines based mostly on person enter.
Recommended Pricing Tiers: Present 1–3 pricing choices (hourly, fastened charge, retainer) with justifications based mostly on scope, person expertise, or complexity.
Subsequent Steps (CTA): Advocate scheduling a short kickoff name to finalize and make clear particulars.
Current ONLY the ultimate formatted proposal. Don't embrace extra commentary except clarification is requested.""",)

4. Consumer Proxy Agent

This agent acts as an entry level or helper to kick off the interplay. Although it doesn’t play a central position on this circulation (based mostly on the code supplied), it may very well be used to provoke or help with user-facing duties.

user_proxy = autogen.UserProxyAgent(
   identify="user_proxy",
   max_consecutive_auto_reply=1,
   # is_termination_msg=lambda x: x.get("content material", "").rstrip().endswith("TERMINATE"),
   llm_config=llm_config,
   system_message="""you're an useful assistant and initate the dialog"""
)

Step 4: Creating the Group Supervisor

This step units up the central coordinator that manages communication and teamwork between all specialised brokers.

1. Setting Up Group Chat

The Group Chat establishes a structured dialog atmosphere for 3 specialised brokers. These are the consumer agent, scope architect agent, and price recommender agent. It manages dialog circulation by means of spherical limits and orderly speaker choice.

Key factors:

• Homes three specialised brokers working towards proposal creation
• 4 rounds most to take care of focus
• “Round_robin” talking sample ensures orderly participation
• Creates a managed atmosphere for gathering info

# --- Group Chat Setup ---
groupchat = autogen.GroupChat(
   brokers=[client_agent, scope_architect_agent, rate_recommender_agent],
   messages=[],
   max_round=4,
   speaker_selection_method="round_robin",
)

2. Creating the Group Chat Supervisor

The Group Chat Supervisor orchestrates your entire dialog, guiding interactions by means of a logical development from mission particulars to proposal era. Its system message offers step-by-step directions for agent interactions and defines clear termination situations.

Key factors:

• Directs dialog circulation between all brokers
• Hyperlinks to the Group Chat object
• Maintains constant LLM configuration
• Incorporates detailed course of directions
• Terminates upon proposal completion or with the TERMINATE command

supervisor = autogen.GroupChatManager(
   groupchat=groupchat,
   llm_config=llm_config,
   # System message for the supervisor guiding the general circulation
   system_message="""Handle the dialog circulation between the brokers.
   1. Begin with the Client_Input_Agent offering mission particulars.
   2. Make sure the Scope_Architect asks the required questions in regards to the person's background.
   3. Make sure the Client_Input_Agent relays the person's solutions.
   4. Make sure the Rate_Recommender waits for all data earlier than producing the ultimate proposal within the specified format.
   The dialog finishes when the ultimate proposal is generated or the Client_Input_Agent says TERMINATE."""
)

Step 5: Initiating the Chat

Now that we now have the brokers in place, let’s provoke the collaborative workflow between the brokers. For this, we are going to ship a transparent instruction immediate to the GroupChatManager from the user_proxy agent.

Key factors:

• Triggers the dialog through the use of user_proxy.initiate_chat(), which begins the group chat and sends the message to the GroupChatManager.
• Delegates management to the supervisor, which then follows the step-by-step circulation utilizing the round-robin methodology and its inside system message directions to coordinate the brokers.

# --- Provoke Chat ---


print("Beginning the proposal era course of...")
print("Please present the preliminary consumer and mission particulars when prompted.")


initial_prompt_message = """
Begin the method. First, I would like the consumer/mission particulars from the person (through Client_Input_Agent).
Then, Scope_Architect ought to ask the person (through Client_Input_Agent) about their background.
Lastly, Rate_Recommender ought to generate the proposal.
"""


user_proxy.initiate_chat(
   supervisor,
   message=initial_prompt_message
)

Step 6: Formatting the Output

This code will assist us current the output in a markdown(.md) format.

chat_history = supervisor.chat_messages[client_agent] # Or probably simply supervisor.chat_messages if construction differs barely


# Discover the final message from the Rate_Recommender agent
final_proposal_message = None
for msg in reversed(chat_history):
   if msg.get("position") == "assistant" and msg.get("identify") == rate_recommender_agent.identify:
        if "Customized Introduction:" in msg.get("content material", ""):
           final_proposal_message = msg
           break
if final_proposal_message:
   final_proposal_string = final_proposal_message.get("content material", "Proposal content material not discovered.")
   attempt:
       show(Markdown(final_proposal_string))
   besides NameError:
       print("n(Displaying uncooked Markdown textual content as wealthy output is unavailable)n")
       print(final_proposal_string)


else:
   print("nCould not routinely extract the ultimate proposal from the chat historical past.")
   print("You might must assessment the complete chat historical past above.")
