Practice - 5 Tasks

1fill in blank

easy

Complete the code to send a message from one agent to another using the basic send method.

Agentic AI

agent.send([1])

Drag options to blanks, or click blank then click option'

A"Hello, Agent!"

Bmessage

Creceive()

Dconnect()

💡 Hint

Common Mistakes

Passing a variable instead of a string literal.

Using receive() instead of send().

Calling connect() which is unrelated here.

The send method requires the message content as a string argument to send it to another agent.

2fill in blank

medium

Complete the code to receive a message from another agent.

Agentic AI

incoming = agent.[1]()

Drag options to blanks, or click blank then click option'

Bsend

Creceive

Dlisten

💡 Hint

Common Mistakes

Using send() instead of receive().

Trying to use connect() which is for establishing connections.

Using listen() which is not a standard method here.

The receive() method is used to get messages sent by other agents.

3fill in blank

hard

Fix the error in the code to broadcast a message to all connected agents.

Agentic AI

agent.[1]("Broadcast message")

Drag options to blanks, or click blank then click option'

Abroadcast

Bsend

Creceive

Dconnect

💡 Hint

Common Mistakes

Using send() which only sends to one agent.

Using receive() which is for incoming messages.

Using connect() which is for establishing connections.

The broadcast() method sends a message to all connected agents at once.

4fill in blank

hard

Fill both blanks to check if the agent is connected and then send a message.

Agentic AI

if agent.[1]():
    agent.[2]("Status update")

Drag options to blanks, or click blank then click option'

Ais_connected

Bsend

Creceive

Dconnect

Attempts:

3 left

💡 Hint

Common Mistakes

Using receive() instead of send() to send messages.

Using connect() instead of is_connected() for checking status.

First check if the agent is connected using is_connected(), then send the message with send().

5fill in blank

hard

Fill all three blanks to create a message dictionary with sender, receiver, and content keys.

Agentic AI

message = {
    "sender": [1],
    "receiver": [2],
    "content": [3]
}

Drag options to blanks, or click blank then click option'

A"agent_1"

B"agent_2"

C"Hello there!"

D"status"

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up sender and receiver values.

Using status instead of a greeting message for content.

The message dictionary needs sender as "agent_1", receiver as "agent_2", and content as "Hello there!".

Practice

1. What is the main purpose of agent communication protocols in AI systems?

easy

A. To allow AI agents to share messages clearly and work together

B. To store large amounts of data efficiently

C. To speed up the training of machine learning models

D. To create visualizations of AI decisions

Solution

1. Step 1: Understand the role of communication protocols

   Agent communication protocols define how AI agents send and receive messages to coordinate actions.

2. Step 2: Identify the main goal

   The main goal is to enable clear message sharing so agents can work together effectively.

3. Final Answer:

   To allow AI agents to share messages clearly and work together -> Option A

4. Quick Check:

   Communication protocols = clear message sharing [OK]

Hint: Protocols help agents talk clearly to cooperate [OK]

Common Mistakes:

• Confusing communication with data storage
• Thinking protocols speed up training
• Assuming protocols create visualizations

2. Which of the following correctly shows the basic components of a message in agent communication protocols?

easy

A. Sender, Receiver, Content, Speed, Type

B. Sender, Password, Content, Time, Type

C. Sender, Receiver, Content, Size, Color

D. Sender, Receiver, Content, Time, Type

Solution

1. Step 1: Recall message components

   Messages include sender, receiver, content, time, and type to describe communication details.

2. Step 2: Match components with options

   Sender, Receiver, Content, Time, Type lists all correct components; others include incorrect or irrelevant parts like password, size, color, or speed.

3. Final Answer:

   Sender, Receiver, Content, Time, Type -> Option D

4. Quick Check:

   Message parts = sender, receiver, content, time, type [OK]

Hint: Remember message parts: who, to whom, what, when, kind [OK]

Common Mistakes:

• Including unrelated fields like password or color
• Confusing message size with time
• Mixing up message type with speed

3. Given this message dictionary in Python representing an agent message:

message = {"sender": "AgentA", "receiver": "AgentB", "type": "request", "content": "status update", "time": "10:00"}

What will message["type"] return?

medium

A. "status update"

B. "AgentA"

C. "request"

D. "10:00"

Solution

1. Step 1: Identify the key being accessed

   The code accesses the value for the key "type" in the message dictionary.

2. Step 2: Find the value for "type"

   In the dictionary, "type" has the value "request".

3. Final Answer:

   "request" -> Option C

4. Quick Check:

   message["type"] = "request" [OK]

Hint: Look up the key exactly in the dictionary [OK]

Common Mistakes:

• Confusing key names and values
• Selecting sender or content instead of type
• Misreading dictionary syntax

4. Consider this Python code snippet for sending a message between agents:

def send_message(sender, receiver, content):
    message = {
        "sender": sender,
        "receiver": receiver,
        "content": content,
        "time": time.now(),
        "type": "info"
    }
    return message

What is the error in this code?

medium

A. Incorrect use of time.now() instead of datetime.now()

B. Missing return statement

C. Missing import for time module

D. Wrong dictionary keys used

Solution

1. Step 1: Check the time function usage

   The code uses time.now(), but the time module does not have a now() function.

2. Step 2: Identify correct function for current time

   The correct function is datetime.now() from the datetime module.

3. Final Answer:

   Incorrect use of time.now() instead of datetime.now() -> Option A

4. Quick Check:

   Use datetime.now() for current time [OK]

Hint: Use datetime.now(), not time.now() for timestamps [OK]

Common Mistakes:

• Assuming time module has now()
• Forgetting to import datetime
• Thinking return is missing

5. You want two AI agents to coordinate a task by exchanging messages. Agent A sends a request message asking for data, and Agent B replies with a response message containing the data. Which protocol design best supports this interaction?

hard

A. Use only 'info' message type and ignore sender and receiver fields

B. Define message types like 'request' and 'response' with sender, receiver, content, and timestamp fields

C. Send messages without specifying type or time to reduce complexity

D. Use random message types and rely on content keywords to guess meaning

Solution

1. Step 1: Understand the need for clear message types

   Using defined message types like 'request' and 'response' helps agents know the purpose of each message.

2. Step 2: Recognize importance of sender, receiver, content, and time

   These fields ensure messages are directed correctly, understood, and tracked over time.

3. Final Answer:

   Define message types like 'request' and 'response' with sender, receiver, content, and timestamp fields -> Option B

4. Quick Check:

   Clear message types + fields = effective coordination [OK]

Hint: Use clear message types and full fields for teamwork [OK]

Common Mistakes:

• Ignoring message types causes confusion
• Skipping sender/receiver leads to lost messages
• Relying on content guessing is unreliable
