💡 Hint

Common Mistakes

Choosing a tool unrelated to calculations.

The agent uses the 'calculator' tool to perform calculations, extending its capability beyond basic responses.

💡 Hint

Common Mistakes

Choosing tools unrelated to language processing.

Adding the 'translator' tool allows the agent to understand and convert languages, extending its abilities.

3fill in blank

hard

Fix the error in the code where the agent tries to use a tool but the tool name is missing.

💡 Hint

Common Mistakes

Leaving the tool name empty or None.

The agent must specify a valid tool name like 'search_engine' to execute a task properly.

4fill in blank

hard

Fill both blanks to create a dictionary mapping tools to their functions.

💡 Hint

Common Mistakes

Using incorrect attributes that don't represent name or function.

Using 'tool.name' as the key and 'tool.function' as the value correctly maps each tool to what it does.

5fill in blank

hard

Fill all three blanks to filter tools that extend agent capabilities and create a summary dictionary.

Agentic AI

extended_tools = {tool.[1]: tool.[2] for tool in all_tools if tool.[3]

💡 Hint

Common Mistakes

Using attributes that don't represent name, function, or active status.

This code creates a dictionary of active tools by mapping their names to their functions, showing how tools extend agent capabilities.

Practice

1. Why do agents use tools to extend their capabilities?

easy

A. To perform tasks beyond their built-in skills

B. To reduce their processing speed

C. To limit the information they can access

D. To avoid learning new skills

Solution

1. Step 1: Understand agent built-in skills

   Agents have a set of skills they can perform on their own, but these are limited.

2. Step 2: Role of tools in extending capabilities

   Tools allow agents to do more by accessing new information or performing special tasks beyond their built-in skills.

3. Final Answer:

   To perform tasks beyond their built-in skills -> Option A

4. Quick Check:

   Tools extend agent skills = C [OK]

Hint: Tools add new skills to agents quickly [OK]

Common Mistakes:

• Thinking tools slow down agents
• Believing tools limit agent abilities
• Assuming agents avoid new skills

2. Which of the following is the correct way to describe how an agent uses a tool?

easy

A. Agent ignores tools and works alone

B. Agent replaces its core skills with tools

C. Agent calls a tool to perform a specific task

D. Agent disables tools after learning

Solution

1. Step 1: Understand agent-tool interaction

   Agents use tools by calling them when a task requires capabilities beyond their own.

2. Step 2: Identify correct description

   Calling a tool to perform a specific task matches how agents extend their abilities.

3. Final Answer:

   Agent calls a tool to perform a specific task -> Option C

4. Quick Check:

   Agent uses tools by calling them = B [OK]

Hint: Agents call tools to help with tasks [OK]

Common Mistakes:

• Thinking agents ignore tools
• Believing tools replace core skills
• Assuming tools are disabled after use

3. Given this code snippet, what will the agent output?

tools = {'calculator': lambda x, y: x + y}
agent_skills = ['chat']

# Agent uses calculator tool
result = tools['calculator'](3, 4)
print(f'Result: {result}')

medium

A. Error: tools not found

B. Result: 34

C. Result: calculator

D. Result: 7

Solution

1. Step 1: Understand the tool function

   The 'calculator' tool is a function that adds two numbers x and y.

2. Step 2: Calculate the result of the tool call

   Calling tools['calculator'](3, 4) returns 3 + 4 = 7.

3. Final Answer:

   Result: 7 -> Option D

4. Quick Check:

   3 + 4 = 7 [OK]

Hint: Check what the tool function does with inputs [OK]

Common Mistakes:

• Concatenating numbers as strings
• Confusing tool name with output
• Assuming tools dictionary is missing

4. Find the error in this agent-tool usage code:

tools = {'search': lambda query: 'results for ' + query}

# Agent tries to use tool
output = tools['search'](123)
print(output)

medium

A. The tools dictionary is empty

B. The tool function expects a string, but got a number

C. The agent forgot to call the tool

D. The print statement is missing parentheses

Solution

1. Step 1: Check tool function input type

   The 'search' tool concatenates 'results for ' with the input query, expecting a string.

2. Step 2: Identify input type mismatch

   The code passes 123 (a number), which causes a type error when concatenating with a string.

3. Final Answer:

   The tool function expects a string, but got a number -> Option B

4. Quick Check:

   String concat needs string input = A [OK]

Hint: Check input types for string operations [OK]

Common Mistakes:

• Ignoring input type mismatch
• Assuming tools dictionary is empty
• Thinking print syntax is wrong

5. An agent has built-in skills for chatting but needs to answer math questions. Which approach best extends its capabilities using tools?

hard

A. Add a calculator tool the agent can call for math tasks

B. Rewrite the agent to learn math from scratch

C. Disable chatting skills to focus on math

D. Ignore math questions to avoid errors

Solution

1. Step 1: Identify agent's current skills and needs

   The agent can chat but lacks math skills needed to answer math questions.

2. Step 2: Choose the best way to extend capabilities

   Adding a calculator tool allows the agent to handle math tasks without losing chat skills or needing full retraining.

3. Final Answer:

   Add a calculator tool the agent can call for math tasks -> Option A

4. Quick Check:

   Tools add needed skills without retraining = D [OK]

Hint: Add tools for missing skills, not rewrite agent [OK]

Common Mistakes:

• Thinking agent must relearn all skills
• Disabling useful existing skills
• Ignoring tasks agent can't do
