Tool selection by the agent in Agentic AI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to select the correct tool based on the task description.

Agentic AI

tool = agent.select_tool([1])

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

A'task_description'

B'task'

C'tool_name'

D'input_data'

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'tool_name' instead of the task description.

Passing input data instead of the task.

The agent selects a tool based on the 'task_description' parameter describing what needs to be done.

2fill in blank

Complete the code to execute the selected tool with the given input.

Agentic AI

result = selected_tool.[1](input_data)

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

Capply

Dexecute

💡 Hint

Common Mistakes

Using 'run' which might not be defined for the tool object.

Using 'apply' which is less common for tool execution.

The method 'execute' is commonly used to run the selected tool on input data.

3fill in blank

hard

Fix the error in the code to correctly check if the tool supports the required capability.

Agentic AI

if [1] in selected_tool.capabilities:

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

Acapabilities

Brequired_capability

Ccapability_name

Dcapability

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'capabilities' which is the list, not the item to check.

Using 'capability' which is too generic and undefined.

The variable 'required_capability' holds the capability to check for in the tool's capabilities list.

4fill in blank

hard

Fill both blanks to create a dictionary mapping tool names to their descriptions for tools that support the required capability.

Agentic AI

tool_info = {tool.name: tool.[1] for tool in tools if [2] in tool.capabilities}

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

Adescription

Brequired_capability

Ccapability

Ddetails

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'capability' instead of 'required_capability' for filtering.

Using 'details' which might not be the correct attribute for description.

We want the tool's description and check if the required_capability is in the tool's capabilities.

5fill in blank

hard

Fill all three blanks to create a function that selects a tool by name, checks if it supports the required capability, and executes it with input data.

Agentic AI

def use_tool(tools, name, [1], input_data):
    tool = next((t for t in tools if t.name == name), None)
    if tool and [2] in tool.capabilities:
        return tool.[3](input_data)
    return None

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

Arequired_capability

Cexecute

Drun

Attempts:

3 left

💡 Hint

Common Mistakes

Using different variable names for capability in the function signature and check.

Using 'run' instead of 'execute' which might not be defined.

The function uses 'required_capability' to check capabilities and calls 'execute' to run the tool.

Practice

1. What is the main purpose of tool selection by an AI agent?

easy

A. To choose the best helper tool for a specific task

B. To train the AI model faster

C. To store data securely

D. To improve the hardware performance

Solution

1. Step 1: Understand the role of tool selection

   Tool selection means picking the right tool or helper for the AI to complete a task well.

2. Step 2: Match purpose with options

   Among the options, only choosing the best helper tool fits the idea of tool selection.

3. Final Answer:

   To choose the best helper tool for a specific task -> Option A

4. Quick Check:

   Tool selection = choosing best tool [OK]

Hint: Tool selection means picking the right tool for the job [OK]

Common Mistakes:

• Confusing tool selection with training the model
• Thinking it improves hardware
• Mixing it with data storage

2. Which of the following is the correct way to check if a tool named calculator should be used for a task containing the word 'math'?

easy

A. if calculator in task_description: use math

B. if task_description == 'calculator': use math

C. if 'math' in task_description: use calculator

D. if 'calculator' == task_description: use math

Solution

1. Step 1: Understand keyword check syntax

   To check if 'math' is in the task description, use 'math' in task_description.

2. Step 2: Match correct syntax with options

   if 'math' in task_description: use calculator correctly uses this syntax to decide to use the calculator tool.

3. Final Answer:

   if 'math' in task_description: use calculator -> Option C

4. Quick Check:

   Keyword in string check = if 'math' in task_description: use calculator [OK]

Hint: Use 'keyword' in string to check presence [OK]

Common Mistakes:

• Using equality instead of containment
• Checking wrong variable names
• Confusing tool and task names

3. Given the code below, what will be printed?

tools = ['calculator', 'translator', 'weather']
task = 'translate this sentence'
selected_tool = None
for tool in tools:
    if tool in task:
        selected_tool = tool
        break
print(selected_tool)

medium

A. calculator

B. translator

C. weather

D. None

Solution

1. Step 1: Loop through tools and check if tool name is in task

   The loop checks if 'calculator', 'translator', or 'weather' is in the task string 'translate this sentence'.

2. Step 2: Identify which tool matches the task

   None of the tool names appear as substrings in the task ('translator' is not in 'translate this sentence'), so selected_tool remains None.

3. Final Answer:

   None -> Option D

4. Quick Check:

   No substring match, prints None [OK]

Hint: Check substring presence carefully in loops [OK]

Common Mistakes:

• Assuming exact word match needed
• Ignoring break statement
• Thinking 'translator' matches 'translate'

4. The following code is meant to select a tool based on keywords, but it always prints None. What is the error?

tools = {'calc': 'calculator', 'trans': 'translator'}
task = 'please compute this'
selected_tool = None
for key in tools:
    if key in task:
        selected_tool = tools[key]
print(selected_tool)

medium

A. The print statement is outside the loop

B. The keys 'calc' and 'trans' do not match any substring in the task

C. The loop should use tools.values() instead of keys

D. The dictionary keys should be full tool names, not abbreviations

Solution

1. Step 1: Check if keys are substrings of the task

   The keys are 'calc' and 'trans'. The task is 'please compute this'. Neither 'calc' nor 'trans' is a substring.

2. Step 2: Understand why selected_tool stays None

   Since no key matches, the if condition never runs, so selected_tool remains None.

3. Final Answer:

   The keys 'calc' and 'trans' do not match any substring in the task -> Option B

4. Quick Check:

   Substring match fails due to partial keys [OK]

Hint: Check if keys exactly appear as substrings in task [OK]

Common Mistakes:

• Assuming partial matches work
• Thinking print location causes error
• Confusing keys with values

5. You want an AI agent to select tools based on multiple keywords in a task. Which approach best fits this need?

hard

A. Check each tool's keywords and select the tool with the most keyword matches

B. Always select the first tool in the list regardless of task

C. Select a tool randomly without checking the task

D. Use only one keyword per tool and ignore others

Solution

1. Step 1: Understand the need for multiple keyword matching

   When tasks have multiple keywords, the agent should consider all keywords to pick the best tool.

2. Step 2: Evaluate options for best fit

   Check each tool's keywords and select the tool with the most keyword matches uses multiple keyword checks and picks the tool with the most matches, which is the best approach.

3. Final Answer:

   Check each tool's keywords and select the tool with the most keyword matches -> Option A

4. Quick Check:

   Best tool = most keyword matches [OK]

Hint: Count keyword matches to pick best tool [OK]

Common Mistakes:

• Ignoring multiple keywords
• Picking tools randomly
• Always choosing first tool
